Samsung has shown off a TV that can rotate into portrait orientation:
Samsung has unveiled a TV that switches from a horizontal, landscape-style orientation to vertical - so it can easily display smartphone content. The 43in device is called Sero and comes with an integrated easel-like stand upon which the screen pivots. It will go on sale in South Korea towards the end of May and cost 1.89m won (£1,250).
One TV analyst said it was an interesting concept - but might have limited applications. Sero will come with a microphone and Samsung's virtual assistant Bixby built in. It can also be set up to display photographs, a clock face or other images. Among the content users might choose to watch on it may be a new series of shows by Snapchat, designed for mobile consumption and set to be launched in May.

Basically every TV made today has VESA mounting holes on the back and you can mount it any way you like. I recommend the bold and dynamic diagonal orientation [xkcd.com].
Rather than a "vertical TV" this looks more like a regular TV with a very large rotating monitor stand attached to it. I guess most such stands are designed for desktop monitors so the novelty here is that the stand can support a 43" display.
