The Samsung UE65JU6400 supports Wi-Fi. Most of the other 4K and 8K TVs that were released in the last year also support Wi-Fi.
Alternative TVs which support Wi-Fi currently available which you might want to look at include cheaper TVs such as the LG 55UJ670 (£1,049), or the Samsung UE55KU6510U (£1,119.99).
We compared all the other TVs which also support Wi-Fi to this television and we think the Samsung HG49EE890 (£1,225.97) is also worth considering.
