MHL Performance Abysmal - Xperia Tablet Z General

I've tried two generic 5-pin USB -> MHL adapters and found the performance to be horrific. I can get them plugged in properly despite the port cover trying to stop me but I found the whole experience to be extremely poor.
Would using a branded MHL adapter help? I've read that the GPU has twice the work load rendering the output on the XTZ screen as well as out via the HDMI but really, they're both 1080p displays so shouldn't it just be a case of mirroring rather than rendering two 1080p displays?
I've tried SNES, PSone and just Chrome browser and the experience is still bad. Low framerates, sometimes the display will go black for no apparent reason for a second, other times it will stop working and I'll hear a screeching coming out of the TV speakers and garbage display.
Would a branded (Samsung, Sony) MHL cable give any better performance or should I just give up and stop trying to use this tablet on the TV? One of the only reasons I bought the tablet was TV gaming (as a portable emulator box of sorts). It's just infuriating because it works perfectly on the devices screen
Does anyone know if a jailbroken iPad with TV output running emulators has the same performance issues or it just works?

I have got the Samsung MHL adapter and it's the same experience for me, low frame rates in general, so I gave up using this tablet with a TV. Maybe with the screen mirroring could work better but I haven't tried it.

I have the Sony branded one. I will test it out some and see how the performance is. Haven't used it much with the tablet as I use it with the Xperia TL mostly.

Could you tell us whether HDMI-CEC works with the Sony one please? I have a third party adapter and I can't control the device from my TV remote, which makes it useless to me.

I use Samsung-branded MHL adapter and CEC works with no problems.

Don't have anything to comment on your questions as I don't have an MHL plug at all, though I might have some ideas on poor performance.
This might be due to the fact that the tablet forces [email protected] refresh rate (defacto standart for movies and mostly any other video). This way you're getting 24 FPS only.
Why do I think it's doing so? Because Sony Xperia S did the same with its HDMI out. There was a way to force 60hz refresh rate and get decent fps through the service menu (*#*#service#*#*) but they killed that workaround after the 4.1 update. You can try this workaround on Tablet Z.

THANK YOU! I researched how to get into the menu (funny place hidden in the contacts app [A guide], I poked around and found a setting which can be changed after the MHL cable is connected (power cable and TV powered on) - as expected it was set to 1080p24 so I put it to 720p60 and like magic all of the apps I've tried so far run at around the same speed as the tablet on its own, Sonic CD looks magically smooth as well as the SNES emulator is playable. I'm going to make a YouTube tutorial/demo later today or tomorrow.
I'm just confused why Sony would choose to bury a setting this critical to the performance and public perception of the device in the service menu and not the Xperia menu in settings, they could even have descriptions "When MHL is connected the device will run at 1080p24 which is ideal for movies and photos, 720p60 is ideal for gaming and using the tablet normally".

Glad this helped you. Yeah, makes little sense. It makes even less sense if you consider the fact that I wrote to them about this issue and even got response with thanks and promises to fix it. And here we have absolutely new device with the same problem :\
What's more interesting is that [email protected] is a pretty niche mode suitable for video/movies only (and even then it's not for every format). Any interactive productivity (such as games or simply ui navigation) is almost incompatible with it. That's why 60hz is an approved standard. I wonder whose was this great idea at sony to make 24hz a default mode.
...so you're saying [email protected] is not even available now? It was available at xperia s.

The case is that MHL standard used in XTZ does NOT support [email protected] Check the specs

I have another Problem with MHL and Docking Station.
When MHL-Cable is pluged into Micro-USB you can not plug Tablet Z into the original Docking-Station
You have to flip 180° . BUT screen does noch turn with MHL connected !
Any Idea how to use MHL WITH Doking-Station ???

Does the LiveDock Multimedia Station support HDMI output on the Xperia Play?

I have done my research and can't seem to find a solid answer, has anyone had the chance to test one, or recieved an official response from Sony? Cheers
Nope, consumer versions of the Xperia Play do not support HDMI out, even on the LiveDock.
The only Xperia Play phones that support HDMI out are dev phones.
The current dock (DK300) has no HDMI out support but I believe there is a new dock coming sometime soon that will support it.

@ dousan. As you can see in this video. It defo only uses the USB port for HDMI out. Not the HDMI port like we was talking about in that other thread. The HDMI port on the Arc is on the top like the power button on the play. The dock has the HDMI port on the back
http://www.youtube.com/watch?v=Xhr6AuPLwmU&feature=related
But that is not how it connects to HDMI. The dock does not support HDMI. It is the phone hardware.
As in the other thread there are photos of how they connected it to the TV.
The USB device connects to the device, the charger connects to the device and uses that same cable. The then connect to the HDMI on the TV via the HDMI port on the phone.
The Dock is not an all in one solution.

