HD 6850 :- No complete boot when hdmi plugged in
Jun 28, 2011, 9:18 AM
I have AMD Radeon HD 6850 and using only hdmi-hdmi cable.
With hdmi attached and pc turned on, the hdtv shows no signal but the power LED is on for 10-15 seconds then goes off for about 2 seconds and then restarts and follws the same.
With no hdmi attached and pc turned on, after waiting to boot completely and then re-plugging hdmi i am able to get signal. I directly saw dektop screen on my hdtv. Then pc works fine with no problem.
Even if i restart it from desktop it works fine until shutdown but no signal and power led blinking after that.
I also updated CCC but during installation tv went to no signal. I finally had to turn off main supply. After struggling on pc to turn on, i saw CCC was updated.
Also i am not able to enter the bios.
Please help to solve this problem.
I dont want this struggle any more.
Thanx in ADVANCE

1) => Yes.......with hdmi i couldn't enter bios while dvi to vga works fine and can enter in bios also.
I think bios does not detect the tv and sends no signal.
But in windows CCC detects the tv and sends the signal.
2) => My LG 32PC5RV doesn't have dvi input, only vga and hdmi.
3) => I have only one such tv with hdmi input.
I want to use hdmi for better video quality than vga.
Please HELP !!!!

I came to know that my LG 32PC5RV does not support DVI-PC. It only supports RGB-PC. (From User's Manual)
But via hdmi, it plays good video with 720p.
Is there a way so that it support hdmi-pc (or dvi-pc) fully ?

Is there any way that:
1) Start PC without bios
2) Stop bios detecting the display settings
When i simultaneously connect vga + hdmi, there is also the same problem.
But by removing hdmi i came to know that bios says "There was posting problem press Y to enter setup or N to start with previos settings "
This can solve my problem, please help !!
