What people are saying

Rated 5 out of 5 by from Amazing I bought one of these monitors 6 months ago. I recently decided to go with duel screens and liked this one so much I didn't hesitate to purchase another. Colors pop and image is awesome. I've always been very happy with LG.

Rated 5 out of 5 by from Quality and Compatability I bought this monitor to replace a 4K UHD monitor that wasn't built very well. This LG monitor is the same size and has similar specifications, but it is SOOO much better in every way! The colors are more precise, the games don't blur, movies and pictures are beautiful. The design of this monitor is solid compared to my other one, the stand fits tight and doesn't let the monitor wobble, the bezel is clean and sharp-looking... I did a good bit of research into display technologies and various manufacturers to figure out the all-around best display for what I do, and LG is where it's at! They apparently lead the way in display technology, and I've got an LG 4K UHD TV that I bought around 8 years ago that still works as perfectly as the day I got it. I can only reason that this new monitor will last too. It is connected to several different devices and performs wonderfully on all of them. No time-consuming installation required. I just plugged it in to the devices and it did what I bought it for. It's got LG's easy-to-use UI, too, so I have complete control of all the settings... I could keep going on and on about how awesome this monitor is, but I'm about to get in on some serious 4K HDR gaming action!

Rated 4 out of 5 by from Excellent screen I was needing a “second” screen to use with my laptop at home, but did not want to spend lots of money in a screen. So, based on the reviews, I found this an excellent choice and decided to give a try. I do not regret, it is an outstanding screen.

Does the White plastic piece over the vesa mount come off or do you screw through that part?

Asked by: KWIZ
Install the monitor at least 100 mm (3.94 inches) away from the wall and leave about 100 mm (3.94 inches) of space at each side of the monitor to ensure sufficient ventilation. To install the monitor to a wall, attach a wall mounting bracket (optional) to the back of the monitor. Make sure that the wall mounting bracket is securely fixed to the monitor and to the wall.The wall mount kit includes the installation guide and all necessary parts. The wall mounting bracket is optional. You can obtain optional accessories from your local dealer. The length of the screw may differ for each wall mounting bracket. If you use screws longer than the standard length, it may damage the inside of the product. For more information, please refer to the user manual for the wall mounting bracket. Use the wall mounting bracket and screws that conform to VESA standards. Damage caused by the use or misuse of inappropriate components will not be covered by the product warranty. When measured from the back of the monitor, the length of each installed screw must be 8 mm (0.3 inches) or less. If you need further information, please contact our computer specialists at 800-243-0000.

I purchased the 27UL600-W for photography. The section on setting the GAMMA is vague, Which mode would be equivalent to Gamma 2.20. Also, the Black level control. Does setting it to low, increase the dynamic range.

Asked by: Terrylw64
The Gamma settings for the LG 27'' Class 4K UHD IPS LED Monitor with VESA DisplayHDR 400 (27'' Diagonal), Model # 27UL600-W are given as modes. Based on a gamma value of 2.2, if the square frame appears dark, the monitor's gamma value is low. If the square frame appears bright, the gamma value is high. You can adjust the gamma value by changing the monitor's brightness settings or by adjusting brightness in the driver menu for your graphics card. As the owner's manual advises, "the higher the gamma value, the darker the image becomes. Likewise, the lower the gamma value, the lighter the image becomes"...^IFV
