Question

Wirelessly connect tv to PC as second screen

Hi, I have a reasonably recent Samsung TV (UA55JU6400S) which is currently connected by HDMI cable to the PC, as a second (Well third) screen. I would like to do away with the cables and go wireless, can this be done?

Very important to note however I do NOT want to mirror my PC screen, It needs to be just like another detected display that I can drag windows to and from between the other screens, and control what side of my main screen it is on. It would also need to do audio (surround sound) otherwise I still need a cable for that defeating the purpose.

Any advice would be greatly appreciated, I do see there are devices around but it is not clear how it will actually operate, appears more like they mirror other devices to the TV...

There is no demand for such nuance

That’s why you would be designing a DIY solution and not buying something off the shelf.

Not sure how wireless surround even factors in since that also does work in the consumer environment currently. What sources would you be using and why the aversion to wires(?)

"control what side of my main screen it is on."

That's already a feature in Windows. I doubt any device would take on something that is already in Windows and Linux today.

As to the rest, why not Wireless HDMI?

Good call on the Wireless HDMI.

I see bottlenecks on the surround sound request, since that's typically going from input to AV receiver first, then out to HDTV. Anything wirelessly transmitted to the HDTV first will face obstacles going back out to the receiver, obviously.

Options? Maybe.

This one might be worth trying if it's what the OP has in mind, feature-wise:

PC (HDMI out) --> (HDMI in) 2x4 HDMI matrix switcher
2x4 HDMI matrix switcher (HDMI out) --> (HDMI in) HDTV #1
2x4 HDMI matrix switcher (HDMI out) --> (HDMI in) Wireless HDMI transmitter
Wireless HDMI receiver (HDMI out) --> (HDMI in) [AV receiver]
AV Receiver (HDMI out) --> (HDMI in) HDTV #2

*Omitting a receiver means no way for HDTV #2 to provide 5.1 surround other than what built in apps could provide. YMMV.

Let's also dismiss the TV as 5.1 over a nasty issue.

In reply to: I thought of options

All Samsungs I've tried and many other TVs block 5.1 or HD audio when the source is HDMI.

The idea that your HDTV can be a HD audio source is soundly trounced time and time again.

Here's the industry's stance on connections.

All sources to a receiver. Then the video goes on to the HDTV with an audio return over optical.

While folk push back against this setup, they are often the ones asking "Why doesn't it work?"
