How to Convert Coaxial to VGA
By Quinten Plummer
Monitors are distinguished from television sets by their omission of TV tuners, which allows for a lower retail price than full-featured displays. Monitors that feature Video Graphics Array inputs require mediation to accept digital programming passed over coaxial lines. If your display doesn't include an embedded TV tuner, an external tuner may be the next best thing. Convert your digital cable or satellite service's coaxial output into an analog signal that's compatible with your monitor's VGA input, using an external TV tuner.
Plug your monitor's VGA cable into the "VGA Out" port on your external TV tuner. Twist the screw heads that flank the cable's VGA connector to secure the cable to the tuner.
Connect one end of a coaxial cable to the "Coax" or "Ant" port on your TV tuner. Plug the opposite end of the cable into a coaxial outlet.
Connect the TV tuner to a power outlet via its power adapter. Plug the adapter's barrel connector into the power port on the TV tuner and then plug its transformer unit into a power outlet.
Connect your monitor's power cable, if it isn't already set up. Plug the cable's female end into your monitor's power port and plug its male end into a power outlet.
Press your TV tuner's "On" button or toggle its "On/Off" switch to the "On" position. Press the TV tuner's "VGA" button and then power on your monitor.
