Radeon VII 21:9 monitor no uefi bios

Question asked by metuz on Jun 10, 2019

Hey

 

I can't enter bios with my Radeon VII if I use my 21:9 LG monitor (3840x1600), if I connect an old monitor I'm able to get into BIOS. If I use an old GeForce 970 or Vega 64 I don't have any issues.

It not just that it can't display the bios, but it completely ignore Delete press in boot process and go into Windows.

 

I have updated the vBios using ADVANCED MICRO DEVICES, INC. VBIOS END USER SOFTWARE LICENSE AGREEMENT (OBJECT CODE ONLY) | AMD but din't change anything.

016.004.000.030.011639 to 016.004.000.038.011717
