Minimum of 4000 hours of lamp life — has eco options to extend this 10000:1 contrast ratio to bring out colors and get darker darks 1080p resolution supporting screens from 40-300 ...

The main problem with pocket-size projectors is that they mostly rely on wireless connection rather than typical interfaces. What is more, low resolution can make subtitles unreadable. If we are talking about mini projectors, I can suggest ZeleSouris UC40. Pros: suit for home video playing relatively small (20.1 x 15.3 x 6.7 cm; 998 g) affordable price (~...

In order to cover Windows, Android, Mac OS-X, and iOS, you'll need a two part solution. As you've already discovered, Miracast is a wireless display standard. It is effectively HDMI-over-wireless. The Wi-Fi Alliance maintains a list of compatible products. Note that it can be called different things by different vendors; Samsung calls it "AllShare Cast" for ...

First of all, I'd like to start by saying that the throw ratio for this projector = 0.133 is very good. If you put a different lens on it, for example that can focus when 70cm away, then your image would be 210" wide. In other words, you can get a larger image size simply by moving the projector farther from the wall, provided you can find a lens that can ...

You've referenced a speed, which is likely not going to be a problem, depending on the driving computer. A Raspberry Pi may not be powerful enough, although the RPi4 seems promising. You've not referenced resolution, which may be more challenging. The projection part, especially if you need only one color, is partly complete in the form of LCD panels for ...

You can more easily solve your problem if you divide it in 2 devices. Get any common projector that solves your presentation needs, but with an HDMI input. With that get an Intel compute stick or a raspberry pi with Wi-Fi, put your OS on that and get remmina running from the network.

This one is under budget, and meets all of your other criteria. Seems like a solid little piece of hardware, I might pick one up... It sounds like your travelling alot. I would consider getting a small bit of projector cloth and 4 push pins. I doubt hotel staff would see the pin holes, and it would make your experience with any projector better. You can ...

I finally bought 2 of them http://www.projectorcentral.com/parts_compare.cfm?pid_1=7456&pid_2=7436 Well to be exact, I bought one. And then realize that the second one is better for me. So I exchange the first one with the second one. Acer H6510BD http://www.projectorcentral.com/Acer-H6510BD.htm is the way to go. However, my room has a width of 3.2 m ...

The yoga tab 3's 480p screen would be a pain to watch on. A 480p screen at 10" size is already terrible (80 ppi). The 480p screen would be ok for stuff like video conferencing or a presentation but would be very terrible for movies. The ZTE SPro 2 has a much better quality projector (720p). This will have the same pixel density as the yoga tab 3 when at 20" (...
