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

I am a CTO who has connected this to a 2018 Mac Mini and use it for both work and personal activities. I also have a mid 2015 MacBookPro which I love for the clarity of its retina display. I run the latest and greatest version of OSX (currently Mojave) on both of these machines. Prior to this purchase, I had the mini hooked up to a 23" 1900 x 1200 Apple Cinema Display circa 2002 (that is not a typo). It was surprisingly good but always made me wish I was looking at retina-quality output.I'm taking the trouble to write this review because I found other people's reviews helpful in my decision to purchase this monitor (LG 27UK650-W 27). I've had it for 2 full work weeks, am extremely happy with it, and have avoided a lot of mistakes by reading other people's reviews. I'm paying it forward.Advice:1) use a DP cable not the HDMI cable; I used this and it worked immediately with no hassle: CHOETECH USB C to DisplayPort Cable 4K@60Hz, USB 3.1 Type C to DisplayPort Cable2) be careful not to touch the front of the panel when unpacking it, moving it, adjusting its height or rotating the display; always do this from the top/bottom or the sides; it's not hard to do this - just be mindful3) know that the display does not have speakers, just a stereo out jack4) download the Onscreen Control app from LG's website; makes it easy to do the adjustments you will make most frequently5) spend a little bit of time learning to use the joystick located underneath the bottom frame so that you can use the built-in Onscreen Control Center. This lets you do more advanced adjustments.6) if you are using VMware Fusion (I run Windows 10 for certain things) you will need to go to the Virtual Machine => Settings => Display panel and deselect "Accelerate 3D Graphics" if you want to go full-screen with it. Otherwise it will be unusable. But you *can* can select "Accelerate 3D Graphics" and use Single Window mode. *** Subsequent correction: if you like you can leave "Accelerate 3D Graphics" selected and increase the amount of Shared Graphics Memory to the recommended amount (for me 1024MB).7) familiarize yourself with how to use MacOS's Spaces (multiple desktops); you won't want to maximize your apps to full-screen; they're just too big. But you still may want to place apps in different desktops.After connecting the DP to USB C adapter, turning on the monitor and powering up the Mac mini, it just worked. I knew I was in a good place when I entered System Preferences => Display and saw the same scaling choices as I see on my MBP. See the first image. The default resolution was too big for me (1920 x 1080 @ 60 Hz). The second image shows my current choice (2560 x 1440 @ 60 Hz). Obviously screen resolution is a matter of personal taste; I find this to be the right trade-off between font size and screen real-estate. The text as I type this has the same clarity as my retina display but on a big monitor. I suppose I might decide to shrink the font smaller (3008 x 1692 @ 60 Hz) to get more real-estate. The point is that I have the choice - either one looks great.Other Observations:* Night shift works.* Screen saver / sleep mode works.* You will be surprised by how far away the menu bar at the top of the screen is from many of the apps* As near as I can tell, the display has no dead pixels. Or maybe they're so tiny that I just can't see them.* I don't see the IPS bleed that some people complain about. Both my Windows and my Mac backgrounds are black and I don't perceive bleed. (See two images).* The stand feels sturdy to me.I am not a gamer. I work with text and numbers all day long and my apps look great. Although I am not a graphic designer, I spend a lot of time on images and graphs and they look great to my eyes. I can't comment about the calibration of the display but the colors look good to me.After 2 weeks of extensive use I'm a happy camper. Fingers crossed that the monitor's reliability is as great as its looks.I hope this helps.Just an update: after 6 weeks of using this monitor my view hasn't changed: I continue to love it.Another update: 6 months in and no change to my review. Not a moment's problem with the hardware.

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. ^_^
