I have an old Compaq Armada laptop. The display is covered with white horizontal lines, and green red, and blu vertical lines. Kind of like a graph. Does anyone know how to clear this.

Does it run Windows? DOS? Does this hapen in both or only Windows or ...?

It's runnin NT 4.0. It stays on all the time. It is "On top" of the display. I tooled around with the display setting but nothing seemed to work.

Refresh rate possibly?

I tried that but the only setting available is " hardware default" There is no way to change the refresh. I can change all the display properties but that.

you change the refresh rate from inside windows? display properties and then to advanced?? then to monitor settings?

you don't have that?

Yeah I know that. There is a pull down bow that has all the possible display setting in them. When you pull it down it'll say 800x600 256 colors (hardware default refresh)
That is one example but all the choices have the hardware default as possible refresh,no other refresh rate listed.

The thing looks like a big grid placed on the screen. I've thought of the basic stuff like refresh rate, .....................display settings.

It is a Compaq Laptop I'm working on.
