Visible flyback lines on vorlon's Sun GDM5410 monitor today. This is not a good sign. Both of my monitors, it seems, are on their last legs, and there isn't really spare cash in the budget right now to replace them. (Technically, there's cash in the bank, but I don't want to cut into it until we have to.)
We have one spare GDM5410 upstairs in storage, but I'm not convinced it's in much better shape than this one is. They both seem to have the same problem — severe loss of screen saturation, requiring turning contrast all the way up to get any kind of decent saturation at all, which then forces turning brightness all the way down to have the screen not be washed out. I suspect it's a design flaw on this monitor series, which is a terrible shame, because the completely flat (horizontally and vertically) CRT is the best I've ever used as far as image quality and lack of glare, and unlike an LCD, it continues to look good at resolutions which are not exact power-of-2 divisors of its native maximum resolution.
