Kramer TP-580 Reviews
Ease of ordering
On line system worked well
Did not work for my application
I purchased this product with a matching receiver to connect a laptop to a projector. I ran shielded cat 6 cable (150ft) from the laptop to the projector. When trying to connect the laptop, I could see the projector name in my options dropdown but when I selected the projector, nothing happened. I understand they are directional. HDMI OUT was going to the projector and HDMI IN was coming from my laptop. The projector could not find a signal. All lights on units indicated a connection. I tried powering things off and on and tried a bluray player thinking perhaps it was my laptop. The projector never detected a signal. I thought perhaps it was an issue with HDCP but the manual says these support HDCP. Maybe these don't work over Cat 6? In the end I tried a similar unit by a different manufacture (of lesser quality in my opinion). Same cabling, same laptop, same projector, and that unit did the trick. Before writing this review I tried the units one last time to be fair. I used a cat 5 cable about 20ft long and connected it to an HDTV. It appears they will work with this combination. So they get 2 stars instead of 1. This is my 4th time having to use HDMI over cat 5/6 cable. All applications have been with different manufacturers and all have developed issues. 3 previous will experience drop outs in signal, this unit didn't work for the application required.
