Any news of a firm future to enable video output?
that will depend on whether or not to sell my Zero.
You're asking if a firm or company will work on HDMI out support ?
Nah, this is not going to happen, especially since the GCW Zero is met with supply issues.
It is (and was from the beginning) entirely supported by a few people in the community.
It was never backed by a company and no employees were hired, unlike what Justin said.
With Justin having family issues (or so i heard), don't expect anything from him.
Like it was said a billion times, they'll try to merge some GCW Zero changes to upstream.
(like it was done for the Raspberry PI, Nexus 5 etc...)
However, this depend on the good willing of the maintainers accepting the changes.
Plus, the maintainers made some changes to accepting DRM patches, this could further
delay accepting the changes. (however, i think that it's mostly unaffected by that, need to check)
And no one reversed engineered the HDMI out in the vivante.TLDR;
not going to happen any time soon. You can put your GCW0 on Ebay
