Samsung M70H 65" 4K Ultra HD Mini LED HDR Vision AI Smart TV vs S90H 77" 4K Ultra HD OLED HDR Vision AI Smart TV — Comparison

The Samsung UE65M70H, known as the M70H, is a 65-inch Mini LED TV at £799. The Samsung QE77S90H, known as the S90H, is a 77-inch OLED TV, 12 inches larger, with an anti-reflective panel that the M70H lacks. The price listed for the S90H is not reliable, so no price comparison is made here and you should check the current figure before deciding.

On paper the S90H has a 165Hz refresh rate against 50Hz for the M70H, four HDMI 2.1 ports against three HDMI 2.0 ports, and Dolby Atmos sound support, which the M70H does not list. Both support variable refresh rate, auto low latency mode, Freeview HD and built-in Wi-Fi, and neither has Dolby Vision or a BBC iPlayer app. The S90H is rated class G for energy against class F for the M70H, with a higher listed HDR energy figure of 327kWh per 1000 hours against 149.

The M70H suits a living room or bedroom where a solid picture and sound at £799 matter most. Buyers praise its picture and sound for the money, its slim, light design and its easy set-up. They also report poor terrestrial reception for aerial users, a wall mount that blocks two HDMI ports, and a missing BBC iPlayer app at launch. The S90H suits a larger room where OLED picture quality matters. Its buyers praise the picture and sound, and one found the matt coating cut reflections well when used as a monitor, though strong reflections can add a purple tinge.

Bottom line: choose the Samsung UE65M70H if you want a 65-inch Mini LED TV at £799 for everyday viewing; choose the Samsung QE77S90H if you want a 77-inch OLED with a 165Hz panel, Dolby Atmos and an anti-reflective screen.
