hi there, i have a problem setting up my sony vaio laptop with my panasonic plasma. i recently brought a new lindy svga cable to go from the monitor port on the laptpop to my plasma, the problem is that the picture seems to jump slightly every few seconds? i dont know if i have to change any settings on my laptop or there maybe a fault with the cable or tv? the max resolution of the laptop is 1600x1200, do i need to change this? please help!
