Hi all! This topic gathers users with HDMI issues on their UDOO, typically a blank black screen or, in few cases, wrong sizing. I want to let you know that the team is working to solve and patch these issues, where possible (read: software related issues). If your are experiencing problems with the HDMI output, follow our troubleshooting procedure: How can I solve my HDMI issues? If you need more help please post the results here before asking for support so we can better understand what's going on with your UDOO.
