4K Ultra HD: Refers to a display resolution four times higher than full HD, with 3840×2160 pixels in a 16:9 aspect ratio. This results in approximately 8.3 million pixels, offering sharp details and realistic images that can be viewed up close without pixelation.
Full Array Local Dimming: An LED backlighting system with LEDs arranged in a grid behind the LCD panel, divided into zones that dim independently. This provides deeper blacks and even brightness distribution across the screen.
High Dynamic Range (HDR): Enhances picture quality by expanding color and contrast, producing more vivid images with deeper blacks and brighter whites, similar to features used in digital photography.
Quantum Dots: Tiny semiconductor particles embedded in a film layer that adjust backlight colors, creating a wide color spectrum and more accurate colors on the screen.
High Efficiency Video Coding (H.265): Also called HEVC, this technology compresses large 4K videos for smoother streaming and faster downloads, doubling compression efficiency over H.264 used in 1080p videos. It’s essential for 4K streaming devices.
VP9: Google’s alternative video codec that encodes 4K Ultra HD content, ensuring compatibility with streaming platforms like YouTube for optimal playback.
HDMI 2.0a: The latest HDMI standard supporting 4K at 60 frames per second with HDR, ensuring high-quality video and audio transfer from source devices.
HDCP 2.2: An advanced digital content protection protocol necessary for playing 4K content securely, requiring compatible HDMI ports and devices.
Upscaling: A feature that improves lower-resolution videos, such as 720p, to look better on 4K screens, often found in DVD players and streaming devices.
