Most major brand flat screen TVs manufactured after 2006 support both ATSC (Advanced Television Systems Committee) and QAM (quadrature amplitude modulation) digital tuners.  ATSC is used to receive digital channels over the air.  QAM is used to receive digital channels from a cable TV provider without use of a cable box. Your TV must support QAM to function on the Spectrum provided ResNet HD Cable TV system.

Please be advised this is an informal reference guide and we can't guarantee or warrant the accuracy of the information provided. If you are making a TV tuner purchase decision, you are advised to carefully check the return and return shipping policies before you finalize any purchase.

COMPATIBLE TVS

A QAM tuner allows your TV to tune to digital or HD channels. Most, but not all, TV’s that were made after 2006 have a QAM tuner built in.

  • You can search online by make/model of your TV or reference your TV’s owner’s manual for specific model information related to what type of tuner is present in your TV.
  • An example of what the manual may say if the TV has a QAM tuner: “Built in digital tuner (ATSC/Clear QAM)”, or “NTSC/QAM“
  • The best way to check if your digital TV's tuner is clear QAM capable, is to connect your TV and use your remote control to manually tune to a few digital channels. For example, enter "25" "-" "1" (twenty-five, dash, one) and press "enter" if necessary. If you don't see a picture (i.e. NBC13), try a few more channels like. "28-1" for AMC and "33-1" for ESPN. If you can't tune any channels, your TV may not include a QAM digital tuner.


Experience shows the following well known name brand manufacturers typically DO provide QAM Tuner support and typically will function with the ResNet HD Cable TV system powered by Comcast.

SAMSUNGAll models since 2009 support QAM

NOTE: Some older models have trouble scanning all our channels.  You can try updating the firmware to fix this or cancel out of the channel scan when you reach 118 so that it stores all the channels available before the TV crashes.
TOSHIBAMost models since 2007 support QAM
VIZIORecent models support QAM

Some models support QAM but require an activation code from manufacturer.
(Many models aren't supported at all.  Please contact the manufacturer for support.)

If you are purchasing or already own one of the brands listed above, please verify that your model includes a QAM tuner. 


COMPATIBLE QAM SET-TOP TUNERS

These would ot not be required unless your TV does not have a compatible QAM tuner.  Experience shows the following stand-alone QAM Tuners (i.e. set-top cable boxes) are compatible with ResNet HD Cable TV system powered by Spectrum.  However, we can't warrant or guarantee that set-top QAM tuners will work with your specific TV. Sometimes there are compatibility issues between the QAM tuner and specific TVs.  If you choose to purchase a QAM set-top cable box, be sure you understand return policies, shipping and taxes before making any purchase decision.
