Nice to see, that the HDMI-In gets attention. It’s one feature, that makes the M6 unique!
Tried the test via /opt/syna/bin/_ampclient_alpha 7… and have a question: How to get back to the linux terminal window? CTRL+C leaves me alone with a black screen, so I have to do a reset.
The “HMDI-In-Through” (via test 7) was without sound. It should be with, because it’s call AV-Test (A=Audio, V=Video).
BTW: Sound in complete system is still very choppy and disturbed in this version. Hope you correct that soon.
There are several models you can use for this in "models\image_processing\super_resolution\model" that will upscale to 4k. You can run these through the gstreamer plugin provided by Synaptics to capture the RX, run it through the model and output to screen (or save file)
