Thanks Andrew! I played around a little bit with the refresh rates. Between
40-60Hz there is no difference in idle power consumption. The mem clock stays
at 875Mhz and can't be changed.
The best refresh rate

--- Comment #16 from Andrew Sheldon ---
One possibility could be to create a custom modeline, perhaps trying refresh
rates between 30-60hz (starting with 45hz), so you can find a point where the
high idle power usage kicks in. Reduced blanking

Thanks Andrew for you comment! Sadly that doesn't apply to me. My 49WL95C-W is

higher then 60 Hz. The display can't have a bigger refresh

Okay, so in my case, it turned out to be a problem with >60hz refresh rates. If
I set to 60hz, the problem goes away.
