We give LG 55SK9000PUA TV 64 overall score out of 100. Our ranking system is based on the display specifications, video, audio and other features, connectivity and format support.

In this section we highlight pros and cons of LG 55SK9000PUA.

IPS Panel

LG 55SK9000PUA has an in-plane switching (IPS) panel which is not commonly used in LCD TVs as they suffer from light leakage which lead to the lower contrast and poor HDR experience. However, this type of panel can provide better viewing angle and color accuracy compared to the VA panel.

Nano Cell Technology

LG Nano Cell technology uses particles to absorb unwanted light wavelengths and enhance the purity of the red and green colors displayed on the screen. In addition, they create subtler, more accurate colors that stay true, even at wide viewing angles. So, even if the whole family is gathered around the TV, everyone has the best seat in the house, whether they’re front and center, or across the room and off to the side.

Full-Array Local Dimming

The TV has Full-Array Local Dimming technology with multiple zones throughout the display. Individual zones of LEDs can light up independently which enhances black levels, shadow details and decreases level of light bleed in dark parts of the image. This gives higher contrast with increased picture quality which is very important for HDR reproduction. Higher number of zones gives better control over local dimming and less blooming around the bright objects and subtitles.
