It is important to measure the distance between where the TV will be positioned, and where it will be viewed from. We recommend viewing distances are at least double the length of the diagonal screen...

The maximum resolution refers to the highest resolution the TV screen can display. This resolution is determined by the number of pixels the screen has and is generally expressed as width × height. Higher resolutions provide sharper images with more detail. Common resolutions include HD Ready (1280 × 720 pixels), Full HD (1920 × 1080 pixels), 4K Ultra HD (3840 × 2160 pixels) and 8K Ultra HD (7680 × 4320 pixels). Higher resolutions, such as 4K and 8K, are often useful for large screens or for high-resolution applications such as gaming or watching movies in ultra-high definition.

Panel refresh rate is a critical parameter that affects the quality and smoothness of the image displayed on the TV screen. The frequency is expressed in Hertz (Hz) and indicates how many times per second the screen image is refreshed. Higher refresh rates, such as 120 Hz or 240 Hz, provide a blur-free and jerk-free picture, which is ideal for watching fast-paced sporting events or playing action video games.

Backlighting is a key aspect of display technology that affects the picture quality of the TV. It is the light source used behind the TV screen to illuminate the pixels. Different types of backlights such as Edge LED, Direct LED, Mini LED and Dual LED provide different benefits in terms of contrast, brightness and image uniformity. Choosing the right type of backlight can have a big impact on the overall TV viewing experience.
