Unturned with a second monitor resolution glitch

Recently I got a second monitor, it is an old TV with a recommended resolution of 1280 x 720 and 720 x 1280 , my main monitor has a recommended resolution of 1920 x 1080, when my second monitor is plugged in, even if unturned is on the main monitor I can only go to resolutions up to 720 x 1280, Without the second monitor plugged in Unturned runs normally.

Edit: After testing rust with the second monitor on, there my main monitor resolution is missing too, maybe it is a problem with unity?
