From: Yongqiang Sun <yongqiang....@amd.com> Issue: In case of two 4K@60 + one non-4k monitor, when unplug non-4k monitor, the remain two 4k monitor don't work properly. Reason: In that case, two 4k use two pipes and no split, when unplug happens, those two monitor will use 4 pipes and split, but on that time, frontend is not programed properly. Solution: After programed backend, front end should be programmed as per new pipe setting.
