2nd Monitor

Hi

Thank you for helping me. When it is on duplicated both monitors have same resolution, however, the 2nd monitor the text is unreadable and screen blurred. If on extended my default monitor is fine but the 2nd monitor goes off and my laptop screen comes on.
I wish to have both default and second monitor displaying at the same time. As it is the 2nd monitor drop down resolution is showing 800x600 and is faded out and unable to change it.

 

Color Display on 2nd monitor

I am using Windows 10 on a Dell laptop with a 2nd monitor which has been working fine. For some unknown reason I have suddenly lost the full color range on the 2nd monitor. I don't know if I have changed some setting by accident or what. I have tried
resetting the defaults but that didn't change anything on the 2nd monitor. The primary screen on the laptop continues to work fine. Any suggestions what needs to be done to restore the full color range on monitor #2?

 

When I use an app in the 2nd monitor the resolution is fine. Just the desktop and the task bar resolution is too big on 2nd monitor.
