Hi,
My graphics card is ATI Radeon HD5470. I get resolution of 1366 x 768 after Internal LCD forced EDID. I've a Samsung TV to which I want to connect using HDMI cable. I do it without any problem in Win 7, however, could not do it using Mountain Lion 10.8.1

Has anybody succeed doing it? Let us share.

p.s. I used a EDID extractor software to extract EDID in Win 7 while TV connected through HDMI cable and I can see it extracted a separate EDID for my Samsung TV. So, like Windows, can we have multiple EDID for multiple device or TV in this case?

I'll try. currently, I'm using Hoolock and when connected to TV via HDMI cable, I get distorted display in my computer screen and my TV could not find signal. Let see what happens using Langur.

i use an hd5450 hdmi to tv...works fine, using GraphicsEnabler=No (gives me default framebuffer, ATY,RadeonFramebuffer)
Attached File  Tv on HDMI.png   93.95KB   23 downloads Attached File  IOregistry, ATY,RadeonFramebuffer.png   144.05KB   22 downloads
...i'm in the process of editing framebuffer personality, to get a match for my card outputs, as the hdmi outputs differ on my card from apple's...meanwhile this works for now as my sole display...
...the only personalities i see in the 5000 controller that include an hdmi port(stock) are Uakari, Baboon, Vervet and Eulemur

I tried like you said but just desktop background came into my tv. my tv has resolution of 1280 x 720 whereas my laptop has 1366 x 768. I succeed making a folder in a desktop but the folder wouldn't open. It seemed like those icons were stretched beyond the reach of mouse! I tried to change the aspect ration of tv but to no help. I will also try robertx method. let see. btw, have you tried the method you said to me.
p.s. btw, my laptop screen was black when it was connected to tv via HDMI.

I tried it with GE=No. It successfully worked but the problem was I only got resolution of 800 x 600 with 1 mb of video memory. Apparently, I have Internal LCD forced EDID display otherwise I wont get reolution of 1366 x 768 or my card isnt recognised.

Artur-pt's idea is also working except icons arent visible (using framebuffer Langur). I think the problem is due to my resolution 1366 x 768 whereas my TV has resolution of 1280x720. May be I need to change the resolution of my computer to TV's before using HDMI to connect to TV.

Check the third pic, I mange to boot using AtiConfig=Langur to TV but no menu icons appear in the desktop. However, I managed to move my mouse out of visible desktop area and drag that 'Scroll Reverser' file to visible desktop area. looks like resolution issue.

...i guess my way isn't a go for you...apparently you require the GraphicsEnabler=Yes, as i see in the pics you don't have hardware acceleration(i'm on a desktop box... so no internal monitor to muddy things up...)sorry :angel_not:
