What people are saying

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.

Rated 4 out of 5 by from Ultra wide ultra cool I have been using the LG 34 inch ultra use QHD for a couple weeks now and think this a good monitor to use for gaming. I hooked up the monitor to my gaming system and some of the action games were really crisp. The motion resolution was good and could be adjusted to what I feel was a good speed to capture the game I was playing. Picture Mode was great as I was able to switch to Cinema effects for movies while also having a color weakness control for people with issues seeing colors. All eight of these picture modes gives the person ultimate control for best picture resolution. The aspect ratio control was cool as I was able to go between full widescreen and cinema. Clarity was very exceptional in cinema mode.Was really easy to set up with just an HDMI cord plugged into the back. The monitor came with limited directions in the box but did provide a useful website. I eventually found out how to navigate through the monitor as their is a toggle switch underneath the screen which allows me to control volume and HDMI inputs. That part took a little getting use to as the switch is small. I would almost prefer a remote control to the little toggle switch. Once that was figured out, it was somewhat easy to navigate the controls of the monitor and get the ideal picture. The sound was ok and seemed loud at times and did not project all over the room to well. I liked the width of the screen. Was really able to capture a lot when gaming. The monitor was easy to put together as their is a nice solid base that the monitor sits on. The monitor also tilts up or down depending on what somebody might be comfortable with. I also hooked up my Blu-ray player to the monitor and was able to get a good resolution. I would recommend this LG monitor as it provides good picture for gaming and the sound is above average. "I received this product at a discounted price in exchange for my honest review".

Rated 5 out of 5 by from Great Monitor I have been interested in upgrading to an ultrawide monitor for a while. I was not sure how much of a difference upgrading from a 24”monitor would be, but I have been very impressed so far with the LG 34WN750-B . I have been using the monitor mostly for work, and a little gaming and it has a great clear picture and refresh rate that seems to keep it flicker free, and the amount of screen space is amazing. The LG 34WN750-B is easy to install, and it come with HDMI cables making it ready to go right out of the box. You just have to unpack it, plug it in the supplied cable, and you are up and running in less than 5 minutes. Using just the hdmi cable to have video and audio on a monitor is one of the features I think makes it stand out from other monitors I have used. I have been using it for a week now, and I have been very impressed. The size is unbelievable, and is almost the width of my desk. I love the wide screen, and I was not expecting speakers built into a monitor, but this is a definite plus. Overall, this is a great monitor if you are looking to upgrade, and I would definitely recommend it.

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.
