Hi Guys,
sorry for another thread about MHL, but I think this should be visible. I got MHL adapter directly from Samsung (borrowed for testing) and here are some troubles:
1) TV is showing that source is 1080p, but real picture is not that good. Maybe it is worse than 720p.
2) You cannot use the original Samsung MHL without charger in it. Simply the screen shows "no signal".
3) Bigger problem is the fact, that SGS II is discharging while on MHL, even the system is showing charging indicator. It is really weird and I will try to contact Samsung for some details.
Before I will send that email, can anyone check it? In my test it is enough to run some 1080p trailer at highest brightness for about minute or two. After that you will loose 1% from capacity.

What ROM you running?
On earlier ROMs, whilst playing Order & Chaos on charge, my phone would still lose battery.
My setup:
Android version: 2.3.3
Baseband version I9100BUKE1
Build number:GINGERBREAD.BUKE5
According to Kies, this is the latest version available.
interesting, what are you powering it with?, psu adapter into a plug socket or are you just using a usb port to power it, if you are using a USB port to power it then it may not be pumping enough amps.
In regard to the poor picture, The MHL is just HDMI digital and so it cannot effect the picture really, I suspect your player on the phone is doing something to it, alternatively does your TV have compression on that input channel to soften or deblock? - are you sure the video you are playing is full HD or just looks like full HD on your small sg2 screen?
Its a bit worrying if it still drains as this effectively defeats the object of it.
I'm using original charger, which is in the pack. I'm going to test it on second Galaxy S II today and see the result.
With the resolution - I've made the tests on Philips Cinema 21:9 (2560x1080) and even the menu is really awful. Photos taken by the SGS II are slightly blur and text in browser hard to read . The trailers are also bad, as I said above.
I used PC with that TV and same trailer is absolutely smooth, so problem maybe in the player on SGSII, but I bet on problem somewhere in MHL transfer.

I don't think it matters what charger you use, I have just found out the battery is capped at 0.650amp in the kernel....

The 650 mA limit is in effect when it's connected to an AC charger, as determined by the resistance across the two data pins on the microUSB connector. Low resistance (< 200 ohm) indicates an AC charger; if the resistance is higher, it will treat the connection as a standard USB, in which case the current is limited to 450 mA (just below the 500 mA minimum +5VDC current in the USB 2.0 spec). Speculation is that the 650 mA limit is in place to keep the battery from overheating/exploding during charging.
What's almost certainly happening is that the SGS2's charge logic considers the MHL adapter connection to be a regular USB connection, thus limiting the charge current to 450 mA. If the SGS2 is drawing more than 450 mA as a result of its exertions (such as playing HD video), the battery will discharge.
There's probably a reason why Samsung did it this way -- the AC charger also has to power the MHL adapter, which has a bridge chip & support logic on it. If the SGS2 tried to draw a full 650 mA from it, the charger might not have enough capacity left to power the MHL logic.
The power issue has been covered now so it just leaves the output quality. So what you are saying is that you have played the same trailor on the TV using both a PC and your Phone and the phone output is bad?.
Any chance you could take some photos so we can see, I ask as HDMI is digital, you don't really get interference like old scart or S video adapters, usually the picture is either there and sharp or not there at all. If it is blurred it is either the player applying some sort of de-blocking / compression or the TV is, just cannot see this being the adapter.
The SGSII outputs in 1080i. Set your TV to 1080i instead of forcing it to 1080p and the image quality should improve. On mine, menus look crisp and games all work fine. The TV shows that it is 1080i, and I have set mine to accept all settings (720i, 720p, 1080i, 1080p)

