Problem Description
I bought a monitor and wanted to use it as a split screen for my Mac. But after connecting it, I found that the entire screen seemed to be covered with a purple mask.
As shown below:
solve
Just change the monitor color space to RGB color space.
Open the monitor menu, find the color space option, and change the color space to RGB.
Of course, if you originally used an HDMI cable, you can modify it by using a DP cable. Because the lines are not connected, the transmission methods are also different. Maybe just change the line.
Here I still modify the color space.
as follows.
As you can see, there is no problem with the color display now.
