Graphics are weird after wake from sleep.

When i wake my pc from sleep the graphics are very blurry if you look close you can see bars going up and down the screen. To fix i have to go to a lower res to a higher res. and it happens again after every sleep.

Thanks

 

Waking PC up from sleep mode causes a reboot

Problem:





I have a small group of Dell Latitude E7470 (Bios Version 1.11.3) laptops that have and sleep mode issue.





When a user closes the top cover of the laptop and puts the machine to sleep all appears normal and the power light begins to pulse. Then, when the user opens the top cover to begin using the laptop
once again the laptop fails to wake up from sleep mode and restarts causing the user to log into the laptop each time. The laptop behaves this way regardless of the way it entered sleep mode, e.g. via the power button or from the start menu.

• The laptop power settings are defined by group policy.
  
• All of the affected laptops are running Windows 10 1809 Enterprise.
  
• The issue does not appear to be a user problem as the issue occurs whether or not a user signs into the laptop.
  
• The bios was updated prior to imaging the laptop in the spring of 2017. v1.11.3
  

Troubleshooting:





The following steps have had limited success.

• Bluetooth on/off. Sometimes if we leave the Bluetooth off the issue goes away, but not always.
  
• Changing what closing top cover does, e.g. change the setting of the top cover to do nothing when closed and then return the setting back to sleep when the top cover closes.
  
• Swapping SSD from one computer to another identical make/model computer and then back. In this step, we move the affected SSD to another laptop and boot the computer. then log in and test sleep mode.
  at this point, the issue is not present. Then, we place the SSD back into it's the original laptop, so far, this has been successful, however, we are still not confident this is a long term fix and we would like to understand why this step would have the
  effect that it does.
  

 

computer wake-up after sleep

Did all the steps exactly as shown above and "Allow this device to wake the computer" was already selected.

I think you might have miss-understood the problem. It appears that the computer is waking up, but it doesn't re-connect to my display. I have to turn off the display and turn it back on to get my display to to re-connect. This was not a problem prior to
the last Win 10 upgrade.
