Bounty 100 EUR - Displayport Alt Mode - Enable USB C to HDMI

[Inerent]

Hi, Andro,
Please look into BoardConfig.mk... you are the man and have the experience and I will try to make that bounty higher
P. S. Just give me a sign that you are willing to look into this please!

Here is my list with Sd835 supporting Displayport alt mode after googleing many night on forums:
Samsung S8, N8, S8+, LG v30, Razer, Essential Phone

for devs ... read here:

and here:

There are 4 modes for Type-C DP alt mode:
1) USB host only :

extcon_set_cable_state(edev, EXTCON_USB_HOST, 1);
extcon_set_cable_state(edev, EXTCON_USB, 0);
extcon_set_cable_state(edev, EXTCON_DISP_DP, 0);

2) USB device only

extcon_set_cable_state(edev, EXTCON_USB_HOST, 0);
extcon_set_cable_state(edev, EXTCON_USB, 1);
extcon_set_cable_state(edev, EXTCON_DISP_DP, 0);

3) DP only

extcon_set_cable_state(edev, EXTCON_USB_HOST, 0);
extcon_set_cable_state(edev, EXTCON_USB, 0);
extcon_set_cable_state(edev, EXTCON_DISP_DP, 1);

4) USB + DP

extcon_set_cable_state(edev, EXTCON_USB_HOST, 1);
extcon_set_cable_state(edev, EXTCON_USB, 0);
extcon_set_cable_state(edev, EXTCON_DISP_DP, 1);

we need to write the code from 4. (1,0,1)

I had no idea that the Razer phone had displayport alt mode. Good to know.

I think this value needs to be changed un build.prop:
ro.usb.pid_suffix=1F1

Hello
Yes we know that, but seems like Sony has disabled it in kernel, or did not write the code to enable it.
I will buy a 3.1 usb c hdmi cable to convince myself... :good: maybe it was the cable. Indeed we have usb-c 3.1 with 10gbps speed so we must test with this cable...

What's the outcome for xz premium usb c to hdmi cheers

EDIT:

After extensive research and taking no for an answer I think I found the solution and It works!

Show me the proof.
Make a YouTube video of it

 

[Inerent]

As you can read in my posts, this can be achieved with displaylink hardware, but only in 1080p, not in 4k. Therefore no bounty for extra hardware which is not 4k capable.

 

[fbloise]

That’s correct, can be achieved via displaylink hardware

 

[Inerent]

Seems that we now have 4k60Hz display link technology available ... but for windows. it doesn't say anything about android/linux arm machines.
