Hi there,
I just bought this monitor and got a pretty good Warehouse deal on Amazon. However, the display seems not to work correctly. It has these strange flickering pattern on the left side. Intensity varies, depending on how many Hz I set and on the application I use. At first I thought it could be related to the cable because I don't use the ones which came with the monitor. LG only delivered DP-DP and HDMI-HDMI. Since the monitor is connected to a MacBook Pro M1 Pro, I needed to buy a DP-USBC cable. The cable is of good quality and can do 4k at 120/144 Hz. I even bought another one from a different manufacturer, but the same problem. I did a bunch of tests and I am pretty sure it must be the monitor. However, as I am not a hardware expert, I thought it would be a good idea to ask some people who have some expertise before sending it back.
