Screen Problem - Tecra

A recently bought 500CDT Tecra is displaying win95 with a 1 inch border around it. The Display Settings from the Control panel are:display adapter: Chips Technologies 65545 PCI version 4
Monitor type: i have tried 800x600 ; 1024x768
When you bump up the desktop area above 640x480 and restart you get a black screen with colored blobs in a line horizontally across the middle of the screen

Can anyone help?

Either the frequency you are sending is too high, or the monitor cannot handle > 640x480  either by defect or design.

The screen is able to display 800x600. And can do so - but how do i do that?
As far as frequency goes, if that is the answer then how do i adjust that to get a good screen image through win95?

Frequency is adjusted through software (usually downloadable via internet) that lets you tailor your monitor. The idea is to get above 60hz. That is a harmonic of home and office lights, which can cause a minor (or not so minor) wave. I have mine set to 72hz (and no floursent lights around my monitor) The higher the freq., in theory the better the picture. I have found monitors have to be VERY well made to go above 75hz, without getting somewhat blured. You did say you have a c&t chip set, but not the maker of the card.
