Windows 10: After updating Windows 10 my DisplayPort randomly has no signal

This has happened before and I just assumed it was the cable, but this is a brand new cable and was working perfectly fine up until randomly this morning when I was forced to update.

Windows 10 unstable in dual screen setup displayport + hdmi

I just changed my system from an intel i5 2500k to an amd r5 1600 and with almost the same hardware (only changed cpu, motherboard, ram and switched to a m2 ssd as windows drive) and windows version (freshly
resinstalled) windows crashes when I turn my displayport screen on again in dual screen setup with an hdmi screen.

System Configuration:

Motherboard: MSI X370 gaming pro carbon

BIOS: 7A32v17 (AGESA 1.0.0.6)

CPU: AMD Ryzen 5 1600

Memory: 16GB DDR4 3200 (G-Skill F4-3200C16D-16GVKB)

GPU: MSI RX 480 gaming x 8GB

VBIOS: 015.050.000.000

GPU Driver: 17.7.1

OS: Windows 10 Pro N x64 (15063.483)

Steps to Reproduce:

• 
  Plug into gpu ports: BenQ XL2730Z @ displayport, Philips 273P3LPHES @ hdmi
  
• 
  turn on pc and displays, wait for windows login
  
• 
  turn off displayport display
  
• 
  turn on displayport display
  
• 
  what now happens: displayport display stays black (no signal), hdmi display turns black (no signal), pc unresponsive
  
• 
  after 10 - 20 seconds pc reboots automatically
  

Expected Behavior:

displayport display should turn on normally without crashing the pc in dual screen setup

Actual Behavior:

displayport display causes crash when turned on again

Additional Observations:

Turning the hdmi monitor off and on does not crash windows even if displayport display is plugged in.

Unplugging the hdmi monitor and turning the displayport monitor off and on does not crash windows.

I used the exact same hardware and drivers before with an Intel i5-2500k and an Asrock Extreme 3 gen 3 without these issues. Windows and drivers were completely reinstalled though after switching to Ryzen.

Monitor is not working with DisplayPort to HDMI adapter

I have a HP EliteDisplay E222 and it is not able to recieve signals using a HDMI to DisplayPort adapter. I have tried plugging in the DisplayPort side of the adapter into my computer and into my graphics card and both of them give me no signal and that makes
me think it is the monitors issue. However, when I plug the current monitor I am using into the HDMI side of the adapter (when the DisplayPort side of the adapter is connected to my computer) I also get no signal.

I have confirmed that the adapter works on my other computer but I just can not find out why it is not working on my main one.

I have tried:

1. Letting windows pick graphic card drivers (RX 570)
2. Installing the latest drivers
3. Taking the power cable out of my second monitor for one minute
4. Resetting the monitor
5. Turning off the power saving setting in the monitor
6. Turning power mode to high performance in Windows 10

Unfortunately my current monitor has no DisplayPort port. If it did, I could of connected the DisplayPort side of the adapter to it to determine if the graphic card is the problem or if the monitor is.

 

displayport no signal

Hi Jason,

Please check these suggested steps on how to troubleshoot your current issue:

1: Ensure your compatible video cable is firmly connected

A loose connection between your monitor and your PC will trigger the monitor no signal issue. If you’re seeing the no signal message on your screen when your Windows system is running, the first thing you should check is whether your compatible video cable
is firmly connected or not.

2: Check if you selected the correct input source

If your didn’t select the correct input source for your monitor, you will also get the monitor no signal issue. Before you select the correct input source for your monitor, you need to know what ports your PC and the monitor have.

DP, HDMI, DVI, VGA

Follow the instructions below to select the correct input source for your monitor:

Ensure your PC and your monitor are both turned on.

Press the menu button on the edge of your monitor.

Navigate to Input Source and select the correct input source. For example, if you connect your monitor to the VGA port on your PC, then set the input source as VGA.

3: Check if your graphics card is firmly inserted in its slot

You will also get the no signal message if your graphics card is not firmly inserted in its slot. In this case, you need to open your computer case to check. Here is how to do it:

1) Turn off your computer, then disconnect all the cables (including your power cord) and the attached devices from your computer.

2) Open your computer case to locate your graphics card.

The exact location of the graphics card depends on the type of card in your computer. If you’re not sure, please consult your PC manufacturer for assistance.

3) Remove your graphics card from your motherboard and then insert it firmly in its slot.

4) Plug the power cable of your monitor back in and connect it to your PC.

5) Hold the power button down for 30 seconds to a minute and then connect your power cord back and turn it on.

4: Test with another cable or PC

The monitor no signal issue is also probably caused by a damaged video cable. Try connecting your monitor and your PC with a new cable to see if this issue persists. If not, this issue is caused by your video cable.

If this issue remains, try connecting your monitor to another PC. If your monitor still shows the no signal message, it may suggest it is the monitor that causes this issue. In this case, you should contact the manufacturer of your monitor for further assistance.

5: Update your graphics driver

Sometimes the monitor no signal issue may also result from faulty and incompatible graphics driver. Try updating your graphics driver to see if you can resolve this issue.

Please let me know if these steps will help you resolve your issue.

Thanks and regards,
