You should check the instruction manual of your TV for this information.
Common scan frequencies are 50Hz, 60Hz and sometimes 75Hz. In addition to the resolution, the computer must also use a scan frequency (also known as refresh rate) that is compatible with the TV.This can result in overscan which causes some of the screen information to be cut off or missing. Although the computer may be capable of outputting higher resolutions, the television may not be able to handle it.While newer TVs can provide higher resolutions, older models use resolutions of 640x480 and 800圆00. You should check the instruction manual of your TV to determine what resolution is supported and then configure the computer accordingly in the Display Properties found in the Control Panel of the operating system. Whether installing a video card, using a video converter, or connecting directly with a cable it is important to make sure the computer can output the video resolution properly. Use one of the following types of converters depending on the video input on your TV: Older computers use VGA/RGB ports to output the video signal, so a VGA converter may be needed to pass the signal to the TV. Note: A DVI-to-HDMI cable or a DVI-to-HDMI converter is not supported or guaranteed when attempting to connect a computer with a DVI OUT to a TV with an HDMI IN.Īlthough most computers now have HDMI output, if that port is not available then a video converter may be next best option.
