Hisense 65" 4K Ultra HD QLED Smart TV - Black - E78

QLED (Quantum Dot Light Emitting Diode) technology uses quantum dots to produce highly pure and vibrant colors. In the Hisense E78QTUK, this means millions of pixels light up individually, and Quantum Dot Colour shows over a billion shades, resulting in super-sharp images and incredibly realistic colors.

4K Ultra HD refers to the resolution of the screen, which is 3840 x 2160 pixels. This is four times the resolution of Full HD (1920 x 1080), providing significantly more detail and clarity, especially on larger screens like this 65-inch model.

The Hi-View AI Engine uses advanced artificial intelligence to analyze and upscale content in real-time. It enhances resolution, brightness, contrast, and color frame by frame, making whatever you watch look as good as possible, regardless of its original quality.

Dolby Atmos is an audio technology that delivers multidimensional sound, creating an immersive soundstage where sounds seem to come from all directions, including above. Dolby Vision is an advanced HDR (High Dynamic Range) video technology that offers astonishing brightness, more vibrant colors, and deeper contrast, ensuring a highly cinematic and lifelike viewing experience.

Game Mode Plus is a feature that optimizes the TV for gaming, reducing input lag. ALLM (Auto Low Latency Mode) is part of Game Mode Plus and automatically detects when a gaming console is connected and switches the TV to its lowest latency settings, ensuring ultra-smooth and responsive gameplay without manual adjustments.

Freely is a built-in service that allows seamless access to live and on-demand content over the internet. With Freely, you do not need a traditional aerial to watch live TV channels or access catch-up services, simplifying your setup and offering more content options.

To clean the screen, gently wipe it with a clean, dry, soft, lint-free microfiber cloth. For smudges or fingerprints, you can slightly dampen the cloth with water or a specialized TV screen cleaner (do not spray directly onto the screen). Avoid using harsh chemicals or abrasive materials.

Check that the power cable is securely plugged into both the TV and the wall outlet. Ensure the correct input source is selected on the TV for your connected device (e.g., HDMI 1). Try restarting the TV by unplugging it for 30 seconds and plugging it back in.

Verify the source content is high-resolution (e.g., 4K). Check the cable connections from your external devices (HDMI cables should be securely connected and not damaged). Go to the TV's Picture Settings menu and experiment with picture modes (e.g., Standard, Cinema, Dynamic) or adjust individual settings like brightness, contrast, and sharpness. Ensure the Hi-View AI Engine is enabled if available in settings.

Ensure the TV is connected to your Wi-Fi network. Go to the Network Settings and confirm the connection status. Try restarting your home router and modem. If connected, try restarting the TV. Some apps may require updates, check the app store or TV system updates.

Check the TV volume and ensure it is not muted. Verify the audio output settings on the TV are correct (e.g., TV Speakers, External Audio System, HDMI ARC/eARC). If using external devices, check their volume levels and audio output settings. Ensure all audio cables are securely connected.
