Re: Low display resolution (800x480) and low display pixel clock
Hello,
The displays and all other peripherals are handled by Raspberry Pi OS and the kernel. Hudiy is just a UI application that runs much higher in the stack than the kernel and drivers, and it relies on mechanisms provided by the operating system.
Unfortunately, we’re not able to provide such detailed information. On Raspberry Pi OS Bookworm, many HDMI settings are now deprecated and are handled directly by the KMS/Mesa driver.
From what we know, KMS relies on EDID (Extended Display Identification Data) to choose the correct display parameters. According to the Raspberry Pi documentation, it’s possible to load a custom EDID file, which can be useful when working with non-standard displays.
The best option would be to post your question on the Raspberry Pi forum: https://forums.raspberrypi.com/
