Normally my monitor continues to work fine - but from time to time (and it seems to be happening more and more often) without warning ths screen takes on a vivid pink hue. Everything's still on the screen, but tinged pink.
Whilst it makes a nice change to the "blue screen of death" I guess it's a foretaste of a more permanent failure in future.
Is it likely to be my monitor (a Mitsubishi Diamond Plus 92 - about 6 years old now) or something else (like the graphics card ?).
Sometimes it just corrects itself after a while - in fact has just done so as I type - sometimes not. Sometimes a restart fixes it - sometimes not.
