Windows 10: Grey Screen after switching to display port.

Hello there,

I recently switched from HDMI to DisplayPort as my monitor can handle 144hz, and just ran a test to see whether my HDMI cable still made the display look greyish and it doesn't have that much grey in it compared to the DisplayPort. The DisplayPort is more greyish and I only came to notice it when I switched the cables. What's happened here?

Dual monitors not set up correct

Hi Mike,

Thank you for bringing this to our attention. This might be due to incorrect settings. In Display settings, kindly check which monitor is selected as the main display, and press the
Windows key + P, and check how your displays are projected. (PC screen only, Duplicate, Extend, or Second screen only)

In most situations, when display 2 becomes display 1, it means that the ports are not connected to their proper ports. We suggest switching the ports, and check if it helps.

Your reply is most important for us to assist you accordingly.

 

Screen turns grey and switches off

When i start my laptop, after windows start up the screen turns grey and the laptop switches off in 1 minute.

 

Fixed this with a little search, seems that I had to go into the NVidia Control Panel and then "Change resolution". On that screen, I changed the "Output dynamic range" setting from 'Limited' to 'Full'.
