Mac mini M4 Pro Display Resolutions

I have a MacBook Pro M1, and a 5k LG monitor with 5120 x 2160 res. When I use it I can use the "default" setting which is 3840 x 1620 and it is perfect for me.

I just got a new Mac mini M4 pro. Its default for the same monitor is 3360 x 1418, and the resolution kinda sucks. But there is only one high res option at 5120 x 2160 which is way too small to see things.

Is there a way around this that I am not aware of? would the same issue be on the studio? I do not understand where the limitation comes from unless it has something to do with the MacBook Pro m1 having a certain res on the built in display. But that would make me think the mini should be able to do that res no matter what because there is no built in display.

both are using same thunderbolt cable.

Also both are using same OS version.

here is the options :
