I would avoid this company like the plague. Had an awful experience with them. I'm actually surprised UKHD have allowed them to be posted as a company to purchase from.
The idea was copied from the movie industry, most cinemas historically had a curved screen, though I doubt many people in the audience realised. The reason was that if you have a flat screen the light, coming from the projector at the back of the cinema, hits the centre of the screen at 90 degrees but hits the sides at a different angle, and this distorts the picture such that it looks bowed or curved. Also the edges were darker because they were further from the projector and the picture was impossible to focus properly, if it was in focus in the centre it was out at the sides, and vice-versa. So to counteract all these problems the screen was curved, side to side and top to bottom so that every part of it was the same distance from the projector. This corrected the distortion and made everything look flat to the audience and they saw a nice crisp even image. But of course all this is totally irrelevant to TV’s because the image isn’t projected; they produce their own light from within.
The screen doesn’t look straight ;)
I wouldn't be happy with the damage on this TV to be honest, even if the price is good. Not worth it. I will weigh in that I have this in a 55 inch curved model and have no issue with viewing angles! Yes, sitting dead centre is best, like on any screen, but we have a large L shaped sofa and wherever you sit on it the view is just fine. You'd have to be looking totally from the side to have a bad view, but that would be the same as a flat TV. The only thing I miss about my old flat screen is that you can't swivel this, so I can't angle it to watch from the kitchen while cooking. But that's a worthy sacrifice for a badass looking curved screen.
