I Cannot Connect With the Projector
Windows 8 and presentation applications make presenting your content and slides relatively straightforward, using either a projector that connects to the video port on your computer or a network projector that connects to a computer on the local area network. If you’re having trouble connecting a projector, you can generally troubleshoot the problem yourself in just a few minutes.

Video Port Connections
Most problems with standard projectors are usually the result of a poor cable connection with the host computer, so if you cannot view your computer display on a projector, the first thing you should check is the cable connecting the two devices. Ensure that the cable connection is secure on both ends. If the projector cable uses a DVI or VGA connector, make sure the thumbscrews are tight and the plugs are flush in the ports. If using an HDMI cable, disconnect it on both ends, and then reconnect it to the PC and projector while verifying that the plugs go all the way into the slots. If the connections on both ends seem secure, inspect the video cable and look for signs of fraying or wear. If you spot any worn areas, replace the cable and try again.

Windows Display Settings
When you connect a projector to a secondary video-out port on a desktop computer or laptop, Windows does a reasonably good job of detecting the connection and configuring it automatically. However, if the resolution capability of the LCD display or monitor and the projector varies considerably, Windows may not be able to configure the projector display without intervention on your part. If connecting an older projector or one without high-definition resolution settings to a wide-screen laptop or computer with a HD-capable monitor, try reducing the resolution before attaching the cable. Open the Control Panel, click “Display” to open the Display window, click “Adjust Resolution” link, and then reduce the monitor resolution to a lower setting such as “1024×768”. After you connect the projector, you can revert to the higher settings for the monitor while leaving the lower resolution enabled only for the projector.
