Samsung QN85Q70DAF 85"

Manufacturer: Samsung

The Samsung QN85Q70DAF is an 84.5-inch QLED television built around a 4K LCD panel with LED backlighting, designed to fill large living spaces with a 3840 x 2160 pixel image. It carries built-in smart TV functionality along with AMD FreeSync Premium adaptive sync support, making it a versatile screen for both broadcast viewing and console gaming. Voice command support, AirPlay, Google Assistant, and Alexa compatibility are all included, and the rechargeable remote adds a small but practical convenience to daily use.

The display renders at 52 ppi with a 10-bit color depth capable of reproducing around 1.07 billion colors, and it supports HDR10, HDR10+, and HLG, though Dolby Vision is not available. The panel offers 178-degree horizontal and vertical viewing angles alongside an anti-reflection coating and an ambient light sensor. Connectivity is handled by four HDMI 2.1 ports with ARC and eARC support, two USB ports, an RJ45 jack, and Wi-Fi 5, while audio is managed by a stereo speaker system rated at 2 x 10W with Dolby Audio and Dolby Digital Plus support. DVB-T, DVB-T2, DVB-C, DVB-S, and DVB-S2 tuner standards are included, and USB recording is supported.

Pros
  • The 84.5-inch QLED panel runs at 120Hz with AMD FreeSync Premium support, making it responsive for both fast-moving content and console gaming
  • Four HDMI 2.1 ports provide ample connections for multiple high-bandwidth devices simultaneously, with both ARC and eARC available for external audio equipment
  • HDR10+ and HLG support alongside a 10-bit panel capable of 1.07 billion colors allows for a broad range of HDR content compatibility
  • The 178-degree horizontal and vertical viewing angles combined with an anti-reflection coating make the screen usable from a wide range of seating positions
  • Smart TV features include voice commands, Google Assistant and Alexa compatibility, AirPlay, USB recording, a built-in browser, and a rechargeable remote, covering most day-to-day smart use cases
  • VESA mount support gives flexibility for wall installation alongside standard stand use
Cons
  • Dolby Vision is not supported, which excludes a widely used HDR format found on streaming platforms and Blu-ray content
  • The built-in stereo speaker system is rated at only 2 x 10W with no subwoofer, and Dolby Atmos, DTS:X, and DTS-HD are all absent, limiting the onboard audio experience for a screen of this size
  • Wi-Fi is limited to Wi-Fi 5, with no Wi-Fi 6 support, which may be a limitation in environments with newer network infrastructure
  • There is no 3.5 mm headset jack, so connecting wired headphones directly to the TV is not possible
  • Chromecast is not built in, which may inconvenience users who rely on Google Cast for content streaming
  • Apple HomeKit and Siri are not supported, limiting integration for users within the Apple ecosystem
Who is this for?

The Samsung QN85Q70DAF is well-matched to users setting up a large-screen entertainment space where multi-device connectivity is a priority, given its four HDMI 2.1 ports and broad smart platform support including Google Assistant, Alexa, and AirPlay. The 120Hz refresh rate and AMD FreeSync Premium make it a practical choice for console gamers who want a large display with adaptive sync, while the 178-degree viewing angles and anti-reflection coating suit living rooms where viewers are seated across a wide spread of positions. Users who want a capable smart TV hub with USB recording, a rechargeable remote, and voice command support will find the built-in feature set covers most everyday needs without requiring additional hardware.

Who is this NOT for?

Users who rely heavily on Dolby Vision for HDR content from streaming services or physical media will find this TV incompatible with that format, which may be a meaningful gap depending on their content library. The built-in audio system, rated at 2 x 10W with no subwoofer and no support for Dolby Atmos or DTS:X, is unlikely to satisfy those who expect immersive sound from a screen of this size without investing in external speakers or a soundbar. Additionally, users embedded in the Apple ecosystem who depend on Siri or HomeKit for smart home integration will find those features absent, and anyone requiring Chromecast for wireless casting from Android devices will need an alternative solution.

Final Verdict

The Samsung QN85Q70DAF is a large-format QLED television that covers the essentials for a living room entertainment setup with reasonable depth across display, connectivity, and smart features. Its 120Hz panel with AMD FreeSync Premium and four HDMI 2.1 ports give it genuine utility for both gaming and multi-device households, and the broad smart platform support — including Google Assistant, Alexa, and AirPlay — adds day-to-day convenience without requiring external devices. Where it falls short, notably in audio capability and the absence of Dolby Vision and Chromecast, means some users will need to supplement its built-in feature set. For viewers prioritizing screen size, viewing flexibility, and a well-connected smart TV experience over audio immersion or niche format support, the QN85Q70DAF delivers a coherent and capable package.
