Working great as a second monitor
My main monitor is a LG 32” 4K 144hz which I got for around $700 a few years back. I know OLED is the lates and greatest but I needed IPS for the viewing angles and because I leave my PC on 24/7 and game for hours. It’s worked flawlessly so when I wanted to pick up a second monitor I decided to keep it to the LG line and this one is like a baby brother of my main monitor, just at 1440p. Colors look great after adjustment, no dead pixels, no extreme IPS glow.The only con is the round back design LG likes to do with their UltraGear line. You won’t be able to add a monitor bar with it. Also, the original stand has very limited adjustments, but if you’re using a third-party arm like me it’s not an issue. One other thing to note; when you remove the OEM stand, there’s a little mounting piece that kind of just sticks out from the back.Other than that, this is a quality monitor. Admittedly I haven’t done hardcore gaming on this since I’m using it as a second monitor but the quick testing I did was great. Definitely recommend this especially if you can grab it at around $200. Great value.

Amazing Montor for Amazing Price
I purchased this monitor because it looked like it had good specs, and I really needed an upgrade.As I used it, it was everything I expected and more. For the price, you can't beat the 2k gaming quality that it allows you to play at.The monitor feels really high quality, allows me to play at 144 herts, and is a massive upgrade especially if you are still on 60 herts. You can change many things like the color, brightness, and so much more like putting a cross hair on the screen.If you are looking for something similar to this monitor or even considering getting this one, definitly do it.

I might be biased but this monitor is amazing!
I had been looking at two different monitors and I finally decided on this LG Ultra Gear monitor. I have to say coming from a very old monitor (with VGA and DVI) I am beyond impressed with this monitor. It's a steal, I got it on sale for $346.99. The brightness is higher than I expected and the menu is beyond easy. Just so everyone knows I used this with my Xbox Series S and it was fully compatible with AMD Freesync Premium and 1440p 120fps. I don't know if it's the Xbox or the monitor but if you have HDR enabled your framerate drops to 60fps which is fine with me cause the only time I would use HDR is with movies. The only downsides are quality control. Backlight bleed and dead and/or stuck pixel are relatively common and multiple people have had reviews on this monitor saying it has a dead pixel or severe backlight bleed out of the box. I had no dead pixels and a very VERY tiny amount of backlight bleed at the top. I don't know if I'm lucky or if they just fixed some production errors. I also was missing an HDMI cable that comes with it. All in all very happy with this monitor and would recommend to anyone in the price range.

Top-Rated 2560 x 1440 Monitor is Fantastic Despite Missing Flex Joints
I've read reviews here complaining about stuck and dead pixels and other image oddities with this monitor, and either I'm unusally lucky and they're really unlucky, or this is just a great monitor that got jumbled around for some people in shipping - because for the last 2+ months the picture has been flawless and jaw-dropping in its clarity and contrast.I picked this monitor after my old 24" Dell developed a weird, intermittent power-socket problem that had it shutting down whenever so much as a house fly would land on the cord. I took it apart to inspect the socket's solder joints to the PCB and they were solid, which led me to believe it was an issue with the power supply circuit itself, likely a failing cap or something. But after using that thing for close to a decade it was time for an upgrade anyhow.So I did some well-spent time scouring a whole bunch of online "Best of" review pages for 27" 2560 x1440 monitors, and when it finally came down to a toss-up between this LG Ultragear and a Gigabyte M27Q this one won, mostly for being almost 73 bucks cheaper. The Gigabyte has a slightly faster refresh rate - 170Hz vs 144Hz, and a 0.5mS response time rather than 1mS, but I'm not a heavy-duty gamer running a mega-overclocked $4k gaming PC with a graphics card that costs as much as my whole system, so those weren't persuasive enough to get me to part with the $73 extra - and I'm thinking even hardcore gamers would be hard-pressed to spot any appreciable difference between the two. So LG Ultragear it is.The biggest downside is that there is exactly one (1) physical adjustment that this monitor's stand allows, and that's: Tilt. It's a fixed height so no up-down at all; there's no rotation joint for landscape/portrait orientation like the old Dell had (but not something I ever used anyway,) but there isn't even a side-to-side rotation joint on the base. That last is inexplicable and an annoyance because it's a useful adjustment especially when you have a small and cramped desktop, but given the otherwise-flawless nature of this product I can deal with it. *And* it looks really, really cool, with the red-and-black color scheme on the reverse side - if that's visible in the room where you're using it.The only other problem I had was that I could not get the HDMI ports to work with my graphics card (an AMD,) so I had to go buy a DP cable that would reach. That may be a glitch with the graphics card rather than the monitor, so I give the benefit of the doubt on that one. But once connectivity was out of the way, no problems.I've been using this for just under three months with no issues and continued amazement at the image quality and contrast. So if you're looking for a truly great 27" monitor that has some impressive technical specs for the price, buy with confidence. If you're feeling flush, go have a look at the similarly high-rated Gigabyte M27Q - Amazon product code B08JWCHR5N. But at $277 you can't beat this LG. Happy camper here.
