As well as giving you superb picture quality at Full HD 1080p resolution, Blu-ray discs also include Dolby Digital TrueHD or DTS HD Master Audio soundtracks, with next-gen object-based Dolby Atmos and DTS:X formats also available on certain titles.
If you want to go one step further, you can buy an Ultra HD Blu-ray player. They're capable of all the above but also boast the ability to play 4K Blu-ray discs. Here's our pick of the best Blu-ray players on the market.
The LG's nice to use and puts in a strong showing in the picture department, if only it sounded a bit better. We've seen it for under £50, which makes it a good option, but if you're going to spend any more, then you're better off going for our next option up, the Panasonic.
It's not cheap, but if you're going to be spending a serious amount on a 4K TV and 4K discs, then we think it's worth paying a premium for the best possible disc performance. And this Oppo delivers just that, thanks to impressive insight, rich colours and superb sound.
