Question External display support - Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40

Hi
I know that Mi11x will not support external display through usb type c hdmi cable.
Is it possible with any custom rom or a hardware issue?

There is no support for a External Display thru the USB-C connector,
you can always use Screen Cast if your TV supports it.

Your phone would have to support MHL (Mobile High Definition Link).
Alioth doesn't support it.

Yes you can with some cables like Mirascreen LD39, which doesn't need MHL support.

Use DisplayLink Adapter or Dock, works fine with most Xiaomi Devices

[Q] MHL HDMI without using power cable

Hi
I had a look at the MHL wiki;
"Samsung’s Galaxy S III/ Note 2 can power the MHL-HDMI adapter (when used with a non-MHL-compatible-TV). Although this can theoretically also be done with the standard 5-pin micro-USB connector, the Galaxy S III's 11-pin connector is believed to be the first smartphone that supports this functionality"
......does anyone know what this means? Can the Note II output the signal to HDMI without using external power.
We all know that it can connect to a regular HDMI socket but the adapter requires external power.
I know that when using a passive MHL cable it does not require power when connecting to a MHL specific HDMI socket. These cables are quite difficult (and expensive) to get hold of but Kanex does one. Furthermore, only very modern TV sets have a MHL specific HDMI socket.
After reading the wiki......I'm now wondering if the Note II can connect to a regular HDMI using a passive MHL cable without requiring external power.....but the wiki is not clear.
Anyone got any ideas?
I've just bought official S3/Note 2 MHL adapter and it doesn't work without external power source.
HDMI standard requires 4 TMDS wire pairs (R, G, B, CLK) plus additional control signals.
MHL uses a single wire pair for data, on which the R, G, B channels are multiplexed. That pair is shared by the USB OTG connection.
So my understanding is as follows:
In order to use a MHL passive cable, you need to have a MHL-enabled TV, and connect that câble on the MHL compatible HDMI port.
Otherwise, the TV won't recongnize the signals.
Currently most TVs are not MHL-enabled. So you need to use a bridge between the device MHL output port and the HDMI TV input, in order to convert the single multiplexed data pair in the 4 data pairs. And that requires powered.
The Question is why do we need an external power supply, instead of using directly the device power supply...
Too high power consumption ? Technical limitations with MHL v1.0 standard ? or No one would like to try that ? ...
Also, for you reference:
The Kanex cable you mention does only work with those MHL-enabled TV, as stated on the product page.
Samsung offers now a new MHL v2.0 adapter designed for the GS4:
http://www.samsung.com/us/mobile/cell-phones-accessories/ET-H10FAUWESTA
The new feature with that adpater is the fact that you do not need to connect the wall charger to it (unless you would like to charge the phone).
Although that is clearly stated on samsung's site that this adapter is compatible with GS3 and GN2, that is also clearly stated that only the GS4 supports this new capability because of its MHL v2.0 compliance.​

I couldn't 100% confirm that, but after some web searches, that has got clear for me now that it is a MHL v1.0 standard limitation.
MHL standard was derived from the HDMI standard, and was intended to allow a mobile device to send audio/video streams to a display device, while the display device can send basic control command to it. In addition, It was made possible to charge the mobile device thanks to the display device power supply.
So obviously, the standard was designed with a power supply provided by the display, not the phone.
And as for non MHL compatible display device, that seems it was not the first priority. Bridging between the phone MHL output and the standard TV HDMI input was a workaround, requiring an external power supply source.
With MHL v2.0, they have enhanced charging capability, and that seems they have covered the "bridging" case.
MHL v2.0 compliant phones (like GS4) should be able to power supply the bridge adapter. That tends to be confirmed by the fact that the new Samsung MHL adapter for the GS4, supporting v2.0 standard, does not require an external power supply if used with the GS4, but needs one if used with the GS3 or GN2.
Has anyone confirmed whether the Galaxy Note 3 will be MHL 2.0 compliant? I would guess yes, especially if the GS4 is already 2.0 compliant, but I just wanted to see if there was a confirmation of this anywhere. I would love to be able to display to HDTV without the need to separately plug in the power, because many times, the power outlet is not within easy reach of a monitor or HDTV.
I guess we will know for sure very shortly!
Confirmed: GN3 will have MHL 2.0, which should mean that we can connect the HDMI cable directly to the adapter without also having to plug in the power adapter. Woo!

