How can you make your tv HD?

A standard definition television will never be a high definition television. Standard definition televisions use either 480 (NTSC) or 576 (PAL) lines to form a complete image. High definition uses 720 or 1080 lines to create the image. Unless the television has been designed to display high definition, it will not display a high definition signal. However, converters are available that will process a high definition signal and convert it to 480 or 576 lines. The output of one of these down converters can then be shown on a standard definition television. Be aware that once the signal is converted to standard definition, the image quality will be standard definition because the fine detail found in a 1080 line image is lost during the conversion. The use of a down converter only provides the means of watching high definition content and will never offer HD quality. Some LCD televisions do not offer HD television reception but may have a VGA input for use with a computer. Normally, the VGA resolution is higher than standard definition television; a converter that will take an HD signal and process it to a VGA signal may provide better results. Typically, LCD displays capable of supporting computer displays will have 768 lines or perhaps even higher. A conversion to VGA may well provide a higher quality result but the final quality is dependent on the display, the converter and the incoming signal. Some experimentation may be required and it may me less expensive to simply purchase an HD television rather than a good quality converter.
