Limiting Resolution Support (EDID modification)
Can I limit the maximum output resolution that my HDfury2 supports? For
example, 1080i instead of 1080p?
Yes. The HDfury2 EDID may be reprogrammed to remove support for certain
resolutions if required. This is an feature reserved for advanced technical users.
Do I need to limit the maximum output resolution that my HDfury2 supports?
Usually not. If your display supports 1080i but not 1080p simply set your source device
to the maximum resolution that your display supports. In other words, if your display
supports 1080i but not 1080p, in your source set up menus choose 1080i or uncheck
1080p from the list of supported resolutions.
So why would I want to limit the HDfury2 resolution?
Two reasons:
(1) Some source devices (such as some Samsung Blu-ray players) auto-detect the
maximum resolution that the display can support every time the player is turned on and
reset their resolution to that maximum. The source "sees" the 1080p capable HDfury2
and therefore sets its resolution to 1080p, requiring you to manually change the
resolution every time you want to use that source if your TV doesn't support 1080p.
Very annoying!
(2) Some displays may run hot or even malfunction if feed a resolution that is too high
such as 1080p. If you know your display doesn't like 1080p, turning it off in the HDfury2
adds some piece of mind and assurance that you'll never accidentally feed it too high a
resolution.
Power
Do I need to use the HDfury2 power supply?
The HDfury2 power supply is required in most setups. Some source devices will,
however, provide enough power to the HDfury2 over the HDMI line for it to operate
properly. Most source devices do not. We recommend that the power supply be used at
all times.
Why don't all HDMI source devices provide enough power to run the HDfury2
properly?
At maximum resolution (1080p/60Hz) the HDFury2 requires 370mA of current to
function correctly (more if the GammaX is also used in conjunction with the HDfury2).
The HDfury2 can be powered by the HDMI cable, however the HDMI standard states
that it HDMI should provide 'at least 50mA and at max 500mA'. This means the
manufacturers are not required to provide more than 50mA of current on their HDMI
outputs which is not enough to power the HDfury2. Less current means cheaper
manufacturing costs which means that 99% of manufacturers opt to just meet the
requirement of 50mA. Therefore most sources are close to the lower end at 50mA and
very few are near the upper end at 500mA. The PS3 and Xbox360 are the only two
notable exceptions. We recommend that the HDfury2 power supply be used in all
