T480 Monitor flickering in Visual Studio

2019-01-09, 19:23 PM

Hi,

my laptop monitor (not external monitor) starts flickering an a regular basis as soon as I start Visual Studio. Not always and not only with VS but very consistently.

 

I know that there were some unresolved flickering issues last year, so I wanted to check if there are any updates. This is a deal breaker for me.

 

It seems to related to the software (e.g. visual studio) and somehow to the scale setting of windows. With the recommended "200%" I get it very consistently in VS. With "175%" it seems to be better for now.

At two occasions my display flickered very heafily in VS and then shut down. Had to close and open lid to get it running again.

 

I have updated my BIOS to the newest version (BIOS Version/Date LENOVO N24ET44W (1.19 ), 07.11.2018)

Display drivers too. Intel: 24.20.100.6344, Nvidea: 24.21.13.9836

Resolution is 2560 x 1440 x 59 hertz with 200% scale. Both the "recommended" settings.

System Model 20L5000BGE

Try to disable Panel Self-Refresh in the Intel Graphics Control Panel. Make sure you do this for On Battery and also Plugged In. It's in the power options.. I had this issue with VS2017 and a few others apps on a t480s.

Seems to help for now. Will mark as answer if this works for a bit longer. You never know.

 

For everbody wondering where to find that: Desktop -> right Click -> Intel Graphics Settings -> Power -> Panel Self-Refresh: Disable

 

Any idea why Self-Refresh would cause a problem and if there is a fix on its way?

Depending on the panel in the machine, it changes the refresh rate from 60Hz to a variable rate to save battery, but not by much.. Some panels cannot support this change so it doesn't update properly and thats why the bottom half of the screen is affected the most. As for total blackout after a while, I'm not sure why it does that but it was a real pain at first when it did it.. It was random for me at times but it was worse in VS2017 (Even with Dark Mode as I prefer that option) or in Chrome.. This is just what I know from a little research as looking up "Panel Self Refresh" seems to refer more to mobile devices instead of the laptop panels.
