No more long cable connection problems

Enhanced wireless image brightness and clarity
up to 50% brighter picture versus cabled connections
Wireless projections can deliver clearer images with less signal noise and data loss when compared with using a long VGA cable. Thorough testing also found the ViewSync 3 outputs an up to 50% brighter image, compared to projection through a 20-meter VGA cable.

Solve the problem of wireless transmission lag

Dual band wireless 2.4G / 5GHz switch
Stable wireless projection and smooth video playback quality
2.4GHz is a very popular bandwidth for most wireless devices, which can easily cause transmission lag. The advantage of a 5GHz network is that it can have twice the link speed, which increases the quality for multi-media broadcasting. WiFi Dual Band support utilizes flexible usage, by providing either 2.4G or 5GHz network.
