I am driving two Sanyo XT-21 projectors from a Dell laptop, via an RDL
1 X 2 VGA/XVGA distro. The desktop image on one projector will project, go dark, project, go dark, ect and this will alternate between projectors. what is happening, how can I correct this? | moderator Joined: Mar 28, 2005

There is no reason for that to happen. The RDL may be bad, or a cable is bad. If you don't have the issue with a direct connection to each projector with each cable, then it points to the RDL. Likewise, it could be a cheap VGA cable - to long, not large enough. I would pick up a high quality VGA cable and maybe a better D/A... http://cgi.ebay.com/New-Extron-P-2-DA2-Plus-VGA-Distribution-Amp_W0QQitemZ230368578272QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item35a3098ae0AV Integrated - Theater, whole house audio, and technology consultation during the build and installation process in the Washington, DC metropolitan area. | --- Advertisement ---

I used 3 runs of RG-6 at about 75' each to each projector, still flashes with the computer driving the cable directly. | moderator Joined: Mar 28, 2005

For whatever reason, it sounds like a cable issue then and you might have more luck if you pick up a couple of these... http://www.monoprice.com/products/product.asp?c_id=102&cp_id=10201&cs_id=1020101&p_id=3573&seq=1&format=2You really shouldn't be having issues with the cabling at 75', but you may want to try to double check by putting the laptop closer with a short VGA cable to ensure that the projector itself isn't having issues.
