MHL, delays and input lag. - Galaxy S III Q&A, Help & Troubleshooting

Hi all
Running foxhound 1.3, using galaxsih kernel, just popped my MHL cable in my TV.
Anyway needless to say its very cool. However its got a slight delay in input, making gaming a pain in the ass.
I'm using an official MHL cable, powering it with an official power pack and my tv is a beast, all post processing on the TV has been disabled and game mode has been activated, meaning that it should run as good as it can.
I think I've done as much as I can to bring the delay down to a minimum, but its still very noticeable , gaming is not very good because there is a noticeable delay, so anything that requires quick reactions is a no no.
Does anyone have any input about this? It would be superb to get this working well, its cost a few quid to buy all high grade components to set this up, its a shame that its fell at the last hurdle.
Any help would be great
Thanks.

Know that feel, bro.
I also bought the official samsung mhl adapter for s3 (int. edition). And guess what, this adapter gives out a signal of 1080p30Hertz
For real, wtf, is this, only 15 frames per second, videos are not really watchable, games not enjoyable, extreme lag on games, something that shouldnt be, but it is there.
I asked sammy bout that, they said I should send my phone to the service center cause it could be broken (hahaha -.-'') Or my adapter is maybe a faulty unit. I dont know. I have to test it with other s3s. Maybe the adapter doesnt work properly cause my phone is flashed (with system marked as changed and not official state, so I cant update via OTA).
I have to take some time this weekend to check it out, cause it would be really awesome, to play on my FHD tv nfs most wanted.

Dont be sending it back just yet, i've got several s3's in work and i'll be trying them out today, i've attempted it on my two tv's (both Tv's switched to game mode for fastest response time) A Panasonic viera 3DTV, and an LG 3DTV, both top of the line. My HD cables are gold plated high grade 2 metre cables, the MHL is also Official.
I don't believe it's the handset at all.
I think it's just a crap job done at mirroring.
I honestly don't want 1080p, i just wanted 720p, i wanted it to mirror whats on the handset pixel for pixel.
It doesn't need to render it twice, just mirror the one set ffs.
Samsung are terrible for this, there is about half a second lag on my TV, playing tekken was sh** and lagged, on the s3 it was rapid.

Does anyone else have any input on this?
Tried i don't know how many TV's and all have similar results.
Surely it can compete with the like of apple when it comes to getting your device on TV

Are you try using another Rom? just to test it is the MHL or the Rom?

I've tried it with omega and its the same. I also tested with different TVs, 5 in total and different cables too. 3 in total. And two different HDMI cables.
Maybe its just bad luck. I'll attempt it with another ROM.
Have you used the MHL cable yourself? What results did you have ? I'm aiming at gaming more than anything.
Cheers.

I've just received a MHL adapter, it's not the Samsung official one though.
I don't have any noticeable input lag but I can see it's always running at 30fps.
That's easy to notice while playing emulators (Sonic on megadrive/genesis ).
I tested it on my Samsung 1080p TV, it gives a 1080p output at 30Hz which I think is the maximum possible with this MHL technology atm.
So, I thought "let's try this on the 720p TV I've got downstairs, maybe it will run at 60FPS".
And... no, still 30FPS at 720p.
I was wondering if it was a cheap MHL fault and if the Samsung official one would run faster, what do you guys think? you always have 30fps as well?

Not sure what mine runs at, all I know is that it cost £27 and its nowhere near as good as the iphone one, which pisses me off as I can't stand it when apple has something over android.
That aside, I think the s3 and this mhl technology should work well, but as far as I can see, besides simple browsing and movies, gaming isn't all that good. Infact unless your playing solitaire or pool or something, its not possible. Was playing real racing and although it looks amazing, the delay is just so noticable.
Tekken 3 on epsxe was unplayable and it lagged.
Haven't tried it since the 4.1.2 update but I can't see it moving ahead a lot. Will test it again and see how I go.

I'm stuck at 1080p at 30hz, don't have the option to alter it on my TV, would be nice to be able to have 720 with 60hz.

Thanks for the answer.
Everyone seem to have this problem, 30Hz max while it's technically possible to do [email protected]
I saw someone made a modification at kernel level on the HTC One S to force 60Hz. I asked him how he did but didn't get any answer yet.

Would be good to know how as the delay and lag is a killer.
Great for movies crap for games.

I found his github with the commit but the files are not similar to what we have on I9300.

I've now found that my 0anason8c Vieira runs the mhl cable at 1080i at 60hz. It is smoother. But still not perfect.

