Have you updated your firmware using the rpi imager?

no luck with that 2.9.1

It prints a few lines of text in the upper left, then the HDMI signal dies and the monitor goes to sleep.  It's not booted and not responsive to keyboard

Both RPI4s I have, burned with RPi imager and "no" to customizations

You can try this version, which I've verified works on both the Raspberry Pi4 and the 400

OK, I have something else going on, but I can't figure out what.
I've got 2 RPi4B here, 2x new 64GB Sandisks from Amazon, and one older one that put a LinuxCNC image on about a year ago, which booted some text but said "this board requires newer software" and kept repeating that. I'm using HDMI0

The old card still booted to "this board requires newer software".

But I made up a card for the regular RPi OS 64 bit. That did NOT boot either! OK... so...
Power supply? changed to two other power supplies, including my Dell laptop USB-C supply. No diff.
PC? That would make some sense, but I reprogrammed the card on a different PC. No diff.
Bad SDHC card? That we're dealing with 3 different cards acting the same makes that implausible.

There's clearly a problem here if I can't boot a regular image. But as far as I can tell I've ruled out everything but the monitor.

Did you look into upgrading the RPi firmware\bootloader ?

Aw crap, it IS the monitor. Well, HDMI cable
