I just picked up a 4K display for my Sei8 8279U. I plugged it in and when it starts up, the load screen is in 4K. But when windows 11 loads it is in 1080p. When I go into settings the option to change it to 4k is not there.

I have tried several HDMI cords (I used the new one that came with the display first)
The picture looks great! But it isn't in 4k. And I cant find out what I am missing to get it to let me change it.

Any one have any direction?

After quite a bit of searching and reading. I was able to find out what the issue was.

At some point someone made changes to the bios (wasn't me, I bought it gently used). And what ever those changes were it royally messed up the video on the SEi8. Not only was the 4K not working. I also ended up finding out that the second HDMI port was not functioning as well. That turned me in to different direction of searching. Eventually I ended up hitting on the suggestion of setting the bios to optimized defaults.

Set it... Started up..
Both ports work and 4k is functional!!!

So if someone else has the same issue. Consider loading the optimized defaults in the bios!