Hello
Got a Galaxy note 2, stock ROM JB 4.1.2, with samsung official GS3/GN2 11pin adapter. I have the same problem with the official smartdock and the Juice Defender 5 in 1 MHL Connection Kit.
I have the same problem described by the OP: Output seems to be 1080p.
But about an half second lag that just make games impossible to play on a TV. And that is also easy to see when I open app on the home screen.
Do you really confirm you have no delay ?
If yes I would be really interested in having the ref of your adapter.
30fps or 720p would be just fine for me if I at least I got no delay.
Note: And in addition, I can see with emulators such as N64oid the rendering is much better on my phone screen than on my TV (that's blured and pixelated), what is not the case in other apps (homescreen, video player, ...).
UPDATE 06/05/2017:
The delay was caused by a setting on my TV.
I noticed the same delay when I connected the TV to my PC. After having enabled the PC mode on the TV, the delay disappeared.
I have not rechecked with the phone and the MHL adapter, but I am now pretty sure the delay should be solved now.
Sorry for this false alarm.

Hi, I checked my cable and where I bought it but it's hard to answer.
There is just "HDTV adapter" written on it and no reference at all.
The shop I bought it from has a different adapter on the picture now, so I think they send whatever they have atm.
The price is higher too...
Sorry can't really help here.
I also suspect different TV can have more or less input lag with an MHL connected (and they already have different input lag natively btw).
Bad technology...

Thanks for your answer anyway.
In fact that cannot come from the TV, since my TV (like almost all) is not MHL enabled, meaning there are only regular MHL inputs.
Of course there is a small delay on all TVs, but there is a really big difference between the phone and the PC, if I connect it on the same HDMI input.
So the delay could only come from the MHL to HDMI bridge or to the phone itself.

stock kernel may help fix the mhl delay.i use stock rom with kernel and stock launcher. i do not have mhl issues. also nova launcher may cause mhl to not work

OK, but actually I use a GN2 stock ROM JB 4.1.2. Are you in JB 4.2 ? Or maybe there is difference between S3 and GN2...

[Q] Micro-USB to HDMI?

This is a question, that is very important for me.
...
You see, this SGSII phone thing'y is HOT as HELL. It is everything I want in a phone... BUT STOP...
...
NO HDMI out?
...
The original SGS has one and I really don't understand why they took that away from the SGSII.
...
I heard that there is a way to get HDMI mirroring with a software and a micro-USB to HDMI cable! Is that purely a software question or must there be a hardware thing to?
...
Please... respond to this, this is very important.
An MHL hardware connection is needed (look up MHL in wikipedia), fortunately in the official Samsung specs from the press release it says that it has MHL. A video from MWC from someone representing the MHL consortium also says the SGS2 will be the first device supporting MHL.
I'll feel better once I see someone demo it, but Samsung have officially announced MHL capability for the SGS2.

Yes... I want to see a demo to. It would be nice to have this mirroring capability.
Something does confuse me about MHL, if you have a TV which isn't MHL compatible and you don't want or don't have the adapter, can you use a microUSB-to-HDMI cable and just not have it charge at the same time?

My friend you can use with any HDTV but you dont have charge of your battery device except if you buy an adapter MHL to charge and transmit signal on the same time. But how last your battery can provide of energy?
In my Xperience In my IPad I see 3 Movies via Wireless Apple TV and my battery show 30 % remain. In the case of SGSII at least You have enough power to see a movie with Screen turned Off (SGSII)
!?
Are there any news about a mirroring capability on the SGS II?
...
I've been searching the net for some confirmation, that there is going to be a possibility playing games on the SGS II connected to a flat screen TV, but couldn't find anything to confirm that!
...
Are there any news???
surely if this was possible, it would have been all over the exhibitions and videos of it would exist?

Or the SW used for demo phones didn't have the mirroring properly implemented yet and the option was not included in menus.
EDIT:
I have not seen any demos where SGS2 is connected to a TV via MHL/HDMI.
Is there any previews or videos where they use that ?
No videos yet, the question of whether mirroring is on offer remans in the air.
!
Funny... cuz... The first SGS had mirroring, if this one has it not, than it is a kind a regress!
...
Sorry 4 my English.
Yep, I'd be very disappointed if this can't do mirroring, I love using it with my SGSI and would find it hard to part with (use my SGSI on the tele with BT keyboard and mouse, excellent experience, only problem is only SD-out).

