hello, i need my PC to show Dos and bios on my HDTV.
at the moment i can only see the display after windows screen up.
i use only 1 screen-my HDTV.
my PC connected to the HDTV with HDMI to HDMI cable.
sometimes when i booting it i can see only a black screen("No Signal" message for ever, i guess that is due to static electricity), and nothing apear's on the screen.
then i need to shut down the PC, unplug the supply, hit power button for 20sec or so, then reboot the PC and plug regular PC Monitor screen, to see whats apear's on dos/bios for boot my PC again.
then after windows go up-i can swap the display back to my HDTV.
if i wont swap the screen(remains all the time with the HDTV screen) the PC remains on a black screen for ever, the HDTV inputs "No Signal" message.
this is my questions:
why cant i see dos on the HDTV?
what can i do to see it?
how can i solve the static energy problems?
thanks for help
