Frequently Asked Questions

• What is HDfury ?

The HDfury is a tiny external add-on adapter that is used to add a digital DVI/HDMI input to older display devices without digital inputs so that the newest sources such as HD-DVD/Blu-ray players can used.It is connected to any RGB display through the SUB-D HD15 (VGA) Female Input or RGBHV BNC inputs using an optional extender cable. Once in place the HDfury performs HDCP decryption and HDMI to RGB conversion. You can then connect any HDMI source in full HD 1080p directly to your now “enhanced” display!

• Why do i need HD (720p) or Full HD (1080p)?

HD-DVD players, Blu-Ray players, HDMI graphic cards, PS3, Xbox 360 Elite are all able to unleash their true potential (720p/1080p mode) only through the HDMI output. If you want a valid ticket to the Full HD world you either need a compatible display (with HDMI input) or a solution for your existing display.

• Why do i need a HDCP compliant display?

HDMI is a new standard that comes with a form of hardware protection called HDCP. If your display doesn’t have a HDMI input you won’t be able to display 720p/1080p signal on it (from HDMI sources). Prior to exchanging Video data, the HDMI source exchanges HDCP keys with HDMI display. Both devices have a special HDCP chip embedded. If your display doesn’t include an HDCP chip, even if it’s technically able to display 720p or 1080p signal, it will display a BLACK SCREEN. On some devices (ex: Playstation3, Xbox360) 1080p mode is only available through the HDMI output!

• Prior the HDfury, what could I do if my display was not HDCP compliant?

You had to either buy a new display with an HDMI input or use a HDCP stripper/converter box which remove HDCP protection and output analog RGB. These boxes have the following issues/problems:
- They need extra wires for the power supply and analog cables.
- Often switches or settings need to be tweaked.
- Quality is limited and restricted because of the longer analog link.
- They are not compliant to HDCP rules as they allow easy access to the decrypted analog video.

• What are the advantages of using HDfury?

- HDfury can screw directly to your display therefore (unlike the stripper/converter boxes) it remains compliant to the HDCP rules as it does not allow and end-user easy access to the analog decrypted signal.
- It can therefore be used and sold legally to transform any RGB display into a HDCP compliant display.
- Shortest analog link possible ensures the highest video quality possible!
- Aluminum and gold plated materials.
- It does not require external power supply to operate.

• Does the HDfury change the resolution? Upconvert or downcovert?

The HDfury does not change the resolution or refresh rate in any way. It simply converts the digital input signal to an analog RGBHV (VGA) signal. It also provides HDCP decryption if needed. The HDfury outputs whatever resolution you feed it. Absolutely nothing is changed. In other words, if you feed the HDFury a 720p/60Hz digital signal the only thing it will output is a 720p/60Hz analog signal. Feed the HDfury a 1080p/60Hz signal and it’ll output a 1080p/60Hz signal… and so on.

• I use component cables to connect my HD-DVD/Blu-Ray player to my display device and it works just fine! Why do I need HDfury?

HD-DVD and Blu-Ray players can also upconvert standard definition DVDs to higher resolutions (720p, 1080i, 1080p), but they only do this via the HDMI outputs (not component). So if you want to get the higher resolution benefits of your player’s upconversion circuitry, you’re forced to use HDMI. As well, in the future it may not be possible to pass certain high definition content over component video cables. A content flag called the ICT (Image Constraint Token) allows broadcasters and movie studios to limit or “down-res” the HD video signal to standard definition 480P resolution over component video cables. This is not something that has been activated yet, but it could be used at some point in the future. And the most important reason to use HDfury: The picture quality is substantially better! (Sharper/cleaner/less noise/less ringing/etc). Read the reviews above for some examples!

• My display has composite (ie: combined) sync with only 4 BNC inputs not 5. (Examples: Barco 7xx/Cine7 or Ampro). What cable do I order? How do I hook it up?

Order the GREEN (5-BNC breakout cable) and combine the H/V sync lines using a $2 BNC T-connector like this. You could also use an Extron 109 or 202 box as well to combine the two sync lines.

• My Barco requires negative sync to work. Does the HDfury output negative sync?

