You can buy an LG OLED TV for only $549.99 for March Madness - yes, really

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.

The S90D OLED 4K TV is in the mid-range of Samsung's OLED TV series and delivers excellent quality despite foregoing some of the more premium features reserved for the Samsung S95D. Boasting bright and vivid colors, the S90D makes everything look amazing, while the 144Hz refresh rate and Samsung Gaming Hub give gamers everything they need. Today's deal from Amazon on the 42-inch model brings the price just under $1,000.

Amazon's Big Spring Sale has Samsung's 55-inch Q60D QLED TV for $547.99 - $100 cheaper than the record-low Black Friday price. The Q60D features 4K and Quantum HDR Smart technology with Motion Xcelerator, resulting in bright colors and realistic images. Its slim design also means it looks great in any living room.

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 an excellent big-screen QLED TV deal from Vizio, down to $448 for the 65-inch model. You're getting a gorgeous picture with HDR Dolby Vision coupled with a wide viewing angle for a premium experience. The Vizio display also features WiFi 6 for speedy streaming and gaming content.

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.

The best big-screen budget display in Amazon's Big Spring Sale is this Insignia 75-inch 4K Fire TV for just $349.99. The Insignia F50 TV features 4K HD resolution, DTS Studio Sound, smart capabilities with the Fire operating system, and a voice remote with hands-free Alexa, so you can use your voice to control your TV.

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.
