With some limitations, it will take the list of modelines in the EDID (which, mind you, might be just VIC id's), and compare it to what it believes the hw capabilities are, and pass through only that list of modelines that it thinks the hw will generate. This is what you should see in the xrandr --verbose list. For HDMI, we currently have a hack to allow up to 297MHz pixel clocks for Kepler+ GPUs. However for HDMI 2.0, I think there's some more stuff. And it's not clear that we're parsing the capabilities correctly on such GPUs. > The main wiki page probably ought to say what subsets of HDMI nouveau > supports.

If you have concrete suggestions for improving any specific page, I'd be happy to make the edits for you. Unfortunately many parts of the wiki are "too far gone" so to speak, in terms of inaccuracy/incompleteness.
