![]() Don't pay too much attention to the weight if you are not carrying the projector to the office every day. This is annoying if you have to constantly adjust the projector again. Without screwing them down using tripods or something similar, lightweight portable projectors can easily topple over due to the weight of the cables. The reason behind this? If projectors are too light, it can be challenging to set them up properly at times. Unfortunately, a carrying case is sold separately from the Freestyle. While not all sizes would suit you, we do think that it is better to pay more attention to the weight. Manufacturers usually state these in the technical specifications, and you can also find the dimensions in the table at the beginning of this buying guide. If you bring your portable projector along, you should pay attention to its size and weight. The same applies to autofocus, which all modern projectors should carry. This function is really practical and can usually be readjusted later if required. The projector then uses these sensors to independently measure how it needs to adjust the image so that the finished product is displayed in an undistorted manner on the screen or wall. Models such as the Samsung Freestyle (for review) can be set up at very flexible angles to the wall. If you cannot set up your projector at a different distance from the wall, you can normally use a digital zoom, but this reduces the display quality.Ī major advantage of modern projectors, however, is the auto-locking function including keystone correction. Without optical zoom (which works similarly to a camera lens), the image size changes depending on the distance between the projector and the wall. Speaking of optical zoom, you will normally have to live without it when buying a portable projector. However, pay attention to the specifications such as the resolution, brightness, and contrast ratio to be able to assess the image quality before buying. In addition, manufacturers can also enable optical zoom and lens shift is possible if required.Īs manufacturers focus on compact chassis for portable projectors, DLP technology can be found in most devices. This takes up more space but enables better color values, higher contrasts, and quieter operation. This is because the light is split between several chips via mirrors and a prism before being combined to form the final image. LCD projectors have none of these disadvantages, but the technology is far more complex. The disadvantages include black levels that are normally not as well-defined as other technologies, and these projectors tend to be noisier with the lack of lens shift or zoom capability. DLP projectors generally have a smaller case, and this technology is also relatively affordable. For DLP projectors, the light beam from the source is beamed through a color filter onto a DMD chip.Ĭountless small mirrors produce the brightness values, which are magnified via the projection lens to produce the final image. Short-throw projectors in a portable form factor are extremely rare, so we will exclude these models from the equation. In terms of projection technology, a rough distinction can be made between LCD and DLP. The rule of thumb is this: projectors that are rated 5,000 lumens or fewer are best used only in the evening, at night, or in a very dark room. While lumens refer to the luminosity of the light source itself, ANSI lumens are measured off a reflective surface. What is important in every projector is the luminosity, which manufacturers specify as lumens or ANSI lumens. Most projectors of yore normally came with a built-in light source, with manufacturers relying on LED technology or laser systems. Be sure to check back with us regularly! What you need to look out for when buying a portable projector Projector and technologyĪt the beginning of this article, we briefly talked about old projectors. ![]() Over the next few weeks, we will check out what we think are the best portable projectors and summarize our impressions for you in detailed reviews. In this overview, we will tell you which models we found interesting and what you should look out for when buying a portable projector.
