Overview
Three HDMI 2.1 ports and 144 Hz motion headline the Samsung UN55M80H, a 54.6-inch Mini LED 4K smart TV. The 3840 x 2160 (4K) 10-bit Mini LED panel lists 100% DCI-P3 coverage, HDR10+ Gaming and a 48 Hz - 144 Hz range. VRR, FreeSync Premium, ALLM and three HDMI 2.1 inputs suit high-frame-rate play; DLG 240Hz is a processing mode rather than a higher native panel rate. One UI Tizen and the NQ4 AI Gen2 Processor cover streaming and upscaling, but brightness, contrast, speaker configuration and total audio output are unpublished. Buy it if you want a 54.6-inch Samsung Mini LED TV with 144 Hz VRR and three HDMI 2.1 ports; skip it if verified HDR luminance or a fully specified audio system is necessary.

Response Time
Not published
No pixel-response figure is published, so motion quality cannot be inferred from refresh rate alone.
Brightness
Not published
The sheet does not provide a usable luminance figure for comparing UN55M80H with brighter or dimmer rivals.
Contrast
Not published
No numeric contrast value is available, so black-level capability cannot be ranked from the sheet.

HDR & Brightness Reality
UN55M80H combines a 54.6-inch Mini LED panel, 10-bit colour, 100% DCI-P3 and HDR10, HDR10+, HDR10+ Adaptive, HDR10+ Gaming, HLG (Hybrid Log Gamma). HDR10+ Gaming and the 144 Hz platform are useful for compatible games, but the sheet gives no typical brightness, peak brightness, contrast or dimming-zone count. Those omissions matter more than the HDR badge when judging highlight impact and blooming. The published data supports broad colour and format compatibility, not a measured claim about premium HDR intensity.

Frequently Asked Questions
01 Which practical difference distinguishes UN55M80H from UN65M80H? +
UN55M80H uses a 54.6-inch panel, while UN65M80H uses 64.5-inch. The core M80H picture and smart-TV platform is closely related, so weight, dimensions, power use and VESA pattern become important differences.
02 What is the biggest unanswered picture question for UN55M80H? +
Typical brightness, peak brightness and contrast are not all published for UN55M80H. That prevents a reliable HDR-output comparison even when Mini LED, OLED or HDR10+ branding is listed.
03 How should the gaming refresh specification on UN55M80H be read? +
The native limit is 48 Hz - 144 Hz. VRR is listed, and AMD FreeSync Premium; processing modes such as DLG do not raise the native 4K refresh ceiling.
04 How many modern devices can UN55M80H keep connected? +
3 x HDMI 2.1 handle the main video sources, while 1 x USB 2.0 (Type-A; downstream) cover media or accessories. HDMI eARC provides the published route to external audio.
05 How much planning does UN55M80H need for placement? +
With the stand, UN55M80H is 1224.6 mm (millimeters) wide, 199 mm (millimeters) deep and 10.3 kg (kilograms). Wall mounting requires a 200 x 200 mm bracket rated for the panel weight.
