I have a curved monitor (38"), bought it for MSFS 2020, which I didn't like, so went back to FS9 and FSX and wished that I had never sold my old flat 23" monitor. I fly FS9, FSX, CFS2 etc. in a 23" screen on my 38" monitor with big black "panels" on both side. And for ME it still feels different from the "old" flying on the 23" flat monitor.
So MY advice: don't buy it.
