So I purchased a new monitor today and set it up and it works perfectly fine, BUT, my old monitor that also ran on DP no longer is detected. I'm using the same DP cable i was using before, I've tried a different one, I've tried the "unplug it for 1 minute to reset" thing and it doesn't work. I've updated graphic drivers and restarted and still nothing. I'm at a loss and I figure it's an easy fix somehow, but I just can't seem to find it.

Monitor: Acer K272HUL
GPU: MSI GTX 980

So, I have found the answer to my problem, AND, like I said, it was the stupidest reason...

So I decided to look at the input on the monitor in case i did messed it up some how and in doing so...noticed another DP input...which was the correct one to use. I'm so frustrated with my ineptitude, but am very grateful for ALL the help you have provided. :)

This will sound strange but do this anyways. Power off computer, hit power supply switch, take monitor turn it off and unplug it from power source, wait about 30 seconds, plug it back in and turn PC back on. Display port should work again. Its like a switch. your monitor will retain a setting and sometimes get stuck. DO in that order

When troubleshooting problems its always best to do it in its most simplistic form. If you have two monitors currently plugged in. try to get the old monitor up and detected solely first.

I've had a multi-monitor setup the whole time. I've just changed 1 monitor from a dvi to DP, but my ORIGINAL DP monitor won't register anymore with DP.

I've gotten it to be detected with DVI, but it still doesn't explain why it would stop.

Hmm.. typically these problems with display port is just not being securely plugged in, or the power cycle usually fixes.... you aren't daisy chaining connections you are doing dp to dp on PC, and dvi also to pc. Idk man im confused lol

HDMI works. Text and stuff is clear too. Still just baffled why DP doesn't work anymore. I've tried doing the power cycle again and using a different cable and having it be the only monitor, but wouldn't come up.