Yes but recently the same marketing division said :
I can confirm that the following is available for the Xperia Play based on your question's once the update has been released.
Enhanced camera capabilities from Sony including 3D sweep panorama
The software upgrade enables consumers to turn their Xperia smartphone into a mini-mobile PC by connecting USB peripherals (mouse, keyboard or game controller) to Sony Ericsson LiveDock™ multimedia station. Connect the smartphone to a TV via HDMI to get a big screen experience
I can also advise that there are currently no plans for HD 720p recording for the Xperia Play.

It's a hardware limitation, they took it out of the specifications before release.
The LiveDock would basically act as a pass-through, not a hardware solution.
It is possible to get video through the USB port, but at very low refresh rates, like 1 frame per second.
ASM is one tool:
http://code.google.com/p/android-screen-monitor/
And there are other remote desktop applications that can produce video out through USB with slow refresh rates.

The thing that catches my eye is that he clearly states it's for the play but the section about hdmi and USB peripherals it only says xperia smartphone's, not xperia play? That's confusing me.

Yeah but it also has Irda test in it, so I imagine this tests are standard, and not especially designed for the Play.

[Q] HDMI delay from tablet to TV

My setup: wired USB Logitech gamepad hooked up to Iconia, which is hooked up to TV by HDMI, playing emulators.
I've noticed a small 'delay' in a few games I've tested, Mario for NES for example, from when I push a button to when I see the jump animation. It's not a horrible delay, but it's noticeable and I can't figure out if it's being caused by the emulator, the controller (brand new), the Iconia, or the HDMI. I haven't played these kind of games with a controller in so long, maybe I just suck at it?
Is it even possible that the delay is because of the HDMI output to the TV? I've seen so many people talk about playing games this way I wouldn't think so.
Well, when not hooked up to the TV, do you have the same delay on the tablet's screen?
I just tested it, and there is a slight millisecond delay from what I see on the TV compared to what I see on the Iconia.
As miniscule as that seems, it is noticeable on some games. Knowing this, is this something that can be fixed by perhaps a different HDMI cable (yeah I know, they're all the same pretty much), a change of settings, or is this something you just have to live with?
'Cause it's really a let-down
You're running an emulator on an Android device, and you believe it's the HDMI cable giving you a millisecond delay?
Really?!?

Why yes I actually do believe it might be the HDMI cable, among other possibilities. It doesn't matter whether it's an emulator or not, there is a delay.

I shouldn't have worded it that way - the delay happens whether I'm using an emulator or any other program. It's not specific to emulation, it's the whole device.

Now that it's clear, I can see as how you might believe it's related to your cable, even though that's most likely not the issue. Have you tried another cable to rule that variable out?
Apparently certain TV's are better than others when it comes to input lag.
I think mine's one of the problem children. Case closed, I guess. Nothing I can do to fix it.
I also hook up my iconia via HDMI and play emulators. I noticed a small lag as well. Its just barely noticable
Sent from my A500 using Tapatalk
typically TV's do some processing on the input image, this takes some miliseconds up to 200 milliseconds. No problem usually, but now you see both source (Iconia) and target (TV) and notice a small delay...
Try switching off all 'enhancements' on the TV, that may show some improvement...
The delay is not caused by a cable, unless it is hundreds of miles long
It's only a 6 ft cable. And the TV has no fancy options to turn off. It's a budget model (which is why I have this issue to begin with).
I tested some more, and it doesn't make things unplayable, I'm just used to millisecond timing on games like Mario and so I have to re-learn how to play. Some games are better than others.

Finally Solution to HDMI port (CES 12)

http://www.engadget.com/2012/01/10/analogix-slim-port-technology-lets-you-connect-your-phone-to-you/
Sometimes, the simplest ideas are the best ones, and Analogix Slim Port technology certainly qualifies as both. It's a cabling solution that allows you to mirror what's on your phone or tablet's screen to your TV via microUSB -- instead of needing an extra HDMI or MHL port. Analogix's secret sauce is on a chip embedded in the jack portion of the cable and because it's based on DisplayPort technology, it can connect using HDMI, VGA, or DVI connections. Of course, as an OEM, Analogix won't be selling the cables when they go on sale this summer, but retailers like Belkin and BizLink will probably be put one in your bag for around $20 or $30 bucks.

