Running a large resolution causes the resolution to show up incorrectly when revisiting settings menu

I have a 1920x1200 Samsung display, and I noticed that if I run the game in 1680x1050 or lower, it works correctly. But if I run 1920x1080, quit out of the game, relaunch the game, and go into the settings menu, it shows up as 1823x1080 (the x dimension is reduced). Similarly, if I run 1920x1200 (native res), quit out, and relaunch, settings shows that res as 1823x1139 (both dimensions are reduced).
