I already use several extenders in the auditorium I run.
(Extenders being a pair of devices, one that converts a standard signal to Cat5-6 networking cable to another device that converts it back to the original standard, for instance HDMI-Cat5e-HDMI, for extending the signal over a much longer length than is allowed by the original specification.)
I currently have a raceway with six 30m (100feet) UTP Cat6 cables from the BOH projection booth to the FOH lectern, and I have been running:
- HDMI extender (up from lectern)
- USB extender (down to FOH)
- 4x XLR extender (down to FOH)
- ethernet cable (down to an auditorium access point)
For the two remaining lines I want to have TWO VGA extenders (one low res (1024x768) to control the booth computer FOH, and the other (1920x1200) to feed the podium monitor with the projector signal).
The ones I have tried out have been poor and fiddly...you have to adjust the gain and peak on the receiver to compensate for the length of Cat cable...all the other extenders I've bought just work with no adjustment or issues. The issues I've been having with the VGA extender is poor picture, from softness to streaking to blotches (there would be NO WAY this would be good for projection for instance, and will be giving them 1-2 stars on my planned review on the reseller's site as well as returning them).
You may say it's because the VGA signal is analog and the rest are digital, except the XLR extender is analog and is in the same raceway and has just been plug and play.
So my question is, has anyone found a decent VGA extender, that doesn't cost a fortune, that actually works and gives a decent image?
