Is there option to use chromcast as MHL cable? I mean sth like this: phone > USB OTG cable > standard usb-microusb cable - chromecast > TV

No not really...
MHL is just another name for Slimport. And it depends a lot on device support, many older devices have a true Mini HDMI port while newer models add slimport support to their USB port that can be plugged into a TV with the proper Slimport adapter.

i meant if phone already support MHL
I use Xperia Z1, its rooted and now it support screen mirroring but MHL is lagless, perfect for playing games especially if you have wireless game controller

Doesn't change the answer as far as the CCast is concerned....
the USB port is really only used for Powering the device under stock conditions and while I assume it might be possible to add MHL support to a Custom rom for Rooted units at this point none of that exists.
CCast is not really a display adapter it is a media device that is more like a browser on a stick.
Once booted the CCast can only communicate and get data via WiFi and thats where the lag comes from.
That said games written specifically for the CCast work differently as the game runs natively on the CCast and you control it via wireless which reduces the lag since very little bandwidth is needed and all the data intensive work is done on the device where WiFi and latency can't affect it.
But so far most games for CCast are very rudimentary I think your looking or Graphic intensive games that normally play on the mobile device...
I think the best you will from those types regarding CCast support is a Observer view where some can watch the action happening on the mobile device but where delay and lag doesn't affect the player.
You are better off and pretty much resigned to using cables for true live update.

I have two TVs, both with HDMI 1.4. I have read conflicting reports of power over HDMI with HDMI 1.4 being possible. Can anyone confirm this works, because I can't get it to?

my Vizio M551D which as 1.4a ports does not support power over hdmi.
As far as I know the only way to support power over HDMI is via like MHL, which the chromecast doesn't support.
I'm pretty sure any claim that said they were able to just power it via the hdmi port was BS
The Hdmi port does supply 50ma at 5vdc over pin 18. But from what I have seen on the chromecast pin 18 is not used or dead a small jumper wire going from this pin to a positive supply trace could in fact power the chromecast over hdmi as long as more then 50ma could be used. So this does not seem to be an option.
HDMI vs. MHL Power supply
Yes, HDMI has inherited some power supply requirements from DDC. It's 0,250W (5V * 50mA). This is unfortunately going in the wrong direction: From e.g. stick (if pin 18 is connected anyway, it's apparently not...) through HDMI to TV. This energy should be provided to power the internal EPROM of the TV. This intended for peripherals to read info about the HDMI-sink of the TV even when the TV is deeply sleeping. The spec even allows this 50mA to be reduced to 1mA when a session is initialized. Hence this is unuseable.
MHL has revered the power supply direction. This is now from TV to the Phone. This is inteded to power the phone. Unfotunately most TV sets at home don't have any or a proper MHL implementation available.
Hence a mass produced stick can't rely on that, and an additional USB power cable is mandatory.
Does this clarify the HDMI MHL power confusion a little?

Best topicson XDA! Fortunately with USB C HDMI will be outdated and replaced. Surprisingly I have not seen any TVs with USB C at this point.
Hi all.
I have used a MHL cable with my Xperia T ever since I got it.
With the original firmware, it would work fine with a basic HDMI cable and pretty much any TV with a HDMI input.
I've just been on holiday for 2 wks and discovered on day 2 that the latest firmware had a different MHL driver that requires HDCP. Apart from needing a newer spec cable, I also need a TV which supports HDCP - which the one at the holiday home didn't. My 5 year old was not impressed with not being able to watch any of his films for 2 wks!
So, anyone know of a way of getting back to a state where MHL is more user friendly? (Without having to rip back to earlier firmware.)
Seems mad Sony would force the feature since a lot of TVs don't support HDCP.
After no responses and my own continuing investigations I've solved my own problem and thought I'd post the outcome in case anybody else has a similar issue...
The MHL functionality works fine if both the TV and the cable are pre-HDCP. The problem I must've actually had was that the TV was HDCP compliant but my cable isn't HDMI v1.3+ (so didn't support HDCP.)
Basically, the solution to the problem I was experiencing is to use a HDCP compliant cable in all cases. That way it'll work on HDCP compliant and older spec TVs regardless. My confusion was caused by the message the phone prompted, which said the TV had to support HDCP - when in fact it did and the cable was the problem!
Let me rephrase just in case, I'd like to run emulators on my HTC One, play them with a Moga Controller via bluetooth, and watch them on my tv via an HDMI cable. But can an hdmi cable transfer everything shown on screen like running emulators? I've read that it only works for watching movies and internet browsing.
If this is all possible, what kind of hdmi cable and adapter would I need? I know the One doesn't support micro-hdmi, only mhl. Any suggestions?

