I bought the Powerlite 1761W for power point presentations to clients and referral sources in conference rooms and class rooms. It is amazingly light and easy to carry, set up and pack up. It produces a very crisp, HD image. My team is totally satisfied and even the least techy members use it with confidence. We do not mess with the focus adjustments, it adjusts perfectly on its own. Three surprises. One, the carry bag is not sturdy looking and is not quite big enough to hold the projector, cables and accessories. I am surprised Epson put its logo on a bag that is so poorly matched to the product. Two, although touted as wireless, it has no wireless connection to my laptop (I was thinking blue tooth), only a wireless connection to my office LAN, not what I expected from reading the product description. Three, although it came with USB and VGA cables my laptop has no VGA port and the USB cable produced a "No signal" message, so I called tech support. I learned the USB cable is not for a laptop connection and I should get a HDMI cable (which did not come with the projector). Tech support told me to just disregard all of the written instructions that come with the projector and let the product run itself. They were right. Tech support was very accessible and responsive and supportive, and the HDMI cable totally worked and made me very happy with the projector.