So basically when I enable HDMI out to my 2560x1440 screen (u2711), the motorola logo displays just fine, but when I select a mode like gallery or mirror, the whole HDMI screen starts flickering and showing portions of the screen every couple of seconds.
The phone itself works just fine, and HDMI out with the same cable works fine on my HD ready TV. The HDMI port on my u2711 is fine as well, at least it works with my xbox 360 in 1080P without error.
The odd thing is, as soon as I enable Picture by Picture on my screen, the phone displays just fine on it's half of the screen, albeit in 640x480.
Is this a known bug, or does anyone have any suggestions on fixing it? Do I have to disable DDC/CI? My cable has ethernet capabilities, so the high res shouldn't be the problem, right? Or did I just buy a ****ty/faulty cable.
I don't think the phone is capable of rendering at a resolution that high, the gallery is in 3D-mode and it's probably running out of Vram..
Maybe force it to 1080p somehow?
I never got the HDMI cable working from my pc high end gfx card to my dell u3011 . Never tried from my Razr but I guess the same applies to it.
Only dual DVI and DisplayPort worked.
Without checking I think the highest res possible on hdmi is 1200p ?
I would always try a different cable before giving up. 9/10 times when I have seen flickering on an HD display it has been a crap/faulty cable, and I have seen it a lot as until recently I was Digital TV installer. Used to carry loads of spare cables in the van as it used to happen so often. You don't have to spend loads on a cable but the very cheapest are usually best steered clear of unless you're lucky. I'd usually go for a £10-£15 cable (15-20 EUR) and not a cheap ebay one.
Thanks for your advice guys!
The max res for 1.4 is 4096×2160, and for 1.3 it's 2560x1600, so my resolution should be fine I think.
I paid ~20 euros for the cable, it's brandless, but from a well known cable retailer here. I don't have any others to test, and compatibility with my u2711 isn't vital to me, so I'm not going to buy another cable, but I still think it's odd that it doesn't work.
I will report back if I find another cable and it makes a difference!
Well.. I just received my Kidigi MHL cradle with excitement
Two things... it pees me off I cannot use the cradle WITH a case on, like the other Kidigi cradles (ARG!!!! - The pic showed a phone with a case on in the cradle!), and then I discover that the AC Adaptor is defective (loud buzzing when there is no current draw.)
I'll try the HDMI in a bit if I can.
OK, what am I doing wrong here... plugged in, HDMI cable plugged in.. but screen not showing up.
Do I need to activate any special application or something?

My Samsung tv didn't like the evo 3D's HDMI (worked fine with my 4G). I ended up routing the phone to my yamaha amp's hdmi then to my tv. Maybe try another tv or device.
It's got a built-in MHL adapter? So you can plug an HDMI cable right into it?

Yes, apparently so. http://www.kidigi.com/product_lv2.php?pid=1316
Typically doesn't say 'mhl' in kidigi's page though.. but did on ebay.
I have ordered another HDMI cable (v1.4a) just to be sure... but as the ac adaptor is making an audible buzzing, I'm seriously likely to send it back anyway.
I was previously using an HDMI to DVI cable with this, and it didn't work at all. So I ordered a V1.4a HDMI cable instead.
It is most odd, because it seems to work intermittantly. The monitor keeps blacking out for a few seconds, and then working fine for about 20 to 30 seconds.. then blacks out for a few.. then works for 20 to 30 secs....
Not sure what to make of that really. Maybe the auto-rotation is messing it up a bit.. will have a fiddle with the settings.
And now it seems to be working just fine. I had made sure cables were pushed in... maybe the rear wasn't in enough.
Apart from that, I had changed from 'charge only' to 'HTC Sync' (whatever that is), and the phone is now fully charged in the cradle.

How does it look on your TV? What size is your TV? I bought two MHL adapters and NEITHER work on my 61 inch Samsung DLP, but they work on my mom's 19 inch HDTV. However in some areas the picture seems to have a faint checkerboard pattern, especially when scrolling through the gallery. You notice this effect at all?

I will have another look tonight. I'm viewing it on my 26" monitor. Image looks a little grainy I remember, but that's due to it being on about 720p rather than 1080p I believe.
The auto-rotation is a bit screwed up when it comes to 'dock mode' though. You enter docked mode, it displays in portrait, but then when the weather gets displayed it only shows the weather animation and goes into portrait mode (even though the phone is still in landscape), so pushes things off screen. I have no idea why it does this.
My O2X HDMI output is flawless. TBH considering the amount of *****ing the O2X got (even by owners), it's a phone that works very very well.
If I can get the 'issues' sorted out I'll look to get an android bluetooth keyboard and mouse
I have the same dock and the problem is it only charges with 500mA. I made a Tasker profile for a Desk Clock and when the screen is on, the net current is like +2~20 mA (practically zero) So I did the charger mod (soldering together the data pins) on the AC adapter and now the AC adapter itself can charge the phone with 1000mA but the dock itself presents itself as USB and falls back to 500mA. I will either try hacking the data pins on the dock or patch the kernel to allow for fast charging. I have to look into it more though, MHL portion might stop working with data pins crossed.

