This is a 4K display from DELL. I have confirmed its operation and checked for any pixel errors. Please note that the monitor stand is not included. Please use a monitor arm. I am selling it at a low price, so please refrain from returns or refunds. The photos were taken immediately after using a display cleaner, so wipe marks are noticeable, but I believe the screen is clean. The accessories are all shown in the photos, but I will include the AC adapter, the cable cover, and, if you wish, an HDMI cable (standard) for operation check.
