To know your TV resolution, follow these steps:
1. Press the settings button on your TV remote.
2. Look for the output resolution option in the TV menu.
3. Select the output resolution to access the list of available options.
4. Check for resolutions like 480p, 720p, or 1080p to determine your TV's resolution.
Remember, higher numbers indicate better quality. For example, 1080p is better than 720p. If you find options like 2160p or 4K, it means your TV has a 4K resolution. Additionally, you can compare the visual quality of your TV with a reference image to assess its resolution. A 4K image will have more detail and appear smoother compared to a 1080p image. The edges around objects in a 1080p image may be slightly blurry, while text will look clearer on a 4K TV.
