The City of Monroe Cable cannot provide a specific list of televisions or manufacturers that provide televisions with QAM 256 tuners that would be compatible with the City of Monroe Cable’s digital signals due to the vast number of makes, models, manufacturers, and dates of production, but we have compiled some general information for your reference.

The City of Monroe Cable suggests speaking with a professional salesperson who can determine whether or not the television you want to buy is equipped with a QAM 256 tuner. You can also look at the television’s manufacturer’s specifications to see what type of tuner it has.
