Is it possible to connect the Galaxy SIII to a portable USB monitor? There are a lot of portable monitors with HDMI input (5" to 10") using for camera but they are expensive. Some cheaper monitors only have USB input. I wonder whether is it possible to connect the phone to those. If yes, how about the sound, bcz cell phone only has one mini-USB output that can be used as HDMI output?
How about connecting the phone to a cheap portable HDTV?

I just got the genuine samsung MHL adapter for my Galaxy s2. The touch is not working properly when i connect it to hdmi cable.
It showing the mobile stuff on my TV but the touch is really lagging and i am hardly able to use my phone when connected to hdmi cable. Is there any specific hdmi cable required to make it working or there is some setting i can adjust to make it workin?
I recently upgraded from an x10 to my shiny new ion and just ordered a micro hdmi cable to output pictures/video to my hdtv. I was wondering if it would be possible to also connect a USB OTG cable to the phone so that i could use a mouse or game controller through the USB port for playing games while outputting the video/audio to my hdtv?
Thanks,

I would like to know this as well, and it would be nice to have some recommendations for apps that can run different usb devices.
This info is from here
http://www.xperiablog.net/2012/01/15/smartdock-for-xperia-ion-hdmi-multimedia-docking-station/
"The SmartDock is broadly similar to the LiveDock docking station, although it has one main difference – the inclusion of an HDMI port. This means that you can dock the Xperia ion into the SmartDock station, connect it via HDMI to your TV and look at photos, watch videos, listen to music or even connect a keyboard/mouse using the two onboard USB ports. It also, obviously, will charge your phone too."
If the dock can do it, should be good to go.

I got the DK20 dock for my ion. The only gripe I have is that it doesn't draw enough power from a PC's USB port to charge the phone. You need to use the plug that comes with the dock or the ion. (I use the ion's charger at work and the plug for my x10 at home.)
A neat upshot is that the USB ports on the back can also be used to charge other devices or host a Flash drive for more storage. ES File Explorer handled the additional storage flawlessly.
I haven't tried a controller by USB yet, but I got the Sixaxis app from the Android Market. Maybe this will make it easier to pair...

I tried it out yesterday.
It really works well. Was able to play "The World Of Goo", using the mouse and viewing it on my samsung 21" monitor which has an hdmi option.
The mouse works pretty well. If you have a usb hub you could even connect a usb keyboard, which works well too.
Hi
I had a look at the MHL wiki;
"Samsung’s Galaxy S III/ Note 2 can power the MHL-HDMI adapter (when used with a non-MHL-compatible-TV). 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"
......does anyone know what this means? Can the Note II output the signal to HDMI without using external power.
We all know that it can connect to a regular HDMI socket but the adapter requires external power.
I know that when using a passive MHL cable it does not require power when connecting to a MHL specific HDMI socket. These cables are quite difficult (and expensive) to get hold of but Kanex does one. Furthermore, only very modern TV sets have a MHL specific HDMI socket.
After reading the wiki......I'm now wondering if the Note II can connect to a regular HDMI using a passive MHL cable without requiring external power.....but the wiki is not clear.
Anyone got any ideas?
I've just bought official S3/Note 2 MHL adapter and it doesn't work without external power source.
HDMI standard requires 4 TMDS wire pairs (R, G, B, CLK) plus additional control signals.
MHL uses a single wire pair for data, on which the R, G, B channels are multiplexed. That pair is shared by the USB OTG connection.
So my understanding is as follows:
In order to use a MHL passive cable, you need to have a MHL-enabled TV, and connect that câble on the MHL compatible HDMI port.
Otherwise, the TV won't recongnize the signals.
Currently most TVs are not MHL-enabled. So you need to use a bridge between the device MHL output port and the HDMI TV input, in order to convert the single multiplexed data pair in the 4 data pairs. And that requires powered.
The Question is why do we need an external power supply, instead of using directly the device power supply...
Too high power consumption ? Technical limitations with MHL v1.0 standard ? or No one would like to try that ? ...
Also, for you reference:
The Kanex cable you mention does only work with those MHL-enabled TV, as stated on the product page.
Samsung offers now a new MHL v2.0 adapter designed for the GS4:
http://www.samsung.com/us/mobile/cell-phones-accessories/ET-H10FAUWESTA
The new feature with that adpater is the fact that you do not need to connect the wall charger to it (unless you would like to charge the phone).
Although that is clearly stated on samsung's site that this adapter is compatible with GS3 and GN2, that is also clearly stated that only the GS4 supports this new capability because of its MHL v2.0 compliance.

