We love a good tv screen, but we don't get hung up on them.
They are still just a big tv
In my opinion Loewe offer the best pictures and are gorgeous sets with a style that looks great in any home, however a real cinema needs a projector and screen to give that immersive experience.
The single most expensive item is the projector itself, and it so important to get that right.
We currently recommend Epson, and Sony to cover a wide range of prices and capabilities.
Full cinema installs range from around £ 7000 to £ 70,000 so hopefully there is something in there for your budget.
Here are a few pointers:
Tescene and Epson both do really cheap projectors from a few hundred, but they are really for data and presentations.
Something good starts around £2000. The Epson 7400 at £ 2199 is particularly good
Sony are the most experienced at TRUE 4K projectors
With three excellent models the pricing is very simple, £ 4999, £ 9999, £ 14,999
Surprise surprise the more you pay the better it gets, better colour, brighter, smoother movement
This sets the standard for your system so choose this very carefully
