Most smart televisions are not optimized for home viewing right out of the box because manufacturers often apply conservative default settings or store modes that hinder image quality. These limitations extend directly to the television’s HDMI ports, which frequently operate below their full potential if users never adjust their internal settings.
Unlocking Full Port Bandwidth
HDMI inputs frequently default to a standard mode designed to maximize compatibility with various external devices at the expense of a bottleneck on advanced hardware like game consoles and Blu-ray players. As reported by Engadget, users can fix this on many Google-based Sony and Hisense models by locating the HDMI input options and switching each input to an enhanced setting, or a similar label. This action unlocks the full bandwidth of each port, which is required to run features such as Dolby Vision or refresh rates exceeding 60Hz. Some television models may even support advanced formats like Dolby Vision 2, HDR10+ Advanced, or refresh rates up to 240Hz, such as Samsung’s Frame Pro and OLED TVs.
Certain televisions offer multiple enhanced tiers, requiring users to prioritize settings based on connected hardware. Personal computers and gaming consoles should be assigned the best refresh rates, including Variable Refresh Rate synchronization. Meanwhile, media streaming devices and Blu-ray players only require high dynamic range settings since they rarely exceed 60Hz.
Managing Color Depth and Chroma Subsampling
Television manufacturers including LG, Sony, and Samsung often include a feature called HDMI Deep Color, which extends color depth to the levels required for high dynamic range. While no consumer television can utilize more than 10-bit color, this level provides approximately 1.07 billion shades to allow for fine gradations. Users can manually force this feature on if necessary, such as on LG televisions by navigating through the general external device settings. Any setting above standard 8-bit standard dynamic range is suitable.
Users connecting a personal computer or gaming console should also check for chroma subsampling options, which compress color data for efficiency. While compression is generally unnoticeable when watching movies or television shows, switching to uncompressed 4:4:4 color significantly improves text legibility for computer monitors and gaming setups.
