A quick tip:
Remember that it's very easy to adjust the vertical picture size of CRT monitors. Most have a dedicated v-size pot. inside, that you need to turn with a screwdriver.
You just need to open it up find the pot and beware of the deadly high voltage parts!
Works great, but a bit cumbersome if you want to switch back and forth....
A local techshop can mount in a switch. Costs a bit, but well worth the money and cheaper then a new monitor...
But if you just need an excuse to go for a nice new LCD-panel I never said a thing offcourse.
