Here is a summary of the key features, with important clarifications on its technology and performance:

📺 Picture Quality & Technology

• QLED Color: Features 100% Color Volume with Quantum Dot technology for rich, vibrant, and accurate colors, enhanced by Quantum HDR [1.1, 1.2].
• Backlight (Crucial Note): The Q70A uses a Dual LED Backlight system, which employs both warm and cool LEDs to enhance contrast and color tone [1.1, 1.2]. However, it uses Edge Lit lighting and does not have Full-Array Local Dimming (FALD) [1.4, 2.7, 3.1]. This means that while it has excellent overall contrast, the black levels and shadow detail in very dark scenes are not as deep or precise as models with FALD (like the Q80A and higher) [3.1].
• Processor: Powered by the Quantum Processor 4K, which uses AI upscaling to enhance non-$4\text{K}$ content [1.2].

🎮 Gaming Features

• Native $120\text{Hz}$: The TV has a native $120\text{Hz}$ refresh rate for smooth motion clarity [1.2].
• HDMI 2.1 Ready: It supports many next-gen gaming features, including $4\text{K}$ at $120\text{Hz}$, Variable Refresh Rate (VRR) via FreeSync Premium Pro, and Auto Low Latency Mode (ALLM) [1.1, 2.4].
• Connectivity Limit: Only one of the four HDMI ports (HDMI In 4) supports the full set of HDMI 2.1 features like $4\text{K}@120\text{Hz}$ [2.4, 2.5].
• Game Bar: Includes the Game Bar menu for making real-time adjustments to screen ratio, input lag, and other settings [1.1].

🔊 Smart & Audio

• Smart Platform: Uses the Tizen smart platform, which offers a robust selection of apps and smart features like the Universal Guide and Multi View [2.1].
• Voice Assistants: Includes Bixby and Amazon Alexa built-in [1.2].
• Audio: Has a $2\text{ Channel } \times 10\text{W}$ output (total $20\text{W}$) with Object Tracking Sound Lite™ and support for Dolby Digital Plus [2.1]. Most reviews suggest adding a soundbar for an improved audio experience [3.3].
