So Catherine was telling me how an FPGA with an HDMI port can emit high definition video by rapidly emitting pixels at the TV's scan rate.

But what I learned talking to the Analogue Pocket community is the Pocket has a maximum resolution (cannot exceed in either direction, not even on hdmi) of 800x720. And that appears to be partially due to the "two layer" FPGA (one FPGA is running "the software", the other FPGA is doing moment-to-moment gruntwork like servicing the USB port). But when I asked, the said 800x720 means sending color data at a *very high* clockrate and probably your FPGA code would struggle to meet 800x720 deadlines anyway.

Is this surprising to you?

Do you think a Cyclone V comparable FPGA (for example, the colorlight i5 or i9, which I've been trying to order, and the board I'm ordering has an HDMI connector) in principle can transmit 1080p or 4k video?
