Vga connection to monitor

[rbk44]

I have 22 inch lcd hdtv monitor and it came with (i'm assuming) a cheap vga to vga cable. I use this cable to connect my laptop to this monitor.
The problem I'm having is that the connection seems to be bad because the picture tends to shake and wavy lines go up the screen which is very annoying and makes me dizzy. Some days are worse than others but even on the best days you can still make out the fuzzyness and screen shaking. Does anyone know why this is happening? Is it because I'm using a cheap vga cable and if I buy another one, would it solve this? I'm not 100% sure if it's simply interference, although it may be the case. Any help would be appreciated

It may be the cable, but try using different refresh rates for this monitor. You should be using 60Hz.

Also, find out what the native resolution is for the display and use that setting.

There is no real difference in performance between VGA and DVI, so don't go there.

I am using the native resolution (1680x1050) and it has always been set to 60Hz so those are not the problem. The only explanation I can think of is the cheap vga cable but does anyone know if the stock cables that come with monitors are really that cheap and don't provide all the interference blocking? Or anyone have any other ideas?

More info - the wavy lines and shaking seems worse on sites that have a dark gray background (ex. espn.com where the sides are that dark color the screen seems the shake more) it's very strange...
