Getting Started

Is HDfury compatible with my Display ? (How to make sure that your display is compatible)

If you are not sure whether or not HDfury is compatible with your PC Monitor, CRT Projector, or Plasma/LCD HDTVs we recommend you to perform the following test:

720p TEST
– Setup a PC computer graphic card to 1280×720 resolution through its VGA output in order to see if it displays correctly on your screen through the VGA input (SUB-D HD15/5xBNC/DB9)
If you can see the output it means that you will be able to display 720p from any HDMI or DVI(HDCP) source on your screen using HDfury

1080p TEST
– Setup a PC computer graphic card to 1920×1080 resolution through its VGA output in order to see if it displayed correctly on your screen through its VGA input (SUB-D HD15/5xBNC/DB9)
If you can see the output it means that you will be able to display 1080p from any HDMI or DVI(HDCP) source on your screen using HDfury

It has been reported that even though some PC monitors allow higher resolutions to be displayed such as 1920×1200 it does not automatically mean that the display supports a 1920×1080 resolution.
As an example both Dell 2405FPW and Sony P234B are listed as 1920×1200 native resolution. Unfortunately the Dell one does not support a 1920×1080 resolution correctly while the Sony one will display it perfectly.
So once again, performing the above test will allow to find out if HDMI 720p or 1080p could be displayed on your screen with HDfury.
We believe that the EDID of any 1920×1200 monitor could be updated in order to support 1920×1080 resolution. More on that later.

Plasma and LCD HDTVs are oftenly listed as “Supporting 720p/1080i” or “720p/1080i compatible”.
This does not mean that these displays are TECHNICALLY ABLE to handle 1280×720 or 1920×1080 resolution !
In fact most of them are 1024×768 max resolution
Basically those displays will receive a higher resolution signal through their components or VGA input and DOWNSCALE it to 1024×768 (the best supported resolution)
The well designed (often more expensive) displays will DOWNSCALE 1280×720 or 1920×1080 through both VGA and/or component input. (Ex: Panasonic TH-42PH9WK)
However it has been reported that some do not DOWNSCALE signals sent through the VGA input but only through component !
Therefore it is best to use the above test to make sure that the HDfury will work with your display device !

Is HDfury compatible with my Source ?

HDfury is FULLY compatible with all recent source devices such as the PS4, Xbox One, Roku, Tivo, Apple devices, PS3, X360 Elite, HD-DVD players, Blu-Ray players, HDMI graphics card and the latest set-top-boxes (STB) and DVD players with HDMI outputs. A power supply might be required for some sources.

Some older STB and DVD players with HDMI output may have potential problems due to the following issues:

– HDCP Handshake issue (HDCP not correctly implemented by the Source Manufacturer)
Some older STB and DVD players were released before the HDCP specs was finalized, and therefore may suffer from the HDCP handshake bug.
The industry initially announced only one HDCP handshake at power up while on the actual devices and chipsets produced, this HDCP handshake has to be renewed continuously every 2 seconds.
This issue is greatly explained by HDMI.org themselves here :http://www.hdmi.org/training/player01.html (Click on Common Installation Issues and the 2 links above)
As explained by HDMI.org thes source devices will never be able to display any signal on even the newest HDMI displays. These source devices require a firmware upgrade.

Digital and Analog Link between HDMI Source >[DIGITAL]> HDFury >[ANALOG]> Display

You should ALWAYS use the supplied breakout (extender) cable that shipped with your HDfury: No warranty on the quality can be given when using another breakout cable, especially cables that are longer.

My display technically supports 1280×720 (and/or 1920×1080) through its VGA input (RGBHW either 5xBNC/Sub-D HD15/DB9) and I’m using a recent HDMI source. Unfortunately I have no picture on the screen.

Once you hooked up HDfury to your display and ran a HDMI cable to your source the first thing you need to check is the Green led status: Is the Green LED ON ?

