Here are some features and specifications to consider when buying a smart projector. They can help buyers choose the right smart projector based on their requirements.

1. Resolution
Like all other projectors, the main hardware specification to consider for smart projectors is their resolution. Most models have either HD (720p) resolution or Full HD (1080p). Therefore, the ideal and most popular projector resolution today is 1080p. Images projected at this resolution maintain sufficient sharpness for large screens of 100 to 120 inches. Viewers will be able to enjoy the film and video with rich detail. Many smart projectors have high definition (720p) resolution, especially in portable models. Still being able to watch movies on a big screen offers good image quality. Users on a budget can consider a 720p smart projector.
2. Brightness
Brightness levels are an important specification to consider when buying a smart projector. Note, however, that brightness is expressed in ANSI lumens, typically between 200 and 3,000 lumens. The brightness level of the projector determines how visible the projected image is in different ambient light. Rooms with more ambient light will require equipment with higher brightness levels. A projector with a brightness rating of 800 ANSI lumens may look sharp in a dark room, but blur in areas with moderate ambient light. Therefore, the purchaser must choose a smart projector whose brightness level is appropriate for the environment in which they are installed. In general, projectors with brightness levels in the 1,600 to 2,000 ANSI lumen range are suitable for most scenarios. Users of smart projectors with approximately 800 ANSI stream brightness levels can control ambient light to improve image visibility. Smart projectors typically feature LED light sources, and premium models are equipped with laser engines.
3. Projection distance/projection ratio
Projection distance is another important specification to check in smart projectors. Models with ultra-short throw ratios can project large images a few inches from the screen (typically 80 to 100 inches from the screen). They take up very little space and can be installed almost anywhere. Smart projectors with short throw ratios are also available and must be installed 3 to 6 feet away from the screen to produce large images. Buyers can choose the model that the projection ratio is appropriate for their installation scenario.

4. Same-screen projection
Simultaneous projection is a convenient feature in smart projectors. Allows users to project content from their smartphones onto a large screen through a projector. If a wireless network is not available, simultaneous projection can be useful in smart projectors because content can be streamed from a smartphone or tablet.

5. Autofocus
Buyers must consider the autofocus and correction features in smart projectors. Most modern models come with autofocus, which guarantees a clear image. In addition, trapezoidal distortion correction is another feature required for smart projectors. It can be used to correct disproportionate images due to improper alignment of the projector and screen. Ideally, buyers must consider projectors that support vertical and horizontal trapezoidal distortion correction, but cheaper models may only have the former. Many projectors also have an automatic keystone distortion correction function that makes image adjustment easy.
6. Interface options
You must also consider the interfaces available on the smart projector. It should have a sufficient number of ports to meet the user's requirements. The smart projector must have at least one HDMI port (preferably 2.0), a 3.5 mm audio output jack, a USB port, and a LAN port for Ethernet. Most devices will support 2.4GHz Wi-Fi, but models with dual-band Wi-Fi (2.4GHz and 5GHz) are even better. If wired mirroring is required, you should have a USB-C port that provides support for screen sharing.

7. Speaker quality
Since smart projectors come with integrated speakers, buyers may need to pay attention to their audio quality. Some models of speakers may not be audible from a few feet away, while others may be filled with audio in a medium-sized room. Buyers must choose a model with speakers that generate enough volume for their usage scenario.
8. Mobile portability
Portability is an important feature for smart projectors to consider. It has a compact, lightweight design and takes up minimal space in the bag. Users can take a business trip demo or even go out on a trip to entertain and watch movies. There is also a built-in lithium battery that allows the projector to be used without a power source. If you want to take your device with you, consider using a portable smart projector, preferably with a built-in lithium battery.
