Can the deck get support for HDMI CEC
So then turn it on my TV, will switch HDMI input

Do you not understand electronics?

If I have two computers and I create a cable with HDMI on one end and Displayport on the other.

Do you understand standard committees? HDMI are full of busy bodies who make your life worse because they belief it will protect their cash flow.

Hence why there are HDMI to Display port cables you can buy. Because it just sends HDMI binary data over the wire..

Yea binary data... The conversion isn't passive. You need an active converter. It is easier to deal with displayport monitors than hdmi.

Binary is the base language of all computers, Steam Deck is a computer..

It transports the HDMI signal through USB-C to HDMI connection in our TVs using the Display port protocol. Like I've said you can send any data down any connector. Display port Protocol supports HDMI CEC, so if the Steam Deck sent the correct binary signal along port 13, the TV would be able to understand it..

Because, the Steam Deck is capable of sending binary code along a wire, because it is a computer..

You have two ways to transfer data

1) Analogue using Modulation
2) Digital using data bits (Binary Code)

Are we talking about the same HDMI? The cable has DRM built in into the standard.

HDMI isn't a dumb pipe. Most of us wish it is as dumb as you say it so we do not need to deal with handshake issues.

You literally don't have a clue what your talking about. The cables are just made of wire. They send an electrical signal on and off (Binary data)

It's the HDMI protocol (Software) that deals with HDCP, did you even read the article you are posting?

And I quote:

Before sending data, a transmitting device checks that the receiver is authorized to receive it. If so, the transmitter encrypts the data to prevent eavesdropping as it flows to the receiver.

That is the DEVICE transmitting the data asks the other DEVICE for confirmation. The cable has nothing to do with data transfer apart from sending binary from one device to the other..

DisplayPort not just a "connector", it's an entire protocol.

Do you not understand electronics?

If I have two computers and I create a cable with HDMI on one end and Displayport on the other.

I get one machine to send "Hello World" in binary code to the other machine, then on the other machine I get it to interpret the text through the graphics cards by reading the binary code.

I have written a protocol! A way of sending and receiving data between machines. DisplayPort is the connector on the wire.

What your getting confused with is the Software to interpret data through a Display Port connector is also called the Displayport Protocol. Basically a copy paste of code used by manufacturers to instantly provide support for display port devices.. But you can use the display port connector to send any type of data through it's headers. Aslong as you write the protocol yourself for both devices..

Hence why there are HDMI to Display port cables you can buy. Because it just sends HDMI binary data over the wire..

Believe me I have been through this with my work. We had to build a coin-operated juke box. The coin box would send Binary data through wires based on what coin was inserted. It didn't have a set connector, so I had to make my own internal USB connector, then write the code (Protocol) to interpret the binary into signals that could be used to add credit to the jukebox software and also send the correct binary data back to the coin box to give change..

If you had done something similar in electronics, you would realise what im saying is true..

are you some kind of a sleeper agent?
the deck uses USB-C port to transfer displayport protocol video and audio data to the dock. then the dock supports displayport MST for multimonitor use, and one of those displayport protocol monitors gets converted into HDMI protocol via an active adapter, and goes into an HDMI output port. the other monitor gets hooked up to a displayport port.

do you actually believe that HDMI and displayport video data is compatible? anyways, this is my last post, this is an ancient thread.

Yes they are compatible, they both send a DVI video signal via Binary code.

Hence why I have a Displayport to HDMI cable plugged into my PC.

And why you can also buy a direct USB-C to HDMI cable that runs using the Display port protocol that works fine with the Steam Deck.

Because HDMI just sends DVI video data, you can even get a HDMI to DVI cable.

Like I've said numerous times. It doesn't matter what the cable or connector is, as long as you send the correct data from one device to the other on the correct headers..

[Prezidentas]

all of those cables (with an exception to DVI-D to HDMI) have a converter chip at one end of the connector.

Your talking utter rubbish. Don't you know what a patch cable is? It's where one cable type, moves the pin headers around to match the plug on the other end..

You literally don't have a clue what your talking about, but your trying to argue.. I've proven my point numerous times.. Pointless trying to argue facts with people who won't listen.

DVI was the original cable,
HDMI adapted the same video format but added extra pins for audio.
Display Port adapted similar to the HDMI format and added extra pins both cables have phantom power and hot plug detection on the last 2 pins.

That's why when you have a Display port to HDMI cable, it can only go one way. Because Display Port can create HDMI by patching and removing un-needed header pins.

Then HDMI is backwards compatible with DVI but it loses the audio, because there is no header pins for LPCM audio in DVI..

Any modern Display port device has the ability to modulate the signal sent to the correct HDMI pins on the opposite end. The Display port to HDMI cables are passive, there is no converter built into them.. Like I said the device changes the signal, to send the correct data along the line, what is expected at the other end. The cables are just wires wrapped in plastic with a specific connector on the end..

Are you kidding me? Why does a cable standard need to prevent eavesdropping on the stuff I own? WTF? Do listen to yourself? Just send the damn data like a dumb pipe. If it doesn't work on the other end, whatever. Just play the stream. The fact that a device can refuse to play a valid stream is the reason why HDMI sucks.

You said a HDMI cable has HDCP and copy protection built into the cable. I proved you wrong. It's nothing to do with the cable. It's the devices that transmit and process the data, nothing to do with the cable..

HDMI data can be sent over display port, or any type of cable. The cable and connector are irrelevant, they are just plugs, plastic and wire.

You seem to assume, because the HDMI standard created a standardised plug called the HDMI plug for interconnecting devices that you can't use the HDMI protocol without that connector. Or there must be some special thing going on in the cable.. We'll you are wrong..

HDMI Cables are just wires to transmit signal, nothing more...

You can send HDMI signal over ethernet if you wish to transmit the signal long distances. The cables and connectors are irrelevant..

You must not understand standards at all. If every display expects it, the standard is no longer optional. HDCP isn't an optional feature.

Why are you defending DRM in the standard? Why the hell HDMI devices needs to prevent snooping? You havn't answer that question. HDMI is a pain in the ass because HDMI signals have DRM.

You don't understand how the underlying technology works. You are just guessing..
Google it, can't be bothered to argue with people who don't want to understand..

I did. You need HDCP to make your TV work. Without HDCP, your idea is worthless. HDMI suck because you can send valid signals to the TV you own and it doesn't work. Why expand a garbage connector? Are you a DRM shill? I want displayport or any other connector which doesnt have this stupid poison pill.

Do you hate consumers who want crap to work?

We were talking about how the underlying technology works, you are arguing about something completely different to what we are talking about. We were talking about electronics and how data is transmitted regardless of connector and your arguing about something completely different..

We did. It doesn't matter if you have DRM. DRM by nature is to break your valid use cases. DRM makes any idea terrible.
