my only concern is that switching between multi-display modes locks the memclock to 150 MHz, which in some cases can only be restored by rebooting in single display mode.
my 100% replication scenario is:
- set your computer to extended display mode
- turn off computer and second monitor
- turn on computer without turning on the second monitor
- you now get a wonderfull horizontal tearing/flickering because of the 150 MHz memclock
in some cases this can be alleviated by launching a youtube video in chrome (haven't tried other browsers). then the clock goes up to the regular 1500 MHz.
this scenario is so vast to me, because my second monitor is a tv which i'm not usually using as a second monitor and don't change the display mode before shutting down.
not even starting with voltage control via wattman...