Yes MHL is what you need. I use one made by PNY. Make sure you give the adapter power through the micro usb port. From my adapter I use a standard HDMI cable to the TV.
I believe it just mirrors everything on your phone, unless the app is programmed to do differently (like not showing playback controls on external screen). I play Real Racing 3 and use Netflix and play music with MHL.
A few things, though: MHL selects resolutions based on what you TV reports. If your TV does 1080p, then MHL uses that but at a lower refresh rate (I think it's 24Hz). If your TV only does 720p, then MHL will use that but at higher refresh rate (30? not sure). I never found a way to manually set it.
Then there's also a bit of lag. So if MHL chooses 1080p and lower refresh rate, it could become quite difficult to play fast action games.
I bought a type c to HDMI cable, hoping it would work with my TV Unfortunately it didnt, anyone know another way round this or if elephone are going to get a set up for this as I'm really wanting to watch the phone 4g access through my TV (not casting) as I've no phone line so no wifi, or access to one!!!!!???
Screen mirroring or Miracast will be your only option. You can also set up a hotspot if your smart tv is Wifi compatible. Alot of new phones have no MHL compatibility.
You can use chromecast with localcast app for media on your phone or stream off 4g using chromecast compatible apps without mirroring. It works with personal hotspot but you need a second phone to do the initial chromecast setup.
You can use a DisplayLink USB graphics adaptor and the DisplayLink app from the Google app store. It works for me.
I also can use a Dell D3100 docking station, for HDMI output, and keyboard _ mouse input.

What rom did you use and what DisplayLink USB graphics was that? I tried my own one, but it kind of didn't wanted to work.
Also, I'm really curious: Did the D3100 charge your phone while being used with stuff connected to the dock?

I use an elephone P9000 with standard ROM.
The dock does not charge the phone but the phone has wireless charging.

Currently the P9000 does not use the Dock audio output, nor the audio on my plugable USB3-HDMI-DVI adaptor.
I don't know if it used to to audio before the latest firmware.

I have also used this device with much success, with Dell Android Tablet, Windows laptops, Motorola Moto-G: http://plugable.com/products/usb3-hdmi-dvi/
It "works" with P9000 but currently is not passing audio over HDMI. I can't remember if I ever had that working on earlier firmware.
I'm thinking about using an Amazon Fire 7 inch tablet as a car radio dashboard install, but before I commit to buying one, I can't seem to find any conclusive answers on a few things.
Firstly, does the fire output USB audio so I can use a USB dac?
And if so, is it possible to use a Y split cable for USB audio and charging at the same time?
Any info would be greatly appreciated.

I can confidently say this Fire like most other Amazon devices will not support charging while the USB port is being used for any other function. Can't speak to USB audio out (suspect not) as most go with Bluetooth.

It does seem to be a difficult feature to find on Android tablets.
According to Wikipedia, it's a simple implementation of a USB otg cable that should allow charging on any usb otg device.
USB Otg Wiki
The major problem (presuming the cable does work and usb audio is possible) is that the kernel needs to be able to enable USB otg at the same time as charging.

Yep. The stock kernel on most consumer devices don't have robust OTG support as the most commonly used gizmo is a flash drive. I was able to get a OTG GPS receiver to work but it wasn't plug-n-play by any means. Charging didn't work in that context...although I didn't fiddle with it much.
I've been working on a kinda similar project, I just haven't had time. I'm trying to use my fire as an octoprint server, which is a program that monitors and controls 3d printers. The problem is that it requires usb to be connected to the printer, while also staying powered on. What I'm going to try is remove the battery, step down 12v from the printer to 3.7v and just hack it onto where the battery would connect to the pcb. I'm not sure what the different pins on the battery connector are though, so I'll have to test those. Otherwise, it should work.
