I have a one year old 8920 XPS. I have dual monitors (Dell UP2414Q and Dell P2415Q) connected via the display ports, and a NVIDIA GeForce GTX 1060 with 6GB GDDR5. When I turn my computer on, often times my main monitor (UP2414Q) acts like it is in standby or sleep mode and fails to turn on properly. I usually just see the black screen. I turn the monitor on and off, which sometimes does the trick. More often I have to restart. Usually this happens 4/5 times I turn my computer on or restart it. Also, while I'm using my computer, it regularly goes into a black screen (the display port icon will show up on the UP2414Q in the top right corner), and then it will usually come back on in 2-20 seconds. Sometimes it will display a message, such as referring to standby mode. Sometimes when I turn my computer on, like today, neither monitor loaded properly and I just had a black screen on both of them, forcing me to restart. I have run all of the diagnostic tests (including on the graphics card) and they say everything is working fine. All of my drivers are up to date. I've reset the settings too and still have the same issues. Please help.
