When I test TVs, soundbars and projectors, my go-to source is 4K Blu-ray. That’s because, while 4K streaming can deliver good picture and audio quality, 4K Blu-ray has even better quality due to its higher bitrate (128Mbps to streaming’s 20Mbps average) and uncompressed soundtracks.
During my time at TechRadar testing the best TVs, I’ve had staple 4K discs that I always use as a reference. I wrote earlier this year about 4 awesome discs I’d recommend for evaluating your TV’s picture, and while I’d still recommend these (and I do still use some of them), it’s good to freshen things up every once in a while.
