View Full Version : PB287Q + ROG Maximus VIII Hero Display Port 1.2 On Boot

Fo some reason my PB287Q 4K monitor will not display the boot screen.

It remains black without power until it gets into the OS (Win10), at which point it seems that it switches to DP 1.2

How do I set it up so I can use this monitor to get into my Maximus VIII Hero BIOS?

As it is now I have to use another monitor using DVI to do what I need to do.

Which graphics card are you plugging the monitor into? The 1080 or 980? I'm guessing the GTX 1080, I'm guessing it's likely a display bug. Maybe you can turn off all quick boot options in BIOS to see if that fixes the issue for you.

Also I think it's because your system is probably booting so fast that your monitor doesn't even have a chance to detect the DP signal before it loads the OS.

If you keep hitting DEL on your keyboard does BIOS screen ever pop up? Maybe you can use different display connection first to change some settings in BIOS and try again.
