I'm using 144Hz over HDMI 2.0 with my RTX 2060 and 2 other monitors, works great! I didn't test 144Hz over Displayport with a regular cable as I didn't have one, but 144Hz didn't work with the Displayport to HDMI cable I had. So if it doesn't work, try a different cable. Also check the windows display settings, but when I connected to HDMI it automatically detected 144Hz. The VESA mount is good, although the stand looked good too. It's very bright so I only use 20% to match my other monitors. You can change the preset modes and switch between them pretty quickly, so that's also a nice feature that I'll end up using. You can mute the speakers directly from the monitor menu, but that will likely mess up your windows settings, so replace them with regular speakers once you connect the monitor. The power button and all controls are on the right side behind the screen, so having another monitor on that right side is a little annoying, so keep that in mind. There's a very small raised bezel on three sides of just around 2mm, then a 6mm bezel that sits flush with the screen. This makes it look very good compared to my other monitors with thick bezels of 15mm and up, and the screen is recessed into the bezel by 5-6mm.
