The short answer
For gaming, buy the TCL QM6K. Its native 144Hz panel beats the 60Hz panel Hisense lists for the 75U6N, and TCL's US store had the 75-inch at $849.99 on 16 Oct 2026. The 2024 Hisense U6N only makes sense if you find it clearly cheaper and you mostly watch TV and films.

When the QM6K wins
Gaming and newer hardware. A PlayStation 5 or Xbox Series X can send 120Hz, and only the QM6K can show it. TCL also states a zone count, while Hisense’s U6N page does not.
When the U6N could win
Price alone. The U6N is a 2024 model, so stores clear it out at discounts. If a 75-inch U6N costs well under the QM6K and you watch films and TV more than you game, the 60Hz panel matters less.
What would change the answer
- If you sit far from the screen, check the size first with the TV size calculator.
- To count your devices against the ports, use How many HDMI ports do I need?
- For a step up from the QM6K, see QM6K vs QM7L.
