Common problems and solutions

Monitor problems

My monitor is blank (or it has shades or spots of gray and
white).
Make sure that Matrox 4Sight and your monitor are turned
on.
Check that your monitor cable is properly connected.
Make sure the brightness and contrast controls of your
monitor are set correctly.
Set your monitor's input impedance switches (if any) to
75 ohms for the red, green, and blue inputs. Set the
synchronization switches to high impedance and external
sync mode. If there is a Digital/Analog switch on your
monitor, set it to Analog.
When I run an application, there is no picture on my video
display. The monitor is blank.
The application you are running might be attempting to use a
resolution that is not supported by your monitor. Check your
monitor's manual for supported resolutions.
