Product Details

HDMI Cable Signal Tester

Testing an HDMI installation for proper signal transmission can now be accomplished easily and without guesswork. This HDMI signal tester connects between the source and display to verify that all components of the digital signal are being transmitted properly, thereby ensuring the best HD performance is achieved. The HDMI signal tester is designed to be connected inline with the video signal path, and can be located at either the source or display end of the system.

The HDMI format provides a convenient method of transmitting high definition audio/video information through a single digital cable. When the cable and connectors' integrity are good, system performance is excellent. If the data is disrupted by weak or incomplete transfer, the HD experience suffers. More than just a simple cable checker, this signal tester identifies HDMI interconnection problems and helps correct them!  Dimensions: 1-7/8" L x 1-5/8" W x 1" H.

HDMI Cable Signal Tester

Does this device work well with cable extenders such as HDMI over Cat5

IF there is a problem when using the Cat 5/6 extender, will the device when used at either end (source/destination) show the possible or probable cause of a defect?
Asked by: yrbndr
I use this product to help test and identify basic signal issues, including the use of Extenders. Typically if the extender is missing a pair or lack of power, this will show up on the led's of the device. For the price, it is very helpful in basic testing.

What does CK, DA, and HPD stand for?

I don't see what the LED's actually stand for. I have the unit plugged into the back of a blu ray player and the HPD does not light up.
Asked by: sully1967
CK stands for DDC Channel Serial Clock, DA stands for DDC Channel Data Line. The DDC channel allows the source device to read the data from the display to learn what formats the display supports. Most HDMI problems are a result of DDC errors.HPD stands for Hot Plug Detect, the display signals the source that it is connected and powered on.Keep in mind that this tester must be connected between a source and display.
