[Android Q&A, Help & Troubleshooting] wlpywd:
1) PLEASE DON'T BAN ME, i did read and understand the warning as:

I am still posting here as, although the device i have is 4 androids ( EVO, EVO 3D, TRANSFORMER PRIME, ARCHOS A10|1T:8000), all with HDMI port (except the 3d, which has HDMI output through the USB port with a converter thingy), what I am posting about should, i would think, be an android-wide thing, not anything specific, especially for ICS and jellybean.

I know, and have read, all the specific device threads about HDMI input, but, as it would be near impossible to unit-specific code for HDMI communications, and as the HDMI standards state that they are functionally,and always have been, that HDMI is a 2-WAY communications protocol, then shouldn't an "HDMI input display" code be able to be written for Android as a whole, so there could be a stand-alone app for any android with an HDMI port to just 'sleep' android when an HDMI is connected with video-out signal being transmitted over it, and just default to a display?

Especially with ICS able to handle not only HDMI 2-way communication, but its' support for full HD displays (for example, TransformerPrime T701, and GoogleTVs), or even whatever the display is capable of?

So, shouldn't the app just be to read the port's input, if its HDMI signal, it can either 'suspend' or 'sleep' android and allow the device connected to simply pass display signal to the device?

If HDMI follows standards, which it must in order to even use the HDMI trademark, then any android which can dispay to HDMI out, by definition, MUST be able to receive HDMI communication from the other device. Anything over HDMIversion 1.5.

I have a working familiarity with HDMI output, but unfortunately, i've never had a chance to work with HDMI input coding, so I understand I could be way off.

so please, just tell me if I am mistaken, i can and will delete this thread or move it where you guys suggest, just please don't ban me for thinking this all the way through.

But my understanding of Android and HDMI is that anything that is capable of transmitting HDMI can be read by anything else that has HDMI (except china with its strick firewall) therefore, anything with an HDMI out and an HDMI to HDMI Mini or Micro cable should be able to connect to DVD players, computer graphic cards, XBOX. etc.

Why?

just to use as a display. I'm not sure about the archos, but i know the evo3D dual core and the ASUS ee transformer prime should have enough power to use as displays, probably with suspend, ANY HDMI signal and decode it and display it just as if were live. People would use to plug in dvd players, video game systems, etc while on the go.

So, with 2-way communication through HDMI, shouldn't we be able to make an app that would turn the android device into a small portable screen?

-----

Once again, i am thinking this is is an android-wide app or mod, which is why i am posting here. Please someone just tell me if it needs to be moved and not ban me for posting here, like the warning is saying.

I had snippets of various code pasted here that should be able to be pieced together into something working, but, as I don't really know what the lines mean or how to code it together, i'm gonna just end this here and see what everyone says.

Does GoogleTV handle the TV's various inputs through Android processing? could we just extract the control lines and turn it into an APP from that? or does GoogleTV only run when the TV is on a specific input channel, no android runs if switch input to Component or HDMI or others than the 'dedicated' android input selection?
