looselycoupled

Hello! We are working on a 32" RRM and a 43" Monster Arcade 4 Player DIY kit for a break room. They will be mostly running MAME. I'm trying to figure out if there are popular/recommended monitors in these sizes that people are using. 1) G-sync/Freesync definitely seems worth it (admittedly may be tough in the larger one). 2) Probably looking for 1440P for the 32" and 4K for the 43", want to run scanline HLSL shaders. 3) Regarding the wide 4 player unit, do VA displays generally have a decent viewing angle? or better to go with IPS displays for 4 player cabs? I've been looking around r/cade r/mame, forums, display lag, display Ninja, etc, but I can't really find a consensus or a good list of recommended displays. Thanks for any advice!
