I have four 4K monitors:LG 27UN850-W X2, one desk dual monitor setup (will be referred below as LG)Dell U2720Q X2, one desk dual monitor setup (will be referred below as Dell)I use LG, my spouse uses Dell.In my mind LG is better to fit my needs.From my spouse's point of view, Dell is preferred over LG.1. Why does LG better fit my needs?a) both LG and Dell have anti-glare screens. But I found Dell reflects a little bit more than LG. I have a “designer white” desk. Dell’s reflection is noticeable especially during the evening when using the desk lamp and watching videos. On the other hand, LG does not distract my attention due to glare. The Dell glare issue could be a combination of my desk color and light source setup. But given the exact same setup, LG does not distract my attention due to reflection.b) LG has ports arrangement on the back, rather than at the bottom. I’d like to try different gadgets during the past weeks. The LG’s design makes it super convenient to plug/unplug cables, firetv stickers. Dell’s traditional port design also works well thanks to the best ergonomics stands (will come to it later). Adding devices/cable to Dell just by simply rotating the screen.c) LG has a user-friendly screen control joystick. Dell’s traditional button is not comparable. Again, because I’d like to change settings, and try different gadgets.2. Why does Dell better fit my spouse's needs?Ergonomics, ergonomics, ergonomics!My spouse needs ergonomic monitor stands. Dell’s design fits the bill perfectly. A complete freedom of adjustment with extremely wide ranges, at any direction.3. What do the two monitors share in common?They are all very good monitors for regular day to day work/entertainment. Again we are not professional graphic designers nor video editors. For average users like us, you cannot go wrong with either LG/Dell. For most of the time, all our monitors work in reader/office/text mode. When it comes to entertainment, LG/Dell, for me, do not make much difference. I cannot tell the difference when watching videos or playing games, or editing family photos. They look pretty much the same for casual entertainment. I also placed the LG/Dell side by side, playing the same youtube 4K HDR videos with all monitors in full HDR settings, but I cannot tell which is better. They all calibrated to their own standards. In their own “reference frame”, they all look very beautiful.Btw, isn’t the best entertainment to find a job to do what you like? The office/text mode might be the best entertainment mode for me :-)Finally, because this is my serious review under this LG product tag. I will add 3 more points for LG only:1. LG has a bulky voltage transformer shown in the picture. The power cable on each side of the voltage transformer is about 55 inch (total about 110 inch including the transformer in the middle), long enough for any home office setup. However, for a standing desk, I have to spend a bit extra effort to hide the bulky transformer in the cable management tray.2. One of the LG monitors has a very tiny issue with the stand. I returned it and bought a new one. The problem went away.3. LG has a builtin speaker that can be easily used with fireTV stick 4K, just plug and play. If I want to control volume, I’m using the LG monitor joystick, or a separate speaker or a bluetooth (Jabra evolve 75), where output device with builtin volume controls. The joystick also makes the hdmi input switch very easy, fireTV to Nvidia Quadro, very smooth joystick operation. But better to get a 4K HDMI switch.
