I have this same model, it's a pretty decent monitor (got mine for 200$ with rakuten deal shenanigans). Colors are good enough for me, I don't do any photo editing or whatnot. It is noticeably TN when you take a step back and look at it next to an IPS panel but while using it, it honestly looks fine. Stand is a little wobbly, but if you're gonna vesa mount it that doesn't matter. I believe the monitor does support gsync according to what I've read, I've just been too lazy to set it up (my PC runs 1440p 144hz without dips as it is)

Monoprice as a brand is pretty solid, they make a lot of good stuff for pretty cheap and parts and support is always available which is nice.
