Description Support Documentation   The cable test and repeater test can be used when the source and sink ends are collocated, in other words can be connected to the 780/780A Tx and Rx ports. For a cable or distribution system that is installed and where the source and sink ends cannot be connected to the 780/780A, you can use the Frame Compare feature. The Frame Compare feature captures a reference frame and then compares a series of captured frames pixel by pixel to the reference frame. The HDMI/DVI Cable Test runs a test on all the leads in the HDMI cable and HDMI links (when extenders, splitters, switchers and repeaters are used) except the power bus as follows: - Pixel error test using a pseudo-noise pattern on the TMDS lines using three separate timings: 480p60 using 8 bit/component color 720p60 using 8 bit/component color 1080p60 using 8 bit/component color 1080p60 using 12 bit/component (deep color) - Read/write test on the DDC leads and the CEC bus. It reads an EDID at the output from the input. - Continuity test on the 5V/Hot plug leads. -Hot plug delay and hot plug pulse width. The hot plug delay is the time that elapses between the falling edge of the hot plug line on the on the sink side of a repeater and the falling edge of the hot plug line on the source side. The hot plug pulse width is the time that the hot plug pulse goes low as detected on the HDMI Tx side. What you can do: Verify HDMI cables. Run tests on HDMI cables. Test for pixel errors on multiple formats (resolutions) on the TMDS video and check continuity on the 5 volt, hot plug and DDC lines. Prequalify HDMI networks (prior to installation) with Repeater Test. Verify HDMI networks comprised of cables, audio/video processors, extenders, switches, repeaters, etc. prior to installation. Test for pixel errors on multiple formats (resolutions) on the TMDS video and check continuity on the 5 volt, hot plug and DDC lines. Test HDMI networks (once installed) with Frame Compare test. Verify HDMI networks comprised of cables, audio/video processors, extenders, switches, repeaters, etc. once installed. Test for pixel errors on the TMDS video.
