No splash screen and no bios on GTI13 with Thunderbolt

SiggiUA

Hello,
On my brand new GIT13 I don’t see the splash screen and I also don’t see the bios screen. The monitor remains blank and even goes to stand by. My monitor is a DELL U4021QW (5120×2160 resolution) and connected via Thunderbolt. A picture is displayed only in Windows.

If I use another monitor which I connect via HDMI, everything works as expected.

Is there a fix for this behavior with Thunderbolt?

Hi there,

It might be compatiblity issue with your monitor.
Here are possible solutions:
①Temporarily connect an HDMI monitor to access BIOS.
Look for display settings (CSM, UEFI resolution, or Thunderbolt pre-boot support).
If available, set the boot resolution to 1080p or enable CSM (Compatibility Support Module).
②Please try another thunderbolt cable.
