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

Coming from an older 1080p, 24” 60hz Acer, this monitor is a huge improvement in nearly every aspect. It’s responsive, built well, looks amazing in 1440p, and when calibrated, there really isn’t anything I can point out except for backlight bleeding. It’s not terrible, but it’s something that catches my eye during low-lit scenes or with contrasty images. It kind of reminds me of a silver halide print and to that point, it’s not a complete detriment but a characteristic of this monitor. I assume it’ll get worse over time, but for the price, it’s worth it depending on the severity. If you’re someone who deals with a lot of dark tones or requires accurate separation of tones (b&w photography) you may find better options.

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.

I write this review as the former owner of 3 Asus PG279Qs and one PG279QZ. I was drawn to this realm of the monitor market because I do not believe that 4K displays are worth it at this particular point in time. As far as I see it, the majority are a compromise as the bandwidth requirements for running 4:4:4 chroma subsampling, an extended color gamut, a refresh rate of 144 Hz and beyond, and a resolution of 3840x2160 all at the same time will be much better served by DP 1.5 or HDMI 2.1 (proper HDR wouldnt hurt either). Although it could be argued that achieving 144 frames at 1440p is more resource intensive than 60 frames at 2160p, I believe the experience to be the most immersive, at least until 144+ frames becomes viable at 4K. Unfortunately, based on the price to performance ratio trend of the current generation of graphics cards (Nvidia’s in specific), it is going to be a long, long time until that is achievable at a reasonable price. All things aside, I can state with confidence that I’ve found my sweet spot for monitors in the form of LG’s 27GL850. It has addressed all of the quality control concerns that I’ve experienced throughout my quest of trying to obtain a high refresh rate, 1440p IPS-type display. Seeing as this is an LG product, the monitor can rightfully be referred to as having an IPS (In-Plane Switching) panel as this is their proprietary term for the technology that produces the wider color gamut and viewing angles. I did not buy this display because I am a hardcore gamer; I bought it because I wanted a quality monitor with good color reproduction, a uniform panel, and good response time. My purchase was based solely on the off chance of LG producing a monitor where quality control wasn’t an after-thought. Now that it has finally arrived, I am proud to report that this monitor delivers. The display has zero backlight bleed and excellent uniformity, contrast, and response time. White uniformity is even across the entirety of the screen while the factory calibrated colors appear accurate even next to my calibrated Dell. Outside of sRGB mode, the colors do come off as over-saturated, although some may prefer the added vibrancy of the Nano IPS technology (I did not). Black levels are on par with most other IPS-type displays that I’ve used despite the specified measurement coming in at a somewhat lower figure than similar displays. As for response time, it seems universally accepted by the monitor community that the fast setting is adequate in preventing overshoot. The faster and fastest settings produce undesirable artifacts known as coronas. Despite this monitor not having variable overdrive, I have had no perceivable issues when it comes to gaming as I do tend to binge on CS:GO from time to time. If I had to nit-pick, and I do because this is a review where transparency informs prospective buyers, I will say that the strength of the presence of IPS glow on my display falls on the moderate end of the spectrum. This could be due to the fact the panel is 27 inches, which is a decent amount of real estate for this phenomenon to occur. It is also important to keep in mind that this is something that varies on a per panel basis. Without a doubt, it is a consequence of choosing to utilize an IPS panel for one’s computing purposes. Regardless, it is nothing unexpected or anything that cannot be addressed by adjusting the brightness level as well as the viewing distance, height, and angle. Besides simply turning down the brightness, placing the monitor further away is one way to remedy the matter. Another way to minimize the glow is to position the screen in such a way that one’s gaze meets the center of the screen as IPS-type displays fare better when the height of the top bezel is of equal height or greater in relation to one’s eyes. A final tip is to manipulate the screen’s tilt angle as oftentimes angling it upwards reduces glow. By applying these adjustments, I can easily say that this is overall the best monitor that I’ve used to date. I will not sit here and bash Asus’ most recent iteration of their high refresh rate, 1440p IPS-type display, the PG279QZ, as one can refer to the top review of the PG279QZ to see what types of problems plague those monitors. What I will say is that it’s a breath of fresh air to see that quality control still exists in consumer-grade monitors. Realistically, no manufacturing process is going to produce near perfect monitors all of the time; however, this purchase has instilled confidence in me when it comes to the LG brand. I imagine that this model will provide all disillusioned monitor buyers a glimmer of hope when it comes to having a fighting chance at obtaining a quality monitor in this realm of the market. ***As per a request in the comments, Ive attached pictures of the monitor at brightness of zero, 50%, and 100%. I also managed to track down another monitor from Micro Center, so I posted the same array of shots for this sample too. The results were very similar; however, a small circular area of bleed does exist in the top left corner. It is somewhat noticeable on a black screen unless I increase the height of the stand. To identify the pictures of the second monitor, please see the pictures without the headphones in them. Despite trying several approaches and platforms, the photo uploader refuses to retain the sequence in which I had originally ordered them).***