The led indicates that HDfury is receiving enough power from the DVI/HDMI source and ensures that device is now operating and outputting an RGB signal.
If LED is OFF, the HDfury is not working, and therefore no RGB signal is going out to your display.
Reasons could be one of the following:

– Your HDMI source is not set to output through HDMI > (ex: on PS3 you must activate HDMI from the display settings)
– The DVI or HDMI cable is using thin gauge copper wires and its length exceeds 5 meters
– The DVI or HDMI source is unable to deliver the 0.5A maximum current over its HDMI or DVI pin #14.

SOLUTION: We recommend you use our USB to Mini USB +5v cable or any +5v power supply compliant to the following:

– Provides REGULATED (+/- 5%) 5VDC power with 0.5A max DC current.

Some notes on when you first connect the HDfury !

When you connect the HDfury for the first time you may see the screen shifted to the left > This is normal.
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.

Enjoy ! Good times ^_^


Why do I need GammaX?

On most TVs and projectors movies and games are too dark or missing detail in dark scenes. GammaX fixes this by adding a ‘Gamma Boost’ without washing out the picture.
Simply plug the GammaX directly into the HDfury2, HDfury, HDfury Gamer Edition, or any device with RGB output and enjoy a more vibrant picture with perfect shadow details!
Using the original HDfury or HDfury Gamer Edition? The GammaX also includes a cable driver which lets you use monitor cables or long RGB projector cables (any length) without having to plug the HDfury or HDfury Gamer Edition directly into your TV!
The included power supply is not needed when the GammaX is used with the HDfury2, simplifying the cables and connections. (The power supply is needed for HDfury, HDfury Gamer Edition, or other RGB source users).
Many projectors and displays only work with either positive or negative sync RGB signals. The GammaX provides a user selectable positive or negative sync switch for displays that only accept negative sync such as the following projectors: Barco 800/801/808/1208, Dwin 500/700, and so on.
The GammaX is 100% Plug-and-play. No configuration or extra steps required. GammaX works at all resolutions, including 1080p and beyond.
Note: GammaX does not support component signals, only RGB. This includes the HDfury2 set to component (YUV) output mode.

Why does Gamma X works?

In most displays shadow detail is severely limited or completely missing. When there are a lot of dark areas in the picture they simply appear as a uniform black area even though the original content has a lot of detail. This phenomenon is next to impossible to compensate for by conventional means such as increasing brightness as true blacks start looking grey and the overall picture becomes washed-out.
GammaX selectively addresses only the correct black information of interest (the shadow detail) to create a very dynamic looking picture with rich shadow detail. The level of correction is adjustable for maximum detail for your particular display.

The following pictures show GammaX in action:

    The Nano is simply awesome. Can now also run the PS4 on a VGA CRT with this device, way better than the PlasmaHDTV I’ve been using. When the device needs to decript HDMI signals, it needs the cord for USB power. My little CRT can do 720p60Hz, and the tiny amount of super-sampling from the PS4’s downscaler in combination with the CRT scanline bloom, low latency, and low persistance creates an awesome visual.

    I just wanted to post that I received my Nano yesterday, which was very quick, and it works as advertised.
    I needed a simple solution to attach my AppleTV v3 to a LG Plasma TV that has lost the use of all it’s HDMI ports. I just plugged the Nano into the TV’s VGA port and it worked.

    The Nano is a LIFESAVER. It works entirely as it said it would. I bought it to connect my PS4 to an VGA monitor because the cheap connectors do not work and it completely pulled through. Although I was on the fence with buying it, the purchase was definitely worth it. Another great feature is the Gamma X. There is a slider on the side of the nano, much like a volume slider, that adds or removes additional brightness as you please, which definitely came in handy. Overall, I rate this device an 10/10 and highly recommend it for any HDMI to VGA connection.

    I have this hooked up to my viewsonic a90f+ crt monitor and after calibration it looks reaally good. Sometimes my family walks past and stop and say “damn…”! The gamma x is a great feature, the audio is great however it would be nice if it could have been vompatible as a spdif/analog audio out so you could have the option of optical audio as well
