Review on ViewSonic VP3268A 4K Ergonomic DisplayPort Professional Monitor, 3840X2160P Resolution, Cable Lock Slot, Anti-Glare, 3H Surface Hardness, On-Screen Display (OSD), ‎VP3268A-4K, HDMI, HD, 4K by Todd Mracek

Update 10/12/2022: After checking the model on the manufacturer's website, I found that the device has a really good manufacturer's guarantee. I had to pay $30 to ship the monitor to them but they fixed the hardware fault and sent it back and no problem since. Update: Out of the box, one of the monitors flickered on and off very sporadically, but I figured there was a problem with my old laptop's docking station. Last week I got a new laptop with a new docking station. Today my monitor, which turns on and off intermittently, went black and won't turn on. The power button light comes on and changes from blue to orange depending on whether it's active, but nothing shows up on the monitor. Expensive monitors in just 2 years of use and that's a failure. Otherwise I like the monitor as a whole.
