Windows 10: Suddenly when 2nd monitor is connected 1st monitor freezes

I have, for quite some time, been using two monitors. The primary one being a 32in TV and the second one being a 24in monitor. The primary one is connected to my pc by DP to HDMI; the secondary is connected by VGA. Recently, when I booted everything up in the morning the primary monitor would show no desktop&

2nd and 3rd monitors freezing

I'm on the latest Windows 10 version.

At random times (normally after leaving the computer in sleep mode) my 2nd and 3rd monitors freeze up, resulting in static images of what's there. I can still (somewhat) do things on them, but they mostly remain frozen. For example, I can make a fullscreen
application windowed (ctrl+shift+f) and vise versa. I can also move things from either one of the monitors to the 1st monitor, but I can't do this the other way around. When I move them, they still appear frozen on the 2nd or 3rd monitor whilst being dragged
to the 1st, and they stay there when being dragged from the 1st.

Turning off the 1st monitor (pretty much unplugging it due to the monitor) allows the others to function freely, but when I turn it back on, the problem restarts. This happens when unplugging the monitors as well.

 

2nd and 3rd monitors freezing

Hi,



Thank you for writing to Microsoft Community Forums.



I understand how annoying it can be when the monitors freezes at the middle of some work. Thanks for the information provided by you on the post.
To understand the issue better, we need some information.

• Did you observe any changes to the system recently, such as Updates to driver or Windows?
  
• What is the make and model of the PC?
  
• What is the make and model of the all the three monitors?
  
• How the other 2 monitors connected to the PC?
  

However, you can try the steps below and check if it works for you.

Device Drivers settings.

1. Press Windows + X key from the keyboard and select
   Device Manager.
   
2. Expand Display device. Right click on the device listed and select
   Update drivers
   
3. You will receive a prompt
   Search automatically for Updated driver.
   
4. Restart the PC and then check if the Monitor 2 & 3 freezes after sleep.
   

We await your response.

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?