USB C compatibility - HDMI?

Hey everyone,
I recently got a Nokia 6.1 aka 6 (2018) and was curious how good USB-C support is on current gen. Android phones.
So i tried using various USB-C adapters at home and at work to connect to different kinds of periphery in order to figure it out.
What worked for me:
Using my Dell USB-C adapter (DA-200) with Ethernet, HDMI, USB, VGA:
USB: works, can use mouse / usb drive / keyboard / audio interface, the usual USB OTG stuff
HDMI + VGA: not working, tried multiple displays, types of cables
Ethernet: Seems to kind of "work", powers up and LEDs on the interface signal an enabled uplink, however cannot configure the interface without root apparently
Using other various adapters ranging from USB-C to USB / Ethernet / HDMI / card reader to just USB-C to HDMI, i never was able to get HDMI working.
Now, it seems that there is a feature called "DP Alt mode" which i couldn't verify for any of the adapters i tested. It seems that the support for this mode is rather spotty among USB-C adapters.
Looking at the Qualcomm product brief for the 630 SoC, it seems to support "External Displays" and "DisplayPort". In contrast, the only thing the 835 SoC (which is confirmed to work with USB-C to HDMI adapters) lists additionally is "HDMI" support. (however it doesn't even list external display support, which is odd)
So i was wondering, is this what my adapters are missing to get HDMI to work?
And how can i figure out which phones even support video out using USB-C? DP Alt mode is never listed in the specs of any phone, and i don't know if it's in the SoC specs
IMO it is mostly a gimmick to be able to use HDMI with a phone nowadays, as other wireless screen sharing options work just fine for most use-cases, but i'm curious to see how cross-compatible this USB-C hardware is.
EDIT: just found out that apparently, in order to make a phone DP alt mode compatible, it has to support full USB 3.1 over USB-C, which the Nokia 6.1 apparently doesn't, according to spec sheets, it only supports USB 2.0 over USB-C. So i suppose it's not possible by the hardware design of the phone.
Did someone try a MHL adapter. They sometimes work on low spec phones. I sadly misplaced mine
Nokia 6.1 doesn't support wired video output (no MHL, no Alt-DP, no anything else).
The only option is the wireless standard Miracast (or the proprietary Chromecast).

I'm incredibly late to this, and this is one of my first posts, how does one get Miracast working on the Nokia 6.1? For reference I haven't gotten the phone yet (my parents are helping me to afford it and are giving it to me for Christmas).
I have tried usb c to gig ethernet and works automatic, it is based on the AX88179 chip it works in pixelexperience (possibly in the rest of roms)
(I know the topic is old but i leave it as a note)
How about this vod??

Hdmi screen mirroring via usb cable not working

Helped a friend buy this. We were watching movies via wireless screen sharing (miracast) and it was OK but kept stuttering and dropping WiFi.
So I suggested getting an hdmi usb-c cable with power charging (4k). I was very surprised when it didn't work! Tried everything including downloading dex to the phone.
Connected the same cable to my s8 plus and it worked beautifully (dex) !
So why not the Samsung a50? Never experienced this on any phone before and have been connecting to TV this way for 10 years.
Need a different /special cable? Or no go on this device and can only do via wireless?
Thx
I haven't ever used HDMI mirroring on a phone but as far as my knowledge of Type-C goes, you need USB 3.1 to support all the alternate modes including HDMI and DisplayPort. The A50 comes with USB 2.0, so there is no possibility of getting Display-Out from the USB port.

