Getting Started with HDfury4S

No HDMI? No standard HD resolution on your display? No Problem!

Play HDMI movies, games, satellite/cable, and internet videos on any TV/HDTV/Projector or Monitor! HDfury4S allows you to view HDMI content from your PS4, X1, PS3, X360, Blu-ray player, satellite/cable or internet on all standard 50/60Hz or 100/120Hz displays with either Digital or Analog inputs or both at the same time! If your TV, monitor or projector cannot play HDMI content because it lacks of a HDMI input, HDfury4S can help you to achieve upscale/downscale, scanconvert, transcode and conversion to match any HDMI/DVI-D/YUV(component) or RGBHV(VGA) display's native resolution! If your TV, monitor or projector can play regular HDMI games and Blu-ray movies then the HDfury4S can still help you to achieve upscale/downscale to match your display native resolution! Upgrade to Perfect HDMI at your display native resolution for a fraction of the cost of buying a new display! The HDfury4S supports every HDMI signal type in existence today from SD to Full HD and beyond (up to 1080p96). It is firmware upgradable so that new features can be added in the future as needed! In addition to supporting all standard displays in either analog or digital (HDMI, DVI-D, RGBHV, component), the HDfury4S also offer dedicated and convenient firmware to 1080i sets like the fantastic 1080i Mits RPTV or the Pioneer Kuros and PDP line of Plasma. How difficult is it to set up? A few dip switchs on the HDfury4S must be set once depending on whether your TV is a 50/60Hz or 100/120Hz model or if it takes Digital DVI-D/HDMI or either RGBHV or component as input. No other setup is required. For more information download the User Manual from the Download Tab above. HDfury4S is 100% plug-n-play with existing convenience scaling for 1080i max display (others doable on request) Just connect the HDfury4S between the source and the TV/projector. That’s it! Which projectors and TVs are supported? Any standard 50/60Hz or 100/120Hz displays will work with HDfury4S. HDfury4S is the world first solution that work with any Digital (DVI-D/HDMI) or Analog (RGBHV/component) displays, no matter if they are 60hz only and you live in a 50hz area or if they don't support any standard HD resolution like 1920x1080 or 1280x720. Thanx to the embedded scaler and unique aspect ratio modes, you will be able to display HDMI sources at the best of your display's capabilities ALWAYS & GUARANTEED!

Got questions ? We have answers !

My display is not 16:9, how doe the aspect ratio modes work ?

99% of the time any scaler or TV simply stretches the picture to fill the screen or then leaves black bars on left/rigth because it assumes fixed 4/3 aspect ratio on a 16/9 screen. Instead the furyscaler will actually retains 100% the exact correct input aspect ratio and "drops" it on the final output frame size while scaling the maximum side. Therefore it automatically leaves black bars on top/bottom or sides as dependent on the incoming resolution.

I have a PC mode on my TV (or a PC monitor) what resolutions are supported for graphics mode ?

All following PC graphics mode are supported in either 50 or 60Hz: 800x600, 1024x768, 1280x768, 1360x768, 1440x900, 1600x900, 1280x1024, 1400x1050, 1600x1200, 1920x1200. More supported resolutions can be added on request.

What output resolution does the HDfury4S support in HDTV mode ?

All known SD, HD and Full HD formats are supported including: 480p50, 480p60, 576p50, 576p60, 720p50, 720p60, 720p100, 720p120, 1080i25, 1080i30, 1080p24, 1080p25, 1080p30, 1080p48, 1080p50, 1080p60, 1080p72, 1080p75, 1080p96

My HD display is from Europe/UK/Australia where we use a 50Hz refresh rate. Will it work?

Yes, as all HD displays that support 50Hz also support 60Hz. Additionally HDfury4S is capable of toggling 50/60hz for PAL/NTSC in both HDTV and graphics modes at will.

My HD display only accept 60Hz material and in Europe/UK/Australia, we use a 50Hz refresh rate. Will it work?

Yes, through a simple dip switch setting, you can force the output to be always 50Hz if needed.

What version of HDMI does the HDfury4S work with? Do I need HDMI 1.3/1.4a? Does it matter?

It does not matter. HDfury4S works with any version of HDMI from 1.0 and up.

Do I need to set anything special in my HDMI source device to set resolution correctly?

No. The HDfury4S will be detected as 1080p capable by your source and always accept and process the highest quality stream from your source devices. There is no need to set the HDMI source to any specific resolution, the HDfury4S will take care of it and scale up or down if needed.

Is there any latency (delay) introduced to the signal?

Less than one frame of latency per second is added to the signal which is not at all noticeable in games.

What is the USB port for?

To supply power from any USB port available if required (such as a PS3 USB port) and for firmware upgrades when new (additional) functions and enhancements are offered.

What about long HDMI cable runs? Can I expect issues?

HDfury4S acts as an HDMI repeater device. So having a HDfury4S in the path will amplify and recover the signal. You should not need any passive (or active) HDMI amplifiers, especially if you put HDfury4S in the middle of your cable run. If you previously had to use an amplifier, the HDfury4S can most likely take its place. The HDfury4S has been used with 50 foot (and longer) HDMI cables without issues.

How are the new lossless audio formats via HDMI input handled ? E.g. DTS-HD/MA and DD/E-AC3 : Are they stripped down to DTS core or Dolby Digital respectively to fit the requirements of the S/PDIF standard ?

Lossless audio is transmit through HDMI output only. HDfury4S does not compress or otherwise create loss to the incoming audio. Only stereo and 5.1 sound can be output via SPDIF output and analog output.
