CPHD-1 HDMI Pattern Generator is a handy tool for evaluation and testing of displays/panels.
With the combination of its various timings, patterns and color spaces, CPHD-1 can provide up to 4095 types of video testing signals.
Besides video patterns, the generator also supports 3 types of audio testing signal, one built-in shine wave, one external analog audio, and one external digital audio input through S/PDIF.
The control over CPHD-1 is simple yet comprehensive, as you can use the on-panel buttons or remote controller to select from the timings, patterns, color spaces, DVI/HDMI output, and audio signal type, while you can also choose to use the bundled Windows software application to perform advanced control, such like timing/pattern programming, EDID reading and writing.
