Overall, it's a very nice monitor with a solid build quality

Love the curve and 4K quality of the monitor

Do yourself and everyone else a favor and don't support this kind of awful quality, especially at the high price being charged.

I liked the quality of the higher resolution display, but not at the cost of low frame rates

I'll chalk that up to poor quality control on Acer's part

This monitor would've been a 4 star but due to me receiving two bad monitors I've given it 1 star for poor quality control

Very poor plastic build quality

Either I just got very unlucky or Acer has terrible quality control

This monitor is expensive, so one would expect a top-quality product, with excellent customer service.

The overall build quality on the Z321QU feels much improved, with sturdier plastics and vastly reduced back light bleed around the edges

The quality of this monitor is excellent....once you take the time to configure the settings

The build quality is great

-Love the view of the monitor-Looks great on 1080p for console games and the PS4 ProCons:-My biggest con is the built quality

Also, from the review below me, I do have to agree that the sound quality is not so great... highly recommend speakers or use a headset which i'm currently using.

Nothing beats a good quality headset though

These are the only reasons I rate this monitor 4/5,Otherwise, everything is absolutely perfect, I love the build quality, the resolution, refresh rate, and of course the G Sync.

The display not working poor quality

Thank you as I am one of those humans that leaves fingerprints on everything

n’t getting the full capability of my 1080ti
