What People Are Saying

Rated 5 out of 5 by from Fantastic Ultra-wide for PC Gaming I’m a proud PC gamer and I purchased the 34” LG 34UC89G-B for its gaming prowess, IPS panel, Gsync support and 2560x1080 resolution which I prefer for games. I’m very happy with it and was pleasantly surprised at the quality for a very reasonable price. I’ve been using the monitor about a month now. I have it paired with an Nvidia GTX 1080 TI using Gsync in all my games. The IPS panel on this monitor is beautiful, giving me great colors with no noticeable light bleed or dead pixels. As far as light-bleed goes, LG seems to have nailed it with this IPS panel. Of course, if I set completely black screen I can see a tiny bit of light at the edges but all LCD monitors have this to some extent and many are much worse. In gaming, working, web surfing I never notice any light bleed or discoloration. I have set the monitor refresh rate to 144hz but I use Gsync in games so refresh rate varies depending on framerate which works great and is really smooth down to the high 30’s fps where the Gysnc module stops varying refresh by design. Also, there is no noticeable motion blur when playing games even with Gsync on or at any framerate. I know the monitor may overclock to 160hz but I see no reason to do this so I haven’t tried it. The monitor has a little white joystick on the bottom of the panel for accessing the settings menu and it’s the best joystick/settings combo I’ve used in a monitor. I set the colors to the high 60’s, the brightness/contrast to the mid 50’s and then used Calibrize free utility to help me with a color calibration profile. There are many options in the settings and also gaming oriented settings; however, I just keep the gaming settings such as overdrive, gamma, etc at default as I think the monitor works great as it is but will have to play with them in the future. I really like the 2560x1080 21:9 ultra-wide resolution this monitor offers because it gives me higher frame rates with ultra-quality settings in games as opposed to lower FPS using higher ultra-wide resolutions (which can double the pixel count at the least) and I hope LG continues to support 2560x1080 in gaming monitors. It’s much easier for me to keep FPS in the high 80’s – 130’s in my games which I really like. The 1080p also means I am not as stressed to replace my GPU as often to keep games at High/Ultra details. Also, Dynamic Super resolution; which GeForce experience can set for you, is much easier on the GPU when calculated from this resolution as opposed to a higher native resolution. The ultra-wide gaming experience is awesome and most new titles support the resolution natively with correct aspect FOV; however, older titles may need mods or tweaks to get resolution support and/or correct aspect FOV, google searches will usually find them. However, if an older title is stubborn with ultra-wide support, you can still turn scaling off in Nvidia drivers and play the game in 16:9 with black bars on the side. The curve on this monitor is very comfortable and doesn’t seem exaggerated at all. The response time is very quick and I don’t notice any lag even in high FPS games like Call of Duty or Battlefield. The monitor was easy to assemble (attach the stand & cable guide) and is fairly light-weight for its size and doesn’t generate lots of heat. The bezels on the side are very thin which is a nice touch. The monitor can adjust vertical, swivel, angle and tilt very easily. I did have to provide a longer Display Port cable as the one provided would not reach my PC which is down on the floor to the side of my desk. The monitor is also a great experience for work and web surfing. The higher pixel pitch makes fonts easy to see and colors look great. As a software developer, I like being able to have my Visual Studio, SQL Server Management Studio in ultra-wide so I can see my code easily and also have other tabs open on the sides. I love this monitor as it is great for gaming, is a curved ultra-wide, supports Gsync, has a high-quality IPS panel and the 2560x1080 resolution is also less stressful on my GPU.

Rated 5 out of 5 by from Simply Amazing I've been using this monitor with a Nvidia Titan Xp for about a week now and it's simply breathtaking. Such and incredible improvement over my 4-year-old previous set up. My panel has no dead pixels, and barely perceptible backlight bleed so I'm very satisfied. The colors are stunning on this monitor as well and the size and curve is incredibly immersive. I love it.

Rated 2 out of 5 by from Meh 5ms response time is just too high for me to be interested when I currently have a monitor with a 1ms response time. You're also going to want to take into consideration you need a pretty good GPU setup in order to use this monitor to it's fullest extent. If you play games like PUBG regularly, do not buy this unless you've got at least one 1080ti to make it worth your while. Otherwise you'll just be losing insane amounts of frames and playing your game in a small window (in comparison to the size of the monitor) to maximize the frames you'll be able reach. However, if you're not really into GPU heavy shooters, or like games similar to Nier Automata or Metro: Last Light, this monitor is not a bad deal. But in all honesty, I'd spend a little extra money and get a 4k if that's what you're in to.

Rated 1 out of 5 by from Worst Monitor Ever I just purchased it on Cyber Monday, 2017. It lasted all of 16 hours before it, for a lack of a better word, died. My other monitor of 4 years works fine but this absolutely brand new monitor just died.

Rated 5 out of 5 by from High five LG! I have had my eye on this monitor for weeks now and I finally dropped the cash on one (Not lucky enough to be one of the YouTubers who got given them!) and I am so happy that I did. The only worry I had with this monitor was the resolution but I comfortably can say that it isn't an issue. I even sold my 4K LG27UD88-W to put towards this so it was a big drop in resolution.  This display is clean looking, colourful and fast. I had never experienced ultrawide, G-Sync or a refresh rate faster than 60Hz and I have been blown away by how good these features are. All the games I play are 21:9 supported and my 980Ti is running them on ultra settings between 90 and 100FPS. Had the resolution been 2560x1440 it would have been difficult to get frame rates as high and all the competing monitors at that resolution look ugly/gamery, have terrible quality control issues and are pricey in Australia. Even browsing the internet and watching 21:9 video content is good on this, the extra screen space is so nice to have. I have used dual set ups before and it is so nice to not have the bezel between them. I honestly could go on and on about how much I enjoy using this monitor. For anyone who is concerned about the resolution, don't be. If you have huge amounts of cash to burn for a system (and the monitor) that can run a higher resolution at higher refresh rates then it might not be the right choice. But for anyone who isn't in that tier, build your PC around this monitor. It is amazing!

I'm looking for the best full 4k monitor dedicated to my Xbox one X. Can u help me

Asked by: Half hands
There aren't any monitors that are dedicated to any one particular gaming console, but currently, the LG 32" Class 4K UHD IPS LED Monitor with HDR10 (31.5" Diagonal), Model # 32UD99-W would be the best monitor as it features a resolution of 4K UHD (3840 x 2160), it supports HDR10 and also supports AMD FreeSync™ Technology over HDMI, has an ultra-thin bezel—a mere 1.3mm—on four sides of this streamlined display which offers a virtually borderless visual experience.

I am looking for two curved screens apprx. 32-34" and a stand that permit the monitors to be rotated so that they are back to back instead of both facing the same way.
