Samsung M70HB Mini LED 4K TV vs VIZIO Quantum 4K QLED VQD65X-10

Both are 65-inch 4K sets at 60 Hz, so the real split is backlight and platform. The Samsung M70HB uses Mini LED with precise dimming for deeper contrast and runs Tizen with Gaming Hub, Alexa and Google Assistant built in. The VIZIO VQD65X-10 is a full-array QLED with Dolby Vision and HDR10+, plus WiFi 6, and it costs less for similar size. Buy the Samsung for contrast, brightness and a smoother smart platform; buy the VIZIO if Dolby Vision and a lower outlay matter more than peak brightness. Owners rate both around 4.3 to 4.4, though the VIZIO has far fewer ratings.

• Choose the Samsung M70HB if you want Mini LED contrast, a bright picture and the fuller Tizen app and gaming setup.
• Choose the VIZIO VQD65X-10 if Dolby Vision and HDR10+ support plus WiFi 6 matter more to you than Mini LED brightness.
