I flashed my Beaglebone Black with the latest Debian image and to my surprise, the HDMI resolution is 1600x900@60Hz (max. for the monitor I’m using).
I was under the impression that the hardware limitation of the BBB was 1280x1024 due to the 125MHz pixel clock. That was the case while running Angstrom or Ubuntu.
Has something changed? The colors do look 18-bit-ish but I’m not sure what is was before at 1280x1024.