So now we can connect our beloved Play to that TV XD
I think it doesn't work like that... you have to have the tech on your phone (Mobility DisplayPort (MYDP) digital interface) it then allows uncompressed video/audio from a phone over display-port and also allows usb transfer modes

Do you think that TV out is just going to magicly work when you plug in USB LOL
FYI your usb port is never outputting video lol. you would have to run some type of program to do it and that will use CPU power
When have you ever plugged usb into your PC and a message comes up "Would you like to mirror image on your screen?"
You guys know the PSP actually had software written for it that allowed USB mirror to desktop and it lagged the device so badly most games weren't playable anymore

check the spec sheets. Also, notice that the Play has Dev units with HDMI out and they don't lag a little.
A bit off topic, but I don't think I ever posted this while I was analyzing the play for HDMI.
According to the kernel, the Dev plays have this chipset and all Plays have the drivers for it: http://www.analog.com/en/audiovideo-products/analoghdmidvi-interfaces/adv7520/products/product.html
And this can be seen on the Dell Streak: http://www.ifixit.com/Teardown/Dell-Streak-Teardown/3512/2
Now, I tore apart my Play (when I had it), and I can confirm that that chip is NOT on my retail r800i. This means that there is no "hidden" port or some unfilled solderpads that can be used to attach a microhdmi. There is NO support on the retail motherboard for it. You can't even buy the ADV7520 chip because there are no space on the retail motherboard for it.
There's no chip or hdmi port on the play I've watched dissasemblies of all types r800a,x,I

I don't have a theory, as I don't care one bit about TV output of any kind. However, you mentioned that the PSP wasn't powerful enough to beam out content, which is not a problem in the Xperia Play (or Arc and Neo for that matter).
Why do people keep saying "the play has no HDMI transmitter" if you read the OP, with this cable the HDMI transmitter is built into the jack, the device does not need one

The adapter is probably accompanied with an app. Although the app would need root acces, atleast I think so.
whilst i think this would be an awesome piece of kit if it works as intended, im a little curious as to how it actually works, afaik the cpu sends its work to the gpu for output, the gpu processes it, and outputs it to the display....so how exactly does the usb port get the information from gpu...maybe easy with root access on one device...but making it work on a wide range of devices would be crazy hard.
im not gonna straight up bash this, because they have said its a vendor agnostic solution, so im assuming they have worked out some technical magic with no downsides to pull this off. I'm all for being proved wrong, i just want to see it in action.

First statement is a bit overstated.
By capability the gpu in the PSP has a fillrate of 30 million polygons/s
I believe our Adreno has 52 mil/s
Plus instead of the capability I believe it was the limitation of USB speeds that affected the computer mirroring software.

I use it while teaching classses on less lethal munitions. I can walk around the room and wirelessly broadcast my screen to the projector. Thus the students are able to see my tablets screen exactly as I move thru the presentation.
And if you broadcast from a laptop(still learning how to do this part from the tablet) if the student have their own ipad/ android tablets... it will broadcast right to their tablets in front of them.
I think it is really going to bring the quality of my classes up to a whole new level. Not sure if this is what you were talking about but I thought I would throw it out there.

It is the samsung hdmi adapter. and the samsung hdmi to vga adapter. I am thinking that it is detecting the adapter and lowering the quality of the resolution.

I have just started to use the GNote to give lectures. I use the Allshare Cast Dongle to make the wireless connection to the GNote. As all my lecture theatres are still using old tech data projectors I had to source a digital to analog converter. This takes the HDMI signal from the Allshare cast dongle and converts it to analog. The converter has a female Dsub connector which the vga type cable form the data projector can be plugged into. I was worried it might not work that well but it has exceeded my expectations. The quality is great and the being wirless has much potential. You can get get the converters on Ebay. I suspect this is quite critical so I got a decent one from Startech.com.

It is the samsung hdmi adapter. and the samsung hdmi to vga adapter. I am thinking that it is detecting the adapter and lowering the quality of the resolution. That is the only think I can of happening. I have the allshare dongle coming in today and maybe this will work but it will still have to go through the adapter so I am not confident.

Thanks for this info. If I've understood well Teqavit Wips 1000 could work as an alternative to Sansung's Allshare Cast Dongle.
I've Googled it and found out the producer page, but I didn't find info about:
What's its price range compared to Samsung Dongle?
What app should be run in the Note to broadcast its screen to the receiver?
EDIT: Possible answers to Q2 WiFi-Doc? MobiShow?

I checked. Price range 300ish to 500ish . I called the company and they said there are two types one that broadcasts 7209 and the other 1020 p which is the 1000. He said because of the higher resolution the refresh rate is low on the 1000 and best on the 340 or the new 510. Price is too steep for me for out of pocket especially if image is low quality for ppts. It may be an adapter issue for me I am exploring what might be best. Seems prices are all over 18 to 50$$. I would hate to have the ipad one up us on this!

