i'm having some problems with my new RX 480. I'm using al Dual Monitor-Setup with one BenQ RL2460HT (at HDMI-Port) and a BenQ RL2450HT (with Adapter at DisplayPort).
The RL2460HT has an HDMI output which I use as Input for a third Monitor. However as soon as I install the Radeon Software and driver the output of the third monitor turns pink. This happens only on Windows 10 Pro with Radeon Software 17.4.2 and 17.4.3 It doesn't happen when using Linux and with the standard Microsoft Graphics Driver.
I'm a little hacked of by this and thinking about returning the RX480 and getting a GTX 1060
When I restart my computer through Windows the driver seems to forget my settings for primary and secondary display etc. If I shut down the system and boot back up it's fine.