For a dock that I might have the phone in for a while, i would prefer it slow charging anyway. Means device should be cooler.
I do not have a cradle but my MHL adapter does suck battery and a dirty hack to maintain battery would be great.
I got my MHL-HDMI cable from Amazon for $10, it's the one listed in the ultimate accessories thread in this forum. It is not working well for me at all, lots of flickering and going blank.
As I understand it, MHL should mean that the phone should be in USB Data/charging mode so it can pass data to the MHL adapter, am I right in assuming this???
If so then the problem may be that the adapter isn't communicating properly with the phone and it's bouncing back and forward between AC Charge and USB mode which would cause all kinds of problems.
Can anyone with a solid, non-flickering MHL adapter check their battery status in 'About Phone>Status>Battery Status' and tell me if it reads AC or USB mode for charging when they are mirroring over MHL HDMI??
Mine reads 'AC charging' and plugging it in I get horrible screen and audio flicker and the screen resolution seems very low. I have the AC power plugged into the MHL adapter and I plug that into the TV first THEN plug it into the phone.
It's pretty much unusable like this, seems like a lot of people are having the same issue with many Samsung phones and tablets.
Anyone resolved this on their note????
Joel
Did a little more testing and noticed something that I think may be odd, wondering if others can confirm.
I checked my battery charge status while plugged into the MHL adaptor and watching the picture flicker on and off on my TV. It read that I was charging in "AC mode". If the phone is in AC mode then surely the data connection to the MHL adapter wouldn't be working and the phone may be pulling too much power away from the adapter for it to work right??
Just wondering if you figured this out. I got the mhl adapter yesterday but the screen flicker makes it unusable.
Figured out that the flicker only happens when wifi is on. When I switch it off its smooth.
Is this the same for you?

I have the ATT Version of the Phone ... and it didndt come with the MHL Adaptor
http://www.google.com/products/cata...=X&ei=zczLT8GLCIOG6QHJhpjtDw&ved=0CJABEPMCMAA
The one I am using is from my older Samsung Infuse - ATT phone also!
I had that working BEFORE with Infuse , and works just as nicely with NOTE
I have the cheapest HDMI v1.4 cable - nothing fancy ( pack of 3 = $5.00 - free ship) ....
The only thing I am P*** about is the in INFUSE - all video's you can load ( 1080p) in mp4 ( borrowed from Itunes etc) with DIRECT TRANSFER ie the infuse didnt go thru any 'conversion' before addin to phone.
In NOTE - the same file - note wants to convert to 'mv' - and in my view = this making it NON 1080p format. Since my NOTE is rooted& unlocked , i can and able to by-pass that conversion C***..
.NOTE = does go into "charge mode' when you stop playing videos/ movies ( I have 64GB sd card ( formated for 32 apps +etc and other 32 GB for movies /videos
Ausmike or anyone else: does your note only charge when using this adapter and not streaming video? mine eats up battery when playing video and streaming and it pisses me off. Why couldn't samsung just used a simple mini HDMI or something similar
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.

Maybe it will be fixed in jellybean.. doubt it very much though.

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.
Hi. Has anyone tried using a USB C-to-HDMI cable to connect Mate 10 to a monitor. How do you like it? Do apps scale well on monitor? Assuming you hooked up a bluetooth keyboard and mouse, have you tried editing a document? Thanks!
still waiting for my Mate 10! But one of the reasons for getting one is USB-C to HDMI. One thing I noted when sourcing a cable - if you use a "standard" cable you won't be able to stream Netflix/Amazon streaming due to lack of "HDCP" compliance. I got a cable that was compliant for a few euro more on Amazon. Just keep this in mind if you want to stream Netflix etc.
Does anyone know if this would work with a Surface Pro 4? The SP4 has a mini display port, so maybe with a mini display port adapter, we can connect Mate 10 to the SP4 and view desktop mode on the tablet. Would that work?

