4. General - I have a regular High Definition TV, do I need to buy a 4K TV to use a ZapperBox?

You do not need to buy a new TV. However, regular HD TVs typically support a resolution of 1920x1080. A 4K TV supports a resolution that is 4 times higher or 3840x2160. 4K TVs are also referred to as UHD, or Ultra High Definition TVs. A new feature called HDR (High Dynamic Range) for rich colors is supported in most new 4K TVs. Technically, it is possible for regular HD TVs to also support HDR, but that is unlikely. ATSC 3.0 has three main advantages: 4K, HDR and Dolby® AC-4. If you have an HDR capable TV you can enjoy HDR colors. If your TV does not support HDR, you can still enjoy Dolby® AC-4 features. All ZapperBox models support HDR10 and HLG formats for HDR. Dolby Vision also works with HDR10. ZapperBox does not support SL-HDR1 at this time.
