Wireless connection

To connect the projector wirelessly, all you need to do is take advantage of Wi-Fi technology . To do this, a special adapter, resembling an ordinary USB flash drive in its appearance, must be placed in the USB socket of the projector . A light on the adapter will light up to signal that the device is working and is suitable for use. Some advanced projector models, for example, Epson EH-TW650, have a built-in module wireless connection, therefore do not require the use of a separate adapter.

As for laptops, to which in this case the device is connected using Wi-Fi, most of them do not need additional equipment, but sometimes they require the installation of special software or additional drivers.

A wireless connection has many benefits . Avoiding multiple cords simplifies the process and does not have to be hidden anywhere. The projector is connected quickly, it can work without any problems even at outdoor events.

Wired methods

Depending on the connectors present, this may be VGA, HDMI or USB connection . The connection diagram is almost the same in all three cases, but has some nuances.

VGA

Since the VGA connector was at its peak of popularity several decades ago, today it can only be found on outdated models … In addition, it should be understood that only an image will be output, and for sound an additional cable is required . The small connector has three lines and is usually colored bright blue. It is necessary to insert a cable of the same color into it, which is then additionally fixed with a pair of built-in screws.

However, it should be understood that video resolution and image quality are likely to suffer due to the narrow space of the transmission cable. Before connecting both devices, you need to download and install a special driver on your personal computer capable of transmitting an image from the screen to the projector.

HDMI

The HDMI connection is considered the most reliable when connecting a computer and a projector . The connection procedure is the same as using the VGA connector. Before starting, be sure to turn off both devices, otherwise equipment failures and system malfunctions are possible. Next, the cable is connected to the projector, then to the computer, and then you need to activate both devices. One of the main advantages of an HDMI connection is the ability to simultaneously transmit both sound and picture, and with the maximum resolution.

Therefore, further you will need to adjust the resolution by changing the data in the computer settings. The system of displaying the picture on the screen is similar to the system in Windows 7, but with a slight change in the names. In this case, instead of “Duplicate”, the message “Duplicate” will appear, and the items “Projector only” or “Screen only” will also be present. A specific key combination that changes depending on the laptop model will allow you to change these modes.
