You look to have a dreadfully massive cataract that has formed and the decaying pva glue is clouding the screen. It is fixable but you need to remove the crt to clean it up.
Thus I don't think this is relevant to any computer monitors.
If you have a heat gun or hair dryer that can be set fairly low, you might try using it on a small section to see if the PVA will reflow. Note: you shouldn't have the heat set hot enough to melt the plastic faceplate.
