MHL output resolution - Galaxy S II Q&A, Help & Troubleshooting

Anyone happen to know if my Galaxy S2 can use MHL with a 720p screen?
My main TV reports that the signal from the MHL adapter is 1080p, but can that be changed or does the adapter auto-select a resolution? (I mean the Galaxy S2 is 480p)
I'm thinking of buying a smaller TV for my bedroom but I cant find 1080p ones (so please don't suggest me to look for 1080p one).

You can resize the screen on the tv. the MHL is up to 1080p, so it can also get lower.
I have 20" syncmaster t2000hd (16:10, 1680x1050p)
Should work good on it i guess.

HDMI Issue

Ok so I got this point of view protab 2 xxl this week, so far very nice. One issue though, when I use the mini hdmi to hdmi cable on a HD tv it works, but when I use Mini HDMI to HDMI to DVI female on a normal lcd screen without HDMI inputs nothing happens. Can this be because the resolution on the tab is to high for the LCD screen? If so is there a app I can use to lower the resolution on the tab to make it work with a std LCD VGA screen?

S3 MHL only output 1080p 24hz which makes game choppy

Anyone having issue with the original samsung galaxy s3 EPL-3FHU MHL to HDMI outputing in 1080p at 24Hz.
I currently have a 60" 1080P LCD and a 47" 1080P LCD, when connected with the MHL to HDMI, it will only output to [email protected] which play video fine,
but game or menu have that lag/choppy look to it.
I did try it on a buddy 32" 720P LCD and the MHL output it to 720p @60Hz which display game without the choppiness.
Also test it on a 24" 1080P PC Monitor and MHL output 720p to it. Is there any way to change the MHL configuration so that it will output 720p @60Hz onto my big screen 60" and 47" or even a different Adaptor that will only do 720p.
I heard you can use a samsung galaxy s2 MHL with a 5 to 11 pin adapter, anyone have this combination to test what it output at on a 1080P LCD.
If that s2 MHL with adapter works, I will return this s3 MHL and go that route.
I can only get 1080i on all my devices, all my TVs / Monitors are capable of 1080p 60hz but there was no way of making the S3 output anything except 1080i seems it's quite buggy!!!
If it just could be more improved :S No possible settings on the phone, that sucks. I really wanted to choose the resolution myself. Samsung should work on this problem.1080i sucks on my tv, 720p is 1000 times better.
EDIT: Lolz, wtf?? Just tried to connect to my PC monitor, only get 576p, my monitor is 1680x1050p. And the best thing, no way to configurate the output signal :S
We need an app, or a point in the settings. Only then we can get the max out of our superphone.
And I never hard of that thing, that someone got a galaxys2 mhl connector working with a galaxys3.
What Hz or refresh rate are you guys getting with your 1080i, I have seen a picture of someone showing a 1080p @60Hz with a galaxy s2 MHL adapter. The S2 MHL adapter by itself won't work. You will need a samsung 5 to 11 pin adapter which connect in between the s3 phone and the s2 MHL.
guys, I actually didnt know it, but I have a 11-pin mhl-hdmi-adaptor, to be exactly, this one:
http://www.amazon.de/gp/product/B0080CXSOU/ref=oh_details_o01_s00_i00
But I cant connect more devices over the micro-usb slot. I thought that it is possible with this connector, cause it supports USB OTG and MHL at the same time, so what is up with this ****?
Wikipedia said:
11-pin MHL-USB Connector
The Samsung Galaxy S III uses a connector that is similar to the original 5-pin MHL-USB connector, but it uses 11-pins in order to achieve a few functional improvements over the 5-pin design.
It supports the use of USB and MHL simultaneously (note that the new Samsung 11-pin MHL-HDMI adapter also has a USB-OTG port).
Samsung’s Galaxy S III can power the MHL-HDMI adapter. 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.

You will need this 5 pin to 11 pin adapter for your s2 MHL adapter to work with the s3, search amazon for it,
"Original Samsung HDTV Adapter TIP (5 to 11 Pin Converter) EPL-FU10BEBSTD"
Does anyone found a solution for what was the initial question?
I'm having the same issue also using the original samsung galaxy s3 EPL-3FHU except that the display is limited to 30 Hz for me.
Maybe it will be fixed in jellybean.. doubt it very much though.
I am having the same issues ... I have a Vizio 1080p 240hz and I am getting choppy gameplay too. Very disappointing, considering that gaming was the sole reason I bought it =(
I wish Samsung with come up with a solution.
Does anyone know if you can buy these any cheaper than £25 ($50)?

