The LG 32UK550 is an excellent yet affordable 32″ 4K monitor for gaming, basic content creation, and other multimedia enjoyment.

  • +

    Good value for the price, High contrast ratio and wide color gamut, Crisp image quality due to high pixel density, Plenty of features including FreeSync over HDMI, Built-in speakers and height-adjustable stand

  • -

    No sRGB color gamut profile, Rec.709 will have to suffice for content creation, Design lacks swivel and pivot options, the stand is prone to wobbling, Minor ghosting in fast-paced games, mainly in darker scenes, Viewing angles aren't very wide

This is a nice big monitor that would have worked for my non-gaming, completely business needs except that the screen sharing and splitting is a pain and in the case of different inputs impossible.

Positive: 4k is definitely an advantage. This is a clear improvement over lower resolution, even at this screen size.Negative: After using exclusively IPS panels for a while, I am having a hard time getting used to this VA panel.

The display is good, nice color and crisp text when using spreadsheet. However, there are two things that I don't like. 1) No documentation so it took a while to find the control button. And some more time to figure out how to use it. 2) Does not support MHL (Mobile High-Definition Link) directly.

Perfect Size for Desktop. Large but doesnt require you to move your head to sweep the surface. Can also get a second monitor on most desks. Not PERFECT with Color but if you fiddle with the settings you can get it pretty darn good. I feel comfortable using Photoshop after a bit.

I find this monitor optimal for daily work (office). Good balance quality/price and I don't have the ambition to use it for gaming or photoshopping. Probably it can do it but for my purpose is perfect. Good response time, good contrast, perfect high definition, right size

I bought this by recommendation of the sales associate, I came in looking for a different LG 32" and he asked me for what I was going to use it for, the one I wanted was more for gaming which I don't do and he recommended this one, I'm so glad I followed his suggestion, color is awesome.

This display is everything I want it to be and nothing I don't want it to be. The text is perfectly clear. I had to put the OSD menu to photo mode and tweak the black level a bit to avoid a little ghosting with black text on a white background, but now it's wonderful.

First, my desktop specs include an Intel core i7 -8700 CPU, 16 GB Ram and one Nvidia GeForce RTX 2080 graphics card.Second, my main purpose for this monitor is word processing and reading text. As far as brightness and color are concerned both are good enough for me.

I am using this monitor to connect an HP Elitebook 745 G6 via Thunderbolt over USB-C; some of my impressions are colored by that The positives Coming from a 1080p monitor, the crispness of the screen is night and day Using this as an office productivity tool has been excellent Monitor is...
