The LG B4 is ranked in our best TV guide as the best value option for those looking for an OLED on a budget. The 2024 display packs LG's latest Alpha 8 AI processor, which uses AI to detect what you're watching to improve picture and sound quality. Thanks to its self-lit OLED pixels coupled with Dolby Vision and Dolby Atmos, you get a brilliant picture with bold colors and deep contrasts. You're also getting excellent gaming features, including four HDMI 2.1 ports and a 120Hz refresh rate, plus webOS 24 for easy access to all your favorite streaming channels.

While LG's 48-inch B4 briefly dropped to $499.99 once before, today's deal is still an excellent price for an OLED display. Thanks to spring sales from Walmart and Amazon, I've listed more of today's best March Madness TV deals further down the page, including record-low prices on 4K, QLED, and OLED displays.

March Madness TV deal: LG's B4 OLED

The LG B4 is one of the most affordable OLED TVs on the market, and Best Buy has the 48-inch model on sale for $549.99. That's an incredible price for an OLED display and only $50 more than the record-low price we briefly saw last week. Its self-lit OLED pixels and Dolby Vision enhance color and contrast beyond what the average backlit TV can do. Its built-in gaming features and 120Hz refresh rate also make it an unbeatable deal for gamers looking to upgrade for less.

You name it, the Samsung S90C does it all. It offers HDR OLED, which analyses each scene so you get rich and accurate Pantone-validated colors at all times. Its picture quality is great for movies, shows, and games, but its sound is also surprisingly good for TV speakers. The Samsung S90C also packs four HDMI 2.1 ports, which is perfect for game consoles. Today's deal from Walmart brings the 55-inch model down to $969 - an incredible price.

Here's the biggest discount yet on what we currently rate as the best budget TV you can buy. It's very rare to find a Mini-LED QLED display of this size for under $1,000, so it's one to snap up if you want some premium TV tech for a much lower price. It's an ideal buy if you like watching lots of TV shows and movies as they will look amazing with superior brightness, contrast and colors compared to standard displays. Gaming features are OK, too, though there are better TVs if that's your main interest – including the LG B4 below.

Amazon has LG's highly rated 65-inch C3 OLED TV on sale for an incredible price of $1,286.9. That's a whopping $1,200 discount and $100 more than the lowest-ever price. The stunning OLED display features a brilliant picture with bright colors and powerful contrast, thanks to LG's latest Alpha9 Gen6 chip. Plus, you're getting four HDMI 2.1 ports for the best gaming experience on next-gen consoles, a sleek, thin design, and an updated webOS experience.

The LG C4 OLED TV is one of the best TVs you can buy for its incredible picture quality and excellent performance. This well-sized 65-inch model is down to the record-low price we saw on Black Friday. The C4 features exceptional brightness, LG's latest Alpha 9 AI chip for improved performance, and impressive gaming features, including four HDMI 2.1 ports with 4K 120Hz, VRR, and ALLM support, and 144Hz certification from Nvidia. It's a versatile all-arounder that I recommend for watching shows, enjoying movies, and playing the latest games.

Here's a discount on a huge 75-inch model of Amazon's Fire TV Omni QLED Series. These displays are a big step up from the cheaper lineup of Fire TVs, with premium features such as a QLED display, HDR, Dolby Vision, local array dimming and HDMI 2.1 support to deliver a top-quality picture for all-around viewing and gaming. If display size is very important to you and you want an excellent level of quality for the price, then this is a great buy in the retailer's current sale.
