Ease of Use:


  • Nice monitor but don't assume!!
    Verified BuyerReviewed by Jeff - January 15, 2021

    The monitor itself but don't assume it does what you think it does...it has a very good picture and the speakers that are built in are actually not bad at all. The stand is built very well and is sturdy and the remote was a nice addition to the monitor. The monitor has multiple inputs from multiple computers and the ability to split those separate computers.....BUT what it does not do well is easily allow the splitting up of 1 computer with 4 programs which is what it appears like your seeing in the photos but that's either 4 computers or it took a while to place those programs into position for the photo session. It's also not worth the price tag for this one.

    Ease of Use:

  • Quad 1080p monitors without the bezel.
    Reviewed by TriAxis - December 11, 2020

    I bought this to have 4 monitors without having an ugly black bezel in between each one. I use the bottom 2 monitors for work, and the top 2 monitors for Netflix or Amazon fire stick. I usually stream the same video on both top monitors at the same time. This LG allows you to use the same source on 1 up to 4 quadrants. The remote has an audio input selection so you can control which input audio plays. When I am not working I will switch to 1 source and watch shows in 4K and the monitor become a large TV. I have used it for over 7 months daily and no issues. I wish it had a Webcam built in, but that is my only complaint.

  • Dream Come True
    Reviewed by JGonzalez - February 8, 2021

    This monitor has solved many problems for me after having started working remotely. As a programmer, I desperately needed more screen real estate. This monitor offers me more than enough needed to efficiently get my work done. And I won't lie: it's been great for gaming, too. For dev'ers out there I recommend setting res to 3840 x 2160, scaled to 125 - 150%. The speakers are a very nice touch as well! I love that this comes with a remote control so I don't have fiddle with tiny hard-to-use toggles. I have run into issues with downstreaming the USB ports, but I suspect this just might be an issue with my laptop.
