Windows 10: DisplayPort No Signal, Black Screens

I bought this PC April 2021 https://www.bestbuy.com/site/cyberpowerpc-gamer-supreme-gaming-desktop-amd-ryzen-7-3700x-16gb-memory-nvidia-geforce-rtx-3070-1tb-ssd-white/6434646.p?skuId=6434646While using the PC my screens will go black and say "DisplayPort no signal." From there I have to hard reset it. Once this happens and I try to turn the PC back on my screens do not light up. I've sent the PC to Cyberpower 2 times for service and they replaced the GPU each time, as well as the RAM once. They say they can not recreate the issue.There is no rhyme or reason as to why or when this happens. What

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.

Fix for black screen/no signal

Easy Fix for Black Screen/No Signal after Dedicated GPU Driver Install, OS Windows 10

The problem (at least in my case) was the Windows 10 default settings for my monitor/TV were way too high; above 3000 X 3000 and a scaling setting of 300% this
did work with the Basic Driver

Step 1: You need to reboot into your on board GPU or into safe mode

Step 2: Go to the search panel and type in Display Settings (Bottom left of screen) you will be given a list click on the top item which is Display Setting and it will take you where you can alter the setting

Step 3: Change to what better suits your monitor e.g. 1862 X 1048 or may be even lower at 100% (HD TV) You may need to uninstall the Dedicated GPU driver and reinstall it.

Hope this is of help
