VGA over CAT5e

BigAl.NZ · 2008-10-06T04:05:00+00:00

Hi Guys,I need to get a VGA signal from the Nav Station in my boat to themonitor in the bridge. I could just run a VGA cable (about 4m worth)but I need to pass the cable through some small holes for the looming(sp?) and the DB15 connectors wont fit unless I make the hole bigger.I am thinking about running the VGA singal over CAT5e, which a Googlesearch seems to suggest is possible. I was wondering if anyone had anybetter ideas, keeping costs fairly low.Has anyone here had any success cutting the end off a VGA cable andwiring on a new DB15 for example?Thanks in advance,-Al

mmm wouldn't surprise me. I've seen VGA extension cables as short as 2M exhibit ghosting.

There are well built VGA extension cables (use 75 ohm mini coax cables at least for RGB signals). Those work generally well. Also there are those crappy cables built just from general purpose computer cable with lots of wires inside one outer shield. Those cheap cables have typically wrong impedance and considerable crosstalk between signals -> ghosting problems

Then the used resolution + refresh combination has effect. Almost any crapphy cable works for 640x480 60 Hz resolution but for 1280x12o4 and higher resolutions the quality of the cable starts really slow up.
