I use Win95. I have a monitor with "Teco" on it but other than that i don't know much about it. It doesn't even have brand names or anything on the users manual that came with it - only "high resolution microprocessor-based color display monitor" - that's all the info they give. (not even a phone number). The problem is i prefer it at 800x600 setting but when i change it to that - it works fine and looks fine - but i can hear a continous high pitched (not very loud) squeeling noise. The noise disappears when reset to 640x480. (where everything is so big you have to continually scroll...)
Also, if set to 800x600, the noise does not start till after POST has finished adn the Windows intro screen comes up. That's when it starts.
I realise with not much knowlege of monitors i prob won't be able to fix it myself but curiosity is killing me anyway. What is happening that makes this noise at a diff resolution?
