[Q] Feasibility of accessorising toward becoming a netbook

Given that the I9100 allows keyboard, mouse and hdmi output, it would be great to rig it up to perform as a little netbook. So, one would require
a battery-powered LCD with HDMI input,
a seperate power supply (battery with micro USB output) for the HDMI adaptor (seems like that is necessary)
bluetooth keyboard and mouse/trackball/touchpad (since it seems you can't connect both USB and HDMI at the same time),
and possibly a ROM that would take advantage of such a setup.
[EDIT: scouring amazon reveals portable LCDs with HDMI input and many external phone chargers.]
So my question is, what is the feasibility of such a setup, given the necessary hardware? does the necessary hardware exist? has anyone done such a thing already (quick search on google revealed nothing)?

I don't think it would be feasible to do it. You'd need an MHL adapter which people say drains battery even when it's plugged into a socket, and an OTG cable and afaik you can't use both at once. Bluetooth mouse/keyboards would further reduce the battery life.
Not to mention with all of this you'd need a fan of some sort to keep everything cool.

Just buy an ipad or one of the countless droid pads and a nice bluetooth keyboard.. you probably don't want to carry a screen larger than 10 inch with you.

This came today on engadget. Truthfully, I could do without all the fancy projection stuff, I'd much prefer a psion 5 size keyboard dock.

After playing MAME on my tv with the MHL cable for an hour and using a PS3 sixaxis controller over bluetooth, I loose about 15% battery life. Yes its plugged in otherwise it wont work The back got fairly warm after the first 5 mins.

Part of the problem with battery drain when using MHL is the inability to turn the GS2 screen off which is a pain. I was watching a movie on the TV and it was distracting to have the screen mirroring the TV.
If you want a netbook type thing then just get an original Galaxy Tab and a BT keyboard case like this one
This is what I use with my Tab and it works fine.

You could buy a Motorola Atrix ;-))

Phone to TV

Has anyone successfully connected the tmobile sgs2 to their tv and display their screen onto the tv? If so what materials do you need? I have the hdmi adapter (its like you plug one end into phone and then u plug the hidme cable into the other end and then that is connected to the tv) but i cant get it to work. Any help?

The MHL adapter needs power for it to work. I have the official Samsung adapter and it has a micro USB port on the side.

DITTO .... it has to have power, as the phone cannot supply what the HDMI needs ...

Thank you did not see that! Only problem now is to get the screen to cover it fully. Like when im in landscape mode on the tv its centered however when i make the phone go into portrait then it fully covers the tv

that sounds ass backwards ...... mine works correctly, in landscape it covers the whole screen ...

In my case, landscape fills my TV screen while portrait doesn't. If that's what's happening with you, I don't think there's an easy way to fix it. Through the adapter, the phone is only outputting a clone of whatever is on its main (built-in) display. It's not filling your TV screen because its a totally different aspect ratio.

MHL cable for a normal tv (not a HD one)

I have a normal tv with video in/out ports. Is it possible to connect SGS2 to a normal tv (not a HD one) using the MHL cable? I have seen a video on YouTube where someone has connected the Galaxy S with a cable in 3.5 mm audio port of the mobile to a tv set for a video output. Will this be possible with SG2?

AS far as i know this is not Possibile in Galaxy S2.
U can connect ur HD TV with HDMI Cable, but not standard TV with 3.5mm Jack.
i Dont know why SAMSUNG hasnt given this feature on GS2, it would be great if that feature was there.

Thanks for your reply. Can I connect to a non HD tv (normal tv) using HDMI/MHL cable?
Sent from my GT-I9100 using Tapatalk

i suppose yes.
U can connect to any TV that has a support for HDMI. {not sure though}

I don't think non HD tv's have support for HDMI. Only HD tv's have I suppose.

Really exist?...O_O thanks 4 info....i'm gonna search this...

MHL outputs a digital signal.
Standard TVs that do not have HDMI, with RCA jacks, take in an analog signal.
Something needs to convert the signal, so you need a Digital to Analog Converter, or DAC.

Probably because it would take more hardware to do so. Which increases production costs, and would have made the phone larger. There is a ton of stuff crammed into the phone as it is. It is basically a pocket sized computer.
If you can afford this phone, how can you not afford a TV that has an HDMI input?

I connected the MHL cable to a VISIO 720p television and it didn't work, I suppose that MHL sends 1080i/p signals only and your television must, at least, be able to handle this resolution and rescale it.

Not true. Any tv with an HDMI input will work. Doesn't have to be 1080i/p. Did you plug in a power source?

Huh. That's very weird. There shouldn't be an issue with plugging it into a 720p. In fact, I don't think the video output will even be 720p, let alone 1080i/p, unless the output is a video that is that resolution.

I think either the GS2 or the MHL adapter will upscale the image to 1080 regardless the resolution supported by the TV. But it's in fact weird because HD ready should support at least 1080i.

I have seen mini-USB to composite output cable (audio -left and right seperated- and S-Video output cables) for SGS2 on a shopping site but couldn't remember which one now. So it must be possible.

That could be. I can't test, as it works on I everything own... I don't own a TV or monitor that is less than 1080p.

I have my doubts about this - at least, the part that it was for an SGS2. MHL is a digital signal. S-Video is analog. So either the cable was REALLY expensive, or maybe they were trying to pass off a micro-USB to S-Video cable that it (falsely) works for the SGS2? Or it was actually for an SGS1?

The green screen on MHL/HDMI output happens, because of non HDCP compliant TV. All content that we get out of the USB to HDMI adapter is copy protected (HDCP).
I noticed this while I wanted to connect it to as HDMI to SDI converter. Also no capture card will accept this signal. Only HDCP TV and monitor will work.
I'm trying to figure out now how I can get 1080p desktop and gallery output.

