Current recommendations for G-Sync/Freesync LCD displays

[winterspan]

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!

Just remember, these are very old games. Freesync is useful to sync to non standard refresh rates like 57.5Hz, but anything over 75Hz won't ever be used.

In my personal opinion, any of the non-TN displays will be good enough for most people. Get the cheapest ips/va display with <75Hz freesync above 1080P.

Over here in europe, the AOC Q3279VWFD8 is the cheapest one that fits the bill. I own it and am satisfied.
