Hi everyone, I have my pc connected to a 40" TV both by HDMI and VGA (video card outputs not motheboard), but if I try to enter the bios settings (or windows start up settings) from HDMI I have to change the source to VGA, I cant see those 2 options through HDMI; any settings I could change in my motherboard Bios in this effect.

By the way my motherboard is a ASUS Z97-A and my Video Card is a GTX 660 TI, any suggestions?

thanks in advance

Many TVs seem to be limited to only a few resolutions through HDMI but more through VGA. I'd guess your BIOS is choosing a resolution that VGA supports and HDMI doesn't.

I'll also guess there's no BIOS option to select setup screen resolution. Assuming you don't need to mess with BIOS often, the workaround would be to switch to the TV's VGA input when you want to change something and switch back to HDMI for everything else. Maybe someone else has a better idea...

It's the I/0 system which is confused by the fact that both VGA & HDMI cables are connected at the same time.
Disconnect the VGA cable from the card and you should be able to see the BIOS & Boot settings through HDMI.

Thanks Norsestar, thats what I usually do, the problem lies when my wife is using the computer, who is not computer savy, whenever something happens and windows doesn't shut down properly, when it restarts it goes to recovery mode, and she doesnt know about chaning source to VGA and avoiding windows go to recovery mode, I've tried explaining her on multiple occasions and she doesn't get it, so I thought the solution would be for he to choose to start windows normaly and avoid that.
