Other pico projectors use this small space for streaming apps – these projectors allow you to download and install your favorite apps, such as those for Netflix, HBO or ESPN. That way, you don’t have to worry about the battery dying during your favorite movie scene. Average projectors have batteries that last between one and two hours while high-end models can go for up to 2.5 hours. Projectors also require you to focus the picture that’s projecting. It gives you HD resolution and projects the picture of sharp and clear pixels to provide an excellent experience. It works well in brightly lit rooms (though better in darkened ones with the curtains drawn) and has a crisp 1080p picture which looks good whether you’re watching big movies or intimate TV shows. But, if you have interference from ambient light sources, it’s going to make the video image not look that good if you are using a projector with a low lumen rating. A USB port and a microSD slot are nice to have as well, as they allow you to access content from a wider variety of sources. That LED to the right is really your best indicator of which USB-C port is Thunderbolt-enabled (the right) and which is a standard USB-C port (the left).
None of the projectors we tested had every single port option we consider to be important, so make sure you know what connection options you need before buying your mini projector. Along with standards like HDMI, business-friendly mini projectors feature options like VGA ports and audio output. Once you’ve chosen your mini projector and have it set up in your home theater – or your car, bedroom or tent – the next task is to find something to watch. This is handy if you have your work presentation stored online or if you just want to have a Netflix marathon while you’re camping by the beach. They are controlled with a handy remote, which can adjust their brightness, pattern, and speed. Ceiling-mounted, front-projection units are used in the most elaborate home theaters and display the largest images possible. A lot of home projectors now use the 4K UHD format and there is an increasing amount of 4K UHD content available, either streamed or off disk. 13. Nerd out with floppy disk coasters.
Good projectors should have a keystone adjustment option, which automatically “straightens” the image out if you’re projecting to a display at an awkward angle. S Pen can perform, such as zooming in or out and switching between different camera modes. You can damage your eyes by staring at the sun. Most mini projectors come with 3.5mm audio output or Bluetooth connectivity, so they can connect to external speakers for better sound quality. Some more expensive projectors will also have WiFi and Bluetooth connectivity options, so you can wireless connect them to devices like smartphones and tablets. Sync your phone’s Bluetooth to play music from the device. However, the same scene on a device with a high contrast ratio will show you different gradients of black, meaning you’ll see more detail. If you’re moving between offices or businesses, it’s not guaranteed that you’ll be connecting to a device with modern inputs and outputs. If you’re constantly moving the projector around – on vacation, for instance – you’ll need to adjust each time you move it.
If you plan to frequently move your projector around your home or office, make sure you know the projector’s throw specifications. If you plan on using yours heavily, we recommend keeping it plugged into a power source like a wall socket or portable battery brick. The ideal throw ratio depends on where you plan to use the projector. For example, if you’re watching a movie and there’s a dark scene at night or in a dim basement, on a projector with a low contrast ratio it’ll just look all black, without much detail. The throw ratio determines screen size range and is calculated by dividing how far the projector is from the screen by the width of the projected image. While the Sony VPL-VW675ES wins it when it comes to the sheer number of features and image quality, we now recognize in hindsight that it probably shouldn’t be compared to the other projectors on this list because of the massive gulf in price. Most low-resolution projectors can still display HD content like Blu-ray movies and video games, but because the image has to be downsized, image quality generally steps back. Luckily, you can watch anything on your mini projector as long as it’s hooked up properly, including movies and shows from the best TV streaming services (though you’ll obviously need to be somewhere with a reliable internet connection for that).
