Nano Cell Technology on LG 49SM8600PLA

LG 49SM8600PLAuses nanocell technology on its LCD display. This 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.

IPS Panels

Both TVs have in-plane switching (IPS) panels. Such panels are 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 panels can provide better viewing angles and color accuracy compared to the VA panels.

HDR10

LG 49SM8600PLA and LG 55UM7450PLA support HDR10 which was announced on August 27, 2015, by the Consumer Technology Association and uses the wide-gamut Rec. 2020 color space. It is not backward compatible with SDR. It sends static metadata via video stream to the TV which calibrates its screen brightness and color according to that. HDR10 is technically limited to a maximum of 10,000 nits of brightness and uses 10-bit color which corresponds to 1024 shades of the primary RGB colors.

Dolby Vision on LG 49SM8600PLA

LG 49SM8600PLA also supports Dolby Vision which is an update to HDR10 by adding dynamic metadata that can be used to more accurately adjust brightness levels up to 10,000 nits on a scene-by-scene or frame-by-frame basis and supports up to 12-bit color depth (4096 shades of RGB) and 8K resolution.
