(Q) can I use MHL HDMI adapter via 30 pin galaxy tab to micro USB adapter

Hi ,
I wanted to use my galaxy s2 MicroUsb HDMI MHL adapter and OTG USB cable with Galaxy tab "7" with this 30 pin galaxy tab to micro USB adapter.
Any help regarding usb host and hdmi capabilities will be appreciated.
HDMI is supported via Samsung Media Dock. Could have googled for that. There is no listed USB OTG support listed for it, but there is a Keyboard for it, which could be indicative of UDB OTG support, at least of a proprietary nature. Both of these accessories require the standard charging cable to provide power during use.

I bought Mhl adapter because i was going to buy galaxy note. Then at the last moment i changed my mind and bought galaxy tab 7 t-mobile. My media dock as also arrived. But still waiting for 30 pin con to mic usb adapter and mini hdmi to hdmi adapter. I will let every body know if any thing is discovered.

As it stands, HDMI is available through the Dock as mentioned, but there is no USB OTG support. Keyboards can be connected to the 30-pin (Samsung keyboard) or through Bluetooth (third-party keyboards).
There was a project to get USB Host support going, but it seems to have stopped. You can try the OTG gear since there are many variants of Tab and many ROMs etc, but I don't think you'll get anywhere with them since the stock software doesn't seem to support anything apart from the Samsung official accessories.
I am working on getting USB OTG working, but it wont happen anytime soon.
You cant just plug in anything that fits and expect it to work. The Galaxy Tab 10.1 30-pin to USB and 30-pin to SD are for that device.
so in conclusion, it never work?
I was thinking of using OTG + USB to RCA cable rather than HDMI...
I am using GT 7.0 plus
see if someone can answer?
is the OTG P1000 USB working on the plus model?
thks!

[Q] Does anyone know of any video out cords to standard av port for the galaxy note

i am trying to connect my galaxy note to my Infiniti g37 nav screen which has standard av input i was able to do this with my previous jail broken iphone but i have not been able to find any cords that will plug into mhl for standard av. Does anybody know of a way to do this or a place i can buy this type of cord i have seen a way to do a lengthy conversion process with mhl to hdmi out, hdmi to av converter box ,av cables to video in, but that's allot of cordage to try to squeeze into my center console and none of the converter boxes connect to car power port and would require an additional power adapter. so again to restate im looking for an easy way to connect my note to for video out to my av in device

OnePlus 3T out video to monitor via hdmi

I want to connect a 27 inch monitor or projector.
From the official support says (ticket #770598, from Sky) that phone 3T supports out video via HDMI
I understand that you wanted to know if OnePlus 3T supporte USB to HDMI. I can provide you with the information that you needed.
I would like to inform you that OnePlus 3T supports HDMI as long as it is connected to the OTG cable/ converter.

1. This phone is really support hdmi alt mode? I don't see the image HDMI (or DisplayPort or Thunderbolt) alternat mode on the box.
2. If (1) is true. Any cable good for me? Ex. usb type c multiport adapter from apple store or necessarily with OTG?
3. How big is the latency video of through miracast (ex. ezcast)? If connect mouse and watch on cursor movement.

Thans for the reply
I think they sold me a dud
Phone not supports MHL and other alt. mode
II wonder if a driver could be put into a ROM to support it via USB OTG since it doesn't support MHL?
I have an old external sound card, a Creative Xmod, that works perfectly with my roommates USB C, OTG adaptor.

I think because it is not implemented in hardware in the phone
If I'm correct Display Port alternate output requires USB Type-C 3.1 since the phone supports only 2.0 it shouldn't work. However not many phones utilise this feature even Google Pixel doesn't use this mode
Video out works fine on the 3T but only with Displaylink adapters. (So far anyway)
I have one and can confirm it definitely works either via HDMI or HDMI to DVI (I've tried both)
I used this one: https://www.amazon.com/gp/product/B01N40RQV4/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1
but any displaylink adapter or dock will work. (Make sure it very specifically says dispaylink, check the displaylink website if you aren't sure)
The only note is that displaylink says the Ethernet ports on the docks do not work with android.
(I suspect they might work on devices that support a regular Ethernet adapter though, I haven't been able to get a normal Ethernet adapter working on my oneplus 3t though for what that's worth.)
you will also need the displaylink app from the playstore though it does not have to be running.
if any of you have experience using an external Audio DAC with USB Audioplayer pro the process is very similar.
Once you plug the monitor in, a pop up will ask if you want to let the displaylink app control the adapter and if you hit "ok" it does the rest automatically.
Does the phone charge while connected to the DisplayLink adapter?
Just try with Chromecast or anything else with Mirascreen option
Does it work with Anker Premium USB-C Mini-Dock
Hi there everybody:
Have anyone tried to connect a dock like the Anker Premium USB-C Mini-Dock, Does OP3T work for charge and to view the USB ports of the dock? May be HDMI and Ethernet doesn't work but for me the matter is the chargue and the USB ports to connect an external DAC, a microsd and a pendrive. Regards.
