Epson PowerLite Pro G5450WUNL
WUXGA LCD Presentation Projector
August 5, 2011
The Epson PowerLite Pro G5450WUNL is a 1920x1200, or WUXGA, projector that sets a new standard for high-resolution projection. It combines a maximum 4,000 lumen light output with the highest resolution available in a presentation projector, then adds a pile of useful features ranging from wireless projection and management to interchangeable lenses and a DICOM simulation mode for medical training applications. With H/V lens shift and a connection panel that incorporates every port under the sun, the G5450WUNL sells for $2600 without a lens or $4000 with the standard 1.8:1 zoom, making it one of the least expensive WUXGA projectors on the market.
The real defining feature of the G5450WUNL (henceforth referred to as the G5450) is its high resolution of 1920 by 1200. WUXGA is not the highest resolution available in a projector, but while 2K and 4K resolution projectors are available, these high-end models cost many times more than the G5450. So consider WUXGA the highest resolution available under $5,000. This resolution takes 1080p and expands it to a 16:10 aspect ratio, making it a perfect match for a high-resolution computer instead of an HD video source.
High-resolution projectors like the G5450 have a number of applications in business and beyond. Schematics and other highly detailed graphic images are best displayed on a high-resolution projector, as are complex spreadsheets or photographs. In fact, with the G5450's color performance being as good as it is, photography clubs may want to invest in one for group showings.
Art history and appreciation classes could be improved with the addition of higher-resolution views of the art in question, and the G5450's color performance is of benefit here as well. The projector's DICOM simulation mode, meant to mimic the performance of medical instrumentation, is of use in medical training and testing applications where the cost of a full DICOM system is not an option.
The G5450 has interchangeable lenses, but the standard 1.8:1 lens will be sufficient for many people. This lens can produce a 120" diagonal 16:10 image from 10' 11" to 19' 7". However, should the standard lens not suit your needs, the others probably will. In total, including all of the lenses, the G5450 can project a 120" diagonal image from anywhere between 10' 11" and 59' 2". There is also a fixed focal length option for rear projection. Manual horizontal and vertical lens shift is available, with 2.25 picture heights of total vertical range and a more limited 0.25 picture widths, which makes rear shelf mounting an option in addition to the more conventional ceiling and table mounts. Since the lens shift range is biased towards one side (you can place the image well below the lens centerline, but only slightly above it), ceiling mounts might require a drop tube. Table placement can be difficult since the G5450 has a powerful fan and produces quite a bit of heat, so any members of the audience sitting forward of the projector may feel uncomfortably warm.
