MHL /HDMI ( or any cable display sjaring) - Xiaomi Mi Note 3 Questions & Answers

So according to the snapdragon 660 spec, the maximum external display support is 4k, and on mhltech.org is stated that the MHL doesn't require usb 3.1 (MHL Alt Mode over USB Type-C™ enables MHL video up to 8K and immersive audio concurrently with USB 2.0 and/or USB 3.1 Gen 1 or Gen 2 data.)
Does anyone know if it is possible to to add such functionality to our device via custom rom or any other way?
Also i've seen some screenshots, that show more options in the "pie" update, that are missing atm, like aptX support. Do you know if mhl is existing in the new software?

Add MHL support in Mi4i using custom Kernel / Use Mi4i PCB as a development board

Hi guys
So i have a space Mi4i with non working touch and is broke too, so i want to use it as a media center, but i am having following problems.
Case 1:
Mi4i does not support MHL, so i can not connect it to tv directly. (don't want to use chromecast want to use the board itself as a media center)
I found that the stock kernel source contains drivers for MHL and there were other libs too in kernel related to MHL. So is there option if can compile a custom kernel and add MHL support into it, does the phone contain specific hardware for MHL.
Kernel has driver for sii8334 chip, which is capable of 1080p HDMI output
Case 2:
Is there a possibility if a cable or something which converts the output from PCB's lcd port to HDMI? i.e the cable will connect to PCB's 30pin FPC port and give output as HDMI.
Is it possible?
Its fairly powerful board and can turn a normal tv into smart tv for me, please guide.

USB C Adapter / Hubs [HDMI/DP/VGA, Gigabit Ethernet, USB 3.0, PD, SD/TF Card]

Hey guys, I'm trying to set up a collection of knowledge about USB C Hubs for the Xperia 1.
Has anyone tested those yet? I want to expand this thread as more information is gathered.
Ethernet and USB Cameras don't seem to be supported at all.
So far i tested these ones.

I've used Dell Universal Dock - D6000, it mirrors the screen and charges at the same time, using the DisplayLink Desktop (Demo) App and SecondScreen to adjust the resolution, I had a few suggestions for SecondScreen such as checking the resolution after connection and creating a new profile at connection time and then being able to re-map the profile if you accidentally connect in portrait instead of landscape, but so far no reply.
Ethernet doesn't work.
Video and audio works well, but the DRM prevented me using it to watch Netflix on a TV in a hotel room whilst on a work trip, the movie or show video isn't played, but the rest of the GUI is displayed including preview videos with audio. Strangely it works fine on PC on the same Dock, shrug, I'd figure that's where you would rip the video if you were going to. I guess it's OK though as the ChromeCast doesn't have the same DRM concerns, so I should just buy one of those perhaps. (unless someone could fix this ).

Damn that's ridiculous. The normal xperia 1 sold for over 1000$ and now they introduce the Sony Xperia 1 Professional Edition with ethernet. Thats only a few drivers added to the kernel. Other smartphones for 150$ can do that, but sony has to be special about it.
Sony Xperia 1 support Ethernet with ThinkPad Hybrid USB-C dock: https://support.lenovo.com/us/en/solutions/pd500180
Out of curiosity, i tested my old adapter again. For some reason it is working now, Sony probably added more drivers in a later update.

List of devices with video signal via usb.

Dear forum.
Android phones are great laptop replacement but requires a wired monitor signal for persistence. Wireless screencasting tend to lag or disconnect after a couple of hours usage with bluetooth keyboard/mouse interfering with wifi so for repeated work you need a wired monitor signal.
By setting screen width to 4-500pixels in settings/developer options and using utility apps such as taskbar pc-style, leena desktop or sentio your phone becomes a highly usable desktop computer if connected to any tv, projector or monitor with hdmi capacity. Add to this a phones superior microphone for commands and voice to text funtion in google dox. Trouble is to find a phone with verified video capacity over usb, there are several standards and lots of rumors so Im hoping we may create a reference list of known devices with known capacity of video over usb with the good help of you folks.
Main Technology standards:
The two main tech standards are MHL and Displayport. MHL was early available on sony, samsung, LG and more devices via microusb ver 2. Displayport has grown later years with Huawei/Samsung devices over usb c ver 3. The older MHL over usb ver2 have difficulties handling more than video and sound, some devices such as sony Z5 may charge battery slowly when connected on MHL to external usb power but no guarantees. MHL over usb ver 2 have no capacity for keyboard/mouse or ethernet via usb, these must be connected via bluetooth.
Later usb ver 3 standard have capacity of video, sound, power and data, these devices can be connected to a hub with hdmi, keyboard, mouse, ethernet and still charge battery. There is plenty more to add about technology but lets keep to most basic info and focus on a list of devices with video signal over usb as I have not been able finding a complete list anywhere.
- There is also extra hardware available such as Displaylink which requires an app and displaylink chipped hubs but there is little information available so hopefully someone chips in with better info and proof of concept.
- There is windows phones with hdmi capability but I dont dare to mention so please contribute.
- Apple phones may have hdmi capability but there seem to be much rumors and guesswork without exact knowledge so please chip in if you have knowledge on this part.
- Several names/words are used referencing the function of connecting phone to external monitor. Samsung referencing as "Dex", Huawei "desktop mode", windows continuum, wired screencast, MHL, displayport, hdmi over usb,
All help completing the list is higly appreciated, please see this list as a suggestion this far while being completed/updated, the aim is to have a complete reference list of computer capable devices using the collective knowledge in this forum.
List of devices :
MHL, 5-pin microusb ver2 please see link att bottom for detialed list :
Samsung Galaxy 2/3/4/5/6
Samsung Galaxy Note 3
Sony Z3/Z4/Z5
Sony Z ultra