[Q] Tv-output on Ace

hi
is anybady had tried that Tv-output working on Ace
There should be a way..
Thanks for bringing this up, well, I thought about it, and contacted Samsung regarding that, and the short answer for this was NO, Ace does not do tv-out
Now, we know that the 3.5mm audio jack has 4 contacts used for ground, mic (in), left channel (out), , right channel (out), I thought there should be a way to use one of the channels to send 'video' information rather than audio, the problem is, these are used for audio and we need to modulate audio frequencies to carry video signals via a software (app).
For ordinary NTSC video the bandwidth is about 4 MHz. So we'd need a higher frequency carrier than that to convey it, so it's very difficult, sending anything close to full-motion video through the phone's audio connection is not possible (theoretically). The audio bandwidth is not sufficient to carry such a signal.
But there's hope (i think), afaik, "radiofacsimile", and "slow scan TV", send video info via audio channels, the thing is they are so slow, i.e. with low frame rate (really low) this should be technically possible, and this is enough for some applications like displaying still pictures or slides on a large screen.
What I'm suggesting here, if there is a good developer who can develop a simple Android (or whatever) app that takes a snapshot of the screen, creates a corresponding video signal, convert it to wave, then send it via one of the audio channels on the phone, and using an 3.5mm-to-RCA cable (like the one used for Nokia handsets) the audio can be used to deliver the message to the TV or sth, there is another option which is to use the micro-USB port which can handle better signals, but that's digital, but again, there is a micro-USB-to-HDMI cables, and we can use one of them, and here we can send audio and video, so software can solve this, I can start building this kind of app but I'm not that good with mobile development, so if anyone is interested, lets do it! this would not be for Ace only but for many other gadgets..
I also heard that there's a custom ROM that can use the audio port for similar purpose, not sure if that's really possible, or if it's really true, Galaxy S can do that btw.
just a thought can it be done through usb?... i mean there are tv's and players which supports usb inputs like sdcards, pendrives.. but i guess this thing would be limited to playing videos on our sd cards.. (like we play the music through aux in ports).. and not the total output of our phone's display...
can anyone test the normal video playing through usb cable... i don't have a tv or player with usb support..
Hey guys jus found thid video on one on the website...d guy was able to have an tv output on ace here is the video
http://www.youtube.com/watch?v=8c7PG7AL4Jw
But he had sum problem and he has given this message
Hi,
I just got success in sending my screen to LCD via USB.
There is a lag between devices because its usb not HDMI
cable, I think if I use an HDMI usb cable than there will be no lag.
Sorry guys this app made by me is deleted because it
posed a risk of burning gpu and very laggy.
So I cannot release it.

[Q] MHL and Emulators

Okay so I've seen plenty of videos on YouTube of the SGS2 playing N64 flawlessly on their bigscreen TVs with PhoneJoy and an MHL adapter, so I figured our EVO 3Ds should be able to handle it too... but so far that hasn't been the case for me.
Has anyone come up with a working configuration to get emulation to work without like 10frameskips?! I've tried multiple ROMs, kernels, overclocking, all sorts of different emulators... I can't even get simple SNES games to work well enough to be standable let alone N64. Tried all of yongzhs emulators but those are too outdated and don't work smoothly. Best experience I've had was with SuperGNES because its not a port it is android native, still have to give it about 4frameskips though which is much too choppy. Looking to get about 1-2 max. Any thoughts and ideas are most appreciated!
If u don't mind could u tell me what kind of games u want to emulate like n64 or perhaps gameboy games
But Well u can try gameboid for that games. it works pretty fine for me O(∩_∩)O

I dont know if it a Sense related problem or something, but any 1080p video lthat I play using MHL on a big screen is to much choppy and fps are too low....while the same videos works fine without MHL.
I really hope all this is resolved when ICS and sense 3.6 or 4.0 OTAs are released...

thats because most mhl adapters can only push 24hz making it look choppy. cannot say if the oem htc or samsung adapters are any better however i have heard that both image, sound and framerate are better.

I use samsungs MHL adapter for the 3D , it cannot play 1080p videos at optimal framerate.
This is exactly why they should have just stuck with a dedicated HDMI port... Not to mention USB host is pointless with a TV because the port is taken up for the video-out.

my kernel is pusing 1080p @ 120hz (so 3d works on the your hdmi big screen) - verified working by both gsm and cdma users.
*per my personal experience and that of users posted their feedback on my threads
issue: it only works for some, not others
not sure if its a cable issue or a phone/hardware limitation that only applies to some phones
i personally am using a samsung cable - its the only cable that works w/ my phone @ 120hz
I will try your Anthrax kernel to see if it makes a difference for me. I was on test06 last week but I decided I couldn't deal with my camera preview and landscape gallery not working. Do you have a newer kernel up now that i can go grab?
test is the latest - and hdmi/mhl on most 2.17 based roms is borked ... due to the gpu issues im working on (same issue that affects landscape video and camera preview - all related)

[Q] Why is MHL interface so complicated?

