There's nothing to fix, the problem is patents. A true fix would be getting rid of HDMI and only supporting DP.
That'd be fine by me, if I could also actually buy a good TV that supports DP.
On the other hand, I also think it's bullshit that I pay for HDMI through both my GPU & TV, and the HDMI forum still denies me that bought functionality.
I imagine they make convert boxes. Could output the DP to one and then input that to the TV. But I'm still running a 720p Emerson TV so I probably don't know what I'm talking about.
Doesn't even need a box, I bet there are even just cables. One side DP, other side HDMI. And even DP -> DVI-D! Just guessing though, cause my old DVI-D-only server monitor is hooked up to the DP-only PC by magic.
DisplayPort out to HDMI in is generally easy to adapt with a cheap passive adapter, but going the other way is a huge pain.
I tried a DP to HDMI cable from JSAUX from my Deck to my TV (yeah, I know the dock got HDMI, I just wanted to try). It didn't work at all.
It's not known either way yet, but unless they offloaded it to a separate firmware like Nvidia or Intel, it's not possible for them to do in Linux due to HDMI patents. The way the other vendors avoided this is to use a separate component that does everything internally, so none of the code is in the drivers. AMD doesn't do that historically, and thus can only support such features with closed source drivers/OS.
Jep. People need to understand that HDMI is bad. You're literally paying for worse service. Just use DP. Open and better.
I mean, I agree. But I've waited long enough for a good OLED TV with DisplayPort. I don't get why they don't just add one.
Royalties. It's been 10 years since DP became capable of carrying audio on the same cable, so that's not an excuse anymore.
There are larger format monitors that have both, but I don't think they're configured in a way that makes them very cost effective.
TV manufacturers are part of the ~~cartel~~ HDMI forum, which benefits from there being a big ecosystem of non-member devices that are forced to have HDMI ln them and pay licensing fees for it.
Time for DP to be used on more devices, like TVs and such.
Theoretically they could avoid binary blobs by including a dedicated conversion chip on the board, and still using DP internally, but that adds production costs and makes things like freesync more challenging
displayport is dtill there hopefully
