LG 27UK650-W 27” Inch UHD (3840 x 2160) IPS Display with HDR 10, sRGB 99% Color Gamut, AMD FreeSync Technology, 3-Side Virtually Borderless Design

Who am I? A techy, with disposable income for new toys within reason. What am I using this monitor for? Xbox One X.I have NOT used this monitor with a computer yet...yet.Okay so I waited since like December for this thing, after looking at and comparing countless monitors. Finally an "HDR" Freesync Monitor, with good response time and 4K.... Every Xbox gamers dream right?I fired this thing up yesterday and boom.... underwhelmed..... it looked bad out of the box, then i played with all the settings.Turn the Brightness WAY up, and leave the black enhancement at low. And all of a sudden everything looked amazing.Day 1:Playing fortnite doesnt have HDR, so I loaded up destiny 2 (ew) for to see how to activate HDR, since i couldnt find any settings to just turn it on.Boom, on top right corner it displays HDR, and when you go into the settings its an entirely different picture menu, with a few different HDR settings, including a GAME HDR mode. I do not think you can have HDR on, and the input lag booster or freesync enabled at same time, as When HDR is on, the game settings menu gets grayed out. The game looked INSANE in 4k with the HDR mode on, so crisp and saw colors I had never seen before. For what its worth, the HDR mode that enables when you play an HDR game is PLENTY bright. It only goes up to 450 Nits of brightness in this mode, but for a 27 inch monitor, that is right in front of you, any brighter and you may have to look away or tone it down for gaming. So for all the people mentioning that this "is not a real HDR monitor, its not even 600 nits" Think about what you are using this screen for first. If it is gaming, this is very good. The HDR on this screen is far brighter than a middle range LG TV I have that has "HDR" as well.PSA: Both HDMI ports support 4K/60HZ and Freesync.For NON HDR Games, There is a cool mode called "HDR Effect" which bascally turns any content into super bright super vivid colors, and that seems to work with the gaming features since it is not actual HDR.I will continue to update this review, as well as try different modes (Ex: Hook it up to a iMac 5k, a Macbook, a PC, and watch a 4k HDR blue ray on it over the next 2 weeks.

I've been using this monitor a lot now with my Xbox One X, and it really is amazing! I've tried other 4K monitors, like the Samsung U32H750, and the LG just blows it out of the water with crisp 4K, brilliant colors, and impressive contrast - and of course - HDR, which makes everything look noticeably better! I have a lot to say about this monitor and the best settings I've found to be useful with Xbox One X games and media. To start, here are the settings I tend to use for non-HDR content, which are games w/o HDR and YouTube:Picture Mode: HDR EffectBrightness 85Black Level - LowDeep Color OnFreesync - On ExtendedResp. Time - FastAll other settings are defaulted.On Xbox One X, Settings are as follows:Color Depth - 10bitColor Space - Standard (must be set to this due to HDR, trust me)HDMI - auto detectAllow YCC 4:2:2 - OnWith these settings, you will get a great picture when it comes to non-HDR content.Now, there is something very important to consider: make sure you have the monitor's HDMI Black Level set to Low because it needs to match with Xbox Standard Color Space. So make sure you have it set to Low Black Level. I'm pretty sure if it's set to High and you can't change it to Low, fiddle around with it like change settings on Xbox, then monitor, and eventually it will go to Low Black Level.The monitor's contrast ratio may be 1000:1, but lemme tell ya, it's very very impressive, especially compared to another 4k monitor I tried which had 3000:1. I thought the LG looked 10 times better!One of the reasons I got this monitor was for the HDR, and for those who think it isn't good because it isn't "true HDR 1000nit brightness", itlooks amazing, and most games look really good (MH World looks awful). Elder Scrolls Online looks really amazing with colors (make sure to turn brightness in-game way up), I mean just go to Coldharbour and you'll see :). Some games don't have great HDR though, so it's sometimes best to turn HDR off in Xbox Settings and go with Custom settings on monitor.The monitor has 4 HDR modes: HDR Vivid, HDR Game, HDR Standard, HDR Cinema.For gaming, HDR Game is the best and most accurate for colors, response time, etc. but if you don't care about accuracy and how you are losing life expenctancy of your monitor due to post processing, HDR Vivid can be spectacular with fantastic colors. HDR Standard and Cinema just looks too dim for me, so I always stick with Game.Now this monitor uses an IPS Panel, and it's probably the reason why the contrast, brightness and colors are SO GOOD. There is some IPS Glow, and it's luck-of-the-draw whether you'll have a monitor with a lot of IPS Glow, or just a little. I've been through 4 of these LG Monitorspast 2 months, and finally settled on the one I have now because I got it really cheap and my previous one's display sadly wouldn't turn on so I returned it. The one I have now has minimal IPS Glow, thank god, but just expect to see IPS Glow because it's on every IPS monitor.This monitor does use an external powerbrick unfortunately, but I mean, does it really matter? I have room for it, but the only thing I worry is when it gets really hot as my monitor is usually on for 10 hours a day.The only thing I have to complain with about this monitor is not being able to customize much settings when HDR content is detected or when using HDR Effect Mode.. This isn't a big deal though because most of the settings that are defaulted are actually what you want it set to.If you care about your monitor lasting for a long time, avoid using HDR Vivid (and HDR Effect mode) because they heavily rely on post-processing to create the amazing colors, contrast, brightness, but they are bad for your monitor's life-expectancy. I still use HDR Effect Mode all the time because it's too good...I give it a 4.8/5, must buy if you are in need of a 4k/HDR monitor for console and can get this monitor cheap like $385-490 or so. I got it for $435 and it's a steal for what you are getting! 500 is too expensive, but that's only my opinion lol. ^_^

Review after 2 years of ownership:LG Monitors are AMAZING!!! And if you put on the "HDR effect" in its picture settings, the screen looks WAY better than a Samsung OLED.
