Until a few weeks ago my monitor was fine but then one day...
to cut a long story short, My monitor doesn't display red anymore.. it shows it as black... green is more yellow then normal but most other colours are fine.. do i need a new monitor or can this be fixed with a software filter of some kind? It is a acerview 34t... Just incase its common with these monitors...

Before you race out and buy a new monitor, check to make sure that one of the pins on the cable is not bent or some such. I have had this happen to me at odd times over the years, and in a few cases found that a bent pin was not contacting the VGA socket on the PC properly and one of the colors washed out.

Of course, your red circuitry on the monitor may be NFG...

Always worth trying is monitor swap with another PC to confirm the trouble is actually the monitor.

Best of luck.

Hi if the above does not cure this then try to flex the signal cable where it enters the monitor to see if this alters the red, if that does not help try tapping the case of the monitor to see if the red returns, it is quite common for monitors to loose a colour, if you are able with this monitor turn up the brightness to max & the contrast to min and see if the background colour is grey if so the CRT is OK and it may be dry joints or failed video o/p device or pre-amplifier.

Hope this helps

Rich
