[Q] HDMI cable

Anyone know where one can be brought? also why have I read stuff about the s2 having mini usb? it doesn't it has the same propriety connector as the galaxy s.

It's MHL. It's the supposed new 'standard' for connectivity. I think most devices are using that connection nowadays. Last I heard was Clove saying the MHL adapters won't be out until June.

really? so the original galaxy s had mhl as well? Any suggestions on what to do with my fancy new phone? so far apart from being super quick it just seems like a sleaker bigger galaxy s, I cant think of anything my galaxy s couldn't do :S
Oh I know I'm gonna see if the wii mote works on this thing

I can't find any evidence that it did.

It's the new standard, but that doesn't mean older devices support it. The SGS2 is one of the first AFAIK

But nothing on the market will currently work? HDMI out from a mobile is just supercool!

I have both an sgs1 and sgs 2, my charger fits the micro usb (the only i/o connector) on the phones, perfectly

The connectors should be the same on the S1 and S2, but only the S2 is MHL compatible.
I think MHL can use any 5 pin connector to send an HDMI signal while receiving power for charging.
I'm not sure if you'll be able to use the MHL HDMI out and USB at the same time, but I hope this is possible.
I'm also guessing that the adaptor will need to be a clever one with circuitry rather than a passive adaptor. Does anyone know if this will definitely be the case, and if so I'd imagine it'll have cost implications! Hope I'm wrong and a passive adaptor is possible

Coming from a LG Optimus 2x, that came with a Micro USB ---> HDMI cable. These are available from Ebay for a GBP 10 - would these work?

Yea guessing its just MHL compatible as the old port was usb compatible. Thats annoying, with all the talk of this new standard usb-hdmi port I was assuming it would use a standard connector and not a proprietary one.
It stupid really if all manufacturers used the same connector we wouldn't have to have multiple chargers/docks/cables

You can't use the USB port for MHL and USB functions at the same time, this is confirmed (if you search for MHL at youTube there is a great video with a person from the MHL consortium explaining it).
To badasschris: this isn't a proprietary port. Samsung, Nokia, Sony, HTC, Toshiba, and quite a few other partners are involved with it, it seems likely to become the standard for mobile devices (iPhone aside, I am sure Apply will continue to push their proprietary ports).

Are you absolutely sure it isnt proprietary? Why I am getting confused is because it has the same port as the galaxy s1 and I heard nothing about that being a standard port and you always have to buy a samsung charger not a [standard port] charger e.g. mini usb charger for any devices which have mini usb. So you are saying at some point the other manufactorers will have the same port and I will be able to use my galaxy s charger to charge them?

Galaxy S is a standard micro USB port, and lacks the MHL connection, its not proprietary at all, I use several non-Samsung cables to charge the phone in my car and from PCs. Most manufacturers, Apple excluded, use micro USB charging now.
The port in the Galaxy SII is not the same as the Galaxy S, as it has MHL connectivity in addition, but its function as a micro USB port for mass memory and charging is perfectly standard, and doesn't require special cables or connectors of any kind.

lol I had to thank you there I've been a right plonker. I remember seeing someone say the origional galaxy s was micro usb and then when I saw it I thought that't not micro usb. It just clicked I have been getting micro and mini usb confused. When anyone said micro I immediately assumed mini
Glad I got that sorted.

That sucks. I was hoping to look into making a tablet dock that used a USB capacitive touch screen & HDMI output for the screen.
A laptop dock using Bluetooth for the keyboard and HDMI for the screen would still be possible, or a tablet that used Bluetooth for the touch-screen.
This phone is powerful - it's annoying not to be able to use the hardware for more than just a phone.
I reckon Motorola is thinking along the right lines with the Atrix, and I hoped other manufacturers would be too, but this combined port indicates Samsung are probably not.

Plus you have the added fact that samsung like to mess with bluetooth meaning many devices wont work with it. I really hope the bluetooth situation gets fixed somehow as this device paired with a screen and a bluetooth keyboard/mouse and game pad gives you a portable computer / games console. without it its just an amazing phone

This should work perfectly with bluetooth mouse and keyboard, my SGSI does. It should also work with a Zeemote, unfortunately it doesn't have enough buttons to be that good for using in emulators.

I can confirm that the igo stowaway bluetooth keyboard works fine w/the SGS2 in case anyone's curious

MHL & USB host

Anyone know if it's possible to use MHL in conjunction with a microUSB to USB host adaptor to output to HDMI and access an external USB drive at the same time? That'd make the SGS2 an amazing portable media unit.

No, it is not posible. Its an either/or connection to the micro USB port.
Shame, because as you say that would really be a great thing. MHL consortium are considering a number of improvements to the 2.0 MHL spec, so in future devices this may be a possibility.

So MHL can't be used when I'll plug a USB-Hub?

No, sadly not.
It's a shame - for now I'd prefer micro USB & separate HDMI port so USB can be utilised as well as an external display.

