I wasn’t able to find an oled smaller than 55 inches. Even high level led’s don’t start till 55 inches. The best I could find in your size requirements is the Samsung QN49Q70R. Let me run this buy you they make Omni mounts that lets you pull the tv off the wall up to 20 inches in different directions. So even though it overlaps the window you can pull it off the wall a good bit to compensate for the window overlap.
