The whole situation around low-end server KVMs are a bit unfortunate IMO. BIOS can theoretically work with UART just fine, and not even full VGA@24bpp should be an absolute necessity for just confirming BSoD to decide to power cycle the machine, so it should be theoretically possible to be cheapened out a lot more to be e.g. telnet only or up to 5fps QVGA through HDMI-Composite adapter, or it could even be like a servo pointing an antenna to switch between different dummy load terminated VGA cables relying on TEMPEST techniques to get frames, for more potential cost and reliability gains.

I expected that kind of potato IP-KVMs to surface from crypto mining space, but alas, what we got was this thing which predecessor have reputation of crashing. That might not be stupid, but a bit frustrating.
