Yeah, I think you're gonna need to tie into the ground on the module, which is probably the same ground on the computer chassis.

The issue you're having is the RFI/EMI from the LCD panel radiating back down the video line which itself is acting line an antenna. It'll get better if you shield the monitor, ground the antenna and/or wrap the video cable around a ferrite core. The latter two things will make more of a difference than shielding the monitor.