As would I, and a lot of others I suspect.

But you've got 16 GB memory and can copy your stuff to the memory and watch it later via MHL on your Flat? So this is not a big problem, I think

I would use allshare to stream the movie or whatever to your phone from a laptop and connect the phone to TV via the MHL HDMI adapter...that way you have access to ur laptop's data without being hardwired to it

Not that I'm aware of...

I bought one from Ebay and can't really do anything good with it. Display shows briefly for 3-4 seconds on TV then disappears again. Don't know why.....I hope it's not the device itself because I tested 2 phones, they were bought at the same time, but none of them would work correctly....

If by generic you mean a not samsung one or one not dedicated to the SGS2 then i actually use a one, from ebay or someting like that, everything works perfect you just cant forget to plug power to it, and about the not working one, it seems mine gets jammed by gsm signal (i.e. when receiving a call), so from time to time the image disappears in a blink of noise, maybe that is your problem too, try it in airplane mode.

Oh, I think I misread that question - I have actually used a generic one with my SGSII (a prototype from the MHL consortium) and it worked fine!

No, you can't, when the MHL is connected, the WiFi stops working, I regret not having bought the Optimus 2x

Uhm no. I've been streaming with WIFI through MHL no problem for MONTHS. Using the Original Samsung MHL connector of course.

I have to put mine in offline mode to be able to use the MHL adapter.....
As for USB-OTG no luck yet.....

On Amazon, Ebay, DealExtrem ... you will find adapters that can do 3 things at a time:
- output HDMI
- let phone work as usb host, so that you can plug kbd, mouse, and external HDD (second wifi card, wired ethernet ...); once you have the usb A plug, just pub a hub
- recharge the phone (what is not possible with the legacy short OTG cable).
+ read memory cards
Such devices are sold as MHL devices. Some MHL devices don't to all that.
Take care. MHLv2 is more complex than MHLv1.

Monobloc:
http://www.ebay.fr/itm/Micro-USB-Ho..._MobilePhoneDataCables_JN&hash=item258600844e
I don't like the monobloc version; I fear it's too heavy, and may help breaking the phone plug.
There are all sorts of OTG and MHL cables. I have seen OTG dongles as short as 4cm (monobloc), with small cable (8cm: 4-8€), with long cable (1.5m .... should be 7 feet), pure HDMI (passive cable, no card reader, 8-12€), VGA (including very cheap HDMI to VGA converter, 20-30€ ... including sound output). In some case, you need to buy accessories (extra power supply, extra uUSB cable, extra HDMI cable). Also seen a very cute hybrid card reader: http://dx.com/p/285865 (I love this product design, and I love this URL syntax )
Don't forget that there can be mistakes in item description.
Here I have described how to build an external battery:
http://forum.xda-developers.com/showpost.php?p=54036759&postcount=17
On previous phone, I just soldered additional battery to internal one; on my new phone, I will do something more complex, and more flexible.
Loosing power via OTG/MHL is not a fatality. Most phone have an other hidden power input:
généric, that uses the USB plug:
http://www.dx.com/p/reverse-qi-wire...arger-receiver-for-micro-usb-cellphone-312805
TRIPLE CHECK POLARITY; I took the wrong one; have to fold the cable.
So ... even if your OTG/MHL module takes power from your USB, and can not recharge your phone, the specific shell can charge your phone the other way So, you need to build an internal specific module:
https://www.youtube.com/watch?v=UK7PRJ4SiK0
S2 specific back shell, so called receiver:

http://www.alibaba.com/product-detail/QI-Wireless-Charger-for-Samsung-Galaxy_821969998.html?s=p
The SGS2 is not designed to accept wireless chargers, so, you have two options:
- solder and take the pins out (cf youtube) (do not solder coild to battery, or you could overcharge the batt, and burn your phone ... I mean, physically set fire)
- find an item that includes back shell + specific battery (exportprive)
Many recent phones have the internal connectors, so you just need to change the back-cover. In this case, the software will be able to know the charger is wireless (as opposed to AC, and USB; advanced battery tools will show those 3 possibilities). I believe the motherboard for my HTC One M8 is designed to have those pins, but I can't find the specific cover yet (maybe in a few months); only found it for M7.

Can I use MHL to display video output on my computer?

I have an acer aspire 7560, it does have an hdmi port, but I don't want to have to buy an adapter for something that I don't know would even work for video input. I want to know: is there some way that I can use a normal, oem supplied, usb cable for this and simply connect it to the computer, figure out some stuff on the ubuntu end, and just use my laptop as an external display?

Short answer: no
Explanation: your HDMI port is solely for outbound connections only, to a TV or monitor. There are very few laptops that have the ability to receive an HDMI input.
As for doing it with USB there are third party apps like BBQDroid and MirrorOp that will let you, but its nearly impractical for the Nexus. Trust me, I've been trying for over a year to get even the right ROM/kernel combo to maintain a reasonable lagfree experience using them and its hopeless. We don't have the power. Sure, you can do it. But don't expect to do anything without huge performance drops.

