The TCL QM6K is the strongest source-backed pick for a 55-inch smart TV under $500: TechRadar named it its best model in this price category, and reported a $499.99 Best Buy sale price. That price is a dated snapshot, not a standing offer. The Hisense U65QF is a worthwhile alternative if you value brightness and gaming connections, but Tom’s Guide flags tradeoffs in fast-action handling, light bloom, viewing angles and its Fire TV interface.
Best 55-inch smart TV under $500: TCL QM6K
TechRadar’s 55-inch 4K TV guide, updated August 14, 2026, names the 55-inch TCL QM6K its best TV under $500. It combines a Mini-LED screen, Google TV and a listed 144Hz refresh rate. TechRadar reports four HDMI 2.1 ports and support for Dolby Vision IQ, HDR10+, HDR10 and HLG.

When the Hisense U65QF is a better fit
The 55-inch Hisense U65QF is the alternative to consider if you want a 144Hz panel and HDMI 2.1 connections while staying below the $500 ceiling. Tom’s Guide lists two HDMI 2.1 ports, two HDMI 2.0 ports, one USB 2.0 port and one USB 3.0 port. It also lists 4K resolution (3,840 × 2,160), Amazon Fire TV, and support for Dolby Vision, HDR10, HDR10+ and HLG.
Tom’s Guide reports strong brightness and color, but also notes issues with some fast-moving scenes, light bloom and viewing angles, along with an uninspiring Fire TV interface. Those are the guide’s review findings, not independent test results here. Its best TVs under $500 guide provides the recommendation and model details.

What should you look for in a 55-inch TV?
Match brightness and screen technology to the room
A bright room puts more pressure on a TV’s ability to produce a visible picture. The TCL’s reported moderate-daylight performance offers a useful review reference, but room brightness, window placement and viewing habits differ. Don’t assume a screen technology or a peak-brightness figure alone guarantees a good result in your home.
Check HDR support and review findings together
Both models list Dolby Vision, HDR10, HDR10+ and HLG support, though the TCL lists Dolby Vision IQ specifically. Format support tells you what a TV can accept; it does not by itself establish how impressive HDR will look. Consider the reviewers’ picture-quality observations as well as the specifications.

Count the ports you will actually use
Both TVs list a 144Hz refresh rate and HDMI 2.1 ports, features relevant to gaming. The QM6K has four HDMI 2.1 ports; the U65QF has two, alongside two HDMI 2.0 ports. Count the devices you plan to connect—such as a console, receiver or streaming device—and check whether the available ports suit your setup.
Choose the smart-TV interface you prefer
The QM6K uses Google TV, while the U65QF uses Fire TV. Since the platform affects the built-in smart-TV experience, include it in the decision rather than choosing on panel features alone. The cited U65QF review specifically criticizes its interface; the available source details do not establish an equivalent interface drawback for the TCL.

- Set a delivered-price ceiling. Compare the checkout total, including any delivery charge, with your $500 budget. A sale price reported earlier is not proof that the offer remains available.
- Confirm the exact 55-inch model. Check the model name and any suffix on the retailer listing; similarly named or differently sized versions may have different specifications.
- Check current stock and return terms. Read the retailer’s current return policy and any conditions that apply to the specific listing before ordering.
- Recheck the connections and platform. Make sure the TV has enough of the ports you need and that you are comfortable with its smart-TV system.
