Referene 5770 (i.e. 2xDVI) problems with HDMI display

[rtbas]

I recently installed a Radeon 5770 made by HIS. I had installed Kabyl's boot loader and my 20" monitor works fine on either of the DVI ports. However, my HDMI television is not detected in OS X (it does work during POST, though). System Profiler lists all of the display ports, it just never recognizes that the television is connected. I know people who have a card with 1xDVI have problems like this, but mine has 2xDVI so I expected it to work without any trouble. I can't find anyone else with this issue, so any help I can get would be greatly appreciated.

 

My system components are:

 

Intel Q9450

Gigabyte GAEP35-DS3L

8Gb RAM (I don't remember the manufacturer)

HIS HD 5770 (Newegg: HIS HD 5770)

 

The output of lspci -nnvd 0x1002: | grep -B2 Subsystem is:

01:00.0 VGA compatible controller [0300]: ATI Technologies Inc Unknown device [1002:68b8] (prog-if 00 [VGA controller])

My boot.plist file looks like:

<?xml version="1.0" encoding="UTF-8"?>

I have attached a screenshot of the graphics tab of System Profiler, an IOreg dump (switch the file extension back to .ioreg) and my dsdt.dsl (switch the file extension by to dsl).

 

 

Sorry, I forgot to mention that I'm running 10.6.6 with a patched AppleHDA.

I am having the exact same issue. I have managed to get my TV to mirror my desktop somehow, but it doesn't not detect that the TV is connected. Does anyone have any idea what could be going on? Any help would be greatly appreciated.
