You should try better power conditioning, in that case. I find monitor
failures to be very rare and still have several 10+ year old monitors that
I use for service, with pictures almost as good as when they were knew.

One of our three Sony GDM17SE1 monitors finally failed, but I used
some of the parts to convert a Silicon Graphics monitor of the same
basic chassis and vintage to separate-sync a few months ago.

I use a Square D whole-house power line filter/surge protector, and APC
SmartUPS's on most equipment.

We buy Sony, NEC, and the occasional ViewSonic. They all have excellent
longevity. The Mags we bought a few years ago are pretty much all ready for
the trash just because the image was never very good, even when new.

Three years is about all I expect from a monitor. By that time they all
seem to fail. Note, however, that I live in an area where severe
thunderstorms are an almost daily experience for several months of the year.
