Thanks for the response ESP_Sprite. I knew that the 3 lanes needed to be encoded in the 10 bits but for some reason was thinking that would only be an issue of eating up clock cycles. Somehow it hadn't occurred to me that the transmission of that data would be the real bottleneck. Doh! Would a RGB->...

The short of it: Is the ESP32 powerful enough to generate a single color HDMI signal at 1080p and 4k? The long of it: I'm looking to generate a single color HDMI signal when a input button is pressed with sub millisecond latency. I know an FPGA can do this but I'm wondering if the ESP32 is capable. ...