Thanks I'll look for it here in Amazon US, no problem returning so might as well try.
I tried it out briefly when I got the phone.
I used a type c to HDMI adapter, with a normal HDMI cable.
Some things I noticed:
I think this drained the battery more than anything else I've done with the phone (including gaming).
The phone was noticeable warm after the session.
My phone rebooted shortly after the desktop session. Like it crashed.
The phone states it's in reverse charge mode, like juice is also bring drained from the phone to the TV.
I couldn't get YouTube to work full screen without borders. Unless I was mirroring the phone screen (which means phone screen also remains on).
I've mixed feelings, it's early days I guess.
Ok, I am still waiting for the cable from Amazon but ended up purchasing an adaptor from Maplin.
Worked fine - as in outputted screen of phone (in phone or 'desktop' mode).
But I did notice that the screen resolution as outputted was far less than the resolution of the screen - I would have expected the 1080p display to mirror across to the TV.
It wasn't that it was bad, just blurry text and not crisp when looking at video. Whereas in the past, with a phone with an actual hdmi connection as opposed to usb-c, or indeed when outputting a media player with hdmi or casting using chromecast, the quality is perfect.
Perhaps I'm doing something wrong or perhaps the Maplin cable is not up to speed. Open to ideas.

No, normal Mate 10.
Other cable arrived and same situation. To clarify, it's fine, and perfectly watchable, just not crystal clear. It strikes me that this method seems like the usb-c to hdmi cable is simply mirroring the display of the phone rather than actually outputting the video file itself independently - as would happen with a HDMI connection as you used to get on some phones. Perhaps this is something to do with the issue.

Other cable arrived and same situation. To clarify, it's fine, and perfectly watchable, just not crystal clear. It strikes me that this method seems like the usb-c to hdmi cable is simply mirroring the display of the phone rather than actually outputting the video file itself independently - as would happen with a HDMI connection as you used to get on some phones. Perhaps this is something to do with the issue.

......hope you post result of amazon cable! have a nice day!
It was amazon cable I referred to above. So same with maplin adaptor and amazon cable. Tried outputting a HD YouTube video but not much different. As I say, fine, but not as clear as would expect if you copied that file to a media player attached to a tv via hdmi
Hooked mine up with the Huawei supercharger and cable and it slowly drains the battery in desktop mode. Without charger it will suck down the battery fast. Benched with Antutu and got 175k on phone. In desktop on 30" monitor got 157k. Still faster than my Mate 9. My S8+ in Dex was just about worthless. Also with the M10 in desktop with wired mouse has zero lag. Bluetooth mouse a different story. So gaming is pretty good on a monitor.
Ok, I "solved" my problem by fluke. I would love if someone more techy than me could explain but this is what I did to fix the fact that the HDMI output looked more like 640x480 than a hi def picture.
Went to TV settings, and selected advanced, HDMI settings, and Changed HDMI "Auto" mode to HDMI Graphic mode (choice of Graphic/Video - video was default and was crap). As soon as I did this I had perfect outputted photos and videos.
According to one tv manual I found on a search:
"Graphic: HDMI input timing set to Graphic mode (PC) - The image is full scan.
Video: HDMI input timing set to Video mode. The image is over scan."
According to someone on a completely unrelated PS4 forum:
"Basically by changing the HDMI mode to graphic, the HDMI output (be it gaming console, pc, or cable) bypasses "extra" processing features of the TV that
make the game and TV broadcasts look crappy and also causes lag. By bypassing those features you will get a much clearer picture."
Either way, it's fixed. On my tv. And on a shop tv the same issue. So given that I've connected previous phones with hdmi connections a few years ago without issues, this suggests that it is something to do with how the Mate 10 outputs signals in a way that TV recognises?
Love to hear an explanation from the experts. Thanks.
Edit: someone else with a similar issue on another device - so it seems the issue is that the Mate 10 is not recognised by most Televisions as a "PC" which would correct hdmi mode to "graphics" ?
"When I switch between the Blu-Ray and the PC on two separate HDMI inputs, the TV doesn't detect that's it's connected to a PC, so it doesn't switch from video to graphics mode - which is required for it to look good as a computer monitor.
Since the TV deosn't recognize the PC and auto switch to graphics mode, when I switch from Blu-Ray to PC, I have to dig down into the menu and switch the HDMI mode to graphics manually - and then back when I go to the Blu-Ray. -- Major pain if I'm switching back and forth."
Any ideas? Is this something Huawei could fix in firmware?

It looks like its related to the TV resolution : I have the same issue (640*480 resolution) when I connect the mate 10 pro to a 4K native TV but it works perfect when connected to a full HD TV !! It's a shame as 4K tend to be the standard display, so I guess Huawei should fix it whith a firmware update. Any other solution (HDMI 2.0 cable maybe??) ?
