It really is best to see a monitor in person if you can.
Wide screen monitors are very good for desktop work.
If they are truly wide like the 49" unit, the curve keeps from having the edges washed out.
One negative for me is the limited height of such units.
If the image quality is tops,you will not have a problem with seeing the edges.
I went from a 40" 4k monitor to a LG 48" OLED TV Image is stunning.
You will need a 3000 series graphics card to get hdmi 2.1 necessary to drive refresh past 60hz.
I found a GTX1080ti able to run FS2020 reasonably well.
The fps was in the 25 range, but that did not seem to be any sort of a problem.
One advantage of a single large monitor is that you can size individual windows as you wish and not have any monitor borders get in the way.
