New ASUS ROG PG279Q Not Displaying

[llysanth]

I just built a new Gaming Desktop. Been a bit since I have, but I am certain everything is compatible. Everything is new from the case, monitor, keyboard & mouse, and all the way up. I got it all together today and the monitor is telling me that there is no Displayport Signal. Any help would be appreciated, as I am unable to even install Windows 10 or get to the BIOS with no display. Thank you ahead of time.

Does another monitor work? Also, try another DP cable.

I tried 3 different monitors and none worked seeing as though the monitor is capable of Display Port, HDMI, and DVI-D. I did hook the monitor up to a computer that had Windows 10 and it did work instantly. After racking my brain for 2 days, just as I had hoped it would be, it turned out to be something simple. What I had done was remembered the light on the motherboard can indicate errors besides the digital display of numbers and letters. Once I checked it, it turned out to be yellow which indicates that there was an DRAM error. After reseating all of the sticks, unplugging, powering down and powering back on one at a time, they all worked and my computer started as intended, monitor and all. So, in that, thank you for you help and I hope I did not waste too much of your time.