Enabling multi-touch on Fire TV & Google TV

Hi all,
My goal is to to connect Fire TV and Chromecast devices to touchscreen displays, interacting with them similar to Android phones. I had hoped that touch input would be available out of the box but that is not the case. After much searching, it seems that touch input drivers are not included with either Fire OS or Google TV. Getting touch input working may require compiling the HID-Multitouch drivers and loading them into the kernels of Fire OS and Google TV.
I have some experience compiling from source on Linux, for Linux devices. I have no experience compiling from source for Android, Fire OS, or Google TV.
Questions:
Has anyone gotten touch to work on these devices?
Would a pre-compiled kernel module for Linux or Android work with Fire OS and Google TV kernels or do the drivers need to be compiled specifically for these devices?
If compiling specifically for these devices is required, what is the best approach be for someone who has never compiled anything for those devices before?
Desired state is a device that can connect to portable touchscreens via single USB connection and do not require additional devices (remotes) for user interaction.
The Zenscreen that I'm currently using supports HDMI input and touch output over USB-C but the monitor isn't capable of reverse charging. As a result, the USB-C hubs are needed in order to provide power to the Fire TV and Chromecast. If touch can be made to function practically the Zenscreen will be replaced with a portable touchscreen that supports reverse - possibly the 4K Uperfect.
Fire Stick is not capable of connecting via single USB port due to the limitations of the USB v2.0 Micro-USB port. It will require HDMI and USB cables to be connected to operate with touch.
Chromecast USB-C port capabilities are unclear and the USB version is not listed by Google. The device does not output HDMI over USB-C out of the box and I haven't determined whether that is due to software or hardware limitations.
Both devices output HDMI to the Zenscreen with the GQeeM HDMI to Micro-HDMI adapter and both devices accept power from the dockteck hub. The Fire TV also accepts power from the Apple hub.
The order of connection is USB-C charger --> USB-C hub --> (Chromecast or Fire Stick) --> HDMI to Micro-HDMI --> Zenscreen (via Micro-HDMI).
HID-Multitouch is connected to the hubs from the Zenscreen's USB-C port through a USB-A to USB-C cable.
Problems
Fire Stick and the Chromecast both fail to recognize the HID-Multitouch input device.
Chromecast complains about power from the Apple hub. Apple doesn't publish the power output specifications. According to this (unrelated) article the Apple hub should be capable of negotiating 7.5w (5v @ 1.5) output but there seems to be a problem with the negotiation and it's likely that the Chromecast is only receiving 5w (5v @ 1a).
Zenscreen was connected to laptop using the Micro-HDMI port and a USB-C cable in order to validate that the monitor outputs touch commands over USB-C while the Micro-HDMI input is active.
Devices & Versions
Fire TV Stick 4K: Fire OS 6.2.8.0 (NS6280/3233)
Chromecast w/ Google TV: Build Number: 210311.008 7350836

Hi!
Have you been able to connect the touchscreen to the Chromecast with Google Tv?
I’m having the same issue…

I need an android device with some oddly specific requirements

I need an android device with
- arm64 app support
- Android 7.1+
- Separate HDMI and USB ports
- Preferably more than 2GB of ram
It can be any sort of device (tablet, tv box, SBC, etc.) but the USB port *must* fully support usb accessory mode (what Android Auto uses). I already tried a Raspberry Pi 4 with KonstaKang's ROM on it but accessory mode wasn't working right. My end goal is to install the DJI Fly app on the device so I can connect my drone remote to it and have the video from it on a big screen without the latency that comes with casting over wifi. The remote acts like a usb host and triggers accessory mode so that's why I need a separate HDMI port.
