What people are saying

Rated 2 out of 5 by from USB A is not recognized by latest Windows 10 Just bought new one this week. Connected USB A to computer, and Windows 10 indicates the USB device not recognized. Search online, and find out this is issue related to multiple LG monitors and no fix.

Rated 5 out of 5 by from Flatscreen Ultra-wide Heaven! The flat screen and connectivity features of the LG 34WN750-B comprise the perfect fit for my needs. Photo editing, Video editing and music mixing confirm this was the right choice. The performance and design have exceeded my expectations proving LG was the best choice for my budget. I couldn't be happier.

Rated 4 out of 5 by from Great price/performance I upgraded to this from 2 27" 1080p monitors -- I lost a bit of screen real estate, but it was well worth the switch. This is the first IPS panel I've owned, and the color depth and viewing angles are absolutely amazing The only downside is that HDR10 and Freesync do no play well together -- with both enabled there is noticeable gradient banding, especially over dark backgrounds; but after searching around online it appears to be an issue with the spec, not this monitor After receiving this monitor I had some issues with power delivery -- the monitor would switch to a white static snow and become unresponsive until power-cycled. I RMA'd the monitor and LG was able to repair and send it back to me in a very timely manner, especially given the nightmare shipping was at the time with the pandemic.

Is it possible to connect two of these LG 34WN750-B monitors together (daisy chain options?)

Asked by: s7i4n
Hello, s7i4n! Good question! The 34'' 21:9 WQHD IPS HDR10 Monitor with FreeSync (34WN750-B) only has 2 x HDMI inputs & a DisplayPort input. It does not support daisy chaining. HDMI ports do not support daisy chaining and you need a DisplayPort output to connect to a DisplayPort input for daisy chaining. ^Jolly

Screen is few months old and it's blinking to a black screen randomly throughout the day. It only stays black for a second or two. What is happening? The input cords are secure and my other monitor isn't blinking? Connected to Macbook M1 processor

Asked by: Linz22222
Other than faulty, damaged cables or ports causing the screen for the LG 34'' 21:9 WQHD IPS HDR10 Monitor with FreeSync, Model # 34WN750-B randomly going black for a second, a simple problem with the power settings might also cause your monitor to black off randomly. So, you should verify that Energy Saving mode or a screen saver is not enabled on your device. It could also be caused by a display driver issue or an incompatible app. To determine whether an app or driver is causing the problem, check to see if Task Manager flickers. Then, based on that information, you'll need to either update the app or the display driver. You may also want to check that the refresh rate is not low...^Ivan

Can I connect from my Macbook pro using a thunderbolt to HDMI cord?

Asked by: Anonymous
You will need an appropriate conversion cable or an appropriate adapter if you are looking to connect to the HDMI ports on the LG 34'' 21:9 WQHD IPS HDR10 Monitor with FreeSync, Model # 34WN750-B. If your MacBook Pro only has a Thunderbolt port, then you will need to use either a ThunderBolt to HDMI cable or an adapter that lets you connect a Thunderbolt port to an HDMI port. The HDMI ports on the monitor are both HDMI 2.0 ports and they are both HDCP 2.2 compliant...^IFV
