DisplayPort No signal

techjunkie92

This morning my second monitor that is connected via DisplayPort started saying 'no signal".  Tried unplugging cables, powering on and off etc.  I went into the bios and made sure multiple display setting on the CPU was enabled. I made sure my bios was updated, made sure my drivers were updated.  I went into windows and put my power mode on high performance because I've read that this sometimes helps, no help.  I plugged in an HDMI cable to trouble shoot.  HDMI works and when I have an HDMI and DisplayPort cable both plugged into my graphics card the monitor works with DisplayPort, but my computer recognizes three monitors.  I have it working with HDMI at the moment but I would prefer to use DisplayPort.  Only thing I haven't tried is a new cable because I didn't have one lying around.  I recently upgraded to windows 10 so I thought this could be a possible problem but it just started today and I've had Windows 10 for a few days now.  

 

Hardware

 

2 Asus VG248QE

MSI GTX 970

MSI z97 Gaming motherboard

 

Any possible solutions would be much appreciated on this, has me stumped and a little frustrated at the moment.

 

Thanks.

made sure your monitor is on DP mode not HDMI? 

 

idk man, try a new cable, sounds like you covered most of the bases.

We can't Benchmark like we used to, but we have our ways. One trick is to shove more GPUs in your computer. Like the time I needed to NV-Link, because I needed a higher HeavenBench score, so I did an SLI, which is what they called NV-Link back in the day. So, I decided to put two GPUs in my computer, which was the style at the time. Now, to add another GPU to your computer, costs a new PSU. Now in those days PSUs said OCZ on them, "Gimme 750W OCZs for an SLI" you'd say. Now where were we? Oh yeah, the important thing was that I had two GPUs in my rig, which was the style at the time! They didn't have RGB PSUs at the time, because of the war. The only thing you could get was those big green ones.

It auto detects the mode and I had it set.  Must be the cable.  Ordering new ones to see if that hopefully fixes it.

Does your monitor have a setting to switch between different versions of the DisplayPort standard? My old troublesome Dell U2414H had this issue where the monitor would not display the signal when set to DisplayPort 1.2.

Another possibility could be the driver Windows is using for your monitor(s). I have a Dell U2415 here and I tried installing the specialised monitor driver from Dell's site; it started blanking out at times afterwards and I reverted to the generic Windows driver for it.

Another thing would be your monitor somehow not receiving any signal after you updated your BIOS. Happened to me after I updated my BIOS firmware just now; power-cycling the monitor using the power button brought it back to life for me.

It doesn't use multiple DisplayPort that i'm aware of.  Bios was updated after the issue had occured and power cycling doesnt fix it.  I installed the driver from ASUS after the issue to see if that would fix it but no luck there either.
