How come my projector image wiggles every 5 seconds or so?

by on September 12, 2010

Q: I have two separate laptops connected to a projection screen via vga and a manual vga data switch to select “A” laptop or “B” laptop.

The “A” laptop works fine but the “B” display on the projection causes the screen to wiggle about every 5 seconds. I added up the length of the cables to 153′ and thought I might need to add a signal amplifier.

Many reviews state most applications don’t have a problem with 100+ feet of vga cable. I don’t know about 153′ though. Anyone have thoughts on this?

    The length could be a problem. I’d suggest you experiment with dropping the length down to see if that makes a difference. If it does, and you still need that kind of length, then consider a signal amp.
