Along with Black Friday and Cyber Monday, Memorial Day is one of the best opportunities of the year to save on a TV, and it's all because of the timing. You see, big-box retailers like Best Buy are making one last push to move models from the previous year, which means some of the best and most popular sets are near their lowest price to date.I pored over pages of TV listings at Best Buy, and of all the deals available at the store's Memorial Day sale, this is my favorite: the 55-inch LG B5 OLED for $799. LG's entry-level OLED was already one of my most-recommended TVs heading into this week, but Best Buy's sale price has turned it into a no-brainer. (For more deals, check out our guide to the best Memorial Day TV sales).While it's picture isn't as bright or colorful as that of pricier OLED TVs, the B5 is still an OLED TV, which means you're getting all of the benefits that come with arguably the best display technology the industry has to offer.Instead of relying on a backlight, OLED TVs like the B5 leverage self-lit pixels. Not only does this allow for perfect black levels, but you also don't have to deal with that hazy, bluish light bloom you'll often see on LED TVs.The nature of OLED is also why the B5's relatively modest peak brightness goes a longer way. Its picture has better shadow detail than what you're likely to see on an LED-based TV with similar peak brightness, so highlights have a tendency to pop better.