The HDfury does not alter the signal that it is fed in any way. If it is fed a negative sync signal, it will output a negative sync signal. If it is fed a positive sync signal, it will output a positive sync signal. You can use boxes from Extron or Altinex to invert the sync if required. To alter the sync to make it work with your projector, add an RTC2200 box to your HDfury setup. It adds others benefits (Center Picture and Gamma Adjustement) to the HDfury in addition to providing adjustable sync.

• I have a scaler or doubler (ex: Lumagen) with DVI inputs and an RGBHV output connected to my display device. I don’t need an HDfury right?

Incorrect. You still need the HDfury if you want to use HDMI sources such as HD-DVD and Blu-Ray players that may have HDCP-protected content. The scaler, by law, is not allowed to output content via RGB if the source content is HDCP protected. The scaler will simply TURN OFF its analog RGB output. Only the digital DVI/HDMI outputs will remain on. To solve this, connect the HDfury to the DVI output of your scaler, and then connect the HDfury to your display device. Simple!

• I have a scaler or doubler (ex: Lumagen) with DVI inputs and a DVI/HDMI output connected to my display device’s DVI input. I don’t need an HDfury right?

Maybe. You still need the HDfury if you want to use HDMI sources such as HD-DVD and Blu-Ray players that may have HDCP-protected content *and* your display device does not have an HDMI input. The scaler, by law, must pass the HDCP-protected content all the way to your display device. The display device must decrypt the content. If your display device only has a DVI input, it will not decode HDCP. To solve this, connect the HDfury to the DVI output of your scaler, and then connect the HDfury to your display device. Simple!

• I want to connect a longer cable to the output of the HDfury. Can I do that?

No. Keep the analog cable between the HDfury’s output and the device it is connected to as SHORT as possible. Only use the HDfury plugged directly into a display device, or use one of the 3 very short (4-6″) RED/GREEN/BLUE high quality extender cables that comes with the HDfury. Failing to do so will result in a lesser than optimal image quality. Reason: The HDfury was not built to drive cables as it does not have an output stage. If you can’t keep the HDfury close to the display device, no problem! Keep the cable short by plugging it into your scaler passthrough, transcoder with passthrough, your switcher, Extron booster, or any other device with an output stage meant to drive longer cables.
If you really want to use a longer output cable to your HDfury, add an RTC2200 box to your HDfury setup. It also adds others benefits (Gamma Adjustement, Center Screen) to the HDfury in addition to providing the ability to drive longer cables.

• The specs say that the HDfury draws it’s power directly from the DVI/HDMI line but that an optional +5VDC input is provided for HDMI cables that are over 5 meters (16 feet) or if the source device is unable to supply adequate power. What sort of power supply do I need for this? When do I need to use an external power supply?

The DC jack on the side of the HDfury must follow all these requirements:
- Provide REGULATED (+/- 5%) 5VDC power with 0.5A min DC current
- Deliver the power through a small 0.65mm diameter center pin / 2.6mm outer diameter DC plug (like the one often used in cellular phone AC adaptor)
- Provide the correct polarity with ‘plus’ on the OUTER part of the plug and ‘minus’ (ground) on the small center pin of the DC jack.
Trying to use an AC/DC adaptor that doesn’t follow all these three requirements may destroy the HDFury. This external HDFury powering option is only needed in one or both the following situations:
- The DVI or HDMI cable is using thin gauge copper wires and its length exceeds 5 meters (16 feet).
- The DVI or HDMI source is unable to deliver the 0.5A maximum current over its HDMI or DVI pin #14. This situation often occurs when HDFury is used with cheap DVD/HD players at 1080p60 mode.
Update: The picture quality is often also improved by using an external power supply. Users are reporting that using an external power supply results is a punchier image. For this reason we are highly suggesting that everyone looking for the best image quality possible always order the HDFury Advanced package as it ships with a power supply and some other extras.

• Does the HDfury support 1080p/24fps found in next generation HD-DVD and Blu-Ray players?

