Duplicating a Display over LAN

[AtrumEquus]

I'm trying to set up a system (as laid out in the diagram) where two different computers both (not at the same time) have the option to send the live feed of one of their monitors to the slave computer. The slave computer would then take the display feed over Ethernet and do whatever processing it needs, and then output it though HDMI to the TV. 

 

Every computer in the system has a dedicated GPU.

 

 

 

I know that steam big picture should be fine to work in this setup but I would like to be able to show the entire display not just when I'm playing a game.

Others have said Steam in-home Streaming should stream the desktop too. If not, NVidia's thing might.

VNC without control....?

 

Microsoft Remote Desktop without control...?

I think you want a KVM over IP, unless you have a monitor on each PC, then go with Microsoft Wireless Display Adapter.

This would be helpful to know. Lots more info needed for this project to work.

HDMI over CAT6 extender, if you really need to do this

[AtrumEquus]

What is the primary objective of this project?

Mostly just to use it as a main media center. I know steam could be use for games but one of the master computers is mine and then the other is my roommate's so we have to have the slave logged into the right steam account and then if the other person would want to stream they would have to re-log. Also if we want to watch a video in a browser it would be nice to just be able to alt-tab out of the game instead of having to then use chromecast or some different device to cast it.

this will not go through a switch.

How many HDMI inputs does the TV have? Why not simply plug an HDMI cable from each PC into a port in the TV?

 

Or you can take an HDMI switch for each PC, plug the GPU output into the switch, and have one output go to your monitor, and the other go to the TV. That way it'll either output to the monitor or the TV, depending on which selection you choose on the HDMI switch.

 

You could add a third HDMI switch at the TV itself, in case it only has one HDMI input (Which is unlikely. Most TV's have 2x or 3x HDMI inputs).

 

I'm just confused as to why you're trying to do this over Ethernet specifically? Is it because of cable run distances?

 

Alternatively, WIDI or MWD - Intel Wireless Display or Microsoft Wireless Display, are both options that would work. To get them to properly pair with each PC, you might need to purchase 2x Wireless Display adapters (Plugged into HDMI in the TV) - one for your PC, and another for your roommates PC. I'm just not sure whether a single Adapter can be easily paired to two different master computers.
