Because tv has hdmi input and laptop has hdmi output. You are trying to output hdmi from your phone which should go into the input. Since your laptop is not an input you cannot and will not see anything.

Is there any adapters that are made to lets say Hdmi to usb? I've seen one for hdmi to svideo. But most laptops don't have that either.

Are you just trying to use the laptop screen as a TV for the phone?

Yeah. Pointless I know I mean its a laptop. But my computer has hdmi inputs. Well the monitor does.

If your monitor has hdmi input then just plug in the hdmi cable into it.

so what you are saying is it shows nothing either on my phone or my laptop after connecting the HDMI cable ?
actually what I need to do is to run webtop on my computer.so i need to root the phone.before rooting i need to know all the things are working perfectly .
After rooting would it show those options in my phone and the laptop ?

@zeealot, you cant connect your phone to any laptop via hdmi... the hdmi port on your phone is for output so as the hdmi port on most laptops so therefore you cant connect output-to-output
if you want to display/output your phone on a bigger screen, you can only connect to a tv or an external monitor that has hdmi input port... also, rooting your phone doesnt have anything to do with it... I hope I explained that clearly to you

now, that sucks ...

You could try using a HDMI capture device like this one:

but it is probably expensive.

$200 its professional grade used for way more then what your wanting it for. You can actually hook up your xbox or ps3 to your laptop with this and record the game play as your playing it.

Why don't you just buy the laptop and be done with it? You obviously have no clue about how HDMI works, and I wouldn't trust you trying to perform mods to your phone because I know you'll end up here whinging you bricked your phone.
Sigh.

you CAN NOT connect it to a laptop BUT if you're referring to an external display with hdmi input (monitor/tv) you can still use webtop without a dock... just search the forum for hdmi mirroring

Is there any way to make the HDMI output of the laptop to HDMI input ?like by using a converter ?

No. It's not possible. Period.
Use your TV, or get the lap dock, there is physically no way to make your laptop show the webtop off of your phone without an extra tuner card (hdmi are expensive, and not worth it).
Btw, google is your friend.

I think yhe2x had made it very clear already! Buy a new LapTop with HDMI "IN" port.

Even though I think dingdong a laptop with any form of input would be nearly impossible. Laptops just aren't something people expect, or use, as a secondary display.
Plain and simple... There is no way to connect your phone to the laptop and use webtop mode. TV, yes. HDMI computer monitor, yes. Laptop, no.

[Q] Nexus 7 as a monitor

I have purchased a Rasberry Pi and would like to use my Nexus 7 as the monitor.
The Rpi has hdmi and video cable (yellow rca) as output mediums.
The nexus 7 only has micro USB input
Is there an app (such as DSLR) that would provide this facility.
Or any other way of turning my Nexus 7 into a monitor ?
Thanks for your help

dont thing so..usb is no hdmi..but you can use some remote app to have it over wifi

I'm not sure the specifics, but I imagine if you wanted to do something like this you would need a server side program running on the Pi itself, with an app to attach to it. You could possibly run a vnc server on the pi and have it start the X-Session when someone uses VNC, then you would be able to to access with a vnc viewer on your Nexus 7, of course to do this you'd have to be able to set it up initially. This may also lead to lag as it'll be over a wifi connection.
As far as I know there's no way to do a wired connection, unless maybe using some sort of USB video input with an OTG cable. Would possibly require a bit of hacking on the Nexus side of things.

Old HTC Evo 4G needs new life

I've been thinking about what I could do with an old smartphone. I've done a lot of googling and see most people use their device for internet phone calls, media, wifi only, etc... but I want to do something more.
it has so many sensors and an hdmi port that i think should be made useful. Looking for some suggestions.

If it has hdmi, hook it up to your tv as a media player- play movies from it etc. get a wireless usb/keyboard mouse and connect it to your phone with a usb otg adapter. Connect to your home pc with ES File Explorer.

I mean, what could I do if I took the phone apart and utilized the internals for another project?

[Q] XBOX360 Controller on Nexus 4 via OTG?

Hi all, i have just installed the mod for OTG, it work great and i can mount any usb storage =) But now i want to use the original XBOX360 gamepade, the same i use for PC, on my nexus 4. If i plug it in the OTG cable the light in the middle of the gamepad start blinking but nothing happen, it doesn't work =( What i should do?

Is it a wired or wireless controller?
I believe goog added native support for the wired one around HC 3.1/3.2,
but they never added support for wireless ones.

