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!
Hey guys and gals,
Although I've been lurking on these forums for a few weeks I've finally decided to join and ask some questions.
I've completed my S3 PC, got a nice monitor with HDMI input, bluetooth keyboard and mouse and of course the MHL adapter. Everything works great.. time to get rid of the ageing PC in my office.
I have a question though, I've connected the S3 to my TV and the new monitor and I never get a 1080p connection.. it's always 1080i
Is there any way to force 1080p as I do get a slight flicker with 1080i
I'm totally amazed at what the S3 can do! BTW I was a total apple fanboy until I got my S3 a few weeks ago.
Cheers in advance... and yes I searched
so nobody else is having this issue?? I was really hoping to get some help here Anyone??
Sure your monitor supports 1080p? What hz does it run when using 1080i?

It doest output 1080p via hdmi just 1080i iv tested on all my tv sets and there are all top line and display tbe same i dont get any flicker tho are you using a good hdmi cable?
Sent from my GT-I9300 using xda app-developers app
thanks for confirming snowwhite007... I honestly thought it was able to output 1080p. I guess the slight flicker is due to the monitor then.
Flickering may also be due to the phone's HDMI chip. I'm not sure if it's clock source and other components are stable enough for a clean transmission of 31'104'000 (31,1million) pixels per second (1920 width*1080 height*30 images/second / 2 (interleaved) )
1080i and 1080p have the same native resolution of 1920x1080 pixels with the only difference being that "i" (interlaced) paints odd lines before even in 2 'ticks' while "p" (progressive) paints in one go from top to bottom.
So if there is any flickering it SHOULD only be every other line, can you confirm that?
Hi, i've got a question, can anyone give me a tip which keyboard and mouse works best with the s3?
I want to do exactly what you did. I want to use my phone as a pc.
So any Idea?
I bought a cheap bluetooth keyboard an mouse from Deal Extreme worka great
Sent from my GT-I9300 using xda app-developers app
Might sound like a silly thing, but just check your power saving isn't enabled, found that while it is enabled stuff like 1080 vids played really badly. That and what type of hdmi cable you are using could be factors.
I went on hols for two weeks and just took my S3 and a portable hard drive with hdmi and usb adapters and cables and used the hotels 1080p tvs as a full desktop, ubuntu and all
I am pretty positive that everytime I have used the hdmi it has been at 1080p. My guess is maybe a tv error unless it has run 1080p before?
EDIT: Oooh, just had another thought, what exact hdmi adapter did you use? Link included if that's not against forum rules? Know when I got mine I had to wade thru a lot of close immitations that don't display properly as they are cheap fakes sold as the real thing, one would only display 720p
can you tellme the model of bluetooth keyboard and mouse? i wanna do the same

I bought a generic mini bluetooth keyboard from amazon marketplace, it's not the bees knees but its about the size of the phone, bluetooth, rechargeable and only £10.
Works great for using the terminal or typing complex passwords etc when traveling or using as a desktop.
Also used the microsoft notebook bluetooth mouse 5000, got that cheap through amazon marketplace too.
Neither come with bluetooth adapters though so would need to by one seperately if ever using with a pc that doesn't have built in bluetooth.
1080i
Hi
I recently purchased MHL adapter from this website
http://www.clove.co.uk/samsung-galaxy-s3-mhlhdmi-adaptor
And I have same problem as you. My TV only gets 1080i not 1080p.
However I don't get flickering, I just see that there is not enough vertical pixels (visible difference)
Tried bunch of different hdmi cables (cables that work with various 1080p devices with no issues whatsoever) and I always get 1080i.
Even when I try to playback video which is 1080p.
I'll try later if there is any difference if I plug it in through AMP (onkyo) and not the tv and let you know if there is any difference.
Cheers

Hi everyone,
I just got the Note 3 and am absolutely loving it so far. I also own a Samsung Smart Dock that I used with my previous phone, a Note 2.
When I dock the Note 3, it very nicely detects mouse and keyboard and sends the display to the monitor I have attached to the smartdock. The only problem is that the resolution on the monitor seems very very low and very grainy.
Any suggestions / thoughts / hints would be greatly appreciated
With your note 2 the picture was same?

