possibly, a higher refresh than it's rated for might cause more heat, but i wouldn't expect the damage to show up as a color problem, i'd expect a deflection problem since that's the part you are straining (i.e. the electronics that move the beam across the monitor face). most likely the kds monitors are just junk.
the part of the electronics that drives the color information to the picture tube also generates considerable heat and they likely the manufacturer didn't provide enough heatsinking for it, it's not an unusual problem. how did the other monitors die? you may have driven color data too fast to the crt and helped speed the death of the cathode drivers (the part that drives the color guns in the picture tube) but i doubt it, you are actually driving color information at a lower speed than you would be at the higher resolution and slower refresh that kds recommends. you may be putting a greater strain on the vertical deflection, which would in turn put a heavier load on the power supply, which might explain the color problems. i doubt the high refresh is causing the problem, but it just might. you should be able to run at a lower resolution and lower refresh rate, you may have to select "all" in the monitors control panel for resolutions. is the monitor in a hot environment? have you accidentally impaired heat flow out of the monitor by placing things on top of it or under cooling vents on the bottom or sides? is it in a dusty environment (dust aggravates heat problems)?
