Bit of an edge case here, so not sure how many are effected, might link this thread in my sig for visibility.
For those who are unaware, the LG 5K Displays have a habit of flickering from picture to black screen in W10. For me it only happens on Desktop, so not while in game, so was only a minor annoyance, however I accidentally found the fix...
Switch to best performance as per these instructions...
"Adjust your visual effects settings under Start > type performance > Adjust the appearance and performance of Windows > Adjust for best performance > Apply > OK. Head to the Advanced tab of the same window and ensure that Adjust the best performance of: is set to Programs as well."
edit: spoke too soon, appears to still have issues when playing youtube videos.
edit 2: I’ve done some more poking about and i may have found a proper fix - by setting Nvidia 3D settings to always prefer the 1070 - as suspected it was the intel igpu that was causing the issue as it was driving the external screen and the 1070 only kicked in when gaming.

@eightarmedpet Have you installed the latest Intel graphics drivers manually? There are more Energy settings which allows further tuning of the iGPU power consumption. On the 15" MBP, I need to disable the dGPU and attach the Intel iGPU to the internal display. When not connected to a power source, I would experience flickering. This was resolved when I turned off some power saving settings using Intel Graphics Control Panel.

I haven't but I will look into it! Are there any concerns around rendering my screen useless (black) if I uninstall all drivers? Apologies if thats a daft question, you know I'm not the most tech of people on here... ;-D

maybe this is the panel self refresh power saving feature you are experiencing? I noticed this on my HP and it caused my to think my trackpad was lagging when in fact it was the display slowing down the refresh rate and causing this slight flickering
Post updated, it was an issue with the intel drivers so I am now bypassing them.
Only issue sue I have now is getting constant 400 errors on this forum? Can’t be a shadow ban surely?

@eightarmedpet Regarding the 400 errors, I've experienced this issue too. It's likely a bug following the forum software update on Friday. We're contacting the developer to remedy this bug.

I had the problem with 400 errors. Deleting cookies for the egpu website in Safari worked for me.

@eightarmedpet, "Your post is really interesting, what did you mean by "....it was an issue with the intel drivers so I am now bypassing them....
thanks in advance