Yes! The HDfury simply converts the input signal from DVI-D digital to RGBHV analog (and applies HDCP decryption if required). It doesn’t change the the resolution or refresh rate – it simply passes it through. As long as you stay under the 1080p/60 bandwidth requirement (ie: the 165Mhz pixel clock rate), it doesn’t care what the resolution or refresh rate is.

• I connected my HDfury but the image is shifted to the left. How do I fix it?

The picture is shifted to the left is normal when you connect HDfury for the first time. Simply adjust your display’s settings to shift the image back. This needs to only be done once. On some European CRT displays you will not be able to shift back far enough because of the US/Euro HD ‘porch’ differences. If this affects you, switch your source to 60Hz to solve the problem. You can setup a new memory and it won’t disturb any of your original settings. As the HDfury comes with his own EDID, you will always have the H position to adjust. For example, you can connect HDfury to your PC VGA screen, and you will see that the first time the picture is shifted to the left. You can then adjust this setting on your PC display, and it will be perfect. If you connect your computer back to the PC VGA screen, the image will centered as before! Your screen / display has memory functions to store your settings depending on the source. There is no other settings to adjust. If you need to shift the image back and cannot do so with your projector, add an RTC2200 box to your HDfury setup. It adds many benefits to the HDfury in addition to providing image shifting capabilities.

• My picture is cropped (cut off). How do I fix it?

See the last question. The image is likely only shifted slightly. The HDFury doesn’t process the incoming digital video stream to ‘cut’ the image. The HDfury remains synchronous the the pixelclock of the digital video inputed (no process, no frame buffer, ….). It just converts the digital pixel data to analog, nothing else. If the picture is truly cropped, then, this is due to the source device. If you need to shift the image back and cannot do so with your projector, add an RTC2200 box to your HDfury setup. It adds many benefits to the HDfury in addition to providing image shifting capabilities.

• The black level (brightness) on my display device is constantly changing causing dark and light scenes to change in black level. How do I fix it?

Your display device may have poor black level clamping and you will therefore see this problem with any source device with or without the HDfury. If you have a way of adjusting it, try to adjust the ‘Clamp’ setting of your display to ‘H/C’ (horizontal/composite sync) mode rather than ‘Auto’. Not all displays will have this setting. Many consumer displays will have this hidden in a service menu.

• My projector or display device has a 3-prong power cable with a ground pin. I’ve bypassed the the ground pin. Is this a problem?

YES! Not only is this very dangerous to you (the homeowner) you may damage your HDfury and/or your display. Your HDfury warranty is null and void if you bypass the grounding of your display device. Please do not do this! Bypassing ground pins because of ground loop problems, hum problems, or other reasons is very dangerous and only masks the problem. You need to fix the source of the problem. The ground pin is there for your safety and for the safety of your equipment.

• I’m still getting a black screen from my PS3 when using the HDfury. How can I fix this?

The problem is that you likely connected the HDfury to the HDMI port while the PS3 was still setup to output by another port (component or composite). The result is no picture over HDMI. The PS3 will output low resolution on every output when you reset the display settings this way: PS3 in stand by mode, hold on power for 5 sec until you heard 3 beeps.
The PS3 restarts and you can than access low resolution through both HDMI and/or other ports and perform the display test to choose your preferred resolution.

• I need a different extender cable or want to buy some extra cables or power supply. Can I do this?

Yes! Anyone may order BLUE/GREEN/RED extender cables, power supplies, or HDMI-to-DVI cables separately on the HDfury order page. In fact, many people order the VGA to BNC breakout (GREEN) cable to use in other applications as it’s a very good quality short cable. is All orders include at least one free 6′ USB 5V cable for powering the HDfury from any USB port.

• Is the actual HDfury device used in the various packages the same or are there difference types of HDfury devices available?

There is only one type of HDfury converter available. The same one is used in every package. The various packages only differ in the types of extender cables and accessories offered. If your setup changes and you need a different extender cable or accessory, you may order them separately on the HDfury order page.

