How long to extend 15pin VGA cable

[LoverBoyJ]

I'm not sure if this was asked before, did search but none came out.

I need to extend the VGA cable due to my desk width and hieght. Whats the recommended max lenght of VGA cables and DVI cables? Will there be a huge signal degrade, and picture quality?

I'm using a 25' VGA cable for my HTPC with no loss of quality with a quality cable. I've seen high end 15 meter DVI cables for sale, but IIRC 7.5 meters the recommended maximum, but not sure.

Ok, Thanks,

I only need an additional 4' but all I can find at the stores are 6'.
