Overview
Big-screen OLED is the reason to consider the Samsung QN77S85H, a 76.77-inch 4K One UI Tizen television with an NQ4 AI Gen2 processor. It lists 100% DCI-P3, HDR10+ Advanced and a 48–120 Hz range with VRR, ALLM and FreeSync Premium. Four HDMI 2.1 inputs support several gaming sources, though this size drops to two USB ports rather than the three on the 55-inch and 65-inch S85H. The 20W speaker system is light for such a large screen, making eARC useful for a soundbar. OLED's self-emissive pixels should aid black levels, but brightness and contrast figures remain unpublished. Dolby Vision is not supported. Buy it if you want a 77-inch OLED with four HDMI 2.1 ports; skip it if strong onboard audio or published HDR brightness matters.

Display Performance
Refresh Rate
48 Hz - 120 Hz
Supports high-frame-rate gaming and smoother motion in the QN77S85H.
Response Time
Not published
No pixel-response figure is published, so motion clarity should not be inferred from refresh rate alone as listed for QN77S85H.
Brightness
Not published
The source omits normal light output, preventing a meaningful bright-room comparison within the QN77S85H specification.
Contrast
Self-emissive OLED
Individual pixels can switch off for black, although the sheet gives no numerical contrast ratio on this QN77S85H model.
Colour Gamut

GPU Requirement4K up to 120 HzA current high-end GPU or console is needed for demanding games at the panel ceiling on this QN77S85H model.
HDR & Brightness Reality
QN77S85H uses self-emissive OLED pixels, lists 100 % DCI-P3 and accepts HDR10, HLG (Hybrid Log Gamma), HDR10+, HDR10+ Adaptive, HDR10+ Gaming, HDR10+ Advanced. Pixel-level light control should produce strong black levels, but typical and peak brightness are not published, so highlight intensity cannot be compared numerically. Samsung omits Dolby Vision, leaving HDR10+ as the dynamic format. The badge set is credible for OLED contrast, yet the missing brightness data remains an important limitation.

Frequently Asked Questions
01 How does the QN77S85H differ from the QN65S85H? +
It uses two USB ports rather than the three on the QN55S85H and QN65S85H. OLED, 4K resolution, 120 Hz and four HDMI 2.1 inputs remain the common foundation.
02 What does the QN77S85H OLED panel mean for dark scenes? +
Each pixel produces its own light and can switch off for black, avoiding a constantly lit LCD backlight. Brightness figures are missing, so highlight performance cannot be quantified.
03 Which gaming features matter on the QN77S85H? +
The sheet lists 48 Hz - 120 Hz, VRR, ALLM and AMD FreeSync Premium. Four HDMI 2.1 ports allow several modern consoles or PCs to stay connected.
04 Why is Dolby Vision absent from the QN77S85H HDR list? +
The published formats are HDR10, HLG (Hybrid Log Gamma), HDR10+, HDR10+ Adaptive, HDR10+ Gaming, HDR10+ Advanced. Dynamic metadata therefore relies on HDR10+ rather than Dolby Vision.
05 What is the largest practical weakness of the QN77S85H? +
Typical and peak brightness are not published, and the built-in audio is only 20W. A soundbar and independent brightness evidence may matter to demanding buyers.
