Comparison TouYinger T9A vs TouYinger T9

Wi-Fi standard supported by the projector.

Wi-Fi is known mainly as a method of wirelessly connecting to the Internet and local networks. In addition, more recently, this technology has also been used for direct connections between wireless devices. Accordingly, the methods of using Wi-Fi in projectors may also be different. Thus, some models are capable of connecting to local networks to work with content via DLNA (see above); in others, such a connection is used for control from a computer or other network device; in others, a “remote control” like a smartphone or tablet can connect directly via Wi-Fi.

As for Wi-Fi versions, the most popular options in modern technology - Wi-Fi 4 (802.11n) and Wi-Fi 5 (802.11ac) - are quite compatible with each other, and the difference between them in this case is not critical. Therefore, you don’t need to pay much attention to these details when choosing.

There are also Wi-Fi ready projectors, which do not have Wi-Fi out of the box, but when connecting the appropriate adapter (purchased separately) are capable of a wireless connection.

Miracast technology is designed to transmit streaming video over an IEEE 802.11n wireless channel. This technology is well suited for broadcasting "heavy" high-quality content. Thanks to Miracast, you can display video from a smartphone or a picture of a tablet / laptop screen on the projector in a matter of seconds. Miracast can be considered an optional Wi-Fi Direct application.

The processor performs the function of converting the input signal; the overall image quality largely depends on its type. The more powerful CPU is used in the projector, the greater the depth of textures the picture will have. Of course, powerful high-performance processors are found mainly in advanced projectors. Inexpensive models of projectors receive a standard CPU with basic capabilities.
