Check your TV’s HDMI settings to get the best from Roku
Roku streamers can lose access to some picture or sound features if they are connected to the wrong HDMI port or if the port is not configured for enhanced capabilities. The advice matters because TV ports often differ in what they support, even when they look identical, and a quick check can help viewers get the best performance from their setup.
Most modern TVs support HDMI 2.0, which is enough for common Roku features such as 4K, HDR and Dolby Atmos, while the Roku Ultra is limited to 60Hz. Some TVs reserve Dolby Vision or other HDR support for particular ports, so users should check the manufacturer’s guidance and input settings. ARC and eARC ports are designed for audio equipment such as soundbars; computers and games consoles should generally get priority for newer HDMI 2.1 or 2.2 ports.
In short
- Check which HDMI ports support your Roku’s picture and sound features.
- Enable enhanced input settings if your TV requires them.
- Save higher-bandwidth ports for computers and games consoles.
Explained simply
Roku is a company that makes streaming players, which connect to a television through an HDMI port. HDMI carries picture and sound, but televisions can give different ports different capabilities, even when the sockets look the same.
The version of HDMI and the TV’s settings can affect which features work. HDMI 2.0 supports common options such as 4K picture, HDR and Dolby Atmos sound; some TVs may require a particular port or setting for Dolby Vision or other HDR formats.
ARC and eARC ports are intended for sending sound to equipment such as a soundbar. Newer HDMI ports may be useful for devices such as games consoles, so checking the TV maker’s guidance can help people choose a suitable connection.
