My Microsoft Surface Pro 4 screen keeps flickering. I provide the following details if anyone can assist.
Details of Surface Pro 4:
Processor Intel(R) Core(TM) i7-6650U CPU @ 2.20GHz 2.21 GHz
Installed RAM 16.0 GB
System type 64-bit operating system, x64-based processor
Pen and touch Pen and touch support with 10 touch points
Edition Windows 10 Pro
Version 20H2
Installed on ‎23-‎Oct-‎20
OS build 19042.746
Display adapter details:
Intel(R) Iris (R ) Graphics 540
Software Components:
Intel (R ) Graphics Command Centre
Intel(R ) Graphics Control Panel
Intel (R ) iCLS client
Solutions attempted:
1)"Visual Studio I" uninstalled.
2)Disabled Hyper-V by typing (using cmd command which was run with administrative privileges) the following dism.exe /Online /Disable-Feature:Microsoft-Hyper-V
3)Restricted the screen refresh rate to 60 Hetrz.
None of these solutions helped screen still flickers. Surface Pro 4 will only stop screen flickering if connected to an external monitor.
Would appreciate if you have any suggestions to stop screen flickering.