MHL on normal TV
I read HDMI on "normal" TV (not HD) works if you use VGA adaptator.
A person on the forum i saw, gives a links to buy one and it was 40$ (For MHL adaptator + VGA adaptor that you need to input in the MHL)

Link? (I'm just curious)
My point above, is that the standard MHL adapter is only like $15. So it would be an additional cost to get ANOTHER adapter to plug that into a TV without an HDMI input. So $40 for that whole get-up would be more expensive. Less expensive than I thought it would be, but still more.
And based on what erzyk says in post 17, there is no guarantee this would work due to standard TVs not being HDCP compliant. But I'm just speculating.
Someone could buy this $40 mystery cable and test it out, I guess. It's just not gonna be me.

I'm agree with you it's very expensive (and i'm not going to buy this thing for 48$)
Here the link:

May be you can found it less expensive (i didn't search, i just saw a person that give the link with this expensive price).

HDMI Out and USB Hub at the same time?

Hi. I am trying to use my Note 2 as a desktop computer and I would like to achieve the following steps (at the same time):
-HDMI out with a correct screen resolution
-Use a 7 port Belkin USB Hub
I have tested each one separately. The hub works great using a Micro-USB adapter and the Samsung HML cable works but I am unable to get a correct screen resolution (image is always too big for the screen in every tv or monitor I have tried).
How can I get both things working correctly at the same time?
Many thanks

you should be able to correct the aspect ratio on whatever monitor you are using

My cheap Vizio 21.5" flat screen tv doesn't allow me to change the aspect ratio... but what about connecting HDMI and a USB hub both at the same time?

Note 10.1 (2014) as a VGA Presentation/Lecturing tool

I'm using the Samsung Galaxy Note 10.1 (2014 Edition) to give lectures (using the LectureNotes app to write during the lectures). I need to be able to connect it to typical VGA projector. Thought it might help others to know what accessories worked to do this:
Samsung MHL to HDMI adapter (model ET-H10FAUWE)
HDMI to VGA + Audio Converter (made by Neet, bought on amazon)
Optional: MoKo Samsung Galaxy Note 10.1 2014 Edition Case - Ultra Slim Lightweight Smart-shell Stand Case
The MHL to HDMI adapter is great. It did not come with a power supply but takes the same micro usb as the Note. It produces a beautiful image on an HDMI display (tested on both 720p and 1080p) and did not require any settings to make it work. In all cases it has worked without needing a power supply - presumably because it is drawing sufficient power from the hdmi port with the devices I have tried. If a power supply is connected it passes through to the Note (charging it if the power supply gives sufficient current). Connecting the adapter makes no impact on the speed of the device. Unfortunately none of our lecture theatres have hdmi connections.
The HDMI to VGA converter needs to be active (so needs power). The "Neet" one above had good reviews from people who had struggled to make this work with other devices. For me it worked straight out of the box. On a 1024 x 768 device it uses the full height of the display but not the full width: ileaves a narrow black band on the right. It is showing the full tablet image which is slightly distorted on the projector screen. The projector detected the display without problems.
For the case, I wanted one that works upside down in landscape mode so the return button is at the top left. This prevents accidentally closing the app while writing on the tablet. It also means the display cables run away from you. You need to switch off the auto brightness on the display because your hand will cover the front camera as you write and so the display will periodically dim - not that this makes any difference to the projector display but is just a distraction when writing.
The alternative method I tried to project the display was using a VNC server. I bought the VMLite VNC Server app. (The developer was very helpful and responsive.) By connecting this to a computer/laptop with a VGA connection, you can project the screen. However the VNC server significantly slowed down the tablet and made writing on the tablet less than pleasant. So I abandoned that in favour of the hardware method above.
Hope this helps someone - though your mileage may vary. (Sorry about the lack of links - not enough posts it seems so I had to strip them out).

you might also consider getting something like this, I tested it a few months back and it worked fine. Need external power , but besides that worked out of the box. Got recognized as a HDMI adapter.

Standard Micro USB charger, you can use the one that comes with your Note.

No support of the device for Galaxy Note 10.1 2014
Hello, are you sure that it works for this model of tablet? I tested this microUSB-VGA adapter with the Galaxy Note 10.1 ed 2014 and with 2 Sansung smartphones: Galaxy SIII, SIV, and no VGA neither audio signal is produced.

It worked for me with the one l linked. Tested on note 2014 and s3 both needed ext power

Personally I would eliminate the MHL to hdmi adapter and replace that with the netgear PTV 3000. That paired with the OP's hdmi to vga converter would result in a nice wireless solution so you don't have to be physically tied to the projector.

Have you actually tried the PTV3000 with the 2014 Note? Cause I have and it doesn't work properly, specially when streaming video. For a simple powerpoint presentation it's ok, but nothing more

I recently bought a Galaxy Note 10.1 2014 to use mostly as a business tool, so that I could run presentations and workshops in various locations. I did quite a lot of research about how to do this and finally selected the correct cable, an 11 pin MHL 2.0 micro USB to HDMI cable with a USB to power adapter. I was very disappointed to find out that I could not get the tablet to display on my Sony Bravia TV, but this setup works fine on other non Sony displays in the house such as the Panasonic one I have in my bedroom. Unfortunately this means I cannot reliably use my new tablet as intended in case I encounter a Sony TV or projector when I'm at a venue or on location. I wish I'd known this before I bought my tablet. A device such as a chromecast dongle isn't much use either since I don't always have a Wi-Fi connection.
I have noted that the OP is using an HDMI to VGA cable - does anybody know if this works on Sony displays or is the Sony/Samsung incompatibility universal?

The PTV3000 miracast device does not require separate WiFi connection after the initial setup. This and the Samsung AllShare Cast dongle worked well for me.
