I am having problems with the colour on my monitor. Initially the problem was a “flickering” on the monitor causing the contrast to change from normal colour resolution to a “hazy” shade of green. The cable and connection appears to be OK. I have tested the monitor by connecting it to two other computers. The same effect occurred when connected to my laptop, but not on the computer at a computer shop I took the monitor to. I have successfully taken care of the “flickering” by turning off the hardware acceleration facility from Control Panel - Display. However, my monitor still displays a hazy green colour with all colours not being properly represented. There are no other problems with the monitor. Could there be a problem with the video card? What other action could I take?

It is unlikely to be a problem with the video card because if you have connected it to your laptop as well (and it creates the same effect) then it is very unlikely that both of your video cards have problems. The problem may be caused by the colour management option in the control panel. Go to ‘Start menu’ > ‘Display’ > Click the ‘Settings’ tab > Click the ‘Advanced’ button > Click the ‘Color Management’ tab. From here consult your computers/monitors manual to check if color profiles are needed or not and also double check that you have got the correct color profiles installed.
