What People Are Saying

Rated 5 out of 5 by from Great Features, Great for Gaming I bought this with high expectations, and I must say they have been exceeded. The picture quality is stunning, and the Freesync ensures all frames are smooth. I would definitely recommend this product. [This review was collected as part of a promotion.]

Rated 1 out of 5 by from Dirt under the screen I have exchanged over 5 27ud59 at best buy because they all had different problems such as, dead pixels, broken stand, missing pieces etc. I decided to step up a bit and pulled the trigger on the uk650. I cant believe how bad the quality control is at LG. Again problems ! A very noticable black spot/ dirt on the bottom left corner. I am just dead tired, now i need to pay restocking fee at the store i purchased it. I will never buy LG product again. What a ripoff

Rated 5 out of 5 by from Amazing 4K hdr10 monitor This is an amazing monitor for the Xbox One X or PS4 Pro. I have an Xbox one X and it performs incredibly. The picture looks so good and I haven’t had any problems at all! Set up was a little confusing at first but overall not bad! Make sure you look up some recommended settings in order to really make your monitor’s picture pop. Overall, the best monitor I have ever had and for the price, it’s the best on the market right now.

Rated 4 out of 5 by from Good for the price Image quality is superb, plenty of inputs. Sound output from your DP or HDMI Subtracting one star for not having any USB ports. Why not add a USB hub? One word of caution, 4k support in windows is still spotty. I had all kinds of problems when I turned on "HDR/WCG" in the Windows 10 display options. Keep that off and use your GPU's driver to enable 10 bit color and you'll have much better luck. Also remember that the game needs to support HDR for there to be any benefit.

Rated 5 out of 5 by from Excellent. Attention, it is VERY matte, NOT glossy Hi. For a very low price this monitor offers about everything including a great looking image. DisplayPort and 2x HDMI are handy, both support 60Hz. I did use the (deep) menus to tweak the image but now, it is impressive. The display is extremely matte, meaning it does not reflect light which is great to see correctly even in brightly lit environment, and it does not strain your eyes. So... also great for business and photography. For Photo editing, I noticed the blacks aren't as deep as the VERY glossy MacBook Pro retina display, so the LG seems less sexy, but when calibrated to be very accurate you can definitely do great photo work on there. BTW the factory calibration was in fact very good and LG provides the data sheet of your particular copy of the monitor. All in all a GREAT purchase. BTW the foot is great, but I mounted mine on articulated arm which is nice. Just pay attention as the connections on the back may interfere with the 100mm VESA mount which must be indented on the right side (when looking from the back) to allow for connections to be exposed. BTW the bezels top, left and right are very thin. Nice.

Rated 5 out of 5 by from Great, vivid colors! I bought this monitor a month ago and it is the best one I have used, to date. The colors are the best I’ve seen from similar priced monitors that I’ve owned in the past, the build quality seems to be top-notch, setup was very simple, and most importantly - the monitor has been running brilliantly following extended use.

Rated 5 out of 5 by from Best Console Monitor Available This is the best monitor for the console. LG does not want their product reviews to include information of other competitors or products, so all I can say is that this monitor is MUCH better than the 4K monitor I already owned and at half the price. If you are looking for a monitor for either of the two biggest 4K compatible consoles this is the one to purchase. This monitor supports all features on the consoles and will give you a green check next to all the features in the Display & sound 4K TV details ;) I could not be any happier with the monitor. The build quality, picture and easy to use menu system makes this one of the best purchases I have made. Plus, the price point is great. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Great 4K HDR Monitor for Xbox One X! This monitor is simply incredible! It is a perfect fit for my Xbox One X. The display is nice and crisp and very responsive. The colors are very accurate and not over saturated. I really didn’t need to change very many settings right out of the box. It also has AMD Freesync which the Xbox One X supports. It has made the games I play feel much more responsive and smooth. I’m very happy with my purchase! [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Better than the majority of monitors out there! I have owned three different brand 4k monitors hitherto, and I can definitely say this monitor is the best. This monitor is sleek with a minimum border and I really like that. Even though this is my first hdr10 monitor, and I realize it is not full hdr10, I was not disappointed with the picture generated. I am not a picky person. The only gripe I have is that it is not full hdr10; otherwise, I would give it 6 stars. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Quick and Simple, Bright and responsive I added the LG 27UK650-W as a workspace expansion for my MacBook Pro. I commonly have multiple applications open and the UHD resolution gives me plenty of desktop real-estate in which to improve my working environment. The Monitor is bright and was quick to setup. For my use it really needed a USB-C port or two and it would have been perfect. I know LG has some with USB-C but they weren't in the same price point. Great monitor, and Yes I'd buy it again.

Rated 4 out of 5 by from Would give 5 stars but...... My monitor came with minor IPS bleeding on the top left corner of the screen. The only time its noticeable is ob a black screen, but is unnoticeable when picture is displayed. Overall I am happy with my purchase and the picture looks fantastic with my Xbox One X.
