Consumer-grade televisions are great for your living room, but often fall short in hospitality guest rooms. Here's why:

  • Warranty - Commercial TVs come standard with a robust, 2-year warranty with option to purchase extended coverage. Consumer TVs have a 90 day limited warranty.
  • Technology - Hospitality TVs are equipped with Digital Rights Management (DRM) that protects HD programming from illegal duplication. DRM is required to deliver HD content to your guests.
  • Security and Maintenance - Hospitality TVs contain features that allow management to control access from one centralized location.
