Oct 4, 2016 9:08 AM in response to asoderby dualhead,Similar problem here. DELL U2713H connected thru Belkin thunderbolt dock, and it gets no signal after sleep. The only way to get it working is reboot. Problem appeared after upgrading to Sierra.

Oct 8, 2016 12:06 PM in response to asoderby macNewbie_beGentle,I have this problem too though I can awake the display without a reboot just by by unplugging from the thunderbolt port and replugging. My macbook air is connected to two LG flatron w2343t monitors, one via the thunderbolt 2 port with an Apple Displayport to DVI Adapter and the other monitor though a DisplayLink Cable Matters Superspeed USB 3.0 to HDMI/DVI adapter. the problem only occurs for the thunderbolt adapter and only since upgrading to sierra.
