your screenshot clearly shows HPD=0 and EDID=none on both hdmi portsHi, I’m experiencing a similar issue on my Raspberry Pi 5 (16GB). When I power it on, I see the bootloader screen, and it correctly detects the SD card. However, it gets stuck at that stage and doesn’t proceed to boot the OS. After a few seconds, the screen goes black and enters standby mode, and the Pi just sits there with the green LED on.
I’ve attached a photo of the bootloader output for reference. As you can see, it shows the SD card is detected and power supply is normal, but under display: it shows HPD=0 and EDID=none, which suggests it might not be detecting the monitor properly. I've tried two different HDMI monitors and a USB capture card — same result.
I’ve also:
Reflashed Raspberry Pi OS (64-bit and 32-bit) using Raspberry Pi Imager
Tried multiple SD cards
Performed an EEPROM recovery using the official bootloader recovery image (green screen + blinking LED showed success)
Despite that, I still get stuck at the same bootloader screen and no further boot. Would really appreciate any help or thoughts on whether this could be a display detection issue or something deeper.
Thanks!
when linux sees that, it will assume no monitor is plugged in, and then produce no video signal
something is probably wrong with your cable or display, but adding a video= to cmdline.txt may fix it
