Been on the lookout over Prime Day for some 4K Blu-ray deals? I've been searching through them and have picked offers on discs I've tested as part of our Blu-ray Bounty feature, so I know these discs are worth your time. • View the full Amazon Prime Day saleAmazon Prime Day can be a great time for 4K Blu-ray sales and this time is no different. Some highlight discs I've found include Sinners, which is both a picture and audio showcase, especially for Dolby Atmos. There's also Se7en, a fantastic-looking movie with plenty of richly detailed scenes that show off 4K's clarity, which look great on the best OLED TVs. Sunset Boulevard looks excellent on 4K and shows what new life it can bring to older movies. My final highlight here is F1. If you're looking for a disc to show off your sound system, be that one of the best soundbars or a full surround setup, this is an awesome disc.
