So, you missed all of the weekend’s best Presidents’ Day sales and you’ve got nothing to show for it. Well, if you’re in the market for a new 4K TV, I’ve got some good news: Best Buy has extended a deep discount on one of the most affordable Mini-LED TVs you can buy.

Today, you can land the 55-inch TCL QM5K for just $379 at Best Buy. That’s $320 off its original price, and easily one of the most affordable ways to bring Mini-LED backlighting into your home. (For more deals, check out our guide to this week's best TV deals).

The QM5K is a Best Buy-exclusive model, so you won’t find it anywhere else. If all you’re looking for is an affordable smart TV that doesn’t scrape the bottom of the barrel, the QM5K is a good pick — especially at this price.

The QM5K's best feature is its hardware. It's not easy to find Mini-LED backlighting at this price point, and it truly makes a difference.

The QM5K makes use of a more modest array of Mini-LEDs when compared to higher-end Mini-LED TVs (like the TCL QM7K and the TCL QM8K). Still, it's better to have Mini-LEDs than a garden-variety, edge-lit LED display, as it typically results in better contrast and higher brightness.

If you're hoping to lean on your next TV's built-in smart features for all of your streaming needs, the QM5K is a reliable pick. It arrives with the Google TV software suite right out of the box, which is one of my preferred smart platforms in 2026 due to its relatively straightforward interface and vast library of downloadable apps.

The QM5K isn't going to blow you away with its performance, but it's a much better option than most 55-inch LED TVs in its price range based on its Mini-LED backlighting alone. It's an especially good pick for people who are upgrading to 4K for the first time.
