How to Choose the Correct HDMI Port for Gaming

Step by step

1. 1 min

   Inspect the display labels

   Locate the HDMI inputs on the back or side of your television. Look for ports labeled 'HDMI 2.1', '120Hz', or '4K/120'. If ports are not explicitly labeled, consult the printed manual or the manufacturer support page for your specific model number.

   Note: Not all HDMI ports on a single television support the full 48Gbps bandwidth required for 4K 120Hz gaming.

   Utilize an Ultra High Speed HDMI cable

   Verify your HDMI cable is marked 'Ultra High Speed'. This certification ensures the cable can handle the 48Gbps bandwidth necessary for high-resolution, high-refresh-rate gaming. Connect one end to the identified HDMI 2.1 port and the other to your console or GPU.

   Note: Standard High Speed cables will limit your signal to 4K 60Hz or lower.

   Enable HDMI Enhanced Format

   Navigate to the TV settings menu using your remote. Locate the 'Inputs' or 'External Inputs' section and select 'HDMI Signal Format'. Switch the setting to 'Enhanced Format' or 'VRR Mode' to allow the port to receive the full bandwidth signal.

   Note: Failure to enable this setting often results in a black screen or a 60Hz cap regardless of the cable used.

   Confirm output on the console

   Access the 'Video Output' settings on your gaming console. Ensure '4K Transfer Rate' is set to 'Automatic' or 'Enable' and check that the 'VRR' (Variable Refresh Rate) setting is toggled to 'Automatic'. The system will now verify the handshake with the television.

   Note: If the console reports 'Your TV does not support 4K 120Hz', re-check that the cable is fully seated in the port.

   Run a system diagnostic test

   Select 'Video Output Information' within the console settings menu. Confirm the 'Supported Frequencies' list includes '120Hz' and that 'VRR' is active. This confirms the link between the specific HDMI port and the console is functioning at maximum specifications.