I have a new tv that supports hdmi, but it also has usb 2.0 in, and I do not have a hdmi mhl adapter. Would a normal oem cable work for that?

Nope. USB port on your TV is for connecting media devices with music/videos/pictures and does not support the feature your looking for.
I have had success using the Mirror for CM11 application by koush with Airserver on my PC. Info to get it here. You must join the community and beta before it shows up in Play Store.
It works over WiFi network so long as your PC has AirServer, which is an Apple app supposed to be for idevices but the app picks it up anyway. The free version of Airserver is only 7 day trial. It will slow your phone down somewhat, but not anywhere near as bad as other apps. I've used it some, and it works well. But it has limited use with only a trial for Airserver. Such a bummer there, but give it a shot for the 7 days and support it and koush if you it
Good luck

Hdmi screen mirroring via usb cable not working

Helped a friend buy this. We were watching movies via wireless screen sharing (miracast) and it was OK but kept stuttering and dropping WiFi.
So I suggested getting an hdmi usb-c cable with power charging (4k). I was very surprised when it didn't work! Tried everything including downloading dex to the phone.
Connected the same cable to my s8 plus and it worked beautifully (dex) !
So why not the Samsung a50? Never experienced this on any phone before and have been connecting to TV this way for 10 years.
Need a different /special cable? Or no go on this device and can only do via wireless?
Thx

I haven't ever used HDMI mirroring on a phone but as far as my knowledge of Type-C goes, you need USB 3.1 to support all the alternate modes including HDMI and DisplayPort. The A50 comes with USB 2.0, so there is no possibility of getting Display-Out from the USB port.

thanks for that explanation, I'm guessing this the same reason we can't use type c 3.5mm jacks?
by that respect, pretty much any type c 3.1 can output through hdmi?
Thanks,
Scott

Type-C as a standard is a mess. I don't think you are required to support alternate modes in USB 3.1, so I suppose there are USB 3.1 Type-C devices that still don't output video.
Regarding audio, there is Audio Accessory Mode for Type-C and the concept of active and passive headphones/dongles, so not all dongles will work.

samsung A50 simply doesnt support dex. only s8 s9 s10 and Note 8 9 10.
getting usb c to hdmi wouldnt solve your problem.
there is how ever one possible solution, which is the universal android usb to hdmi cable. it uses ezcast app (same app for wireless). mirroring your phone but wont display netflix etc on your tv.

Samsung A20
So, I know that the A-series doesn't support DeX, but I was hopeful that it might still have the capability to project to a lapdock (like the HP Elite X3 or Nexdock 2) via USB-C and display even crudely (so, not the fully optimized DeX-ified desktop mode, but maybe just a mirror?), ideally allowing for keyboard/touchpad input as well. Basically I'm trying to come up with a solution for my mom whose company is phasing out the laptop she's accustomed to working on in favor of these lousy Samsung A20s, which she's gonna have a lot of trouble seeing and interfacing with on such a tiny screen and without a full keyboard (she's in her 60s). The lapdock thing is the only idea I've been able to come up with (though, it sucks that the A20s don't support DeX), but I'm open to any other suggestions if you think the lapdock route is a dead end. Thanks!

The A50 doesn't support MHL(display out protocol) at all for some reason, which is quite disappointing. At least wireless display casting works well.

USB-C to HDMI Cable?

Any recommendations on a good USB-C to HDMI Cable? With Desktop Mode finally being an option in Q, I'm hoping to test it out when Q is officially released and we see some apps support it. Preferably with availability in the States.

Amazon basic have better option for this USB-C to HDMI, I'm using that work perfectly

Does it work as HDMI + USB or only HDMI?

Is anyone able to screen mirror Netflix,YouTube TV, Hulu or Amazon prime with the cable? I have a cable and it mirrors everything except those apps when I'm playing video.

I don't want to maybe start a new thread so I thought here - does anyone charge their oneplus 7 pro type c from their laptop/pc to type c on their phone? my ultrabook doesn't quite have enough ports for usbs. so I wanna take away my phone on a usb and use a type c port instead to charge it.
I see some type c cables are 3.1 or something. for charging do I need the expensive cables?

You guys won't be able to mirror those apps unless you've rooted your phone and found a way to patch the application to make it think there is no secondary display connected. The reason you're getting nothing from these apps is they detect the presence of a secondary display, and since the phone cannot comply with HDCP over the adapter cable (not supported), it will not display correctly (black screen where the picture should be or no display at all). I've had a phone in the past with a miniHDMI port and I've used a proper mini-to-full HDMI cable without issue to watch Netflix, but that was a straight HDMI connection with HDCP. Netflix and them take anti-piracy seriously, yo!
