I’d also like to extend a hearty “fuck you” to whoever wrote the firmware Philips used in the controller for my monitor, because it’s impossible to use if you need to do anything BIOS or UEFI or apparently 9front-related due to the most aggressive auto-sleep behavior I’ve ever seen and can’t be disabled.

Kept thinking 9front or my Pi were broken, then I switched the HDMI cable to my HP Omen, and ta-da! Should that have made a difference? I don’t think so! But it did, and based on my experience with tinkering with various BSDs and Linux distros, this monitor’s refusal to care about output from UEFI / BIOS is a consistent problem. So I have to keep the other monitor around to access pre-OS consoles or settings.

Monitor auto-sleep is nemisis of trying to start a new bare-metal box in the homelab.

I have a older dell 1909W that juist bounces around a no-VGA dialog when one of the pins is floating. I have seen various hacks online about how to modify some monitors to prevent sleep mode.

I haven't gone down that rabbit hole, I just keep unplugging the VGA cord until a signal is displayed... at least that way i dont need to wait 5-10 seconds for the "going in to sleep mode" screens that can't be stopped.

I have heard of things like VGA splitters that output H/V signals regardless of the input, so the monitor is always on...

you can also look at EDID simulators if using DP or HDMI
