Premium Picture

TCL’s 5-Series marries superior 4K UHD picture quality with Dolby Vision HDR for a stellar imaging experience. The 5-Series’ HDR Dynamic Contrast technology uses information embedded in the Dolby Vision content to optimize every scene for an accurate display of details in the bright and dark areas simultaneously, unlike other HDR formats that have a set brightness level for all content. The 5-Series models’ iPQ Engine™ provides precise color replication while HDR Pro Gamma significantly improves HDR performance in any setting.
