The U68H Series expands on picture quality, audio upgrades, and makes the transition to the Google TV operating system. The U68H series adds HDR10 Adaptive and Dolby Vision IQ to its already long list of supported HDR formats. These technologies incorporate environment lighting considerations to their HDR interpretations making HDR more accurate depending on the ambient lightning in your room. Game mode gets an upgrade to Game Mode Plus and adds variable refresh rate (VRR) for smoother gaming on next generation game consoles. With WiSA ready software, the U68H is now equipped to connect to the latest WiSA compatible speakers for a complete surround sound experience without the need for running speaker wires throughout the room.
