This is a followup thread to :
Intel i7 PC
ATI R9-295x2 powering a 65" Panasonic Vierra 4k TV via DisplayPort 1.2 in 4096x2160
When switching over from PC (Displayport) to my other HDMI connection (going to a laptop) and back to displayport. There is no signal being sent to the monitor.
This problem did not happen with drivers 14.12 and started with 15.7 and now also 15.12
This is still a problem... can someone at AMD acknowledge that this?
