Samsung QE75QN88DBTXXU 75"

Manufacturer: Samsung

The Samsung QE75QN88DBTXXU is a 75″ QLED television that combines a large-format LCD panel with LED backlighting to deliver a 4K Ultra HD picture across its 3840 x 2160 pixel display. Running Samsung's built-in smart TV platform, it supports AirPlay, Google Assistant, and Amazon Alexa, while also offering voice commands and smartphone remote control. The set carries an AMD FreeSync Premium Pro certification alongside FreeSync and FreeSync Premium, making it a capable option for variable refresh rate content through its four HDMI ports.

On the display side, the panel renders at 59 ppi with a 10-bit color depth capable of showing over one billion colors, and it supports HDR10, HDR10+, and HLG formats, though Dolby Vision is not included. Horizontal and vertical viewing angles both reach 178 degrees, and an anti-reflection coating plus ambient light sensor are built in. Audio is handled by stereo speakers with a subwoofer, Dolby Atmos, Dolby Audio, and both HDMI ARC and eARC outputs. Connectivity includes Wi-Fi 5, Bluetooth 5.2, two USB ports with USB recording support, one RJ45 port, and Miracast, while the unit draws 121W during operation and just 0.5W on standby, carrying an EU energy label of F.

  • The remote control is not rechargeable, requiring conventional battery replacement

Who is this for?

This television is well suited to living room setups where a large 75″ screen and broad viewing angles of 178 degrees in both directions allow multiple people to watch comfortably from different positions. Users who engage in console or PC gaming will find the AMD FreeSync Premium Pro support and 100Hz refresh rate useful for reducing screen tear during variable frame rate content. The wide range of smart features — including AirPlay, Google Assistant, Alexa, voice commands, and a built-in browser — makes it a practical fit for households that rely on voice-controlled or app-driven entertainment ecosystems, particularly those already using Google or Amazon smart home devices.

Who is this NOT for?

Users who require Dolby Vision support for their streaming or disc-based content will find this set lacking, as that HDR format is not included despite HDR10+ and HLG being present. Those invested in the Apple ecosystem may also find the absence of Siri and Apple HomeKit compatibility a notable limitation. Additionally, anyone looking to connect headphones directly will be unable to do so through a 3.5 mm jack, and the lack of an external memory slot makes local storage expansion impossible, which could frustrate users who rely heavily on USB recording without an external drive solution.
