**What is your parts list? [Consider formatting your parts list.]
Describe your problem. List any error messages and symptoms. Be descriptive.
A few nights ago I was playing a game for an hour and went to bed. After work the next day I turned my PC on and it booted correctly, but my monitor (ASUS VG248QE) said «DisplayPort — No Signal» on it. My TV is also plugged into the GPU via HDMI and it works fine. When I unplug the HDMI from my GPU (MSI GeForce GTX 970 Gaming 4G), my monitor detects DisplayPort again and begins working. My monitor also works when using HDMI from the GPU.
List anything you’ve done in attempt to diagnose or fix the problem.
I tried another DisplayPort cable, no change.
My friend has the same monitor so we tried it on my PC with my cables and it worked. (This confirms my cables and GPU are fine.)
I then tried my monitor on his PC with his cables and it worked. (This confirms my monitor is fine.)
My monitor works on my motherboard ports, and also with HDMI from the GPU. DisplayPort from my GPU is the only input that doesn’t work from my computer.
I did a clean reinstall of the latest Nvidia drivers 4 times, no change.
Did a clean install of previous Nvidia drivers that I know worked before, no change.
Updated all the rest of my drivers and BIOS, no change.
Did all recent Windows updates, no change.
Tried to do a System Restore to a point before the issue occurred but it failed.
Tried the ASUS trick of unplugging the monitor from power for a few minutes and plugging it back in, no change.
Power Settings set from Balanced to High Performance, no change.
Post relevant photos of build/parts here.
I’m a certified PC technician and am 100% sure that everything is plugged in and installed correctly as it has worked for over a year prior to this, so I’m not going to invest time in taking pictures.
Provide any additional details you wish below.
As I said above, this issue only occurs when plugging a secondary monitor into the HDMI on my GPU. As soon as the HDMI is unplugged, my monitor can detect DisplayPort again.
I called ASUS and they insist that my monitor is defective, which I have ruled out by using it on my friend’s PC.
I have found hundreds of people posting with the same issue online and many of them have never found a fix. I have tried every fix that I’ve come across and nothing has worked.
I would like to try update the vBIOS on my GPU but haven’t found a source for the latest version.
I have read multiple forums online of people that have tried formatting Windows and it hasn’t helped. I would like to avoid this method if possible as it would be a lot of work for what seems like an unsuccessful method.
Any tips or advice would be GREATLY appreciated as I have easily spent over 20 hours trying to resolve this!
No DisplayPort signal from your device? 10 Ways to Fix
1. Disconnect and reconnect the DisplayPort cable.
If your DisplayPort monitor does not detect a signal from your computer, unplug the cable and plug it back in. Make sure your PC’s DisplayPort port is clean and free of dirt and dust before reconnecting the cable. Also, make sure that there are no obstacles between the cable, the computer, and the DisplayPort monitor to come into contact with foreign materials.
Use a can of compressed air to remove foreign objects from the DisplayPort connector on the monitor and computer. If your computer uses a DisplayPort adapter, make sure the cable is properly connected to the adapter and the adapter is connected to the computer. Switch the cable to a different DisplayPort if the adapter has more than one port.
2. Install monitor drivers
Some external monitors have built-in drivers that control certain components or functions of the device. If your monitor requires you to install a driver or a companion application, be sure to do so. Otherwise, the monitor may not detect the DisplayPort signal from your device. Refer to your monitor’s instruction manual or contact the manufacturer to see if a support driver or application is required for the device to function properly.
3. Select the correct input source
For monitors with more than one DisplayPort, make sure you use the menu to select the correct active input source to which you have connected the DisplayPort cable. Let’s say the monitor has two DisplayPort ports, «DP1» and «DP2». Make sure the monitor’s input source is set to «DP1» if your computer is connected to the first DisplayPort, or «DP2» for another DisplayPort.
