Hi Phillipp
My SL was attached to a 27" UHD Acer S277HK Monitor.
I can disable those for the next patch but I get the impression thats
not the only issue here as I've gone from being able to get a picture
(but not the right res) in 4.10 to not getting any HDMI signal at all
with this patch.
Those flip errors have to be another bad sign, right?
Thanks
