To change the screen resolution for gaming on your Smart TV, you can follow these steps:

1. Ensure optimum conditions for gaming. Make sure that your TV is connected to the internet, and that your gaming console is connected via HDMI. If using external speakers, also ensure that they are properly set up.


2. Set the TV to Game Mode. This will help preserve picture clarity during gaming. It may also affect your sound settings, so be aware of this if using external speakers.


3. Change the resolution to the optimal gaming settings. The default resolution for gaming on a Smart TV is 1080p, but check to be sure. You may need to refer to the documentation included with your gaming console.


4. Test the resolution settings. After changing your resolution settings, test to make sure that all of the visual elements appear correctly. Make sure to also check for any noticeable lag in performance.
