Window 10 Boot logo has wrong proportion

[Snowline]

I got problem since I buy this cpu. It has wrong size of window logo when boot. But everything work fine just want to know how to change to correct proportion.

it looks normal to me, what size do you think it should be? Size depends on the monitor resolution

its look wider than it should be. It seems like no driver when boot.
it should look same as picture you posted.
Also I used dell u2414h monitor before. It didn't look wide.
This one that I got problem is also u2414h

You can see download circle look more stretch

yes, no drivers at that stage. I wonder if its a bios setting, what motherboard do you have? Might want to look in manual and see. Are you using hdmi or Display Port

I assume windows looks fine? wonder if its the OSD on the monitor

only similar case I found was on a 2560x1440 screen, yours is 1080p so should show right

well, Full screen logo show is just the bios flash screen, so I doubt its that.

On the chipset tab, is Internal graphics enabled? (thats the default setting, it turns on the onboard GPU)

Did you fresh install or something? what changes did you make? Seems odd it worked with same monitor before but not now. Wonder if its a setting on the display itself, do you still have that other screen - have you tried it?
