Can LP support 1920x1200 resolution?

Hi guys, I re-entry purchased a 10" hdmi screen that had 1920x1200 resolution. I got the screen working on a raspberry pi after some fiddling with the config.txt file. But I'm having trouble getting the LP to output at this resolution. i tried adding a custom resolution in the display properties but it doesn't let me add this particular size. Did anyone know how to accomplish this?