(???)
Before I got the Allshare Cast Dongle I evaluated MobiShow and Wifidoc. They work OK over wifi but they are far more limited compared to the Allshare Cast Dongle. The Allshare Cast Dongle mirrors the GNote screen which is its massive advantage IMO. Just wish it had a snappier name...
I just used it again today to demonstrate to the Chief for a court room project we are working on. I streamed a movie to the HD TV using a HDMI cable from the wips1000 to the TV. The picture was great and there was never a hang up. I also went through three power point presentations and had absolutely no problems with resolution or lag or anything. And if you use Polaris office to do the ppt presentation or office suite hey both have the ability to use the S pen to underline or highlight things on the presentation slides during the presentation.
Cost is steep 440 for the wips1000. But it is very small and portable and if you will be traveling it's worth it.
The app for mirroring the tablets screen to the TV or projector is mirrorop ...
And the wips1000 will also interface with SmartBoard if you are presented with one of those when your teaching.

Another plus and part of the cost and why I chose the wips1000 over other options is that it broadcasts its own access point. With the other dongles you have to connect to an existing wifi network. The wips1000 and the 350 and 450 all create their own wifi network access point.
Many times when I go train another agency their wifi is locked down and the IT guys has to enter my laptops Mac address in to their network to give it connection permissions. A real pain in the butt ... but the wips series devices create their own wifi network, no internet mind you, but that's how you connect wirelessly. So you aren't dependant on access to an existing wifi network.
Somebody above mwntioned uaing existing wifi with a dongle witj mediocre results. I suspect thay even if you did have access to an existing wifi network and were using a dongle, your performance could be hampered by other traffic flow on that network.
Just food for thought.

HDMI issues real? (about to buy)

First of all, I've read the prior threads, but my question is contextual, so please bear with me.
I currently have an Acer 500 which I use for web, email, RSS on a daily basis. On trips the HDMI-out is a lifesaver in the evening at the hotel, as anyone with kids will attest to.
In the spirit of Father's Day the Boss has authorized an upgrade, handing the A500 down to my kids for homework use.
I understand there are 2 HDMI issues with the N10:
- Scaling
(fixed in Videos and MXPlayer, and possibly with newly discovered code/app)
- Compatibility
no sound via HDMI
no video with certain TVs
I don't care about scaling, and can live with letterboxed video.
Just how bad are the TV compatibility issues, really? I know HDCP can wreak havoc between devices, but both the Acer and SGIII have worked well with every TV I've tried them with; I have decent cables/adapters. Is the problem a connector issue, or is there an inherent issue with the N10 HDMI pathway hardware? If' it's just the plug, I can return it until I get one that works. If it's the intrinsic hardware, this would be a show stopper for me.
Again, I know the prior threads on this issue, but I'm trying to gauge if this is an unfixable issue for most people.
TIA.
From what I've heard and seen, compatibility with older Panasonic-based TV's (VIERA for example) might be somewhat bad. The VIERA TV I have has working video, but no audio. Some no-name HDMI TV my friend has (can't think of the actual name) works fine for both video and audio.
Not sure if there's any general rule or anything that determines compatibility though, or how other devices handle TV's...

HDMI with video and audio work perfectly fine to most things, the problem is not that HDMI simply doesnt work but rather that certain companies do not conform to all standards properly and this causes compatibility issues. As Espionage said, Panasonic's are the big one with no audio, and Sony Bravia's also tend to have issues. I use my Nexus 10 to go into my Onkyo receiver which then passes video on to my Panasonic plasma and audio goes to my speakers. It works perfect except for the obvious scaling issue because it is not trying to send a 1080p signal. That is easy enough to live with or you can do the workaround to make it perfect if you really care that much.
The thing that sucks though is just that hotels have all sorts of TV brands, so compatibility will just be hit and miss depending on which models of TV they choose to have.
Most of the time , hdmi doesnt have sound .
Many incompatibility tv s .
I personally have a pan 30gt ... No sound .

No problems at all using it with my LG TV.

When you say that the video is fixed in MXPlayer, where did you see/read this? I would be interested to know because I heard it was coming but for me the scaling is not yet fixed.

I have a Panasonic and no issues with video or sound using the N10 over HDMI. FWIW.
Bought the '10, loving it. HDMI works fine on both Sammy's at home.

and what is the price ? im looking for something in good price i found some from connection lab and try to find out if its really good
Guys, Can anyone confirm if Nexus 10 needs to charging for the HDMI out to work? My nexus 10 doesn't output via HDMI if its not connected to power.
I get no sound through my Viera too, it's pretty damn annoying actually. Regardless of their HDMI 'compatibility restrictions' or whatever, all other devices work correctly with it including my Galaxy S3 and a whole assortment of cameras, PC's and gaming consoles. Hoping for a fix in 4.3.
connectionlab is good!
So far so good. Couple of days ago I asked you about connectionlab brand, but since I have no responses I thought I'll give a chance and bought ConnectionLAB HDC-10 Premium 10m HDMI CABLE. Is beautiful!
I have to say that I'm really pleased with my new baby. Seriously, you get a good quality for a good price. My friend bought a cheap hdmi cable and sait it broke down into 2 after 15 minutes! But this one from connectionlab seems like a good choice
