AOC - CU34G4

All 3 are VA pannels, VA is not my favorite, I prefer IPS or ultimately OLED, but VA keeps the price point down. The AOC and Xiaomi are both 180hz, the Samsung is 165. The Samsung and Xiaomi are 1ms response time, the AOC is faster at .5ms. The Xiaomi and AOC are 350 nits, the Samsung is 250. If you go by pure specs the AOC is the best and the Samsung is the worst. That being said Samsung has the best reputation and makes their own panels, so in theory it should be the most reliable, but it could just be a case of paying for a well known brand.

I've just bought a cheap VA 34" ultrawide (A damaged box AOC CU34G4 for £210), and the jump in picture quality from my 6 year old Samsung VA panel monitor is night and day. I'm new to ultrawide monitors and was worried at VA panels would be horrible, and that smearing would be a huge problem, but it honestly hasn't. If you're used to something modern and high end, maybe you'll really notice some of these things, but coming from where I was, this is a night and day improvement

I recommend the AOC CU34G4 WQHD 180Hz AdaptiveSync Curved 34in Monitor, I have this monitor and it has been a great budget option for its level of performance, it is VA but I haven't noticed much ghosting at all and the curvature level makes the poor viewing angles not very noticeable

Keep in mind this monitor did not come with a cable good enough to run at 180hz and it cannot use a hdmi 2.1 it needs a good display port cable to reach its Max fps. I used the monitor with a system a little worse than yours and I couldn't really run things at high graphics and fps at the same time but I could do high fps low graphics or low fps high graphics for most games

for this pirice range i don't think there are better option, anyway id going for the aoc, for fast va e 180hz and i does not have the problems of the Samsung one

AOC 34 180 RAPID VA is a good buy, so is the phillips evnia, just jmake sure if going VA get the 0.5ms response RAPID VA not old VA

I have an AOC CU34 for work. Relatively inexpensive, ultrawide, and comes with a KVM to make laptop docking easier. It's my go-to recommendation for WFH

34". All the way. We have had AOC x 2 with zero issues, great monitor. My lad is currently on an LG 34" which seems to be fine, little bit of bleed. My daughter is also on a 34" Viewsonic, i'm on a 49" uw. My two main gaming buds are also 34". Both with 3060s. For gaming, gotta be 34" curved, it's a beautiful thing. Imo, i would stay away from nzxt myself.

Having the same usage as you, i have a AOC 34" Ultra wide, and i'm thinking to go for a 32" 4K specially because of the height resolution.
