Methods for connecting a video projector to a laptop

Connecting the projector to a laptop is carried out by simple manipulations, but, unfortunately, along this path there are often difficulties. When the devices refuse to mate automatically, this means that the standard settings of the system have been brought down, or these devices simply “do not understand” each other. How to connect a projector to a laptop in this case? The connection is configured manually: for this, the operating system provides for certain key sets. In the absence of such, the parameter setting is carried out by forcing configuration changes.

Wired connection

A multimedia projector, regardless of model, connects to a computer or laptop via VGA or HDMI cable. For high quality HDMI content would be preferable.

Elementary connection algorithm:

• disconnect both devices from the network before turning on the projector;
• Insert the plug into the appropriate connector;
• Turn on the projector, then the computer.

In cases where the desired connector is not available, you can use special adapter. This can happen when a video card has only a DVI connector, and a VGA or HDMI projector. Using an adapter slightly reduces the quality of the content. The projector turns on first, otherwise the computer does not see it.

Wireless connection

You can also synchronize devices via Wi-Fi protocol, today this method is gaining popularity. To activate you need install drivers, but in the case of Windows 7, it is usually quite regular.

If you lose the disc, the application can be downloaded on the Internet from the site of the projector's brand.

Before you connect the projector to a laptop, you need to install Wi-Fi antennas in the USB-connectors of the projector and PC, they look like a small USB flash drive. A green indicator light indicates that the connection was successful.

It is worth noting that not all projectors that support Wi-Fi, will project the video. Some models can be connected only to control the equipment, this nuance needs to be clarified with the purchase. Wired connection is more reliable and practical: HDMI plug, for example, is designed to transmit video of excellent quality without interference.

We display content in the right mode

Theoretically, after connecting the cable to the appropriate connector, the picture should appear automatically. In some cases, when the settings are incorrect, the user must make the necessary changes to display the content. It is known that each version of the operating system has its own characteristics, because there is no single procedure.