He said its the wired one.
I have no idea if it works. But maybe you can find something in settings/language&input ?
I never got my 360 controllers to work even under Windows so I wouldn't expect too much, haha.

Unless you're running win95, all you need are the drivers.
There's downloadable drivers for xp/vista/7, it's pre-included in 8/8.1.
It might be pre-included in 7, but it's been years since i used it.
Android does include the key mapping profiles for 360 controllers, there shouldnt be any additional settings options for it. But i've never had a wired controller to test it with.
It should automagically map it so that it follows the android default mapping for controllers.

Nexus 4 does not support USB OTG without a kernel hack and external power for the device. Also, the drivers are preinstalled on windows 8, previous OSs need an installer

I dunno how I missed that. It should work then... The controller might need its own power though

Yea I know apparently they are supposed to work under windows. Never did for me though (xp, 7) no matter which drivers and methods I used.

Music in car through usb

Does anyone know how I would be able to play music in my car through usb? I am currently using tune link which uses Bluetooth and 3.5 jack. The issue I have, is that I have to change the song using my phone rather than the control buttons on my steering wheel. Sounds dumb, but I hate having to pick up my phone and navigate to screen to change the song.

Try using an OTG, it enables the phone to be used as a typical computer usb port.

I will try that.

Have 100% the same problem. Did anybody find the solution? My old Xperia Acr connected like a common flash card and worked fine. Now I have to use AUX and this is not so comfortable =/

Why do you use a cable AND Bluetooth ? Does you car have AD2P ? If it has you should be able to play music through your phones BT and have the steerring controls . I have a Kenwood head unit DNX 9140 and when i pair my phone to it, i can play music and still keep steering controls over BT

The music out via USB was removed on the s5...was present on the s4.

Not true. There is a lot of misinformation promulgated on the subject. Music out on USB works fine on my S5 just as it did on the S4, S3, S2 and S1..
But that isn't to say that Samsung, Google or (especially) the automotive audio equipment cartel make much effort towards standardized interoperability. It's frankly a mess, a hodge podge of half ass implementations and proprietary protocols that usually don't play nicely together. It can be made to work with carefully chosen components or creative approaches. But randomly connecting components from two different vendors typically fails.
While Samsung and Google could be characterized as only having made a minimal effort to provide standardized USB support.. that is still leagues ahead of what most automotive audio vendors have done. Not to mention that it's routine to find inaccurate details, if not outright lies of what automotive component X will supposedly interconnect with. I sometimes wonder if their marketing departments even bother to collate real facts on the subject before they write their copy.
It's not too hard to find decent DACs and headphone amps that will accept USB audio out from the S5, but I frankly gave up trying to figure out what would or wouldn't work on the automotive end. I ended up going with a brute force approach and installed a SBC (miniature PC) in my car. Having a full PC as a middleman, means that there is a vast array of powerful software (and hardware) that can slice, dice and format the control stream to whatever is needed by the auto head unit. But it's hardly a simple or off the shelf solution.
The OP can probably find a working solution if he searches hard enough. The S5 has USB audio out, although making it work with some car decks requires a combination of root, custom kernels (proper USB host support) and audio apps. An app like USB Audio Player, in conjunction with a kernel that has proper USB host support will satisfy many auto decks.
Hopefully Android L will give us better USB support. But it also depends on how sane your automotive equipment vendor was when they designed your car deck too.

The problem is that since 4.1.2,USB Mass Storage was removed.
Most, if not all, radios, media players, etc don't support the MTP protocol. They require a mass storage device, and do not support a media device.

MTP is a newer and much more capable protocol. The problem in your example is that radio, etc vendors are stuck in the past and not adopting newer standards.
MSC (mass storage) has many serious drawbacks that are overcome by the newer transactional protocol. MTP was standardized six years ago, which is just short of forever in consumer electronics. So one has to wonder why the radio vendors continue to drag their heels and can't get with the program.
It's like blaming Android for having moved to flash memory.. and refusing to go along. Expecting everyone to continue using cassette tapes instead. Yes that would be one way to maintain compatibity. But it doesn't make a lot of objective sense.

Yes, and for activation Mass Storage root is required ...

Guys, but what about using USB analog audio input? I remember I did something like that with Galaxy S II - from 5 mini USB pins one was used to sense what phone is connecting to - for ex if it is a car dock, desk dock or... should it enable analog audio output on USB data pins.
Unfortunately I no longer have dock I made back then, anyone knows if that might work with S5?
