Overview
Mini LED and 144 Hz define the Samsung UN75M80H, a 74.5-inch 4K smart TV running One UI Tizen. Its Mini LED panel lists 4K resolution, 10 bits colour and 100 % DCI-P3, with HDR10+ Adaptive and HDR10+ Gaming. Gaming reaches 48–144 Hz with VRR, ALLM and three HDMI 2.1 inputs, a clear step above Samsung's 60 Hz Q6F. One UI Tizen and the NQ4 AI Gen2 Processor cover apps and upscaling, but speaker power, brightness, contrast and dimming-zone counts are not published. The set is 1668 mm wide and weighs 22.5 kg with its stand, so delivery and furniture checks matter. Buy it if you want a large Samsung Mini LED 4K TV with 144 Hz gaming; skip it if Dolby Vision or published brightness data is essential.

HDR & Brightness Reality
UN75M80H combines Mini LED, 10 bits colour and 100 % DCI-P3 with HDR10, HDR10+, HDR10+ Adaptive, HDR10+ Gaming, HLG. That gives the set a credible HDR format and colour foundation, but the sheet publishes no typical brightness, peak brightness, contrast or local-dimming zone count. Those missing figures prevent a reliable judgement of highlight intensity and blooming control. Dolby Vision is absent, so HDR value depends on HDR10+ material and the unquantified Mini LED hardware.
