Thanks for the info, and for staying with me. Either file type would be OK with a little massaging.

I've run CRU.exe and while I don't have the device yet, I do get the EDID info from my two attached monitors. If I want to get the 'auto hdtv' settings into a text or bin file suitable for the breakout board, what step are needed? It wasn't clear to me if I needed to have the board attached, or if I could just export the settings as a generic file, or if I needed to create settings based on one of my two monitors or...?

You can start with an existing monitor. You can delete all the resolutions and just add the ones you want. You can add detailed resolutions with Automatic HDTV timing for resolutions such as 1920x1080 @ 60 Hz and 1280x720 @ 60 Hz. If you need more slots for resolutions, add them in a CTA-861 extension block. HDMI also requires the HDMI data block in the CTA-861 extension block to go beyond 165 MHz pixel clock, but the TI TFP401 is a DVI receiver and doesn't officially support more than 165 MHz pixel clock anyway, so you don't actually need anything other than the resolutions. Then you can export the file.
