Like the PowerLite 1930 and PowerLite 1940W, the Epson 1945W is aimed at users requiring a projector for a business, educational setting or house of worship. It is nearly identical to the 1940W, with the exception of one important feature.

Dimensions

The Epson PowerLite 1945W is a 3LCD projector. It measures 14.8 inches wide by 10.7 inches in diameter by 3.6 inches high when the feet are not taken into consideration.

This model weighs in at 8.5 pounds. It has the same dimensions and weight as both the PowerLite 1930 and 1940W.

Display Specs

The native aspect ratio for the 1945W is listed at 16:10, which means it is ideal for widescreen viewing. The native resolution is WXGA (1280 x 800).

The contrast ratio for this model is 3,000:1, which, again, is the same as the other two models in the line.

The throw ratio range is listed as 1.38 (zoom: wide) - 2.24 (zoom: tele). The 1945W can project from a distance of 29 inches to 280 inches, which is slightly less than the 1930 (that model goes up to 300 inches).

Light output is listed at 4,200 lumens for both color and white light. Color and white light are measured using the IDMS 15.4 and ISO 21118 standards, respectively, according to Epson. These figures are the same as the the other two models.

The projector uses a 245-watt UHE E-TORL lamp (Epson's own lamp technology).

The company says this lamp lasts up to 4,000 hours in ECO Mode and 2,500 in Normal Mode. The lamp life is significantly less than many of the newer PowerLite models, especially those with lower lumen counts. This is not a surprise -- higher lumen output requires more lamp power -- but it's still an important concern.

When purchasing a projector, the lamp lifetime is an important concern because replacing the lamp can be pricey (this is no ordinary light bulb). Replacement lamps can run the gamut depending on the type you need, but expect to spend around $100 for one.

Lamp life can also vary based on the type of viewing modes used and in what type of setting it's used. As the company points out in its product literature, the lamp brightness will decrease over time.

Audio Specs

Like the other two models, the PowerLite 1945W comes with one 10-watt speaker. This is certainly more robust than many other Epson projector models geared toward small businesses, and it's designed to be suitable for use in a large room.

The fan noise is 29 dB in ECO Mode and 37 dB in Normal Mode, according to Epson. This is about standard for the company's PowerLite models.

Wireless Capabilities

This is where the PowerLite 1945W really stands out from the 1940W. This model does include built-in Wi-Fi, allowing you to take full advantage of Epson's iProjection app. This app lets you display and control content from your projector using an iPhone, iPad or iPod Touch. For example, if you want to display a photo or website on your iPhone to the projection screen, you just need to pair the projector with the app -- never mind USB cables or even USB sticks.

If you don't have one of these Apple devices, you can also control the projector using a computer browser if the projector is connected to a network. Epson says you don't need to download any software and that it works with both PCs and Macs.

The PowerLite 1945W can also be used with the following remote control and management tools: EasyMP Monitor, AMX Duet and Device Discovery, Crestron Integrated Partner and RoomView, and PJLink.

Inputs

There are several inputs: one HDMI, one DisplayPort, one video RCA, two VGA D-sub 15-pin (computer input), one RJ-45 network port, one RS-232C serial port, one monitor-out D-sub 15-pin, one USB Type A, and one USB Type B.

If you're not sure of the differences between Type A and Type B USB ports, here is a quick and dirty lesson on the difference between the two inputs: Type A looks like a rectangle and is the kind that you'll use with a memory stick (also called a portable flash drive). The shape of Type B can vary, but it often looks like a square and is used for connecting other computer peripherals.

Because the PowerLite 1945W does have the Type A connector, you will not be required to use a computer for presentations. You can store your files on a memory stick or hard drive, connect it to the projector, and carry on.

Power

The power consumption for the 1945W is listed at 311 watts in Normal Mode, which is slightly higher than the 1930 but the same as the 1940W.

Security

Like most, if not all, Epson projectors, this one comes with Kensington's lock provision (a commonly found hole meant for use with Kensington's popular locking systems). It also comes with a password proection sticker.

Lens

The lens has an optical zoom. This article from About.com's Camcorder site explains the differences between optical and digital zooms.

The zoom ratio is listed at 1.0 - 1.6. This is the same as the others.

Warranty

A two-year limited warranty is included for the projector. The lamp is under a 90-day warranty, which is typical The projector is also covered under Epson's Road Service Program, which promises to overnight ship a replacement projector -- for free -- if something is wrong with yours. Fine print aside, this sounds like a good promise for road warriors. There is the option to purchase additional extended-service plans.

What You Get

Included in the box: projector, power cable, component-to-VGA cable, remote control with batteries, the software and user manual CDs.

The remote can also be used at a distance of up to 11.5, which is a few feet shorter than most Epson projectors. The remote features the following functions: Color mode, brightness, contrast, tint, color saturation, sharpness, input signal, sync, source search, and Split Screen. This last feature enables users to display content from two different sources at the same time.

Beyond just Split Screen, the PowerLite 1945W also features Epson's Multi-PC Collaboration tool, so you can display up to four computer screens at the same time. More screens can also be added and put on standby mode.

This PowerLite 1945W boasts automatic vertical keystone correction, as well as a "Quick Corner" technology that lets you adjust any corner of an image independently.

It also has built-in Closed Captioning, and Epson has included several video-enhancement processing technologies that are meant to improve video performance, such as Faroudja DCDi Cinema.   

Price

The PowerLite 1945W has a $1,699 MSRP, which is $400 more than the 1945W.
