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.

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.