“I am so glad I did my homework and found this device through Curt Palme’s site. This saved me from upgrading to a HDMI projector. I can now take full advantage of the 1080P upscaling for standard DVD on my Samsung Bluray player and my HD movies look absolutely amazing. This is a must have option. I cannot believe how quickly it arrived from Taiwan to Courtice Ontario Canada . 4 Business days! It is simple to setup and works as advertised. I will have to tell everyone about this mini wonder of technology!” – Alan B.

 

“From what I’ve been watching and observing with an HDfury/BluRay player so far, the HDfury is a HUGE difference from the previous DVI units. From everything that I could throw through it using the BluRay DVD’s that I have, it’s flawless. Clean and very tight. Unlike the other DVI units, it’s not showing the common color space issues that I’ve seen on all of them. Nor does it have pedestal problems, which is also a common problem on these devices. The most impressive improvement over the other units, was the linear IRE range. I’m not seeing the usual crushing issue at one end or the other. It’s flawless. I’m not a fan of the DVI units: Until yesterday, I’ve not seen one worth connecting to my projector. Now I’m a complete convert… Kudos!” – CRT projector guru Mike Parker of MPmods.com

 

“I ordered one from Curt’s site, and got it today. I’ve got to hand it to ya John, this thing works BEAUTIFULLY!! I hooked up my PS3 to my 24″ CRT and it locked on to 1080p FLAWLESSLY! I’ve never seen such a beautiful image before! Thanks again for a quality product! “ – Traxx

 

“Well, mine has arrived also. It is a little thicker than it looks online. Packaging is very good looking. But, who cares about that? I just want it to work well. And that it does. Mated with the RTC2200 (which provides a gamma boost) in my set up it was exceptionally clean and sharp. It solves the very slight softening I had with the Ophit. Bottom line, it is excellent. It does what it should and does it exceptionally well. Both Corpse Bride and Riddick HD DVDs were so crisp on my system, no one would ever doubt CRT sharpness if you saw my setup! Thanks John, great work. Excellent product Franck and thanks for the incredible customer service. My opinion if anyone cares: 5 thumbs up!“ – Dave (Person99)

 

“It works as promised and hasn’t added anything to the picture that is not supposed to be there so far… it has improved the picture slightly than the previous DVIlink unit I had in the mix before.” – Big hitter

 

“HDFury has me smiling from ear to ear!! I’m going to be stupidly happy all week and likely beyond. My video chain is PS3 to HDFury via HDMI/DVI and then into a Sony G70 with a short cable. When I plugged it in and turned it on the PS3 determined I had HDMI and setup 1080p automatically with a 3min setup I was completely impressed. I’ve heard about problems with HDMI but I guess I’ll never get to experience them because this setup is perfect right out of the gate. I can already say I’m 100% satisfied and my expectations were high to the point of silliness. I would recommend this product to anyone with CRT FP and/or anyone with a PS3. Trouble-Free HDMI to VGA: The HDFury works just as it should. I have no HDMI problems whatsoever. Even with my 26AWG, 25Foot, $20 HDMI/DVI cable (If I had to buy it again I would have opted for the $30 thicker cable just for peace of mind) I never see any of the problems I’ve read about others having with HDMI. I see no need to buy the power cable to provide additional current to the HDFury. Value: The cost is terrific for the quality of the product. And it’s universal nature is a great feature for a CRT front projector enthusiast because if you change or upgrade your projector you still have a HDCP solution ready to go. Image Quality: The image quality is great. I don’t have any other HDMI to VGA solutions to compare it too because this was the first one I felt I could afford and yet I think it’s going to rate well against the competition simply because the image quality it produces looks top notch to me.” – Brian Hampton

 

“Got my ‘Green Edition’ yesterday afternoon (Jul 13, 2007), direct-shipping from Taiwan. Curious as I am I had to try out how it’s working. And what can I say, that’s what I really call plug and play. Linked the thing with the 5-BNC-input of my DLP-projector, connected it with a HDMI-to-DVI-cable (5m long) to my upscaling DVD-Recorder and, voila, it worked great!
No hassle with H-sync or V-sync, no displaced picture, no problems at all! The picture quality is absolutely perfect, sharp, nothing to complain about! A really great product, THANK YOU guys!” – ottokar1

 

“My second test with the HDfury with a Barco D-cinema DP100 went smooth. No glitch the HDfury just work. Source used was a PS3 with firmware version 1.75 so it’s 1080P60. A brandless 1.5m hdmi to dvi cable was used. The HDfury unit connected direct to the UXGA input of the ACSAR2 unit of the DP100. The projector immediately without fuss load the correct file and image comes up on the 13m wide screen.” – Ciputra (Note: This HDfury is being used in this commercial movie theater!)

