Projectors today have become quite common and rather widely used. Yes, now quite a few people who use them at home for watching movies, but in school or office, this equipment is often used for presentations and other materials. Connecting the projector to a computer or laptop is a relatively simple operation which in many causes a variety of difficulties. Let's try to figure out how to do it.

Are there differences in how to connect the projector to the computer and the laptop?

How to connect to laptop and PC are almost identical, except that the laptop does not need to connect the monitor and deal with the configuration, as in the case of PC. Note that before connecting the projector, it is highly desirable to select a monitor with the highest resolution. Further, in the monitor settings, you should choose a resolution that is closest to playing with a projector.

This small detail is very important, because a high-resolution projector may not be perceived, giving the phrase "No signal". In the same case, when the resolution of the monitor and the projector are substantially different, the image quality leaves much to be desired. The reason is simple – the projector has to recalculate the image, crop and stretch it, thereby adjusting for your resolution. In this regard, you may experience problems with displaying parts of objects, or text messages (they will be impossible to read).

Cable connection

To connect the projector to a computer you will need a cable HDMI or VGA . depending on what kind of outputs you have on the PC and the projector. Preferably, of course,HDMI . because the signal is much faster and better (no extra noises). If the projector and the PC GPU different types of inputs (this happens when the computer has only DVI . and on the projector HDMI or VGA ), you can use a special adapter.

As a rule, the connection cable comes with the projector, if not, then you can buy it in any electronics store, there you can buy an adapter. Most importantly, determine exactly what kind of connector you have on the PC and the projector.

Software configuration

Once you solved all the problems with the connection of devices to each other physically, you can go to the software settings. If your computer worked before, after connecting a projector you need to reboot. Then click the right mouse button on the desktop and in context menu select the item "Properties ". In the window that appears, we need tab" Settings ».

Click on the image of the second monitor, and just below under the picture select the second display our projector. Now you need to set the optimal resolution. To find out what resolution is best for your projector, you can use the documentation. Next, put a check next to the option "Extend my Windows desktop onto this monitor" and click "Apply".

The completion of works

In the final stages remains only to restart the computer without turning off the projector, and it should work, then you can start setting up your display clarity, color gamut and other parameters. We considered the simplest way to connect the projector to a computer for the operating system Windows XP, however in Windows 7 and 8 settings are exactly the same (just the names of the individual tabs may vary).

There are also other methods of connecting the projector to a computer (for example, duplication, or use as main screen). Setting there is in a similar way and differs only in the final stage (instead of "Extend my Windows desktop onto this monitor", then choose duplicate, etc.).
