m15 R2, screen goes black randomly

Question

I've had my Alienware m15 R2 for about a year now (purchased new direct from Dell in March 2020, warranty is now expired).  I've had some issues with the screen for a while, primarily weird green patterns on the display when the computer boots, but those would disappear after the boot screen usually. On very rare occasions, I would experience the screen going black, but not enough to be too bothersome. However, a few months ago the screen began randomly going black every few minutes to every couple seconds and it is driving me nuts. It is now more common for it to happen at least once during a usage session than for it to not happen, and restarting the computer doesn't seem to effect it either way. I have noticed that this never happens when I am playing games or using any program that I know for sure is using the dedicated graphics card, it only seems to happen when I'm web browsing or using less graphically demanding programs (like Office) that should be using integrated graphics. And I can always get the screen back on by resetting Windows' connection with the display (Win+Ctrl+Shift+B). All of my drivers are up to date and the issue has persisted through multiple driver updates. Here are my relevant system specifications for reference: 4K OLED 60Hz Display Intel Core i7-9750H  Intel UHD Graphics 630 NVidia GeForce RTX 2070 MaxQ I'm hesitant to assume it is a problem with the physical cable connecting to the display or the display itself because the issue only seems to occur when using integrated graphics. But I cannot find anyone else having a similar issue with an m15 R2 on any forums either. Any help would be appreciated.

Same!

Given what you said, I thought it was b/c I disabled GPU acceleration under Graphics Settings* but that has no effect. Same for updating drivers, restarting, unplugging and plugging my external monitor back in (the laptop screen goes black regardless).

* Settings->System->Display->Graphics Settings under Multiple Displays->Hardware-accelerated GPU scheduling->On

Hi @duloc welcome to this free user to user Alienware laptop discussion forum. This is not Dell Support.

Please run the windows Reliability Monitor and wait for event timeline to be loaded. As screen now goes black during most sessions, this reoccurring event should be reported for most days. Open one of these reoccurring events and look for root cause. How to use Windows Reliability Monitor to identify software issues | Dell US
