4K Ultra HD: Represents a display resolution four times greater than standard 1080p, with 3840×2160 pixels in a 16:9 aspect ratio. This high pixel count results in detailed, sharp images that can be viewed up close without pixelation.

High Dynamic Range (HDR): Improves picture realism by increasing contrast and expanding color range, leading to brighter highlights and richer blacks.
Quantum Dots: Nanocrystals embedded in the display that produce vivid, diverse colors by controlling backlight emission.
HEVC (H.265): Advanced compression technology that reduces large 4K video files into smaller streams, allowing smooth playback over the internet and efficient streaming.
VP9: Google’s codec used primarily for YouTube 4K streaming, ensuring high-quality video delivery on supported devices.
HDMI 2.0a: Latest HDMI standard capable of transmitting 4K HDR content at 60 frames per second for optimal picture quality.
HDCP 2.2: Security protocol that protects 4K content from piracy, requiring compatible devices for secure transmission.
Upscaling: Enhances lower-resolution videos, like 720p or DVD quality, making them appear clearer on 4K screens for a better viewing experience.
