Selected Features

VA Panel

TCL 43S421 has a vertical alignment (VA) panel which is most commonly used in LCD TVs as it provides deeper blacks compared to the IPS panel. However, it is still limited with the viewing angle compared to the IPS panel or OLED display.

HDR10

TCL 43S421 supports 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.
