  Nope, but it should be viable. Modern HDMI monitors are often flexible on timings. Using minimum dot clock and blanking nets: 25 MHz / (1280 + 80 = 1360) / (400 + 20 = 420) = 43.8 Hz refresh.

  And of course they have scan converters built in so can accept lower resolution timings too. Ie: I'd expect 640x400, amongst others, to also work.

  Thanks. I guess we'll find out. I have one on the way.
  I only just discovered those little 10" racks for mounting gear. seems like a perfect little flexible electronic testbench setup.

  10” rack? Don’t think have seen that before…

  All ours are 19”.
  Maybe could get two of those side by side on 19” rack…

  seems to be serving the Pi and other SBC mini-PC home network market with a variety of useful interchangable parts.
  P2 edge, I'd consider, is an SBC sized device with a clutter of interconnects and reconfiguration needs strewn about my bench un-manageabley at the moment. will certainly share how it comes out
