Why your Roku device might be connected to the incorrect HDMI port
Choosing the right HDMI port and cable for your Roku device is essential to ensure you get the best possible video and sound performance.
Plugging your Roku into any old HDMI port on your television can sometimes mean missing out on optimal performance or specific features. While most Roku devices do not exploit unique HDMI 2.1 features, selecting the right port ensures you avoid inferior video or sound quality. Certain HDMI ports on your TV may be required to support HDR standards like Dolby Vision, or you may need to adjust your TV's input settings to enable enhanced functionality. Additionally, you should avoid plugging a Roku into your TV's ARC or eARC port, as those labeled ports are intended for compatible output devices like soundbars and speaker systems.