After doing research for months I settled on this monitor. I had a Viewsonic 32 ink 4k monitor that was just a little to big for my desk and the 4k made writing to small. When I would zoom in or make the print bigger it would get fuzzy around the edges. This Monitor is perfect for my needs. I never thought a higher refresh rating would make that big of a difference but, all I can say is wow. Everything looks so much better. I game at 1440p with an NVidia card and with G-Sync and high refresh this meets everything I could ask for and the price was perfect. Didnt feel to low and therefore a cheap construction product, and not so overly priced and covered with RGB that does nothing but drive the price up. If you want to game at 1440p at 144hz on a budget, please consider this monitor.

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.

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

I upgraded from an Acer ED273 which I had since August 2019. I liked that old monitor well enough - except it had a backlight flickering problem I could never fix. After plenty of research I decided this one was the adequate upgraded replacment. I ordered it as used - like new from a seller, and got what Im pretty sure was more or less a brand-new monitor, with a very good panel at that. Even lighting and very little backlight bleed - a HUGE improvement from the Acer one. I would of course expect that at roughly $150-$200 more expensive. The colors are beautiful - though the reds are somewhat oversaturated. This monitor does tend to overblow most colors, but doesnt really bother me much. Its only red that looks nutso to me! The 144hz refresh rate and 4k resolution are a treat to the eyes. It was easy to set up and feels sturdy - though I am using a third party desk mount arm rather than the stock stand. The VESA mount seems strong and I looove the control stick for navigating the settings menu - the old Acer one had an INFURIATING control stick that, on several occasions, left me wanting to bite the monitor clean in half. I cant even describe how beautiful and responsive this one is compared to the garbage crap on the Acer ED273! I will be updating this review as monitor use progresses over the years to keep up with wear-and-tear and overall lifetime of the device. I know, initially, I am STOKED to have this beauty! I can hardly wait to really sit and play games on it - I only tested some 4k gameplay video in the mean time, which looked amazing!

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.

i use my display a lot both professionally and for recreation. the LG 27GL850-B has some real nice options and color reproduction and brightness, but the IPS panel has some minor bleed you cant get away with and uniformity across the panel has an extreme variation of about 9% from the lower left corner to the middle of the right hand side of the screen. during black moments, this is noticeable, especially in a room without lights, but i keep a dim light on and usually have something on display, so it isnt noticed at all. the swivel adjustment is incredibly stiff and not worth hassling over. the stand is slim and out of the way with a cable keeper that is convenient to tie cables too for tidiness. the screen itself has a non-reflection coating and a bezel about 2.5mm thick which isnt terrible. brightness is over 700 nits (!) which is great if you want a bright screen for movies and stuff. the g-sync module in it works great too, and matches up over displayport perfectly (but not HDMI for some reason). the display is HDR10 capable (10 bit color) and has a gamma of around 2.25. paper white is about 320 nits. the USB ports on the back are at right angles to the display and are easy to get to, but a pain if you have short cables - i would much prefer them on the lower edge of the display like what Dell does. the built-in USB ports are USB 3.1 rated, but you only get two of them. overall very happy with the display!
