I have a Surface Pro 4 with the Surface Dock. I have its power settings all at default except that the When plugged in, PC goes to sleep after setting is set to Never. This means when I lock my PC or allow it to be unattended for too long, the monitors power down, but the Surface Pro 4 does not actually sleep.
I have three monitors:
- HP L2045w connected to the Surface Dock with a Cable Matters Active Mini DisplayPort to DVI adapter
- HP EliteDisplay E221 connected to the Surface Dock with a Cable Matters Active Mini DisplayPort to DVI adapter
- HP L2045w, in portrait mode, connected to the Surface Dock with a USB to HDMI adapter, then an HDMI to DVI adapter
I also have the Surface Pro's native screen active as a 4th monitor.
Here's how they normally show in Device Manager:
Monitor 3 always revives flawlessly. Monitors 1 and 2 usually come back up wrong. Either they never power on at all, or they come on at 640x480 resolution and are reported as a "Generic PnP Monitor".
The only ways I know to fix this, short of rebooting, are to unplug and replug them from the Surface Dock or to unplug and replug the Surface Pro 4 itself from the dock. Sometimes I have to get up and down a lot during a day, and it's a big annoyance to have to reshuffle my applications across my monitors.
Are there any fixes for this yet?
