Determine if your TV is HD or SD.
High definition is set apart from standard definition because of the overall resolution of the image. While standard definition video has 480 lines of horizontal resolution, high definition comes in either 720 or 1080 lines of horizontal resolution. This provides you with over twice the image quality of standard definition (if using the highest quality HD picture). To determine the definition of the video on the television, there are several locations and documents you are able to use as reference points.
Instructions
1. Check the packaging of the television. It is going to state the screen resolution of the TV right there on the box. Additionally, most HD televisions indicated it is "HD" in large font, as the manufacturer wants the consumer to know the TV provides improved video quality.
2. Look into the user manual of the TV. The user manual indicates the specifications of the television, including the image resolution.
3. Check the rear of the television. On the back of the TV, near the connection ports, there is a panel with hardware information regarding the television. This includes the screen resolution of the TV set.
4. Power on the TV, press the "Menu" button and choose "Picture." Displayed in the picture options is the settings of the TV, including the screen resolution. If the resolution is 720 or higher you know the television is high definition.
