Reduced Blanking v3

[haarp]

Hi,

it seems that a new version of reduced blanking has been released. I cannot find much information about it, apart from some commits (esok/edid-decode@e908154)

Might be worth implementing? I'm always up for getting more out of existing links :) Assuming we can find the official specs. Either in CEA-861-H or CVT 1.2 Errata E1.

Cheers!

Hi @haarp, thanks for the information, I'll try to see if I can get more information from the VESA website, I looked into it a few months ago but they gated it by requiring personal information so I didn't proceed further, perhaps there's more information available publicly now.

fyi, CTA-861-H is since available for free (still requires registration tho) here: https://shop.cta.tech/products/a-dtv-profile-for-uncompressed-high-speed-digital-interfaces-cta-861-h

From a quick glance, I see some mentions of RB3 in the document, but not much about timings.

I have also seen mentions of CVT 2.0 floating around but I couldn't find anything specific.

libxcvt has seemingly added RBv2 and v3: https://gitlab.freedesktop.org/xorg/lib/libxcvt/-/merge_requests/11/commits

I do wonder if that removes the need for separate tools.

That's just a PR actually, and even some tentative one presumably.
