i have dell xps 8900 desktop with intel i7 6700 cpu - nvidia gtx 745 gpu. nvidia said the gpu only support maximum 4k at 30hz but when i turn on freesync on this monitor it supports 4k at 60hz...if i turn off freesync it only support 4k at 30hz. just turn on freesync at monitor setting.

Impressive resolution, clarity, brightness, and color rendition (although I am no photography expert). Running them at 15% brightness, 50% contrast, and 0% sharpness. Computer output resolutions set to 3200x1800 on two of the monitors and 2880x1620 the other.

I've been using this monitor for coding and software development and it's really helped me. My previous monitor caused a lot of eye strain but this one has been a real godsend. The text is crisp and the colors are rich. Highly recommend!!

4k, IPS, slim bezel... what else can I say. I DO play games on this however, it really shines when it comes to my photo and video editing. LOTS of realestate to keep all my windows stacked. On par with my MBP retina screen as I use this as my second monitor. 10/10 would recommend.

A spectacular picture and remarkable clarity make the price of admission acceptable. My first 4K monitor and I've loved it since day one. I can't say enough about the quality of the monitor and how it has ruined me for lesser monitors.

once set up, it is an excellent display. i set it up using an m1 macbook pro. the color rendition is nearly a perfect match to the m1. in fact, the white of the monitor is slightly cleaner and more white than the m1 display.

Bought specifically for the ability to do PIP and PBP for upto 2 computers at a time. With this it performs excellent and in sole 4K mode the picture is awesome. The only annoying thing (and why it got 4 stars) is the monitor will go to sleep after an hour of inactivity causing a reset of window...

Good monitor, Nice 4K resolution, but has a really annoying high pitched noise that hurts my ears.Also lacking a monitor height adjustment.

I originally purchased LG 27UL500 due to the highly rated reviews. It wasn't a bad monitor but build quality suffered from uneven space between the bezel and screen so I ended up returning and purchasing Samsung U28R550. I'm really enjoying this monitor and I think it looks better in my eyes.
