We bought this cable to replace one that had begun allowing noise into the VGA signal. Once we switched over to this cable, the projector signal cleared right up. Two things I like about this cable: it's a bit longer than the one it replaced, so we have some play to avoid noisy items in the attic; and, it's a thicker cable than the one it replaced and I'm hoping that will make it last longer as well as being more resistant to EM noise.
I bought this to run up the wall, across the ceiling rafters to hook a laptop to a projector. I needed 50' length to do that. I had previously used a 10 cord and was a little concerned if there would be any difference in quality of the picture with the longer cord. No difference at all! I am very pleased.
