I have a computer with 3 monitors. The main monitor is a 49" Samsung set to 5,120 x 1,440 resolution. The two other monitors are very old and have low resolutions and I don't use them except to reference periodically. The monitor I'm viewing it on is a 43" with 3840 x 2160 resolution.
When I log into TeamViewer I'm only offered the two old monitors which have a max resolution of 1920 x 1080 (also it changes the orientation, but that's a different problem). This isn't big enough to be helpful.
How do I use the 49" widescreen or at least have a greater resolution on the screens that are offered?
