Calculate projection distance correctly
The lens of a projector is crucial for positioning and adjusting the image size because it affects the projection distance. Most projectors have a fixed lens that requires a certain distance from the screen. However, most projectors with a fixed lens offer a flexible projection ratio that allows the distance between the projector and the screen to be changed.
To calculate the projection distance yourself
The projection ratio can be used to determine distances and image widths. The ratio indicates the distance at which the projector must be set up to obtain a 1 m wide projection.
Assuming that the optics of a projector offer a projection ratio of 1.5 - 1.66:1, a distance of 1.5 - 1.66 m is needed for 1 m image width.
To achieve an image width of 2 m, we calculate 2 × 1.66 = 3.32. This value corresponds to the greatest distance to the wall in metres. Then we calculate 2 × 1.5 = 3. This value corresponds to the smallest distance between the projector and the screen. So we can vary the distance of the projector between 3 and 3.32 metres to get an image width of 2 metres.
Install projection screen
Since a projector screen takes up the most space, we recommend installing it first. It is best to get help to install it in the desired location without any problems. The installation of a projector, on the other hand, can be done on your own.
Install projector
The alignment of the projector depends strongly on the optics and the projection technology used. A projector must therefore always be aligned individually, especially if it is to be suspended from the ceiling. The so-called offset value plays a central role here. This indicates the percentage vertical offset of the projected light cone from the centre of the image.
For example, an offset value of 50 per cent means that a projector must be aligned with the bottom edge of the screen for a straight projection.
An offset value of 0 percent means that the projector is level with the centre of the screen, which is usually the case with projectors with good lens shift. For ceiling mounting, this offset must be mirrored vertically downwards accordingly, especially if the projector is to be hung there.
To determine the offset yourself
Place the projector on the floor at a distance from the wall that is necessary for the desired picture size. Now measure the distance from the floor to the bottom edge of the picture with a folding rule. You have already determined the vertical offset. If you are using a projector with good lens shift properties, the offset is irrelevant. The lens shift compensates for a large part of the image height.
Mounting the Projector Ceiling Mount
For high ceilings, we recommend height-adjustable ceiling mounts for projectors. With these ceiling mounts, you can flexibly adjust the vertical distance to the ceiling.
With a usual ceiling height of approx. 2.4 metres and an image start (upper edge) at a height of approx. 2.2 metres, a rigid ceiling mount with a distance of 15 cm can also be used for an LCD projector. A DLP projector can be hung a little higher or the screen a little lower.
Keep one or two spirit levels handy for adjusting the projector. This way you can determine and optimally adjust the tilt to the front and to the side at the same time.
Align and adjust image
As soon as the projector is mounted on the ceiling, it can be connected. In addition to the power cable supplied, you will need cables for image and sound transmission from a playback device such as a Blu-ray player or a notebook. Usually, an HDMI cable is used for this purpose. If you are not sure which connections you want to use, our buying guide on connecting a projector will help you.
Vertical and horizontal lens shift can only be combined to a limited extent. When using horizontal and vertical lens shift at the same time, both limit each other and the maximum values cannot be reached. When trying to set the maximum values, the lens therefore follows the shape of a stop sign rather than a rectangle.
The lens shift value is always given from the centre of the lens. This means that with a vertical lens shift of e.g. +/-50%, the image can be shifted up or down by 50% of the image height from the centre of the image. The same applies to the horizontal lens shift.
There are several ways to adjust the keystone correction. The classic method is to press a button on the surface of the projector. A little more comfortable is the adjustment by remote control.
Colour and image calibration
projectors usually have a setup menu for various colour and picture settings. Although the menus differ visually from manufacturer to manufacturer, they basically offer similar or comparable settings.
Classic colour settings for home cinema are e.g. "Cinema". For business projectors used in conference or meeting rooms, we recommend the colour setting "Presentation" or a comparable setting. This reduces colour fidelity but offers high brightness. Optimal for bright rooms.
On the other hand, avoid the picture setting "Bright". Here you achieve maximum brightness, but at the expense of picture quality. If you want to calibrate yourself, this will not reach the level of a professional calibration, but it can improve the picture. Use test images for this purpose. You can find a suitable provider via Google search.
High End Colour Calibration
In addition to the default settings, some projectors offer colour management settings. Depending on the model, calibration menus according to the ISF (Imaging Science Foundation) or ISF ccc standard are available. These allow you to save colour profiles after the projector has been calibrated by a certified body. Compared to the conventional mode, a calibrated projector gives you a significantly better picture quality.
Which is better: standard or eco mode?
The setting of the lamp influences the picture quality. In most cases, you can choose between normal and eco mode. In normal mode, the full brightness is achieved. For bright rooms, this mode is therefore a must. If it is possible to darken the room, Eco mode is a good alternative. The light output is reduced and the picture appears somewhat darker. This has a positive effect on the image contrast and extends the life of the projector lamp.
Controlling the projector: via remote control, AirPlay, Miracast, app or Alexa
