    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…
