This allows your tv access to the internet, which it needs for the various smart tv apps.

The Wifi does replace a cable,

So.................. I DO NOT need a lead to allow a smart TV to access the internet*

Wasn't that what I originally asked ?

* but, if I wanted to view the TV screen to use my computer, then I DO need a lead - YES ?

thanks

It depends on the TV, not all are wireless and you may need a wireless adapter.

Some TVs allow screen mirroring so you can display the PC, Phone, tablet etc. using the home wifi network with no cable, or as is normally the case you can buy an adapter for that also.

Goto to a decent TV shop and see all the options at your price point.

You say 'connect', then you say WiFi which surely is a wireless signal ??

Yes, connect wirelessly - you tell the TV to connect, it looks for WiFi networks, it should find your router's WiFi network, and you enter the password, you are then 'connected' - not physically.

WiFi will NOT replace an HDMI cable.
What is the point of WiFi then ?

It's instead of an ETHERNET, or NETWORK cable, that carries 'computer data' - HDMI is a completely different type of cable, that carries video and audio data, and a completely different specification.

What IS WiFi, in the TV then. I thought to replace the cable. If I sit in Wetherspoons, the have free WiFi and my phone picks this up, ie wirelss, no lead.

Exactly - your phone receives data - not a TV picture. It receives information from the internet. Similarly, your TV would receive information from the internet. The best example of this would be BBC iPlayer, the catch up service. You can do this over WiFi, and broadband, but if you didn't have WiFi you would use an ethernet cable to connect the TV to the router.

Both I suppose. What is the difference

Computer connected = TV is just like a big monitor for your computer.

Spoke to someone at work, the have same make of TV - NO LEAD

Not much info here, but I guess they're just getting iPlayer etc over WiFi as I described.

So.................. I DO NOT need a lead to allow a smart TV to access the internet*

Correct - IF the TV has WiFi.

Wasn't that what I originally asked ?

No - this is what you said about Smart TVs and computers - so we had to pick it apart.

with a new smart tv (using wifi for comuter)

It depends.

WiFi is simply a wireless network, the ability for the TV to send and receive data. Connect to a router and this enables this data to be sent to and from the other devices connected to the same switch/ router. If the router is connected to the internet then the data can go to anything else connected to the internet.

What capabilities that creates depends on the applications that the sending and receiving device has. It absolutely can mean picture and sound can be sent from one device to another without the use of a cable if both devices have this capability set up and use the same protocols to do this.

So with my setup my TV can send what its displaying/ sound to my iPhone or iPad whilst I am connected to my network using their own app on my phone/ipad.

Unfortunately the TV doesnt have a built in app to allow me to do the reverse (ie send from my iPhone or MacBook) to the TV and so I bought an AppleTV that connects to the TV with HDMI and does allow me to mirror my desktop onto the TV and play sound through it. In theory there is no reason why this couldnt be built into the TV its just Samsung and Apple havent decided to make this happen.
