Samsung S90H 77" OLED (QE77S90H) review

Full review

The S90H is Samsung's mid-range OLED for 2026, sitting below the S95H and S99H. Its stand-out feature for UK homes is the Glare Free screen finish, which is designed to diffuse window and lamp reflections far better than a standard glossy OLED. If your 77-inch TV will face a window, that alone may make it the better pick.

Samsung's spec sheet, as listed by Euronics Ireland, gives 4K at up to 165Hz on all four HDMI inputs plus eARC, so it matches LG's C6 for gaming connectivity. The panel is 100Hz native with VRR up to 165Hz.

The main catch is HDR: Samsung supports HDR10+ (including the new HDR10+ Advanced) but still not Dolby Vision. Content in Dolby Vision plays in standard HDR10 instead, which still looks good but lacks the scene-by-scene tuning.

Samsung may use different OLED panel types across the S90H range depending on size, so two S90Hs of different sizes may not look identical. Tizen is fast and comes with a seven-year upgrade promise, though the home screen promotes Samsung TV Plus heavily.
