Ivan,

Are you using coreboot to run Windows 8.1?

For us HDMI is working with Windows 8.1 across wide variety of monitors and board samples.

Couple of things:

1) It's generally bad mailing list etiquette to have the legal footers on mailing lists, http://fedoraproject.org/wiki/Mailing_list_guidelines
has some good general guidelines

2) Are you seeing the lines during boot?  Once the OS is booted?
 - Are you using Gold 2 or Gold 3 of the FSP?
 - What Cables are you using?
 - What Monitor are you using
 - What OS drivers for the graphics are you using?
 - Do the lines show up when you do something specific or just in general (doesn't matter what's running)?

Adding Ivan, as he might have some insight.

- John
