GideonGrey, the problem seems to be due to MWO trying to fit stuff into a widescreen 16:9 resolution, by resizing stuff up on low resolution using the height as a base, then multiplying by 16/9 for the width. In your case it's trying to multiply 768 into 1365, and since that can't fit completely it cuts off slightly on the right.
I don't know if your laptop can show 1024 x 576; mine can't since widescreen resolutions don't go that low. Other widescreen resolutions are: 1280 x 720, 1366 x 768, 1600 x 900 and so on.
If standard screen 4:3 needs to be shown completely in 16:9 ratio, MWO needs to have some black space on the top and bottom of the screen to fill up the remaining unused area, like an old film reel. To do that, the video code needs to be tweaked to use width as a base, then resizing by multiplying with 9/16 to get the height, then displaying at the center (black area will be at the bottom if display is set to begin from top left). I'm no programmer myself so I dont know how to do that in the source code. Sorry. :S