720p only
I have a whole different story going on...
With this aftermarket hdmi mhl adapter i only get 720p on tv, sound out of sync, flickering, display cutting in and out.
With same movie on droid charge via direct hdmi get 1080i on tv, perfect sync, all apps work flawless as usual.
This aftermarket adapter cant be that bad...?!
Any input?

And..............only ma466 in the chargue electric not the ma999?, not sufficient foir chargue the battery the galaxy via MHL HDMI...
Is a joke?????

no one more news or gadgets since?
I also have choppy output with my S3 MHL adaptor. I wonder if there's a way to force the refresh rate somehow?
Has anyone tried overclocking to boost the frame rate? I've had the same problem as everyone else when trying to watch 1080 video on a 46" 1080 TV, but it only skips once every second or two on random intervals. It's JUST enough skipping that you know something isn't right, but almost can't put your finger on it. I may try overclocking to boost it in the next few days. If I do I'll post back with results. For reference, I'm using an ATT GS3 rooted with the stock TW ROM.
I just get 1080I on my 1080P sony Led 55" and 1080I on my Dell 1080P monitor 24"
I rather get 720P than 1080I, but i cannot change it
Better but still an issue.
I just installed the Hyperdrive rom with the kernel that can overclock on my SCH-I535 S3 and tried the official 11 pin Samsung hdmi adapter and was getting 1080 at 30hz witch is better then before. Also my phone was syncing to 30hz. Before it was 1080 at 24hz and the phone was syncing to 60hz witch caused every thing to look extremely choppy. Now games are playable but still could be much better if we had 720 at 60hz.
I'm not sure what changed from the stock rom to Hyperdrive but it seems that the output can be changed some how.
Also I seen that the HTC One S has a kernel (ZeroMHL) that can force there hdmi output to 720 but I don't know if the same method could be applied here.
Edit:
It seems that ZeroMHL fixed the kernel by finding key words and changing the limitations. As a professional I'm a video game programmer but I'm going to try and see if I can modify kernel source to get 720 60hz. If I can do it ill post the kernel / source.

[Q] SG3 MHL to HDMI: Only 1080p with Samsung TV's?!?

I just purchased the official Samsung Galaxy S3 11-pin MHL to HDTV adapter from Samsung.com as a replacement for the Allshare cast dongle, because the Allshare dongle only supports 720p output.
However, when I hooked the wired MHL dongle up to my GS3 and Vizio VW42L LCD TV, it was still outputting at 720p.
So, I called Samsung mobile support and bounced around from department to department for an hour. During the call, I was told:
-It's my TV that isn't compatible. (Although my Xbox360 and cable box both output at 1080p)
-It will only display 1080p when playing back 1080p media. (I test-recorded a 1920x1080 video on the phone and playback was still at 720p)
And finally, when my request was "escalated" to their higher support level:
-The GS3 will only output 1080p video to Samsung TVs.
Um...WTF? Is that the truth?
Samsung's own site says both "HDTV Universal Adapter" and "1080p" in the specs for the 11-pin dongle. Go to Samsung's support page and search for part number EPL-3FHUBEGSTA to see for yourself.
Has anyone else been able to output 1080p video with the OEM 11-pin dongle to a non-Samsung TV?
If the "compatibility" issue for non-Samsung TVs is accurate, doesn't their page for the S3 11-pin dongle constitute false (or at the very least, misleading) advertising?
Uhm. Isn't the Vizio VW42L a 720p tv? IIRC, its resolution is 1366x768.

Nope. Like I said, I have other HDMI inputs (Xbox 360, HD cable box, and a desktop computer set at 1920x1080 resolution) that all display correctly at 1080p.
I get 1080I on my 55" sony lcd and my 24" dell monitor, but no 1080P I rather have 720P than 1080I, but i cannot change it :crying:

note 2 to hdtv through MHL only going to 1080i

when ever i try and output my note 2 to my tv via the MHL adapter, it only ever goes 1080i, never 1080p. Is there a way i can force it to go 1080p?

