Hi there;
If I'm not misinterpreting the datasheet; It is emphasized that only one channel can be selected. We need two active outputs that can output simultaneously.
For example, the circuit whose picture I have attached/shared below provides output to both a 4K HDMI 2.0 (with HDCP) monitor and a VGA monitor at the same time.
We are designing a similar device. Both monitors must be turned on.
We are looking for an IC that can send images to both devices.
