When I cold boot, a black twister or corkscrew appears down the middle of the monitor. It remains there when in dos but when windows desktop appears it goes and leaves only a slight black line down the right hand side of screen, after a few minutes it disappears. I am running win98se and the monitor is a 21inch ViewSonic. I have tried to look at on screen menu to check settings when in boot mode but it comes up as bands of colour across the screen. When in windows it comes up as normal and changes of settings do not affect the problem. I am hoping that some one can recognise the symtems I describe above and tell me that it will not be expensive. Regards G.
No chance off magnetic interference as only 2 shielded speakers that I removed with no change. I run 2 computers through the monitor using a changeover switch box, same on both. Also have a 17inch spare monitor and OK on that. I need the 21 inch moitor as it is better for working with photos at high mag. Thanks for your response. Regards G.
Yes it started a few weeks ago, I will try direct hookup, bypass switch. Hi Djohn, you mention same thing. I will try that, its a horrendous mess of wiring due to the way I have linked various hardware and the two boxes plus the sound linked the same way. Will inform Sunday evening of results as I am up to my neck in other things right now. Thanks for your input, Regards G.
