How to install, connect and customize the projector

Projection equipment is gaining increasing popularity nowadays. It is employed for obtaining a wide screen for home cinema, for displaying presentations in offices, and for numerous other purposes. To ensure a high-quality image, it is crucial to devote considerable attention to the installation of the projector. This process involves selecting a suitable location, mounting and configuring the device itself, as well as optimizing the acoustics and screen. Each of these procedures will be thoroughly explained in a step-by-step manner in the following guide.

Choosing a location

In order to ensure a high-quality image and an optimal viewing experience for all viewers, it is imperative to carefully choose both the projector and screen placement.

For the screen

When selecting the wall for your screen, it is important to choose an area that does not receive direct sunlight as this may affect the clarity of the image. If an alternative location cannot be chosen, it is advisable to use a protective screen that can reflect light. Additionally, if you plan to project onto a wall, it is recommended to purchase reflective paint. Another option is to invest in thick curtains for the windows. Once the location is determined, the next step is to decide on the height at which the screen will be hung. For a standard room with a sofa and chairs, the screen should be mounted at a height of 60-90 cm from the floor. However, if the room will have multiple rows of seating, the projection canvas should be placed higher to ensure a clear view for those sitting in the back rows.

Pro Tip! When selecting the mounting height for your screen, keep in mind the canvas size – if you raise it too high, part of the image may end up on the ceiling.

Next, you’ll need to determine the height and width of your screen in order to position the projector correctly. The recommended throwing distance is typically stated on the projector itself. Many projectors can display an image up to 100 inches diagonally, so if your room allows, you can install a screen of that size.

For a projector

• When placing the projector, it is important to consider the seating location, especially if the device is heavy and large in size. Placing the projector above the seating area can be inconvenient and potentially dangerous.
• Ensure that the projector is located near power outlets to allow easy access to both the power supply and the signal source. This is especially important as there are typically two wires, HDMI and power cord, connected to the projector.

Keep in mind that the image quality may vary depending on the location of the projector. It is recommended to test and determine the optimal position in the room for the best picture quality before final installation.

Just a little addendum! When the projector is installed in close proximity to the screen, the brightness level will go up. Conversely, when the device is placed further away, the clarity and contrast will improve.

Mounting the projector

When you are mounting a projector, there are several crucial factors that you need to take into account. These include the distance at which the projector will be projecting the image, the vertical image offset value, the estimated height at which you plan to install it, among others.

Projection Distance

The term "projection distance" (PD) refers to the distance between the lens and the wall screen. This distance can be determined using the following formula: PR = OD x screen width, where OD represents the projection ratio. To find the value of PA, you should consult the user’s manual. PA can be a single number or multiple numbers, depending on whether the device has an optical ZOOM feature.

For instance, if we have a screen with a width of 254 cm (100 inches) and a PA range of 1.4:1 to 2.8:1, the projection equipment should be placed at a distance of 355.6 cm to 711.2 cm away from the screen. These values can be calculated as follows: 254×1.4=355.6 and 254×2.8=711.2.

On a separate note, you can also use the same formula to determine the screen size if you know the distance between the lens and the wall. In this case, you would need to divide PR by PA.

Therefore, if a device has a projection ratio ranging from 1.4:1 to 2.8:1 and is positioned 5 meters away from the wall, the screen width can vary between 1.8 and 3.6 meters. To determine these values, you can use the following calculations: dividing 5 by 1.4 equals 3.6 and dividing 5 by 2.8 equals 1.8.

Vertical offset

This parameter refers to the elevation of the projection device above the ground, which ensures proper picture display on the screen of specific dimensions. This value can be found in the user manual, expressed in percentages. Therefore, if the desired value is greater than zero, such as +96%, it indicates that the picture will be projected above the lens. The opposite statement is equally valid.

Recommendation! Since projectors are typically mounted upside down on the ceiling, it is important to pay attention to the positive value of the vertical displacement indicator.

