Review on Dell P2721Q Ultra Thin DisplayPort Certified 4K 3840x2160P Monitor with 🖥️ Flicker-Free Technology and Multi-Adjustment Stand, USB-C Connectivity - Dell 27 4K Monitor by Sean Fatherofgods

Less than a year later, the USB-C port stopped working with the display, so I started using the displayport, which continued to work for a few months until part of the screen got stuck on the previous image. The stuck image flickers no matter what device and port I'm using. basically useless now. Absolutely disappointing as it is more expensive than other monitors I have that still work well after many years.
