LG UltraGear QHD 27-Inch Gaming Monitor 27GL850-B, Nano IPS 1ms (GtG) with HDR 10 Compatibility and NVIDIA G-SYNC, 144Hz, Black

No complaints. And Im using and hdmi. Will change to display port soon. Keep in mind. I was on a Samsung curved 1080p 60hz monitor before. This blows it out! Just FYI. Coming from a curved screen to a flat. Its like the flat is curved backwards because your eyes cant make sense of a flat screen. Lol no points taken for that. I expected something weird. So yes. If you are using a 1080p. 60hz. This is a HUGE step up in my opinion.

First off, I got this monitor to replace my 32 Acer Nitro 1440p monitor. I wanted something a bit smaller that had higher color accuracy. This thing absolutely delivered on all my expectations and exceeded them in terms of picture quality. The display is crisp, and the color calibration is on point right out of the box. The blacks are very deep as well, Im genuinely shocked how nice the blacks were for not being OLED. The best settings are also enabled by default for least amount of motion blurring and crispness at high FPS. I run a 6900 XT and 5950X in my system, so I have all the horsepower needed to push the full 144FPS needed. It holds up well. I would definitely rate this as one of the best monitors on the market, especially at the price point. I havent had any issues thus far, but Ill update if I do.

Out of the box, the colors and contrast were dreadful. Everything looked extremely washed out. I went through all the different menu options and nvidia settings and was able to look it somewhat better, but was honestly going to return it because my old 1080p 60hz TV that I was using as a monitor just looked far, far better which was sad because I thought the improved resolution and refresh rate would result in a vastly superior experience. So I was digging around online and I came across a few people talking about changing the color calibration. I checked rtings score for the monitor (much like other sites, this monitor has a fantastic rating on rtings) and I saw that the out-of-the-box color calibration was terrible but after calibration it looks fantastic. I ended up loading the color calibration profile that rtings provided and the difference was like night and day. Colors became a LOT more accurate and the contrast was vastly improved. The blacks and whites still arent perfect, but it no longer looks like the entire screen is covered by a gray plastic screen. After tinkering with the settings for HOURS (with color profiles, the monitors menu settings, and nvidia settings) I finally have the monitor looking good but it took way more work than it should have.

LG has certainly set the bar here with these monitors for both quality and price. I think a lot of people will be debating the LG 27GL83A-B and the LG 27GL850-B; I’ve had both and I immediately knew the decision was to keep the LG 27GL850-B. I was blown away when first viewing images on the 27GL850 when comparing to a TN panel, and this was not something that I felt with the 27GL83A at all. My specific unit has no noticeable IPS glow (orange tint) and has very minimal back light bleed that would only be noticeable in a completely dark room. Compared to its lower priced counterpart, I think the Nano IPS display makes a world of difference for quality and the ability to reduce that IPS glow and back light bleed. Blacks are deeper and more consistent on the 27GL850A and colors really pop on the wide color gamut panel. Pros: + 1440p @ 144 Hz + Good viewing angles + Gsync certified and Adaptive-Sync ready + Supports wide color gamut and provides a very good sRGB emulation profile for those that do not like the saturated look + Nano IPS provides decent black levels for IPS panel standards + No IPS glow visible to eye (specific to my monitor) + Very minimal back light bleed (specific to my monitor) Cons: - Advertised 1ms (you’ll need to select the “fastest” response time setting, but you greatly sacrifice quality for minimal benefit) - Contrast level is lacking due to panel technology - Stand is on the cheaper side - HDR support is a gimmick (can accept HDR signal but this monitor only has a 350 nits level)

I bought this with the idea that I would easily have a easy advantage over other consumers of a different product due to lower resolution and low fps, and sure enough, I was wrong but at least the visuals look nice and the gaming experience has now become more enjoyable due to the upgraded hertz on the monitor. Warzone 2 is even more lit now. I’m better than the majority, thank you. Minecraft also runs amazing with mods.

Below is my original review and Im leaving it there so people can learn from my mistake. I ordered a second one of these monitors thinking it must have been defective. I was wrong. When I opened this new one, before I pulled everything out of the box and set it up, I just wanted to test it first so I just pulled the monitor out of the box along with the power supply. Same thing happened as the previous model using my Display Port cable, which was brand new when I tried the one I thought was defective the other day. Then I tried the DP cable that was in the box and then the HDMI cable. No difference. Take a look at the pictures to see what Im talking about. The dim one is the LG 27GL850-B and the bright one is the ASUS PB278Q. I figured two monitors being damaged in a row is very unlikely so I thought Id browse through he menus again to see if there was something I missed on the first one. I came across Display Port Version. It was set to 1.4 so I thought let me see if changing that would do anything, just something, anything and I changed it to 1.2 and BAM, nice, bright colors. I changed it to 1.1 but there was no difference between that and 1.2 so I put it back to 1.2 remembering seeing somewhere my MSI GTX-1060 mentioned something about Display Port 1.2. Tech support emailed me back when I sent them my complaint but it didnt mention anything about checking the DP Version. I replied to LGs email telling them of my huge blunder but in my defense, someone should have told me to check this, even if not in the quick start guide or the manual but at least in the tech support email. Anyway, this monitor is just as bright as my ASUS PB278Q, which is five years old and this one isnt even set at its brightest. Im happy and I plan on ordering one more so I have two of the same and Ill keep my ASUS as a backup and maybe for my laptop. OLD REVIEW: The colors are muddy, at best and are far from Color Calibrated and no where near LGs claims of a Wide Color Gamut. The blacks are dark grey at best when I have it set to a bright enough level where I can actually see it. The images this monitor displays doesnt even come close to the ASUS it replaced. I even tried to adjust the colors in the Nvidia control panel with no success. Lastly, this monitor is not bright at all. It has to be the dimmest monitor Ive ever used in my 26 years working with computers. This is not a $300 monitor. I wouldnt pay $100 for it. So, it gets returned.

Overall quality is great. You can adjust the monitor stands height with a good range.

The level of responsiveness that makes it a good fit for casual and competitive gaming. The 1440p resolution offers a crisp and detailed picture with 120hz on my Xbox Series X is just beautiful. Setup is really easy to do, even though I went ahead and got an arm for it, but the stand is great to use. The monitor is great for work also, as it provides 2 HDMI ports and 1 DP port. It also has a USB hub, which i dont use but hey, its there. The price here on Amazon, goes up and down, I missed out when it went as low as $296, so i got it for $346. Still a great purchase.

This and the 27GL83-B are two incredible monitors, the difference being mainly only in a slightly wider color gamut and the inclusion of 2 USB ports on the GL850-B. For the price, you get a quality IPS monitor with 144 Hz refresh rate, adaptive sync (both Freesync and Gsync compatible), and a fast response time. The IPS panel suffers from lower contrast ratio you might find on higher end models and those using even average TN panels, but the colors really pop (the advantage of IPS). It has wide viewing angles (another feature of IPS panels) but for computer monitors viewing angles are not nearly as critical and should be low on your list of features. I took off one star because the monitor claims HDR 400 but HDR 400 is basically nonusable, the HDR performance on this monitor is mediocre at best and I just leave it off and I am happier with the colors and overall experience. Pros - IPS panel for great colors - 144 Hz refresh rate - Adaptive Sync - Price point for these feature sets Cons - Poor HDR performance

I picked up one of these in 2020 and absolutely love it! The colors are very important to me for print and photo work. The contrast is excellent as well. Its been a fantastic monitor, Id buy a secod one in a heart beat if I needed one.
