Built my new system today and started getting a couple of boot issues when using displayport.
Firstly, I can't access bios via displayport. The bios screen appears (although the resolution is out as it cuts the edges off the text at each end of the screen), and when I hit del, I just get a black screen and a cursor. Then the computer might reboot itself or just hangs on the black screen.
Secondly, with displayport connected, if I don't enter bios by hitting del and wait for the OS to load, it shuts itself down just after the bios screen. It then restarts, and does the same thing again. It might boot through to windows on the third try, or it might just give me a permanent blank screen and I have to reset.
Everything works fine if I use HDMI. I can access bios and shutdowns/reboots go without a hitch.
I have a Dell U2414h Ultrasharp monitor. Radeon r9 280 gfx and a gigabyte z97 motherboard. I've read about some other people having boot issues with displayport and they seem to often be with dell monitors. Anyone have any ideas? Is this a common problem with DP?
Edit to add, I can get it to do a shutdown reboot with DP connected no problem, its just whenever I try to access bios it starts doing all the above.
