Samsung M70H 65" 4K Ultra HD Mini LED HDR Vision AI Smart TV vs S90H 65" 4K Ultra HD OLED HDR Vision AI Smart TV — Comparison

The Samsung M70H and the Samsung S90H are both 65-inch 4K smart TVs with Tizen, built-in Wi-Fi, Bluetooth and variable refresh rate, so the real difference is the panel. The M70H is a Mini LED set listed at £799, while the S90H is an OLED with a considerably more advanced specification.

On paper the OLED is the more capable set. It has a 165Hz refresh rate against 50Hz, an anti-reflective panel, four HDMI 2.1 ports against three HDMI 2.0 ports, Dolby Atmos sound and nVidia Sync, none of which the M70H offers. Its energy use is mixed: it is rated G at 198kWh per 1000 hours of HDR viewing against 149kWh for the M70H, yet it uses less on standard content at 85kWh against 102kWh. Neither set offers Dolby Vision or a BBC iPlayer app, and both carry a one-year guarantee.

Buyers of the M70H praise the picture and sound for the money, the quick set-up and the slim, light build. The complaints are specific: one owner found that terrestrial channels would not retune, and the same buyer noted that wall mounting blocks two of the HDMI ports. Another found the picture basic compared with expectations, so set your expectations accordingly. The S90H has drawn mixed feedback, with one buyer disappointed that BBC iPlayer is missing from the model.

Bottom line: choose the M70H if you want a 65-inch set for everyday viewing at £799, and choose the S90H if you want an OLED panel, a 165Hz refresh rate and HDMI 2.1 ports for gaming.
