Windows 10: primary monitor stopped working after Windows update. All the fixes rely on the primary...

I update Windows 10. My primary monitor stopped working. I look for solutions, and they all assume that the primary monitor works. E.g. opening Device Manager - well it opens on my primary monitor and I can't see it.

Primary Monitor Stopped Working

I have a Sony Vaio VGC-JS290J All in One Desktop configured to drive a second monitor via a DisplayLink USB Display Adapter.

Everything was working fine for a long time and then I advertantly pulled the adapter from the PC. Once everything was back running the main display monetarily flashes a display during a boot cycle or shutdown and then the primary display goes dark and only
the second display works, I have tried various configurations, reverting to only the primary display, coming in over a remote PC. reloading drivers, disabling displays, etc.

Bottom line - Windows thinks the primary display is working fine and I can figure it as the primary or second monitor, I can configure it as a duplicate or do it as extension. The display configuration thinks it is working but other for a brief second when
booting or shutting down the computer, the main display stays black. I know the monitor is working because it does momentarily display. I tried upgrading from Window 7 to Windows 10 hoping it would fix it but no cigar. Is there a registry entry that could
fix this problem? How do I do it?

 

The taskbar locked to bottom of secondary monitor moves to the primary monitor whenever primary monitor is switched on.

See the title.

I have the taskbar locked at the bottom of the secondary monitor so the primary monitor is completely empty for watching movies, games TV etc.

Whenever I turn the primary monitor on, the taskbar immediately jumps from the bottom of the seconday monitor over to the bottom of the primary monitor. I then need to untick the 'Locked' option on the taskbar, drag it back to the secondary and tick 'Locked'
again.

The taskbar disrupts desktop icons on the primary and any application running on the primary monitor at the time and quite frustrating.

Primary monitor is an Asus PB328, connected via Display Port to the PC.

Secondary monitor is a Samsung 24 connected via DVI to the PC.

I expect the taskbar to remain where I place it when locked, regardless of monitors been switched on or off.

The sequence of turning on the primary and secondary monitors has no impact. As soon as the primary monitor (Asus on DP) is turned on, the locked taskbar moves to the primary display, regardless of whether the Samsung is on or not.

 

I want to move spell checker window to a non primary monitor

I use my Internet Explorer on my secondary window. I have a misspelled word, I right click, the window with suggestions add to dictionary, is on the primary window. I don't want that. If I change primary and secondary windows, I can't move my mouse left
to right, its stops at the new secondary window.

I want to move the suggested spelling window to the secondary monitor.
