In Windows I have set my PC monitor to be my primary monitor. But when I boot the computer, bios / GTX 650 thinks that my TV (connected via HDMI) is the primary one. So, if I want to enter the bios for example, I have to check it out with my HDTV. PC monitor is connected via DVI-D. Where can change the priority of monitors before the system has loaded Windows? Or is there anything that can be done? Motherboard is M5A97 EVO R2.0 and it has UEFI bios. I have cloned my desktop to both screens. When I set the GTX 650 to output 1080p 50hz, video playback has tearing in my HDTV but in the PC monitor it's fine. Is this problem due to fact that the PC monitor doesn't support 1080p 50hz and GTX 650 is forced to output 1080p 60hz and that my HDTV doesn't sync that (it still recognizes the signal as 50 hz). 60 hz is fine.
