It doesn't work at all.
I tested all 3 available firmware versions (all versions from 1.0.0 to 1.0.2). There is no video signal (HDMI). I tested it on two monitors: a very old NEC (professional series) and a Philips (not very old).
The board is a Waveshare RP2350B-PiZero (no PSRAM, 520 KB).
HDMI signal output issues occur VERY FREQUENTLY across various firmware versions. I found one explanation: the firmware's operating frequency is directly linked to the display's refresh rate.
For example, with this firmware:
https://github.com/drewpo28/pico-spec/releases (v.1.2.22)
my board works at the following resolutions:
640x480 @ 50 Hz
640x480 @ 60 Hz
720x480 @ 60 Hz
720x576 @ 50 Hz
THIS MODE DOES NOT WORK!!!
XXX 720x576 @ 60 Hz XXX
Other refresh rates like 70/72/75 Hz might not be supported by the monitors or might not work correctly with this board.
