Preliminary operations

Before seeing in detail how to project images on the wall, it is good that you explain what are preliminary operations that you have to do in order to be sure that the wall of your home or room where you want to project is suitable for the purpose.

To get respectable results without spending astronomical figures, you need to use the projector on a white wall painted with a matte and unsaturated matt paint. This is an assumption basic to ensure that the quality of the images and colors is optimal.

If, on the other hand, you are willing to invest some extra money to make sure that one of the walls of your home or premises is optimized for the projection of images, you can buy some paints optimized for projection walls: they are found in specialized stores or in online stores, such as Amazon.

An even better solution would be to buy projection sheet which has prices that are not too dissimilar to those of the special paint I mentioned a few moments ago and, to put it plainly, ensures better results in terms of colors, quality and image rendering.

It’s up to you to choose the solution that best suits your needs taking into account the maximum budget you can spend, the distance between the wall and the projector, the size of the room where the projection will be carried out and anything else. Once you have properly equipped the wall, you can finally connect the projector in your possession to the computer by following the steps indicated in next chapter.

As for the projector, however, if you don’t currently have one, you can buy one both in the main electronics chains and on Amazon or on other online stores (there are also quite cheap models, with prices starting from 70 euros about, it then depends on the technical characteristics and the video quality that you want to have). Before buying one, however, I highly recommend you take a look at the buying guide dedicated to the best projectors, so as to avoid making a bad deal.

How to project images on the wall with the projector

Now that we have clarified the most practical aspects of the matter, you can finally proceed with the projection of the images on the wall by connecting your projector to your computer. Before making the software connection between the two devices, however, you must first make the physical connection between the projector and the computer using a cable HDMI or one of the doors VGA/DVI present on the device (depending on the type of projector and computer in your possession). Once you have established the physical connection between the projector and the computer, you can go to the software configuration. Below you will find out how to proceed.

Physical connection

If your computer has one HDMI port, you can connect between the computer and the projector by simply using a HDMI cable.

If your computer is equipped with USB Type-C ports only, you will need to purchase a USB-C to HDMI / VGA multiport adapter, like the ones I linked to below.

After finding everything you need to make the connection between your PC / Mac and the projector, all you have to do is turn on both devices by pressing on the respective power buttons and make the wired connection. If your computer has a HDMI port, for example, connect it to the projector via the HDMI cable in your possession.

If the computer does not have an HDMI port or if the projector has only the VGA input, instead, take theadapter you purchased and, after connecting it to your computer, connect it to HDMI or VGA port which is present on the projector.

Software configuration

After establishing the physical connection between the computer and the projector, you can finally proceed to the software configuration of the two devices.

If you are acting from a PC Windows 10, type in the search bar located at the bottom left the words “projects to another screen“, Presses on the first occurrence that is found and then click on one of the items in the menu that appears laterally on the right (eg. Duplicate, to reproduce the Windows desktop with the projector; Extend to use the projector as an extension of the PC desk or Second screen only, to transform the projector into the only computer screen), depending on the type of configuration you want to create.

If you use a PC equipped with Windows 7, open the Control panel of Windows, search for the term “projector” in search bar placed at the top right and click on the item Connect to projector. Again you can select various options (Duplicate, Extend or Projector only).

Alternatively, if you use Windows 7 or Windows 8, you can press the key combination Win + P on your PC keyboard and call up the quick control panel for the projector and the additional displays that allows you to do everything you can do through the control panel, but more quickly.

If you are acting as a Macinstead go to the section Monitor of the System Preferences (the gray icon with the gears present on the bar Dock) And configure the behavior of the projector from there: based on the type of configuration you want to make, select the tab relating to layout desktop and affix the tick on the option you prefer (e.g. Duplicate monitor). Simple, right?
