Then noted that the TV was showing up in Wireless Devices but local
wireless (this PC) was turned off.
[Noting that TV and PC are connected to the internal network via
Ethernet but that would be too easy if it worked, yeah?]

Turned on wireless but no change.
Single or double click on the device name seems to produce some moving
blue dots right at the top of the scren, but nothing else.

I expect that this is yet another case of magic pixie dust which will
seem trivial once working.
Still, a very long HDMI cable seems to be an easier option at the
moment.

Or a shorter cable and a wireless mouse and keyboard.

Technology, eh?

Oh, the TV has the latest software, recently updated.

Oh, dear!

Further checking and the LG display showing up in the list of "wireless devices" was the one connected to this PC via a cable.

Once I'd turned on WiFi on the TV alongside the Ethernet then it all
sprang to life.

Strangely the TV didn't warn me that there was no wireless turned on so a wireless connection wouldn't work.

Anyway, I can now collaborate over things using the big TV whilst sitting
on the sofa across the room.

Just further chatter.

With the laptop plugged into the big 4K LG monitor I can get higher
resolutions (but not, I think, 4K) on the TV.

With the laptop not plugged into anything but using wireless to connect to
the TV I can't get anything above Full HD which is the native resolution
of the laptop screen.

I'm not sure if the Thunderbolt connection to the Dell hub is affecting
things, but otherwise I would have thought that if the laptop can support
a 4K monitor directly connected and also a 4K TV remotely connected then
it should be able to support a 4K TV when not wired to anything.

Oh, and when wired to the big monitor I can close the laptop lid and just
use the big monitor.

If I'm using Miracast (or similar) if I close the laptop lid the whole
thing shuts off.

Nothing is easy, is it?

Cheers

Windows 10 has its rules on enabling and disabling output, reassigning
'main' screens and auto detecting the presence monitors over DCC.
Sometimes I'd like to over-ride that. No dice.

What's the lag like and can you see any compression artefacts?

WiDi and/or Miracast aren't worth the effort of trying to get them to work, too finicky during setup, colours are horrid, jitter and judder mean you won't be able to bear watching it, even if it "works"

Buy a chromecast/firestick/whatever.

A bit laggy but I'm not trying to view video at the moment.

First use case is to display maps on the big screen to aid holiday
planning.

I haven't checked the bandwidth from the TV location but it won't get much better than the upstairs office which is right next to the wireless router.

Ta.

Have two Firesticks but so far never seen the need on the main
installation as it is networked to the hilt and also has Apps on the TV
and the VM box.
