FACE IT STRAIGHT. GO FOR BROKE.

This is occurring for me for my ASUS ROG PG279Q using this HDMI Cable

Cold boot did not work initially, however after plugging and unplugging the dock connector back into the Deck, I finally was able to get it to display.

Same thing with sleep/wake; Connected and displayed after taking the previous steps mentioned, enter sleep mode, wake the device, no display. Disconnect and reconnect the dock connector, correctly displaying.

Thank you for looking into this.

Safari seems snappier
