Wireless Projector

Bigger is not necessarily better, but in this case the results are stunning. Projectors always fascinated me, partly job related but mostly the experience of having your own movie theater viewing. Up to a couple of years ago it was somewhat cost prohibitive to own your own quality projector. The cheaper once had not enough lumen1 to make make it worthwhile getting one. Revisiting that subject recently, mostly that I needed one for presentations. Epson came out with a model which had enough light emission for a presentation in a lit room, plus it is wireless. The following I copied from the site directly:
The Espon EX5220 has:
    Color Brightness: 3000 lumens
    White Brightness: 3000 lumens
  • Wireless connection to your laptop and mobile device — connect directly to your computer, smartphone or tablet, without wires. Wireless LAN included.
  • Simple Setup Suite — Epson offers a host of innovative features that ensure flexible placement and quick setup in any room
  • Easy image adjustments — position your projector almost anywhere and still get a correctly proportioned image with auto vertical correction and Easy-slide horizontal image correction.
  • USB Plug 'n Play instant setup — use the included USB cable to instantly project content. View your projected presentation on the screen and your computer simultaneously.
  • Convenient lens control — optimize the image size whether your projector is close to the screen or far away, with the zoom lens.
  • HDMI connectivity — Get both audio and brilliant HD video content with just one cable. The EX Series is compatible with the latest laptops, Blu-ray® and media players.
  • Instant Off®/On — quickly power down the projector, pack up and go
  • Sleep Mode (A/V Mute) — pause your presentation without turning the projector off
  • Direct Power Off/On — control your projector with the flip of a switch
It simply has all the connectivity, plus it allows connections from either a smartphone or tablet. The setup was straight forward with one exception: the wireless connection. Contrary to their wireless printer, the wireless setup did not connect to the network right away, despite the values being correct. It took several tries to get it to the point where the projector recognized the network. Once it was in the network the projector delivered as promised. The IPhone, IPad, computer, media server connection all showed a crisp clear image. Presentations were easily controlled by the remote or via touch from connected devices. Even the audio had decent quality, nothing compared to a surround system of course. But audio in a presentation should be from the presenter in most cases anyway and the presentation should speak for itself which is another topic all together.

1The lumen (symbol: lm) is the SI derived unit of luminous flux, a measure of the total "amount" of visible light emitted by a source to make make it worthwhile getting one.
