How to use the projector to watch TV?

For the projector without RF interface, if you use the projector to watch the TV screen, you need to choose a suitable TV box or set-top box. A general TV box or set-top box has an RF terminal interface. First, connect the cable TV line (or antenna) to the RF terminal interface. Then, observe the output interface of the set-top box or TV box. Generally, it should have one or more interfaces of HDMI, S-video, color difference, VGA, and DVI. For example, the high-definition set-top box in the figure below has an HDMI interface, an S terminal and a color difference interface. After reading the interface of the TV box/set-top box, take a look at the interface of the projector and select the corresponding interface to connect the two. For example, the Optoma HD71S projector in the picture below has DVI, HDMI, VGA, and color difference interfaces. By comparison, it can be found that the two have HDMI, S-video and color-difference interfaces at the same time. Use any connection method to connect the TV box/set-top box and the projector. How to use the projector to watch TV with the projector interface? After connecting the two, you only need to select the corresponding one of HDMI, S-Video, Component, VGA, and DVI as the signal input source of the projector. Then, you can use the projector to enjoy the TV screen effect. How to use the projector to watch TV? The user needs to be reminded that if there is a situation where the projector and the TV box do not have the same interface (rarely), then only need to purchase a suitable signal conversion connector to achieve the desired effect.

If possible, it is better to choose external speaker equipment, which can bring both visual and auditory shocks.
