The SU Cable TV system requires a television, DVR or other tuner device with a QAM tuner (specifically QAM 256). You must check the specifications from your manufacturer to determine if it includes the required tuner. The types of tuners currently in use in the United States are listed here for your reference.

Television Compatibility

We have compiled the following information about television compatibility, and provide this list an informal reference for newer devices. This information is compiled from staff and student reports, and is not intended to be complete. We cannot guarantee the accuracy of this information. You should verify the specifications when you make a purchase.


Please be advised that less expensive TVs sometimes come with a lower quality QAM tuner that may be unable to tune all of the channels. We have found this to be true of bargain brands such as Dynex, Insignia, as well as some low-cost models from Vizio. If that is the case a digital conversion box can be purchased.

Digital Conversion Boxes

If your television does not support a QAM tuner, you can update your television or purchase a digital conversion box. Just like the TV, you should ensure that the conversion boxes includes a QAM tuner, and not just an ATSC tuner. Most tuner boxes available at electronic stores from over-the-air digital TV transition do not include this tuner, so be sure to verify the specifications from the manufacturer. The following boxes have been tested by the university for compatibility with our system.