Most modern projectors feature vertical lens position correction, which allows you to manually adjust the projected image without altering the physical position of the device. The height of installation for these devices can be estimated initially, as any necessary adjustments can be made after installation. However, if the projector lens is fixed, it is crucial to securely mount the device in the optimal position, determined through experimental calculations (including vertical adjustments) to achieve the most suitable image projection.

Determining the installation height

Once the vertical offset (VS) has been calculated, the user is able to ascertain the appropriate placement height for the projection equipment relative to the center of the screen, using the following formula: h mount = h screen x VS, where h represents the height. As an illustration, if the device has a VS range of -96.3% to +96.3% and a screen height (diagonal 50 inches) of 124.5 cm, it can be positioned above or below the screen center by 119.9 cm.

Selecting a bracket

The selection of the bracket should be based on the specific brand of projection equipment and the layout of the room.

It’s crucial to note that the mount can come in various forms, such as desktop, ceiling, or wall mount, with or without position adjustment capabilities. When making a decision on which bracket to choose, it is important to consider the type, size, and weight of the device, as well as any specific requirements for positioning the projector, be it vertically, horizontally, or at an angle, among other factors.

The projector mount needs to be of excellent quality and dependable. Opting for a cheaper option in order to save money could result in the bracket becoming loose over time, causing the projector to shift its position in relation to the screen. Similarly, homemade mounts should not be used as they can potentially lead to the device falling in the worst-case scenario.

When mounting the projector on a ceiling or wall, it is important to take into account the material of the surface. In certain scenarios, it may be necessary to buy extra mounts, as the ones included in the package might not be appropriate for a specific situation.

Ceiling Mounting

If the user intends to mount the projector on the ceiling, they have to consider the ceiling material as it will affect the installation process. Depending on the type of ceiling – whether it is made of concrete, tensioned, suspended, or plasterboard – the installation steps will vary.

1. In order to install a bracket on a concrete ceiling, proper marking should be done. After that, holes should be punched using a perforator and dowels should be hammered in. Next, the bracket plate should be attached and secured with self-tapping screws. To prevent the wires from being visible and spoiling the appearance of the room, a groove can be made in the ceiling to hide or disguise them with a cable channel.
2. A plasterboard ceiling is perfect for mounting a projector and concealing the wires. If the projector weighs less than 5 kg, the bracket can be fixed directly to the drywall sheets using special dowels-butterflies. For heavier devices, they should be mounted on metal profiles, which are then covered with plasterboard sheets.
3. Hanging ceilings are constructed from retractable panels. To install, simply retract one panel and fasten the bracket to the concrete as previously instructed. Next, create a hole in the retracted panel to accommodate the leg of the holder, and return it to its initial position.

Wall Mounting

Mounting the projector on the wall is essentially the same as mounting it to the ceiling – the same tools are required and the process is identical whether the wall is made of concrete or plasterboard. The only distinction is the selection of a different type of bracket.

When wall mounting, it is crucial to accurately calculate the height, distance from the screen, and mounting angle. If the projector is adjustable vertically or horizontally, any mounting mistakes can be corrected during setup; otherwise, the equipment will need to be repositioned.

Installing the screen and speakers

When selecting a projector, it is recommended to opt for a roll-up screen to ensure convenience and flexibility. With a roll-up screen, you can easily use it whenever necessary, and store it away when not in use. The installation process for a roll-up screen is fairly straightforward:

• Determine the desired mounting location for the screen.
• Drill holes for the dowels to secure the screen.
• Fix the screen base in place using self-tapping screws.
• Add additional holders if needed for added stability.

Pro tip! We suggest starting with the installation of the projector, followed by mounting the screen underneath it.

The acoustics installation process will vary based on the speaker type. You can opt to place them on the floor, use brackets to secure them, or hang them with the help of self-tapping screws, if there are designated holes in the case. For a neat setup, you can hide the speaker wires in a cable duct, underneath a baseboard, behind a suspended ceiling, or other interior elements.

