Thanks for the information ! I was just googling and found this post: https://www.eevblog.com/forum/projects/(help)-hdmi-2-0-to-mipi-dsi-lvds/msg1072821/?PHPSESSID=rtlfev18pveu5c690gmq2jis7a#msg1072821
which indeed states the same thing, the novatek NT35950 driver chip, which is indeed also used for our panel, supports DSC and qualcomm's FBC compression technology.
I'm not sure what you mean though when you say "the team is seeking collaboration with other chip vendors ". Do you imply that you want to change the driver chip for the panel ?
Also I'm not sure what you mean with "the graphics card（NVIDIA or AMD）couldn't support the Qualcomm FBC 2.0 or VESA DSC 1.1 tech.". Is that really COULD not, or are they unwilling to do so ? Did they explain ?
Because if they could, but weren't willing, then there's at least the theoretical possibility to get it going via some hack.
I don't know much about HDMI at all (I'm a quick learner though and that's how I pretty much always start a new adventure anyway, 0 knowledge about the subject and ending up as an expert ). But I think it should be possible, because NVIDIA did something like this in the past already:
So the HDMI protocol does seem to support compressed data. Hence I wonder: did NVIDIA/AMD explain why they can't support it ? Or where they simply unwilling ?
On that first forum post it says that the DSC standard is open source (for a $300 fee). So If it's possible, then we'd need to hack our way in. We'd need to see if it's possible to hook into the NVIDIA/AMD drivers and see if we could modify (compress) the data before sending it. Or maybe have the drivers deliver the data to our own driver which then pushes the compressed data over HDMI.
Again, I'm just speculating here with 0 knowledge about HDMI, I'd need to read up on it, maybe it's not even possible.
But if it is: My hobby is reverse engineering stuff as you might have figured out I did some work on the Galaxy Note 4, where I reverse engineered Samsung's camera closed code drivers and ported that to open source code and I did work on some gaming consoles and mediaplayers, so I have quite a bit of experience hacking/reverse engineering code.
So who knows, maybe we can figure something out to get it going ?
