My screen loses its color, the red disappears intermittent. I want to check if the graphics card or screen is missing. To do this, I have another screen available.
The computer has a graphics card ATI Radeon XPRESS 200 series. The current screen is a ViewSonic and I want to connect is a Samsung Syncmaster 750S.
I close the computer, I change my screen and I restart. There is current on the screen Syncmaster but no picture.
What am I doing wrong not to have a picture?