What are you trying to play? Remember that the 1080 interlace and 1080 progressive have a lot to do with the connection, cable speed, and the actual format of the video rendering. Make sure whatever you are trying to play first of all is actually 1080P.
I also got this problem any solution?

[Q] MHL 1080p output

Another MHL question from me.
Does the XZU support 1080p output over MHL? I have a feeling before the KitKat update that it did. With KitKat update, when I plug in the MHL to my monitor, the monitor reports a 720p signal. There was another post where someone stated you can change the resolution settings but I don't seem to have that.
I use mine with mhl latest kk build and it's 1080p I don't know where you can change the resolution. The only thing that bothers me is that the mhl 1 standard that the zu uses only supports 30hz

Thanks for the info. I tried two MHL adapters on two different monitors and both report 720p though I know these monitors will support 1080p through HDMI as I get that resolution when plugging in a monitor. Maybe something weird with the HDCP handshake? I'll try on my HDTV when I get home. Hopefully I don't have to go questing for a different MHL adapter (had to go through three to find one that would charge my phone while using HDMI out).
I have one that it charges my phone directly from the TV but the TV has one hdmi with mhl built in. If you use one that you needs 5v from charger or USB you should try the I9100(S3) mhl dongle works perfectly with our zu

Yes, same thing happens to me as well.
I bought this: http://www.ebay.com/itm/321336887491 and the output is 720p 60hz.
The image is blurry and it is very annoying
If I remember correctly same thing has happened both in 4.3 and in 4.4 (rooted locked bootloader)
Hi harisled, I haven't tried it on my HT setup yet but I think I know why it is not working (at least for me) on my computer monitors. I had forgotten that the MHL 1.0 spec only allows 1080p @ 30Hz until mr.joshuanice had mentioned it. The two monitors I tried it on initially are computer monitors so they probably don't support 1080p @ 30Hz. I'm guessing the HDCP handshake (or whatever it is called) reduced the resolution to 720p @ 60Hz which is supported by my monitor. However, this causes the monitor to upscale causing the image to be blurry (like you have experienced).
I will test it on my HT this weekend which should work (I remembered testing this out a while ago). The only thing that sucks is playing games @ 1080p. As some have experienced, playing PS Mobile games at 1080p resolution makes the game really sluggish (@ 720p is great). I remembered someone had show a screenshot of a menu which allowed you to change the resolution but it may have been a different Sony phone or a different ROM.
You are right, it did output 1080p 30hz on a tv

You can enforce the output format by dialing *#*#7378423#*#* then navigate to Service tests -> TV-Out Test -> Video format. Note that "Video format" will only be modifiable when the MHL cable is plugged in.

I tried that on my PC monitor but, as expected, nothing changed since the monitor does not support 1080p 30hz

when i connect my zu to tv phone appear mhl connected but tv is black screen when open service menu
mhl is on
video fourmat N/A
HPD 1
TMDS off
what shall i do ???
please!!!!
I know this is old, but is there an option to save the MHL-Setting in the Service menu permanently? After each reboot, the screen resolution is scaled to the default settings again.
Everybody who has problems with screen resolution can simply set the resolution and fps in the service menu under "second screen" .. For that type *#*#7378423#*#* in the phone dialer
For me its not even switching to 1080p when I select it in the service menu. It says reconnect but then again its set to 720p. Xperia Z and Z2 only outputing 720p. Are they even capable of 1080p MHL?
Is it possible the MHL cable is just crap?

The Z Ultra has MHL 1.0 or most likely 2.0 since 2.0 requires 900mA and therefore an external power source is needed (which my cable has) while 1.0 only requires 500mA, which is provided through a regular USB/HDMI. Both 1.0 and 2.0 support uncompressed 1080p and Dolby 7.1. MHL 3.0 was released just a month before the Ultra hit the market, so it doesn't have 3.0, which supports 4K and some other stuff.
The Z2 and beyond have MHL 3.0, and yes, it could be your cable. Be sure that it's 3.0 for the Z2 and 1.0/2.0 for the Z.
I tried 2 MHL1.0 adapters before and the output was 720p only for my Sony Tablet Z4...
Luckily I found the MHL3.0 adapter last night and the the output become 1080P 60Hz for my projector now. Try to find the MHL 3.0 from Taobao or eBay.
