Hello, bought a Dell U2415 monitor a few weekends ago. I use it with my MacBook Pro and a Lenovo laptop from work through HDMI cables. Randomly, today, I turned the monitor on like usual and it just had a bunch of green dots that flickered on and off, on and off (from green to purple, back to green) then it just flickers off entirely after a few minutes. What is going on???? It does the same thing whether or not I have it connected to a computer. Any help would be much appreciated before I return it. I just can't find anything online like this.

* From Dell or some reseller?
* What is the 20 digit serial number and A0x revision?
The video you linked does not play for me. States, "This plugin is not supported".
Take both computers and cabling out of the troubleshooting equation. Show us pictures of the issue when running the U2415 standalone "Built-in Diagnostics", page 58.
