Bad combo = Win10 + DiaplayPort VGA adapter + L1940p wide Thinkvision

We recently discovered a weird combination of OS, displayport vga adapter and monitor. Once an end user upgrades to Windows 10 from Windows 7, their Thinkvision monitor attached with a displayport adapter will no longer be hot pluggable, or if they are already using a vga sourced monitor, the monitor using the adapter doesnt work. Does anyone have any ideas? This exact setup of hardware works just fine with Windows 7.

I have upgraded drivers, swapped cables, updated the BIOS, and have tried different model computers. Nothing I tried has made this combination work. I am thinking that the monitor L1940p wide thinkvision is too old. If we attach a newer hp monitor to the displayport vga adapter, it works fine.Normal VGA connections work just fine as well. Also a displayport dvi adapter works with the thinkvision monitor.

I am beginning to think that there is some form of acknowledgement that is not happening when using the old thinkvision monitor, which in turn never tells the OS to send power to the displayport adapter.

If anyone has some ideas or thoughts I would greatly appreciate feedback.

Thanks!

Smells like Windows 10 driver issues yeah, I looked it up, that monitor, it is from 2008, get a new one, a 19"? WHOA!

11 year old monitor..... 4 year old OS, yeah driver problems likely!

I do wonder if Display Fusion would help, it's reasonably priced multiple monitor utility with a ridiculous # of options, been using 4 years or so.

Seems like it may be old monitors just not working. I tried other monitors, some being the same model and it was hit or miss if they worked or not... Thanks for your replies
