Clearer, Smoother Image

With AMD FreeSync™ Technology, gamers can experience seamless, fluid movement during hi-res, fast-paced games. Free-Sync virtually eliminate screen tearing and stuttering.

Enemies have Nowhere to Hide

Maintain visibility, even in dark scenes. Black Stabilizer detects low-light situations and increases your display’s brightness to help you find any hidden enemies waiting to attack your player.

Better Aim

The Crosshair feature lets gamers take their skills to the next level. The striking point in the center of the display offers better firing accuracy for first-person shooter games.

*FreeSync is only available when it is connected to Display Port or HDMI.

What people are saying

Rated 5 out of 5 by from Best monitor ever I decided to upgrade my monitor size due to my continued work from home status and this monitor did not disappoint. The size, clarity and overall appearance makes my workday that much more effective. The sound is also top notch. Highly recommend.

Rated 4 out of 5 by from Great wide screen for office While searching for a 34 wide screen, I read lots of comments saying that 34wk650-w was not a good screen for office tasks, they recommended it to game and movies, but not for office. I decided to take the chance despite the negative comments because the cost benefit (34in for less than than $400). Let me tell you that, the monitor is perfect, I do not perceive any of the resolution problems people reported regarding this screen, it is not a 4K and I do a lot of spread sheets, text and web and I am really happy with that. The speakers are not the best I ever heard, but for lectures and YouTube it works well. The only negative aspect I have to point, is regarding the power cable, often times the screen goes off for a sec or two and comes back. I already checked all the cables and they seems to be in order, my next step will be to contact the warranty/support and ask for help, perhaps it is settings problem instead hardware.

Why can't I set the resolution to 2560x1080 on my Macbook Air running MacOS Mojave version 10.14.6 (18G8022)? The only resolution I got to choose from is 1080p. A mini-Display to HDMI cable is used.

Asked by: Anonymous
The LG 34'' Class 21:9 UltraWide® Full HD IPS LED Monitor with HDR 10 (34'' Diagonal), Model # 34WK650-W has a native resolution of 2560 x 1080 which is an Aspect Ratio of 21:9. You cannot change the native resolution on the monitor. You have to access the Display Settings in your MacBook Air to change the resolution that your GPU should output to match what is supported on the monitor. The GPU in your MacBook Air may not support 2560 x 1080 which why you are only getting 1920 x 1080 which is a 16:9 Aspect Ratio. If your GPU supports 2560 x 1080, it would appear in the drop list of selectable resolutions. Check the specifications for the GPU in your MacBook Air to see what resolutions it supports. You can contact Apple to see if you can customize the resolution by clicking the scaled option...^IFV

Is it good for colour grading?

Asked by: Jake03
That depends on what your criteria are for a monitor that meets your needs for color grading as a videographer or photographer that engages in color grading with a high-end system and viewing your work from a different angle. You will need to consider the Screen Size. The screen size you go for depends on how much room you have to accommodate suitable viewing distances. The Type of Panel. For color grading, you need a monitor with IPS LCD panels—as it gives a better viewing angle and supports pro color spaces. HDR Support. You need HDR on a monitor because it increases the color intensity and contrast of your images to a brilliant degree. Color Support. Monitors with a wide color gamut like Adobe RGB, DCI-P3, and Rec.2020 are ideal because they offer exponentially finer color detail compared to older standards. Thus, it’s advisable to opt for 10-bit color—to increase dynamic range.

Followup question: the 34wk65w has no PBP according to specs. Can it still display two computers on the same monitor simultaneously(split view) without PBP? And can you transfer files btwn computers with dual controller?

Asked by: Andrew9
I have tried the onscreen control software on my main PC and split into two and it didnt bring up my second PC which is running as Sub-PC on dual controller. On screen control is giving to split the main PC image into two or more depending on what we choose and will not add the second external input source to the main image. Please fix this issue.

The specs say this monitor has dual controller but lacks PBP.  What can you do with dual controller without having PBP?  I want to connect two different computers to this monitor, be able to control both computers with one input device and transfer files.

Asked by: Andrew9
The Dual Controller software can be downloaded and installed from the support page for the LG 34" Class 21:9 UltraWide® Full HD IPS LED Monitor with HDR 10 (34" Diagonal), Model # 34WK650-P.
