Windows 10: My Monitor keeps causing windows to lose display

I had a monitor that used a HDMI to VGA adaptor and when the Laptop was unlocked, I kept the windows open on the second screen. But The old monitor died, now the new monitor has a direct HDMI connection, but when I lock the PC, The display goes to standby. When the PC is unlocked, it appears windows has lost the connection to the HDMI monitor and all windows opened on the second monitor now appear on the Main display 1 instead. As I do a lot of CAD work and need multiple screens active. How do I keep windows recognising the second monitor even if it is on standby?The screen going to standby is

My Monitor keeps causing windows to lose display

I had a monitor that used a HDMI to VGA adaptor and when the Laptop was unlocked, I kept the windows open on the second screen.

The screen going to standby is acceptable, but Windows needs to stop dropping the monitor and moving all windows to the primary screen.

 

Dual monitor setup, Monitor #2 keeps losing color calibration.

Running dual monitors in Win 10 and when going through the Color calibration steps on monitor #2 (Control panel / Display / Calibrate color) the settings stick as long as the 2nd monitor is active.

If I switch to single display (Windows Key + P / PC Screen only) then the 2nd monitor loses its color calibration. Also anytime I reboot my PC (Even if I have both monitors active) the 2nd monitor loses my calibration.

The 2nd monitor has a fairly strong bias for the color Green so I can always tell right away.

I'm probably overlooking something and was hoping someone might of dealt with this before
