I have a LED monitor (I think that's what it's called- it's a flat screen)- less than 1 year old. The mouse is a simple laser type. Today a problem started that I will try to explain clearly. When I'm scrolling on a page sometimes, it looks like the monitor might be starting to go out because it looks like old tv's used to look when the "horizontal hold" got messed up. It only happens on certain web pages- a couple on this board so I know it's not the website, plus it doesn't happen on every forum on this board. Once I quit scrolling the view is normal. I've had several web pages open on other tabs and it has happened on a few, but not all. Is this a mouse problem or a monitor problem?
