One DM8168 can output only two independent channels display, Now I want to increase the decoding performance and ouput four independent channels display, so I cascade two DM8168 chips for four independent channels display.
There are some problems for me to do it:
1. Could DM8168 chips cascade output four independent channels display?
2. If the DM8168 chips cascade output four independent channels display, How could I connect the two DM8168 chips? Use PCI-E?
3. Does two DM8168 chips need their own independent systems, including the Linux Kernel, application and etc?
