What causes a grainy TV picture?
The grainy picture on your TV can be attributed to several factors, primarily poor signal quality. This could occur due to environmental interferences, damaged cables, or even insufficient signal strength from your service provider. If you’re watching over-the-air broadcasts, obstacles like buildings or trees may disrupt the line of sight to the broadcasting tower, leading to a degraded image quality.
Another major reason for a grainy picture is the resolution mismatch between your TV and the content being displayed. If you’re attempting to present high-definition content on a standard-definition screen, or if the source material is of low quality, the result can often be a pixelated or grainy appearance on the display. Upgrading to higher-quality content or checking your equipment’s compatibility can mitigate this issue.
