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

ive been using a va curved panel for years, and i decided to try this one as my new main monitor. both monitors are of course 27 inch, and the color is very noticeably better on this lg monitor. it CAN do 1ms response, but you will get overshoot in the pixels which will result in white shadows around the moving images on the screen, so i keep it at the 4ms setting which doesnt hinder my gaming at all, even in games like call of duty, its not even noticeable to me. if youve been using a curved panel for years, using this flat monitor will likely look like its bent backwards, idk why but maybe its just cuz my eyes are used to seeing a curved display. i also recommend using a DP 1.2 cable if you want to run hdr or any high refresh rate settings but this is just personal preference mostly. just depends on what you want out of the monitor. this thing is amazing, and it fits well on a vesa mount. i recommend this monitor to anyone in the market for a good quality monitor, especially if they like 27 inch panels

Within the first few months of owning this monitor I noticed a crack in my screen on the upper right quadrant that wasnt there previously. Im almost certain it was not of my own doing since I dont touch my monitors unless its with a microfiber cloth to clean them, and I dont remember bumping into it with anything either. On further inspection, the crack seems to be almost exactly 6-8 pixels wide, and is completely straight horizontally, like perfectly so, which I think also rules out that I scratched it somehow. Im thinking that maybe one very small component got too hot and the screen cracked there as a result or something, I dont know. Again, I dont touch my monitor and I dont use sharp objects around it either, so I was pretty surprised to see this. At first I thought it was some dead pixels. Some might think such a small crack isnt noticeable in normal use, and sometimes it isnt on darker backgrounds, but on anything lighter though its quite noticeable, like a permanent small hair which you cant wipe off no matter what. Its a bit hard to see in the picture, but there it is.

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.

This is a good monitor for sure, it was very easy to get set up on its stand that comes with it. The picture is very clear and crisp, everything looks smooth when using it to game. The only negative thing about this monitor is that the picture kind of looks like it has a backwards curve to it, now this may just be because i was using a curved monitor for years before i got this monitor so my eyes may just need to adjust to using a flat screen monitor again. Other than that this is a great monitor, also the stand that comes with it is not overly large so it does not take up much room on your desk. The stand can also adjust for height or even tilt if you want to use your monitor in a portrait view instead of the standard landscape view. you can also tilt the monitor to have the screen angled a bit more down or up.

Dont know what to tell you. Runs perfectly fine with no ghosting while gaming. Since it is my first monitor, I cannot not tell you if it is worth like $250-300 (when I got it). But, it is definitely a worthy contender if youre not a competitive player and just want to enjoy the scenery. Quick reminder: if you want to have 144 fps, you should first check in your settings under Display.

What I liked: + Great response times: I dont think anyone is going to miss their 144hz TN panel after using this. + Near perfect gamma 2.2 tracking on default gamma 2 mode + Average Delta-E around 1.5: not bad + Amazing color gradient handling when set to 10bit mode + No BLB or dead pixels What I disliked: - Default whitepoint is too cool (measured 7200K) and none of the provided modes gave an actual 6500K. Luckily, with a colorimeter in-hand (Colormunki Display) I was able to calibrate to 6500K with minimal loss of contrast by adjusting the RGB gains. - IPS glow isnt any better than my old IPS monitors. Youd think now that tablet and laptop IPS panels have mostly resolved this issue that monitor panels would do that too. Other notes - Contrast measured at 870:1, a bit low for an IPS panel although I cannot subjectively notice a difference in black levels compared to my other IPS monitor that measured 1150:1. If youre looking for deeper blacks youre better off with a 3000:1 VA. - Gamma mode 2 is the only gamma mode that was calibrated at the factory. Changing the gamma mode to modes 1,3, or 4 resulted in a white point of 6300K, contrast ratio increased to 1060:1, however the gamma tracking is really bad on these modes. - Gamma mode 1 results in an approx gamma of 2.0, mode 3 is approx gamma 2.5, mode 4 is approx gamma 2.3, but again the gamma curves on these modes are messed up and do not conform closely to these numbers so I ended up using gamma mode 2 and just correcting the white point.

About 6 or 7 years ago (might not be exact to be honest), I purchased one of Acers 1st 144hz, 2k, IPS gaming monitors the first or one of the first of Acers Predator line. The Acer monitor has been great, but lately Ive been craving something a little more for the monitor space, since its been quite a while since ive had this monitor (actually a pretty good monitor even for todays standards). I decided to go with LGs 850b Nano IPS monitor since i really enjoyed a new LG Nano Cell TV I just purchased recently. Once I turned on the monitor, calibrated, and turned on the correct settings I was blown away by the noticeable difference from my previous 2k, IPS, 144hz monitor. Theres a distinct characteristic I like about Nano cell displays in particular, where the colors are more vivid than other displays. The images also appear to be more smooth than my previous display although it is running at the same 144hz. I can easily see this monitor being one of the best for the price point although I havent tested other monitors. The display that I got came with no issues, no dead pixels, and the backlight bleed does not bother me much if at all during normal use. With the recent Nano cell TV I purchased, and this monitor, LG has truly one my heart over for their display technologies. I have a Samsung QLED TV as well, and the Nano cell TV (which was way cheaper) was a much better deal and better quality. LG has done a spectacular job in the creation of this display and their recent line of TVs and offer a competitive price for the quality. A+

It does give a really nice picture. Although I highly disagree with all of these reviews (here and on the web) where they say the viewing angle is pretty good; its actually pretty bad. For instance, if I have a dark background everything looks great straight on, but when I stand up and look at it, it takes on a reddish hue. I have an old 2nd monitor (Acer S231HL) connected via DVI that doesnt do that at all. It has to be 15+ years old. Other than that, my main complaint with this monitor is that the windows on it are always getting moved all over the place whenever it comes back on after a power off. Windows on my second monitor get moved over to this monitor; other windows on this monitor get moved from the top right to the top middle-right; icons lined up to the left get rearranged, etc. None of this ever happened on my previous HDMI monitor, only this high DPI Display Port monitor. Its actually a really big deal rather than a minor annoyance after youve been having to rearrange them several times daily.

Ive only had this monitor for about a week but I feel like I have had enough time to make up my mind about it. I came from the VG248QE(TN panel) and immediately I could tell that the colors were a vibrant beauty and not at all saturated... except for the color red which is a little bit redder than it should be and thus caused Caucasians to have a little pink tint on them( you could say they are colored now, so its a welcome change of pace). The change from 1080p to 1440p was also something instantly noticeable. Free sync works great with my AMD GPU. HDR Effect feels like my eyes are getting attacked by a box of crayons, it not bright enough and it doesnt have local dimming so steer away from this if you want True HDR. As a competitive gamer I can without a shadow of a doubt say that the 144hz is giving me a gaming edge in Solitaire and Minesweeper. Unlike other gaming monitors this one didnt go with the disgusting tootsie roll RGB gamer aesthetic. Build feels and looks premium. The stand is metal and the monitor is plastic, but it feels like quality plastic, if you know what I mean. NSFW content looks great too but youll have to shill out cash to see content in 1440p. All in all, great monitor I recommend it!
