How to Tell If Your TV Has a QAM Tuner

Most modern televisions come with a QAM (quadrature amplitude modulation) tuner, which is a chip that interprets digital television signals and allows you to see certain channels without a cable box. Televisions aren't required to have this particular feature, but most do have it included. You can check for a QAM tuner with several methods to see if you can directly receive digital channels.

Step

Use your television remote control to bring up your system menu. Search the menu for an option to scan for digital antennas. If your television is able to scan for a digital antenna signal, a QAM tuner is on your television.

Step

Locate your television's manual and check through the instructions to see whether it mentions a QAM tuner. If so, a tuner is present.

Step

Search your television's model number exactly at the manufacturer's website. The technical specifications for this television will include whether a QAM tuner is installed on the model or if it is not present.