I'll see about taking a pic, but initial thoughts are:
-On my monitor, I have an 1 inch area above and below the image from the Note 3.
-My monitor reports the incoming signal as being 480p
-My monitor refuses to auto adjust
To try and describe the "grainy-ness" a bit further: Any letter, for example an S (caps), that is rounded will appear with visibly pixelated curves. It is as if the resolution is very low, which would seem to correspond with my monitor reporting the signal as 480p.
What resolution does your monitor use with your Note 3?

When I output to a monitor using the MHL cable or one of the Samsung MHL to HDMI adapters it is full 1080p. 480p I can well imagine will not look too great. It's not a matter of your monitor not adjusting, if the N3 is outputting at that resolution then that is what the monitor will display. Typically the N3 will output whatever the device it's connected to will support so that implies your docking station is the problem. Either that or the input to the monitor is telling the dock that it can only support 480p but that's highly unlikely with any modern monitor.
To help you further, what is the model of the docking station and the monitor you are using and how are you connecting the dock to the monitor (HDMI, DVI, HD15, S-Video etc.)

Thanks, that's very helpful
The monitor is a Dell S2340Mc and the dock is a Samsung Multimedia dock. The monitor works great with both my PC's.
I use a 3rd party HDMI <-> DVI cable to connect the dock to the monitor. (I'm wondering if it's a cable issue?)
I have tested this in 2 configurations:
1: Dock connected to monitor via a KVM switch: Monitor reports 480p
2: Dock connected directly to monitor: Monitor reports 480p
Probably a cable or adapter issue. The hdmi-dvi is probably the weak link. Anyway for you test using HDMI straight up?

Hmm.. I suppose I could hook it all up to one of the HDMI ports on my TV and see what happens
Yes. Try and eliminate what could be causing it. If it's physical you can replace it. If it's software then you gotta figure that out.

My Smart Dock is outputting 1080p to my TV.
I have a friend who had problems outputting to his monitor, but that was because his monitor would not accept 1080p at 30Hz which is what the Smart Dock outputs video at, and it dropped the resolution due to this.
Hi people, if you ever want to hook up an HDMI 4 port KVM switch to your Samsung Smart Dock, here is a demo on how to do so:
https://www.youtube.com/watch?v=1pBSeNlMmeQ
The Multimedia Smartdock from the Note 2 has a standard output of 720p type resolutions (up to 1280x800) as this is the maximum resolution of the S3 / Note 2. The Note 3 scales output back to 720p in order to be shown on this hence why it is blurry as hell. It is very distinct difference when you compare the Dock output to a Miracast/WIDI output using a dongle - that really does 1080p (with lag) but it is so much crisper and clearer than the dock.

Both. It is roughly about half a second delay between the input/display that makes it a bit irritating. The best way to get around this is to cover the screen of the phone and just concentrate on the big monitor instead. Otherwise you will notice the difference between the two. The only machine that I know of that doesnt have this type of delay is the NVidia shield - There is a function that minimises the delay and works pretty well. Wish this was an option on the Note 3 as well.

Nintendo and nvidia have worked on stuff like this because it's a necessity for latency tolerance. It needs to trickle down already. Big reason I haven't invested in much wireless display stuff. I still live by the cable.

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?

Well the cable I have purchased is the one linked below - which the manufacturer says (elsewhere) is the HDCP compliant one. I can't guarantee you that it will work though!
I am expecting my phone and this cable this week so will try out!

NOTE - this manufacturer also sells usb-c to hdmi cables that it says are NOT compliant. Only one above is one they say is compliant.

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.

......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??) ?
