LG 37lf65 - no signal problem with PC

[misko2]

i ve got my pc connected to this lcd with dvi-to-hdmi cable but i can only see picture when i first turn on tv than pc!
If I change source after that there is message no signal!?
Anyone have an idea what is the problem

I also have annoying bleeding, anyone tried to replace unit and what was the answer.

And final question; how many bad pixels LG tolerate ?

Thx for answers and sorry for my bad english
Regards

What res have you got the PC set to?
Try setting to 800x600 @60 Hz to start with, connect to the TV. Once you establish a picture raise to the LCD's res.
If this fails you may need to switch of the Display properties on the grahpics software, known as the EDID.
If you are using a ATI graphics card then make sure you are running the latest version of catalyst. Same goes for NVidia.
What graphics card do you use or motherboard? Make model?

I, ve tried all resolutions and nothing works.
Btw i have a gigabyte GA-MA78GM-S2H with onboard hd3200.
Ive tried with the latest drivers but CCC says that are not compatibile with that drivers.
I didnt found how to turn off edid.
Will try omega drivers.
i will post results
