Hello,

please take a look at this video:
. It shows the glitches I experience on my secondary monitor after I wake my computer from energy saving (starts after 30 minutes of doing nothing). My main HDMI screen is not affected by the glitches, however it seems to be dropping frames and is less responsive. I use the Nvidia Web Drivers and my secondary screen is connected via a DVI to VGA adapter. Maybe that has something to do with it, although it never occurred before on El Capitan.

Please help me if you can
 
Apple have not used VGA in their products for more than ten years and therefore there is no support for it in their operating systems.
Some hardware configurations do work but it is largely hit and miss.

but it worked just fine before :(

I guess it's time to replace my 10 year old screen now or is their any way I can fix this?
 
Make sure that X86PlatformPlugin & AppleLPC is loaded. Check if AppleIntelCPUPowermanagement isn't loaded if it's loaded then something is up with your setup. Haswel+ uses XCPM not AppleIntelCPUPowermanagement. Also check if SBUS is loaded. Sleep problems are caused by lack of Powermanagement & USB problems.
