Put Things Up on a Screen With an LED Projector
Whether you're getting ready for a business presentation or want to showcase pictures or videos at home, having an LED projector can be useful. They can let you enlarge your images so that many people can enjoy them. There are some variances in the projectors available on eBay, which are available in new or used conditions.
What is their connectivity like?
There are many connectivity features included in projectors. You can find:
- Wireless versions - Wireless LED projectors come with an internal Wi-Fi card. This lets them connect to an existing wireless network and accept information from nearby computers or mobile devices. This is helpful if you have a room layout where you don't want anyone to get tangled up with wires. Sometimes, the use of a wireless unit can require the use of the manufacturer's app.
- Plug-and-play versions - These rely on a USB cable to connect a device. Rather than using VGA keys and adjusting settings on a computer, the use of a USB cable is quite convenient. In many cases, you can plug in a USB thumb drive and the projector will be able to display the saved images.
- HDMI ports - If you have a media player, you may be able to use HDMI cables to connect to a projector with the right ports. Then, you may be able to stream content, play CDs, and watch Blu-ray discs.
- Display ports - These ports can be used to connect with many types of cameras, DVD players, and computers. They can sometimes be backward-adapted to work with VGA and DVI cords.
What brightness do you need?
Brightness is measured in lumens. The ideal amount you may need depends on the size of your room, the level of ambient light present when using the projector, and the type of screen you'll be using. A smaller, almost mini, version of an LED projector may only have around 500 lumens, and larger, more advanced projectors may have 3000 lumens. Fewer lumens may be sufficient if you're using the projector in a small, dark room for home theater purposes. One used in a large conference room may need to be brighter.
Are there other factors to consider?
When looking at projectors on eBay, you can also think about portability. Having a device that you can move from room to room can come in handy if you're sharing it at work. In contrast, a home theater projector will likely not have to be moved frequently.
