So we have just recently had a problem with the video card on our WSI Alert computer. Called WSI and got it replaced. We have a DVI splitter cable to allow the local monitor to see the computer and a Gefen Cat5 9500HD extender to show the monitor to weather. The video was not passing through the splitter after we replaced the video card. So I looked at getting a Kamer VM-2HDCP. The first 2 did not work and the 3rd would not work with our HP monitor in the weather center. So we returned it and got another Tripp Lite splitter. Also the Gefen was not passing video either so we had to replace that too.
Moral of the story... avoid Kramer. Their stuff has failed to work at every chance we have given it. We have tried them on other occasions and it has never worked out for us.
