Question Sim-Racing with a cheap curved monitor ?

[4711Austria]

Hello!
I will do racing with VR, but some or often via Monitor.
Thinking of a cheap curved (34"?) with the option to use 3 of them later on.
Must have a VESA mounting to get directly mounted to the rig.
I do not know what specs I have to look for.
Hopefully you can tell me what are the spec I have to look at.
