When I connect an external display while the Surface is already turned on, the external display is flickering. When I restart the Surface with the external monitor already attached everything works fine. Disconnecting the Surface then and reconnecting
- same problem. The flickering appears with different monitors, different cables and with different connectors (Surface Dock or USB-C). I have the 16 GB, i7 Version of the Surface 7 with an up to date OS.
Update to Windows Build 2004 and Firmwares 13.0.1319.2 and 8.123.140.0 through Insiders Update looks promising.
It took over 2 hours to install on my SP7 but finally graphics appear stable.
The Intel driver hasn't changed, but I haven't seen a single event log entry like previously including when coming out of sleep mode.
Am going to go to sleep myself now... see how it runs tomorrow.
