Distorted Imaging in faces

I’m designing a factory and have inset a window graphics into a faces.


No matter what I try, only UV and flat gets even closer. I am a beginner here and any advice would be welcome.
Thanks

probably cause of the way you UV mapped it.

adding some subdivisions is the lazy way to fix the problem.

if you wish to fix it the proper way, then show us hte UV map.

SORTED.
I used the UV method and worked it that way.
Thanks for the advice.
