Getting MHL/HDMI video out to work

I have both a genuine Samsung MHL adapter and the S2 mhl adapter with the 5pin to 11pin converter and I've seen both of these work on other phones.
However, I can't get my video out working on my S3. Both of them connect and bring up active charge and indicate onscreen that "HDMI cable connected". So I know the adapter and cable is being detected but no signal on HDTV. The HDMI cable is good as is TV and monitor I tested on and of course proper input is selected.
Now as far as I remember as soon as it is plugged in the video should automatically show up on HDTV screen...correct? No TV out setting has to be turned on as in past Galaxy correct?
Fyi..I have multiple S3's but currently only have one on hand...its a 747m with KyanROM on it... so not stock..it is rooted and has KT747 9-18 kernel as well.
I have a feeling its the rom(and I could easily test this if I had other phones but don't for a while).
So if both MHL adapters are confirmed working and both the HDMI cable and TV are working AND even the phone states that HDMI cable connected, then what is the issue with no video display?

Do you have the power plugged in? That is, a AC/DC charger to micro-USB cable plugged in to the micro-USB port on the adapter.

Should work automatically
I just received the Min-Suit 11-pin adapter sold on Amazon. Mine switches on automatically as soon as I plug in the adapter. Of course, to make it work, you should first plug a charging cable into the USB micro port on the adapter and you should connect an HDMI cable to the tv. Also, make sure you're selected the correct HDMI input on the tv. If you do all of that, the picture and sound should start up as soon as you plug in the cable.

Unless it was a mistake, your OP says you have s2 adapter. From my understanding, the pins are different on the s3 and will not work with the older adapters.

If you read closer Woody you will see that he says that he uses an old MHL adapter, WITH the 5 to 11 pin adapter
That should work. But I think your ROM is the guilty one...

Dont give up yet, I thought I had the same problem, but my ballistic case was preventing the MHL adapter from going all the way in. I took the phone out of the case and the adapter clicked in. Worked great on the TV, but best of all, worked in the truck via a down converter. Had to play with it to get in deep enough (kind of phone foreplay i guess:laugh to work, but it does.

thanks fr reply. but i didnt get you how to make it work?

The note 2 and the s3 have different hml adapters. You will also need a converter.
On the monoprice link you posted, youll notice ab asterisk next to the s3. Same applies to the note 2.

I just got a Samsung HDTV Adapter Tip (5 to 11 Pin) Model EPL-FU10BEBSTD, which has micro-USB female to male; it enabled my TMobile "HDMI connection kit" that had worked with Galaxy S2 Hercules to work now with my Galaxy Note II. The connection kit was expensive, but has a 10' cable from the MHL adapter body to the male micro-usb plug, as well as a 5' cable to the TV HDMI, and a wall charger to power the adapter body. So the arrangement is quite flexible once installed.

I was hoping someone could help me with this problem also. I have a hdmi capable monitor that I would like to hook my note2 up to but for whatever reason the monitor will not detect the signal. i have tried rebooting and connecting it various ways but no dice.
the only thing i can think of is that its the rom im using which is myrom's latest version

Do you have 5pin or 11pin mhl cable? Note2 requires 11pin one.

I was told you need an S3 cable. Here's the one I use.

Yea you guys are right you need 11 pin for the note 2. the sgs2 used 5 pin so if you have one for your older phone you need a new one or I think they make a converter too. I would suggest getting right from samsung. it may cost more but you get what you pay for usually and samsung makes the best stuff when it comes to that. Also another thing to consider while you are on samsungs website they have a multimedia dock that is on backorder right now but for a 100 dollars it turns your note2 into a pc basically. It has 3 full size usb ports so you can hook up a mouse keyboard and external hard drive and it has the hdmi port and an auido port so you can hook it up to a hdmi tv/ monitor and multimedia speaker system. I was going to get a new computer but I found this thing. So basically I can have an android desktop. It dont get better than that. Now wit dropbox and mobile odin and this exynos exploit we really dont need to hook up to a pc to root so there is no real reason for it. Just something to think about.

This is really helpful. My question is will this charge your phone while you are connected to the tv? Also, I see some of the description on ebay says it might not work if you are rooted.

I am rooted; The MHL/HDMI system works well, if that is your concern. The charger that I use for the MHL adapter is much lower amperage than the one that came with the Galaxy Note 2, so I would guess that charging might be slow if you are watching a movie that way, or maybe not even keep up, but I don't have the patience to do the test (or watch movies that way).

Hmmmm!!!!
I just got the Samsung dock and can't connect with HDMI on rooted stock.
The phone detects the dock and charges up, but no signal to the screen. Also tried hooking it up with the TV and projector using two different custom rom and separate HDMI cables and no dice.
Guess the dock is defective.

Hdmi Dock

Is there a dock that charges and does hdmi out? Thinking this would be cool to play emulators or GTA on my big screen, paired with a wiimote or ps3 controller

To connect to the a TV you will need an MHL to HDMI adapter like this. I'm not sure if it charges at the same time, but it should, being that it connects via the USB port on the phone. If you search around the web, you'll definitely find much affordable deals. Cheers!

at least, if not charge, it maintains the charge level.
from your link:
The HDTV Smart Adapter supports HD signals up to 1080p. Connects directly to a standard HDMI cable for easy connectivity to home theater or monitor. Requires power from a wall charger. Can connect directly to your MHL-Enabled mobile phone to create an HDMI docking station. Requires wall charger (sold separately) to power the adapter while in use. (HDMI cable not included)”

There are some other brands, more afordable. Have any one tested any of them?

another question, can I connect a usb controller and still charge the phone and have it output to tv or am I too wishful in my thinking

You cannot connect more than one USB cable to your phone, so unfortunately that is not possible. Which controller exactly do you need to connect to your phone?
If by any chance you are planning to use a PS3 controller, pairing it with your phone through Bluetooth and using the Six Axis Controller app is the best way to go.
Edit: In that way, you will still be able to connect the phone to your TV via the MHL cable

if you hsve a frys electronics in your town, they have this item for $24. WORKS WELL.

HDMI/MHL Video Output

A new monitor of mine came with a cable. One side fits an HDMI port and the other side fits my phone's microUSB/MHL port. The cable says "MHL" on it. Therefore, I thought it would allow me to output video from my phone to a monitor/TV, but it doesn't work. When I plug in both ends, my phone's red light comes on like it's charging and there is no signal received by the monitor.
Are there settings I need to change on my phone? Is this apparent MHL to HDMI cable not what I understand it to be? Thanks for any answers.

What's the model of your phone?
If you really wanna output video from your phone to a monitor/TV, you can order a MHL to HDMI adapter from Samung online store or ebay/amazon.

My phone is an SGH-T999 (T-Mobile Galaxy S3). I'm sure I could get the official adapter from Samsung, but I'm wondering why the one I have does not work since it appears to be MHL to HDMI. Do I need to check the number of pins? How? Are there any special settings I have to make on the phone or should it just plug and play?

You could look for a 5 pin to 11 pin hdmi adapter for the s3 (around 2$), this could make it work fine

When i connect my MHL to HDMI adaptor, my first step is changing the TV signal mode to HDMI signal Mode before i plug it to HDMI port, please give it a try. I don't think it just plug and play if you turn on your TV as normal for watching TV play. Your have to change the mode first.

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!

Recommend an adapter with a power plug in so your phone doesn't run out of juice while watching TV.