thanks for that explanation, I'm guessing this the same reason we can't use type c 3.5mm jacks?
by that respect, pretty much any type c 3.1 can output through hdmi?
Thanks,
Scott
Type-C as a standard is a mess. I don't think you are required to support alternate modes in USB 3.1, so I suppose there are USB 3.1 Type-C devices that still don't output video.
Regarding audio, there is Audio Accessory Mode for Type-C and the concept of active and passive headphones/dongles, so not all dongles will work.
samsung A50 simply doesnt support dex. only s8 s9 s10 and Note 8 9 10.
getting usb c to hdmi wouldnt solve your problem.
there is how ever one possible solution, which is the universal android usb to hdmi cable. it uses ezcast app (same app for wireless). mirroring your phone but wont display netflix etc on your tv.
Samsung A20
So, I know that the A-series doesn't support DeX, but I was hopeful that it might still have the capability to project to a lapdock (like the HP Elite X3 or Nexdock 2) via USB-C and display even crudely (so, not the fully optimized DeX-ified desktop mode, but maybe just a mirror?), ideally allowing for keyboard/touchpad input as well. Basically I'm trying to come up with a solution for my mom whose company is phasing out the laptop she's accustomed to working on in favor of these lousy Samsung A20s, which she's gonna have a lot of trouble seeing and interfacing with on such a tiny screen and without a full keyboard (she's in her 60s). The lapdock thing is the only idea I've been able to come up with (though, it sucks that the A20s don't support DeX), but I'm open to any other suggestions if you think the lapdock route is a dead end. Thanks!

The A50 doesn't support MHL(display out protocol) at all for some reason, which is quite disappointing. At least wireless display casting works well.

USB-C to HDMI Cable?

Any recommendations on a good USB-C to HDMI Cable? With Desktop Mode finally being an option in Q, I'm hoping to test it out when Q is officially released and we see some apps support it. Preferably with availability in the States.
Amazon basic have better option for this USB-C to HDMI, I'm using that work perfectly

Hi,
Does it work as HDMI + USB or only HDMI?
Is anyone able to screen mirror Netflix,YouTube TV, Hulu or Amazon prime with the cable? I have a cable and it mirrors everything except those apps when I'm playing video.

I don't want to maybe start a new thread so I thought here - does anyone charge their oneplus 7 pro type c from their laptop/pc to type c on their phone? my ultrabook doesn't quite have enough ports for usbs. so I wanna take away my phone on a usb and use a type c port instead to charge it.
I see some type c cables are 3.1 or something. for charging do I need the expensive cables?

I have an Aukey USB hub which seems to work great. HDMI and USB. It can charge my phone but that seems to be too slow to be useful.

You guys won't be able to mirror those apps unless you've rooted your phone and found a way to patch the application to make it think there is no secondary display connected. The reason you're getting nothing from these apps is they detect the presence of a secondary display, and since the phone cannot comply with HDCP over the adapter cable (not supported), it will not display correctly (black screen where the picture should be or no display at all). I've had a phone in the past with a miniHDMI port and I've used a proper mini-to-full HDMI cable without issue to watch Netflix, but that was a straight HDMI connection with HDCP. Netflix and them take anti-piracy seriously, yo!

Question Poco F3 support HDMI Alternate Mode (HDMI Alt Mode)

Would it be possible to use USB-C to HDMI adapter. And connect to the TV,? Does this
Phone support HDMI Alternate Mode (HDMI Alt Mode).
No HDMI available on the USB port (which is not USB3, BTW).
Thank you so I presume Chromecast is the Alternative.
I beliave that you can use the same cable I use on my poco F1, this one uses miracast screen transmission and works like a charm on lineage os 16 (android 9), but I thinks it works on any android os ios phone. Note that is only 30 fps, but with no lag, since it uses cable conection. Much better than chromecast thats uses wifi:

Miracast is not USB. Nor the F3 has any hardware to bridge video data over its USB2 port.
Show us your setup, please.

What makes you suggest the usb port is USB2?
