Last night my secondary 19" display started going black.
If I switched it off and then on, it would display the signal, then go black again after a while. This time period got shorter and shorter.. and now it just displays the signal for a fraction of a second.

The display also emits a kind of electrical buzzing sound before going black.


1. Any ideas what might be causing this? Can I fix it, or should I just start looking for a replacement? The display is quite old so I don't think there's any warranties left.
2. If it can't be fixed, what kind of display setup do you recommend? I have been running a 1680x1050 along with a 1280x1024, been working fine, but last night I started 5-boxing on the single 1680x1050, and it was really nice to have all the views so close together. I'm thinking it might be worth getting one really high resolution display instead of several displays.

What do you think?