I mean, I just cant get how its possible that this phone's stock ROM and kernel have a decent MHL support, and a super customized ROM, like Cm, AOSP, AOKP (wich all of them include awesome tweaking capabilities....) doesn't have it?
I mean, most of the stock parameters appear on files that are editable on Notepad. So, is there any one referred to MHL setup? And so, why don´t you just "paste" it into the root of a custom non-stock ROM to get that feature available?
Today I got an "advance" in my hopeless quest on getting a decent MHL look on my phone (for those who read my older threads...). I recorded my phone screen using Screencast app on a Dead Trigger playing session (wich looks horrible on my HDTV through MHL...). I was expecting that the recording has a decent quality, but due to the S2 hardware capability, I could get an awesome, sharp and smooth looking recording of my game.
The surprise came, when I plugged my computer on the TV. The default output resolution is 1080p, and in the TV, it looks "too" sharp, with a little colour and quality loss. But in windows 7 I can change it, so I did it to 760 (or something like 764) and voilá, suddenly the screen was showing my desktop flawlessly (not losses of any kind), so I decided to watch the recording of the game in my pc through Skydrive... and the results shocked me. The quality was perfect. Super smooth, fast, awesome looking 3d graphics.
Now, thats a progress. A video in 1080p output resolution looks bad through DNLA, and HDMI out (on pc); the same on 764 looked perfect (and both were faaaar too better than the same video on MHL...)
So, it seems that lowering the MHL output to 764 would be a kick up on quality. Will be possible?? Only masters can talk...
Thanks for your time and hope you can bring your light on my research.

Roms like aokp and cm10 can't use mhl because of samsungs proprietary crap, so you need to use a stock based rom if you want mhl.

You are right. It is due to the parts being closed source and not part of the AOSP source code. Without this there is nothing the devs can do to make it work.
And exploring the phone's files? Maybe a trial or error test to find the MHL related parameter?

As this is very dependent on the kernel even if you could find the files without the proper kernel source code there is nothing they can do. Until it becomes part of the AOSP code there is little to no hope of it working properly
Now THIS is a progress:

It looks like a solution, just editing the build.prop
some ROM not supported HML as NFC
Actually, I added that line and now my phone is MHL compatible, although its ROM originally wasn't.
But only to play music and videos, nothing more shows on screen.

MHL Lag

So, I picked up the samsung smart dock to play emulators, games, etc. but I'm getting some pretty bad lag.
Its not choppy, just delayed from what I see on the TV.
I've tried enabling game mode on my TV so the post processing is disabled, and I've tried just using a plain LCD monitor but the lag is still there.
Recently, I switched to the beans rom and that helped the lag a lot, but, its not quite gone.
I noticed that in this forum: http://forum.xda-developers.com/showthread.php?t=1712902 a kernel dev was able to change the refresh rate to get rid of the lag.
Do any of you know of any other ways to get rid of the lag or should I wait to see if a dev here incorporates something similar?
If an dev here can't fix it, then its impossible lol.
Ok OP I have the official MHL adapter on it's way to my house as we speak, hopefully it gets here in the beginning of next week so I can test and confirm what the problem is.
The post you linked to describes a refresh rate issue, which is not the same as lag. What's happening for that guy is his screen output is being capped at 24 fps which is horrible for gaming/interaction.
Once I get mine hooked up and tested on my monitor I will be able to confirm exactly what the phone is outputting and from there we can see what needs to be fixed.
I thought so, but, wanted to be sure.
Thanks for taking a look at the issue, any help is appreciated!
What I've experienced, is that on stock, lag was terrible, close to 500ms.
On CleanROM 4.0.5, it wasn't much better.
On Beans it was much better, closer to 100-200ms.
I haven't tested with my S3 yet, but I suspect there may be similar lag since the hardware is similar.
Are you sure it is not the TV? I'm not familiar with MHL but maybe it is a defective dock.

It's not the TV, verified with various other inputs, Xbox and PC on HDMI. I also verified the galaxy with a separate LCD with no post processing abilities using the official Samsung MHL adapter.
