What to look for when choosing?
When choosing a projector for watching movies at home, you need to pay attention:
Diagonal image. The diagonal should be more than 1 m., Most often it is limited by the size of the wall on which the image is projected.
Resolution. Often on small portable projectors it’s 800 x 480 pixels, which is not suitable for watching movies at home.
For home use, HD resolution, or better yet, Full HD or 4K resolution.
Keystone Correction. Thanks to the correction, the projector can be installed near the wall or side and get a high-quality rectangular image.
Contrast. This parameter is indicated in the instructions, however, it is better to read user reviews.
Connection Method:
- independent playback from a memory card;
- On portable devices, the Android operating system is often installed;
- large devices rarely install an operating system; you can connect a video camera, game console or TV set-top box to them.
IMPORTANT. It is better to make sure that you have the necessary audio outputs, the number and types of connectors.
Installation method:
- suspension;
- Mounting on a tripod (requires appropriate socket).
With a high resolution matrix in case of 3D support, you can watch movies in 3D. Points are sold separately.
The fan cooling the lamp is noisy in large projectors. Therefore, for a home, it is better to choose a device with a noise level of up to 20-25 dB.
Devices projecting an image on a wall have their own advantages (less eye strain, small size and affordable compared to large TVs price) and disadvantages (image quality depends on the darkness in the room, a small selection of types of devices, limited lamp life, the need to observe the distance to the screen). When choosing a suitable device, you need to proceed from its technical characteristics, the purpose of the acquisition, the size of the room, price and personal preferences.