 

“I ordered the red version on Sunday evening and we received it Wednesday at around 2 PM. Fastest shipping I’ve ever seen from any vendor outside of Canada, let alone from Taiwan. Remarkable. I must say that the quality of the red cable-adapter itself is first rate. When I took it out of its compartment, I was very impressed with it. Since we received the Fury yesterday, we’ve probably watched a good 8 hours of various HD channels. Some of the “Rick Steves’ Europe” shows have absolutely stunning picture quality, and today we watched a show (whose name I cannot now remember) about jungle bugs. It also had superb color and image quality. These are the sharpest images ever projected from our NEC on our screen. Today we sat just under 80″ from a 92″ diagonal image and it still looked excellent – sharp and free of any artifacts. We took our first mini-vacation today! So far, the HDFury has been a great purchase for me and my wife. I hope it gives us years of service.” – Herve

 

“Got my HDfury a couple of week ago as I figured I should be trying one of these things out myself and see what all the fuss was about. I had heard that using the HDfury produced a better image quality than using component out on source devices such as HD-DVD and Blu-Ray players (not to mention that you can now upscale standard DVD’s too), but I really wasn’t ready for how much better the HDfury made my Blu-Ray movies look! I expected a subtle increase, but was shocked when I was presented with a substantial increase in image quality. I was pessimistic as Blu-Ray discs from my PS3 component output already looked fantastic on my setup so I really didn’t understand how things could look better. I was already using what’s considered the best component to RGB transcoder out there (the RTC2200) as follows: PS3 component out -> RTC2200 component to RGB transcoder -> 25′ RGBHV cable -> Barco Cine8 Onyx projector. Man, was I wrong! Going digital and bypassing what’s likely average quality DACs and op-amps in the PS3 made ALL the difference! The first things I noticed right away was the better dynamic range even just in the PS3 menus: The whites were just a lot tighter/purer/punchier/brighter, the contrast range is better, the colours richer, and the image is actually considerably (not just a little bit) sharper! The difference isn’t subtle: I switched back and forth between the two and it’s like a gray haze was removed when using the HDfury over the HDMI output vs. the component output. Over component the image lacked punch, wasn’t as sharp and was somewhat muted. Using the HDfury also resulted in better small object detail. The smallest details and variances in image detail are now perfectly resolved. I didn’t know what I was missing. I did try 1080p on my projector quite a bit and 1080p is 100% resolved now. No problems at all. 1080p looked fantastic. I had zero problems using the HDfury. Just plugged it in and that’s it. Didn’t even have to do any image shifting on the projector! I should have gotten Franck (of HKmod) to send me one of these sooner. Thanks Franck! Excellent work Jean! The engineering behind this thing is fantastic! Now I see what all the fuss is about!” – Kal (site webmaster)

 

“All I can say is….wow! To everything! I ordered the basic HDFury on 9/25 and it arrived here in beautiful New Hampshire on 9/28. SPEEDY! I seriously thought it wouldn’t be here until next Monday or Tuesday. Now, my system is not the best. I’m using an Epson Powerlite Home 20, which maxes out at 1080i. I’m running the HDFury through a Phillips 6 foot HDMI/DVI cable hooked to a $49 Phillips upscaling dvd player and the results are FANTASTIC!!! I hooked the HDFury up to the VGA input on the projector, instant steady bright blue light, selected 1080i on the player, and I couldn’t be happier! Screen door effect? Yeah, somewhat, but again, I’m projecting old school LCD projector at a bit over 110″. It’s still a noticeable improvement over what I was viewing at 525p. I thought that I might need the power boost from the 5v adapter, but the results I’m getting with just the ‘Fury are fine by me!!! Money, unfortunately, is a concern here, however with the HDFury, I’m looking at a crisp image on a budget projector and all is right in the world Great product! Thanks again!!!” – TJ101

