[Q] Mhl and HDMI trouble - Xperia Z2 Q&A, Help & Troubleshooting

I've bought a cheap mhl cable and I can output my phone to my TV, but it only does 1080p at 30hz.
Does anyone know how to change this?
I would much rather have a lower resolution but 60hz refresh.
I'm currently using cyanogenmod, but can't see any settings for mhl or hdmi.
Also, what happened to mhl 3.0?

How did you get the output to work, tried with an mhl cable I have but got no picture

I simply plugged the hdmi cable into the mhl, a USB charger into the mhl and then the mhl into the USB port on the phone. The display duplicated instantly. No problems with it working straight away, just dipped to 30hz on screen and was REALLY laggy.

[Q] MHL cable compatability?

I just found a MHL cable for the SGS2 on Amazon with Micro-USB to HDMI.
I have a Samsung HDTV bought about a year ago. Now i know that MHL means you can charge as well as view the phone stuff on the screen but MHL TVs have not released yet (i think, and even if they have i wont be getting one anytime soon).
So my question is can i still see the TV out if i use the MHL cable on my older TV? I know it definitely wont charge.
Anyone?? :S
yes you can.
all you need is the adapter from MHL (micro-USB) to HDMI, connect the HDMI to the TV and you are good to go.
the advantage of the original samsung adapter is the ability to connect a power cable to the adaptor and charge the phone while it transmits the picture to the TV.
hope i helped
Thanks mate
For anyone confused, an MHL cable is a Micro USB to HDMI cable - no ifs, no buts, this will transmit HDMI from a compatible MHL port. Nothing else needed (except I believe it must also be connected to power)
Your micro USB port on the bottom of your SGS2 is an MHL/USB port, and will therefore work.
Important to note is that not all micro USB ports are also MHL ports, therefore will not necessarily work on some other micro USB port on a different phone.

[Q] Micro USB to HDMI

Does anybody have any info on when this cable will be available? I was also wondering if anyone knows if I can play the 3D Movie from my phone on my 3D T.V. with this cable.
I don't have a 3D tv, so I can't test the 3D aspect of the cable, but I have tested the HDMI mirroring.
I ordered the MHL adaptor from T-Mobile's website. Look under the "data" accessories for the Sensation.
http://www.t-mobile.com/shop/Addons/Accessories/Default.aspx
It was $19 plus shipping. I tried a few local T-Mo stores, but nobody had it.
Anyway, I tested it last night. You need to have a charger, a normal HDMI cable, and the adaptor. The adaptor plugs into your phone's USB port, and then you need to plug the adaptor into your phone's charger and into the HDMI cable running to the TV.
You'll get full HDMI mirroring, meaning whatever is on your phone's display is on the TV. I only tested for a few minutes, but when I first attached it, there was a portrait view of my phone's screen up on the TV. I then tested both Netflix and HBO Go, which both flipped the image to landscape, filling the TV screen. Quality was pretty good with Netflix, and only adequate with HBO Go.
Hope that helps!

Anyone tested a non-MHL micro-USB to HDMI? I don't need charging, just want to display to a non-3D set.

No such thing. Must be plugged in to charge in order for the HDMI out to work.

Show me a non-MHL micro-USB to HDMI adapter/cable.

What a crappy setup. I MUCH prefer the Evo 4G way. With this I have to carry my charger, the USB cord for the charger, a full size HDMI cable, and this adapter? LAME.
You know there's a search button right? There are about 20 threads loaded with MHL information.

[Q] How do i use MHL?

Hi guys, i bought the MHL adapter from T-Mobile's website for the Sensation 4G (i have an Evo 3D). I set everything up, plugging the MHL adapter into my phone, standard HDMI into the adapter and TV, and the usb cable into the adapter...
After plugging everything in nothing happens. I even tried playing a video and nothing occurred. How do i activate the video out? Do i just have a bad MHL adapter?
A few questions. Does the battery icon on the phone show it is charging? This means that power is going to the adapter and to the phone. If not, try changing power adapters. If the charging icon is there, then try changing HDMI cables. If this doesn't work, you might have a bad MHL to HDMI adapter.
with your tv off, plug your mhl adapter into your phone, plug your power cable into the adapter, turn your tv on and bam! (note that the hdmi doesnt display the lockscreen)

My lockscreen shows and boot animation , Also to OP ...the hdmi mirroring is not as stable as HDMWIN is for the OG Evo imo, i had to play with it a bit to first get a picture on my Sammy (unplug/replug/reboot etc.)...then i got pic without sound (OG worked w/audio), ended up running hdmi through my Yamaha amp and that worked. Still not as stable as my 4g evo....LAME
btw I've read usb can't be plugged into pc for powering, must be plugged into wall adapter

my macbook pro powers it fine. weird.
I was using it with my stand that had a video on/off button to turn the display on an off. Everything was mirrored fine but I had no audio and hulu was intentionally shutting off the hdmi before any video played. Are they blocking media streaming apps from displaying through the mhl adapter? Oh an i powered mine by pluging it into my ps3.

Funny that you ask this. I just got an MHL adapter off of Amazon that was just the adapter itself (micro USB one end, female HDMI on the other).
I connected the HDMI cable to my TV and MHL adapter, then I connected my MHL adapter to my phone. Last but not least, I connected my power adapter directly to the MHL adapter and my phone started charging.
The input should be immediate from your phone but if it doesn't, check the following:
1. Make sure your TV is on and the input is selected for the proper HDMI port. If nothing is detected, the TV should report that it's receiving no signal.
2. Make sure the power cable is plugged into your MHL adapter. From my experience, it will not push out the HDMI signal without external power.
3. From my experience, you have to connect your phone to the MHL adapter LAST. NOt sure why but if everything else checks out fine and your phone still isn't pushing out a signal, reconnect the phone to the MHL adapter. You should get an HDMI icon on your top bar.
I have the EVO3D stock.
Everything works fine for me (pictures, music, video) except Netflix. For some reason Netflix looks extremely pixellated. Not quite sure why when everything else looks fine.

help troubleshooting mhl adapter please?

Just tried watching a movie on my phone on the girlfriend's tv and got nothing... it's really annoying me now too.
-Plugged hdmi into each of the 4 ports on the tv in case was a bad port
-Tried 2 different phone chargers into a power strip AND tried extension cord from wall (nothing was open directly in the wall)
**Got nothing from those steps**
-Plugged adapter in to pc monitor with hdmi input and charger directly to wall, got picture
-Plugged hdmi into dvd player to test the tv, got picture
My first thought is the charger isn't getting a good connection to the powerstrip because the plug in front of it kinda prevents it from going in all the way - HOWEVER the phone does receive power and charged through it.
But that's why I tried an extension cord right off the wall, so not sure what it could be.
Does the TV have to be newer and support an mhl adapter? I thought you had MHL which required the TV to support AND then there was the adapter that worked with all hdmi (thus it being an adapter).

How to tell if the DNA's MHL is working?

Hello,
I'm having a problem with the MHL adapter which when connected to either of my TV HDMI ports (which worked with the bionic's micro HDMI cable) gives a white snow pattern. The HDMI cable sign starts and the audio works. I have gone through 2 PNY connectors with identical results and I doubt that the HDMI cable is the problem.

I'm running Hatka's supercharged 2.0.0. but he says he doubts anything in his ROM could cause this and others who have tried his ROM said it didn't affect their mirroring.
Do you know if there's a way I can check whether my MHL connection is working?
Thanks!