I couldn't 100% confirm that, but after some web searches, that has got clear for me now that it is a MHL v1.0 standard limitation.
MHL standard was derived from the HDMI standard, and was intended to allow a mobile device to send audio/video streams to a display device, while the display device can send basic control command to it. In addition, It was made possible to charge the mobile device thanks to the display device power supply.
So obviously, the standard was designed with a power supply provided by the display, not the phone.
And as for non MHL compatible display device, that seems it was not the first priority. Bridging between the phone MHL output and the standard TV HDMI input was a workaround, requiring an external power supply source.
With MHL v2.0, they have enhanced charging capability, and that seems they have covered the "bridging" case.
MHL v2.0 compliant phones (like GS4) should be able to power supply the bridge adapter. That tends to be confirmed by the fact that the new Samsung MHL adapter for the GS4, supporting v2.0 standard, does not require an external power supply if used with the GS4, but needs one if used with the GS3 or GN2.
Has anyone confirmed whether the Galaxy Note 3 will be MHL 2.0 compliant? I would guess yes, especially if the GS4 is already 2.0 compliant, but I just wanted to see if there was a confirmation of this anywhere. I would love to be able to display to HDTV without the need to separately plug in the power, because many times, the power outlet is not within easy reach of a monitor or HDTV.
I guess we will know for sure very shortly!
Confirmed: GN3 will have MHL 2.0, which should mean that we can connect the HDMI cable directly to the adapter without also having to plug in the power adapter. Woo!

yeah, u can use micro usb to hdmi adapters or use samsung allshare cast dongle which does this job wireless.
3 options:
Samsung MHL adapter.
you plug your charger and an HDMI cable into the adapter, adapter goes into your micro usb port.
pros: small, cheap.
cons: can't use external storage, doesn't fit with many cases/covers, only works with adapters made specifically for the S3/4 and note 2(generic MHL adapters have less pins).
smart dock.
works the same as the MHL adapter but has some extra functions.
pros: comes with its own charger, adds 3 USB ports for mouse, keyboard, and USB storage.
cons: desktop mode(plug in a mouse, phone screen turns off) is slow, without a mouse your phone is stuck in portrait for rotating apps, expensive.
allshare cast dongle.
little box that connects to your TV through HDMI and comes with its own power cable+wall plug.
you can keep the box plugged in, connects like a Bluetooth headset but using the allshare cast menu(Wi-Fi) instead of Bluetooth.
pros: wireless, otg cable, charger, and data cable can still be connected.
cons: compression artifacts show while playing heavy games or when playing unsupported video files(software decoding), tricky to get to work when you have cwm installed, even with Wi-Fi disabled your phone may randomly connect to your network causing the allshare connection to be reset, expensive.
best choice would probably be an MHL adapter.
allshare cast can be interesting if you have other recent Samsung galaxy devices(camera, s3/4, note 10.1/8)
smart dock can be interesting if you want to use your phone as a desktop computer.
So I attempted to connect my device to a portable monitor via a USBC docking station. The monitor has a micro HDMI in and a USBC port that supports video. The docking station has an HDMI out port that I was attempting to use.
My set up was: I connected the Redmagic 8pro to the docking station via USBC, then the docking station to the monitor via HDMI to Micro HDMI.
The phone is saying that it IS casting but I am not getting any video on the monitor.
I have tested just connecting the phone to the monitor with no docking station using a USBC cable only and it works just fine.
I tested the dock with a different device with the same set up as before and was able to connect with no issues.
Obviously I can just connect via USBC and call it a day but I would like to use the dock because I would also be able to charge my phone and connect USB peripherals as well as the monitor.
Does anyone have any idea why the I can't connect using the dock and the HDMI connection?
I have tried with 2 different Steam Deck docking station from Amazon and HDMI was not working.
I am suspecting a usb alt mode driver issue. The phone also gets a bit lost like charging - disconnected -charging -....
The ethernet, storage, keyboard mouse are working but in the Android logs I dont see any HDMI related logs, so since I was able to build the Linux kernel (with the DP alt mode module), I have to flash,test again but it takes time for me .
I am a bit disappointed that it does not work from the begining, but it is a good step that Nubia is releasing the kernel source code.
The only solution I am aware from reviews is to use a direct HDMI to USBc adapter
Thank you for the reply. It is very unfortunate because without being able to connect to the dock you cannot charge the device while connected to a monitor. Have you tried using any non Steam Deck docking stations, just out of curiosity? I am considering trying a couple. It is probably a waste of time but this is a very frustrating issue and I have not been able to find anything close to a solution.
An Update! I found a dock that I was able to use to successfully connect my device to my portable monitor. I will link all of the hardware I am using, please share with any other users attempting to use a similar set up.
