Need a home theater upgrade? Find major deals from brands like Samsung, LG and Sony with the best Memorial Day TV sales.

Amazon's cheapest Memorial Day TV deal is this 24-inch Insignia HD smart TV on sale for just $74.99. This is a fantastic deal if you're looking to add a smaller display to an extra bedroom. While the Insignia F20 Series lacks 4K resolution, you're getting the Fire TV experience built-in and an Alexa voice remote.

Memorial Day tends to be a huge day of deals for mattresses and home goods, but those are certainly not the only categories seeing major discounts. TVs of all shapes and sizes are also getting the deal treatment this holiday weekend, making it a particularly good time to upgrade your screen.
