Hisense TVs do not receive public broadcasting channels because they do not have built-in tuners that are compatible with the ATSC (Advanced Television Systems Committee) standard used for over-the-air broadcasting in the United States. This means that without an external tuner or antenna, Hisense TVs are unable to pick up public broadcasting channels. To access these channels, viewers would need to connect an external tuner or antenna to their Hisense TV. **

Samsung Smart TVs do not support private channels because they use the Tizen operating system, which does not have the capability to add private channels like some other platforms, such as Roku. Tizen is a closed system that does not allow for the installation of third-party channels or apps that are not approved and available through the Samsung app store. This means that users are limited to the channels and apps that are officially supported by Samsung, and cannot add private or unauthorized content. **

4K TVs do not necessarily have better audio quality than Full HD TVs.

However, it is important to consider the quality and specifications of the specific TV or projector when choosing a large screen to ensure optimal picture resolution. **

Tube TVs generally consume more power than LCD TVs. This is because tube TVs use cathode ray tubes to produce images, which require a significant amount of energy to operate. On the other hand, LCD TVs use liquid crystal displays, which are more energy-efficient and consume less power. This means that LCD TVs are more environmentally friendly and can help reduce electricity costs compared to tube TVs. **
