BOIS screen mode clipped in my HDMI Display 1x x86 board

When i power up and go yo the bios screen the left and right side of the screen are cliped by about ten characters no settings on the TV have corrected for this but once windows 10 was running the display showed border to border with no clipping

It makes it nearly impossible to use the bios

Is the windows system used supplied by us?

Can you provide some pictures?

this does a good job showing what its doing… this is in the cmos setup screen so no image at all installed this is with the blank hard drive and and just entering setup

i can not gt it to display the full screen in this mode but once windows is loaded it does fine…

I think its probably the screen.

If others are having this problem, I hope to get feedback here as well.