Setting up the projector

Once the projector has been installed, it will require some initial setup. To get started, follow these steps:

• Turn on the projector and dim the lights or close the curtains to minimize brightness.
• Adjust the position of the projected image on the screen using the device’s settings. If no specific settings are available, try repositioning the projector or the projection surface.
• Check and fine-tune the focus to ensure a sharp image.
• Fine-tune the color, contrast, and brightness to achieve the desired display quality.

Tip: If the projector offers automatic setting templates, it is recommended to try them out and select the one that best suits your needs.

With the setup complete, you can now start connecting a signal source and enjoy multimedia content on your projector.

Connecting to devices

In order to link the projector to other devices, it is essential to thoroughly examine both pieces of equipment for the suitable connectors. This process will assist in identifying the necessary cables or adapters for establishing a connection.

Connecting to a computer

When it comes to connecting a PC or laptop, HDMI or VGA connectors are the go-to options, while DVI connectors are not as popular. The key is to locate compatible ports on both devices and establish a direct connection using a cable or an adapter like DVI-HDMI.

Pro tip! If you want higher image quality and the ability to output sound to the projector with connected speakers, it’s best to use an HDMI cable. Keep in mind that the VGA connector does not transmit audio.

Now, let’s talk about selecting the display mode for your screens. To do this, simply press the "Win" + "P" button combination and choose from one of the four available modes:

• "PC only" – the image is only displayed on the computer monitor, and the projector remains inactive;
• "projector only" – only the projection screen is active;
• "duplicate" or "repeat" – the same image is shown on both screens;
• "extend" – the projector screen becomes an extension of the computer screen.

The function "Duplicate screen" is utilized when the projector acts as an interactive whiteboard for presentations in educational institutions or workplaces. On the other hand, the "Extend" mode allows the simultaneous execution of multiple tasks. To illustrate, one can project a movie onto a large screen using a home projector and simultaneously use their laptop or PC for other activities.

TV connection

If you don’t want to watch broadcast programs on an outdated electron-beam TV, you can connect the device to a projector to use it as a signal source.

By the way! If your TV receiver has RCA, SCARD, or S-Video video outputs labeled as OUT, you can configure the setup to project TV channels. However, it’s worth noting that such connectors are quite uncommon on modern LCD TV panels.

In order to connect the projector to a TV without a computer, it is necessary to establish a connection between the corresponding Out connectors on the TV receiver and the In connectors on the projector using the appropriate cable. If needed, adapters may be utilized, although it should be noted that signal quality may be compromised in such cases. For instance, if the TV has an AVI Out connector but the projector does not have a corresponding input, an AVI-SCARD cable or adapter can be used. Following this, both devices should be turned on and the projector should be set to playback the signal from the connector where the TV receiver is connected. This will enable viewing TV programs through the projector.

Connecting to a set-top box

There is another option for connecting a projector to a device – a satellite set-top box or a digital DVB-T2 receiver. Establishing the connection is quite straightforward – you just need to examine the equipment, find the matching connectors (preferably HDMI), purchase the required cable, and connect the devices using it. After that, power on the equipment and select the corresponding input on the projector for the set-top box.

Connecting to a phone

If the projector features an MHL-labeled HDMI connector, it offers the capability to connect a smartphone or tablet to the device. This facilitates the transfer of images from a smaller mobile display to a larger wall screen. To establish this connection, users will need to acquire both an HDMI cable and a specialized MHL adapter. The adapter, which is connected to the phone via micro USB on one end and to the projector via HDMI on the other, provides the advantage of being able to be used with a power source. This power source is necessary as the typical adapter may not supply enough power to convert and transmit the signal in high quality.

Therefore, when purchasing a projector for your car, apartment, or office, it is crucial to recognize that achieving a superior image quality from this device is contingent upon proper installation, configuration, and connection to the signal source. Additionally, accurately determining the device’s placement and correctly installing it on the wall or ceiling are of utmost importance.
