PC to TV Converter

A computer graphics and a television broadcast are very different in their input and output. The computer graphics is regarded as VGA and with suitable conversion it is possible to broadcast VGA in a television, though the picture quality will be reduced to some extent. This conversion requires an external hardware, or sometimes it is built in with the computer motherboard which allows it to connect to a television.

The usual video signals that are broadcasted in the television are in RF (antenna) or composite video. The signals sent out by computer graphics cards is analog RBG signal with separate sync signal such as VGA and SuperVGA in the newer cards. The broadcast resolution vary amongst computers and graphics, as in the case of computer it ranges from 640×480 upto 1024×76 and for television it is nominally 525 or 625 lines in Y-direction signal with 300-600 pixels. Computer uses non-interlaced video while television use interlaced for the picture format being broadcasted.

The television broadcast comes to a limit when displaying pictures received from a computer graphics card. It has often been seen that the picture quality has been reduced significantly as in the case of color loss, flickers, lost of details. Sometimes the graphics card becomes damaged while using with a television. Although everyone recognizes that television causes harm to the graphics card, only a few knows exactly what’s going on. It is not surprising because the conversion to PAL and NSTC are very complicated and the distortion of the graphics card is obvious.

Let us review one of the hottest converters available on the market today. It is called:
