Review on Dell U2720QM UltraSharp Ultra Thin DisplayPort 60Hz: A High-Performance 4K Monitor by Todd Zimmer

I'm an educator so we're having a very busy time of the year right now. Excited about my first 4K monitor with a USB-C port, I was dying to use it. It arrived in early August and was in use for about 2 weeks - it worked perfectly. It's August 19th. I have "ghostly" images flickering on my screen in the background. I've rebooted, changed all cables, even tried a regular displayport - to no avail. I was looking for this specific problem and it was a problem for several people. This shouldn't happen with a new monitor. Luckily I'm within the return window but damn I'm furious. Listen to the negative reviews - I would love to.
