I'm sorry I didn't realise it was merged, apologise on my part. Thank you Koen and Robert. I've also cleared my comments to avoid confusing others. New to GitHub pull requests!

Coming back to the issue, Koen can you try different monitors? Also what beaglebone rev is this? Do you see a pixclk signal on the expansion header? I tried 3 monitors here and all work.

The part that stands out in the past about is that it is using a 92mhz pixclock instead of the 72 needed for 720p60
