A75m-UD2H (Bios F4) Black screen if boot with monitor off
« on: November 01, 2011, 11:33:24 am »
Hi, i have a plasma LG 50PC55 connected by HDMI (with DVI is the same).
If when i boot the PC, the Tv is OFF, when i turn on the TV there is no signal, i must reboot the PC with the TV on.
Some times the TV is ON but the PC do not send signal to it when it boot and i must restart the PC.

I'd like to have in BIOS the option to select the default output (HDMI, DVI, VGA, DisplayPort) to permit boot with monitor off.
Is there a way to enable HDMI output after boot?

Thanks.

That is usually controlled by your video card if you are using onboard graphics you can tell it to boot using the onboard. I know amd/ ati cards if you use a tv it wont detect it if you turn tv on after the pc. Unless you use a regualr monitor and open CCC and tell it to manually detect. Otherwise turn on tv and then puter.

I'am using onboard graphics and the bios option is "onboard".

I'd like to have the option to force output to HDMI, so it will work if i boot with TV off.

Thanks

Until someone comes and tells you differently id say email support and ask if they are planning a newer bios with that option otherwise you might be out of luck on the current bios. Maybe there might be a windows program that would help you but that poses it own set of problems.
