Haier 75S800QT 75"

Manufacturer: Haier

The Haier 75S800QT is a 75-inch QLED television built around a 4K LED-backlit LCD panel with a native resolution of 3840 x 2160 pixels. It runs a full smart TV platform with built-in Chromecast and AirPlay, Google Assistant voice control, and smartphone remote support, making it a reasonably well-connected option for everyday home viewing. A built-in web browser, sleep timer, and child lock round out the software feature set, and a two-year warranty is included.

On the display side, the set supports HDR10, Dolby Vision, and HLG, though HDR10+ is absent, and no adaptive sync technology is listed. The viewing angles reach 178 degrees both horizontally and vertically, and an anti-reflection coating is applied to the panel. Connectivity includes four HDMI 2.1 ports, two USB ports, a single RJ45 ethernet jack, a 3.5mm headphone output, and Miracast support for wireless screen mirroring. Audio output is handled by a stereo speaker system rated at 2 x 10W with Dolby Atmos and Dolby Audio decoding, plus both HDMI ARC and eARC for connecting external audio equipment. VESA wall mounting is supported.

Pros
  • Four HDMI 2.1 ports provide ample high-bandwidth connections for modern devices such as consoles and media players
  • Dolby Vision and Dolby Atmos support covers both HDR picture and immersive audio decoding in a single set
  • Built-in Chromecast and AirPlay enable wireless casting from a wide range of devices without additional hardware
  • Wide 178-degree viewing angles both horizontally and vertically reduce picture degradation when viewed off-axis
  • HDMI eARC support allows high-quality audio passthrough to compatible soundbars and AV receivers
  • VESA wall mount compatibility provides flexible installation options for the 75-inch panel
Cons
  • HDR10+ is not supported, limiting compatibility with content mastered in that specific format
  • No adaptive synchronization technology is available, which reduces the set's suitability for gaming use
  • The built-in speakers are rated at only 2 x 10W with no subwoofer, which is modest output for a 75-inch display
  • Amazon Alexa and Apple HomeKit/Siri are not supported, restricting smart home integration for users in those ecosystems
  • No ambient light sensor is present, so the picture cannot automatically adjust to changing room lighting conditions
  • The remote control is not rechargeable, requiring conventional battery replacement
Who is this for?

The Haier 75S800QT is well-suited to living room environments where a large screen and broad streaming ecosystem access are the primary requirements. The 75-inch QLED panel with Dolby Vision, combined with built-in Chromecast and AirPlay, makes it a practical choice for households that cast content from phones, tablets, or laptops across different platforms. Users embedded in the Google ecosystem will find Google Assistant voice control a natural fit for day-to-day navigation. The four HDMI 2.1 ports also make it a capable hub for connecting multiple source devices simultaneously, and HDMI eARC support suits those who want to pair the set with an external soundbar without audio quality compromise.

Who is this NOT for?

Users who prioritize gaming performance will find this set limiting, as there is no adaptive synchronization technology listed, which can affect the smoothness of fast-paced gameplay. Those seeking deep smart home integration with Amazon Alexa or Apple HomeKit will need to look elsewhere, as neither is supported. The built-in speaker system — a stereo pair rated at 2 x 10W with no subwoofer — is unlikely to satisfy viewers who expect impactful audio from a 75-inch display without a separate audio setup. Additionally, the absence of an ambient light sensor means the picture will not self-adjust to shifting room conditions, which may be a drawback in spaces with variable lighting throughout the day.

Final Verdict

The Haier 75S800QT is a 75-inch QLED smart television that covers the core bases for everyday home viewing with a respectable feature set. Its four HDMI 2.1 ports combined with Dolby Vision and built-in Chromecast and AirPlay make it a well-connected option for households that stream across multiple platforms and connect several source devices simultaneously. The inclusion of HDMI eARC, Dolby Atmos decoding, and Google Assistant voice control adds further practical value for living room use. That said, the absence of adaptive sync, HDR10+, and a more capable built-in audio system means it is best matched to general viewing rather than gaming or audiophile-oriented setups. For users seeking a large-screen smart TV with solid connectivity and broad HDR coverage for everyday use, the 75S800QT presents a coherent and functional package.
