Epson PowerLite 1775W
Mobile Presentation Projector
February 3, 2011
If you were going to offer a new 3,000-lumen 1200x800 mobile presentation projector to a market that has seen just about everything, which feature would you make sure to include? Versatility? Convenience? Networking? Wireless presentation? You could make a case for any of them, but Epson included them all in their new, slim, 3.8 lb., PowerLite 1775W, priced at $1,199. The 1775W has a full complement of analog and digital inputs and can handle flash drives and USB-compatible devices such as cameras and cellphones. But that is not the heart of the matter.
The 1775W really hits its stride when your presentation calls for fast start and stop times, easy image setup, cable free projection, and compression software that puts your Powerpoint presentation on a thumb drive so you can leave your laptop in the car. Features like powered focus and automatic vertical and horizontal keystone correction make life easy. The built-in wireless LAN hardware even makes switching laptops during a presentation a breeze. A road warrior will drool over this projector . . . it is light, bright, and packed with convenience features that support all sorts of presentation environments. It is also a natural for brainstorming sessions where multiple computers will be connected for short durations.
Brightness and Uniformity: The 1775W exceeded its brightness rating with 3,110 ANSI lumens in Dynamic mode. Presentation mode delivered 2,485 lumens and Theater, Photo, and sRGB all put up 2,240 lumens. Eco mode dropped brightness by 45% which is more than the usual reduction, but with that came a 10dB reduction in fan noise. Uniformity was a very respectable 84% with the left side of the image slightly brighter than the right.
Image Size and Position: The centerline of the lens is 2.2" above the bottom of the image for a 100" image at a 16:9 aspect ratio. This is a good offset for tabletop and ceiling mounting, but you may need to make further adjustments by extending the front elevator foot of the projector. The projector can be tilted by unscrewing either rear foot to correct any horizontal leveling issues.
Compatibility: Computer resolutions from 640x480 to 1680x1050 are scaled to fit the 1775W's 1280 x 800 native resolution. Video signals from 480i to 1080p are also accommodated.
Preset modes: There are five color modes (Presentation, Dynamic, Theater, Sports, and sRGB) as well as blackboard and whiteboard settings. There is also one customizable setting for storing your favorite image adjustments.
On-Screen Menus: The 1775W's seven on-screen menus are pretty straightforward with minimal layering. Navigation is easy, and when image adjustments like brightness and contrast are made, the menu conveniently collapses to a single line at the bottom of the image.
Digital Input: The 1775W has an HDMI input that handles inputs from certain laptops and most DVD players.
Placement Flexibility: The 1.2:1 zoom capability gives you modest projection distance variation for a particular image size. For example, to project a 100" diagonal image in a 16:9 format, the projector is about 100" from the screen and can shift about ±10" and maintain that image diagonal.
Auto Source Search: On power up, the 1775W searches all inputs and selects the first active connection it finds. When the Source key is pushed on the remote, it begins searching and selects the next connection it detects. This is convenient when you have multiple sources connected but cannot recall which inputs are active . . . the 1775W will find them for you.
Network Connections and Management: Epson supports a remote monitoring application called Easy MP which uses a Simple Network Management Protocol (SNMP) to communicate with compatible computers and projectors. It can remotely monitor projector status such as lamp condition and internal temperature and alert maintenance personnel to possible problems.