 

“I got my HDFury yesterday and hooked it up…AND IT’S AMAZING! I’m so happy with this product I don’t even know what to say. The picture quality is SO much better than what I had before. I hope anybody that sees this that bought a Protron (37″ LCD) looks seriously at this product. It is the best I could ask for!” – Templar99

 

“I have successfully connected my PS3 Console to my old 32″ Plasma TV set through “HDFury”. In fact, the installation is very simple. Just plug and play and no configuration required. Also, the output picture quality is very satisfactory even though my Plasma TV only support 720p (1280 x 720) picture quality. I can now enjoy HD digital signals on my old analog-based Plasma TV set. Thank you so much for answering & providing me all previous technical questions. The ordering process and delivery service are very excellent and fast. Really a good service. Thanks.” - Eric

 

“Just wanted to make a quick post to let you know that everything is working great! I have a Mits 65″ Diamond, with the best connection being component. It is a 1080i set via the DTV connection which will handle 408i, 480p or 1080i. Within the component connection, you can use component or you can use RGBHV, not both. I hooked the HDMI cable to a new Samsung Duo HD-DVD & BluRay player. Plugged in the Fury to the DVI end and used the Green cable which outputs to BNC. I snapped on 5 rca phono to BNC adapters and plugged it into the RGBHV. Worked immediately and the video is outstanding on HD-DVD, BluRay and it is doing a nice job of upconverting SD dvds. No left shift or anything like that. Thanks for your help here and the Fury HD is a winner IMHO.” – Dave

 

“Got my HD Fury cable. Works great. Everything on the PS3 from the XMB interface to games looks much cleaner than when I was using the VD-Z3 VGA/component converter. My monitor didn’t officially support 1080p, so I had to downscale to 720p. Still, everything looks great, so I’ve got no complaints. Kudos go out to HD Fury for putting out this product. Best of luck.” – Omnimaxus

 

“I want to thank the people at HKmod. I ordered an HDfury Gamer cable so my grandson could play his PS3 on a 7 year old Mitsubishi RPTV. The short time from order to delivery shocked me.“ – Walt

 

“Another thanks to HKmod for the HD Fury, five days to the boonies is pretty good. Hook up is PS3 -> 10′ HDMI to DVI cable -> Fury red edition -> BG808 no adjustment needed (other than figuring out the PS3 setup). Very pleased with the picture.“ – Colin

 

“The HDfury made a night and day difference between my DirecTV HD DVR HR-20 and my Ampro 2300 G projector. I had had good pictures with an RCA DTC HD receiver directly from its RGB outputs, and then with the DirecTV Tivo brand HD DVR through a component to RGB converter. However, when I switched to the MPEG 4 DirecTV HR-20 DVR, the same setup yielded blown out bright areas and generally a truly bad picture. I thought my projector was at fault, and only tried the HDfury because I had read that sometimes the component outputs are not well engineered on recent equipment, as they merely support legacy users like me. At any rate, converting HDMI to RGB worked to solve my problem. I am not sure if the picture is better than with the two previous setups, but it is vastly better than starting with the component outs of the HR 20. Thanks” – Burt

 

“I ordered mine on a Friday, received it Monday or Tuesday. Excellent speed of delivery “ – Disjunto

 

“Well I ordered and received my HDfury Gamer Edition about 2 weeks ago. i ordered it late Wednesday night and it arrived on Monday, not bad at all. I hooked it up to my Viewsonic A90 CRT monitor and my PS3 and it worked right off the bat, running at 480p default. I then went into my PS3 options and changed the resolution: I can now run at 1080i! before the HDfury, i was using the composite video cable connected to a tv… looked like garbage. But now, it looks AMAZING. I finally feel like i got my money’s worth for my PS3, thanks to the HDfury making it look like its supposed to. With such quick shipping, affordable price, and phenomenal picture, I will be recommending the HDfury to everyone i know who is looking for high definition picture without the massive price tag of a new TV. EXCELLENT product!” – S.B.
