Epson PowerLite 1775W Projector Review
Great performance and wonderful features in an impressively compact package.
Like all projectors, the Epson PowerLite 1775W has a number of display modes. Some modes maximize brightness while sacrificing color performance, while others do the reverse. If you can find a dark room, you should always aim for maximizing color performance. Boardrooms and sunny classrooms require a different approach. We chose four different modes to test. You can see the results below. There's a huge difference between the color-friendly Theater mode and the color-sacrificing Dynamic mode.
Peak Brightness Comparison
Many projectors and some TVs (plasmas, typically) have a hard time maintaining a consistent black level. If there's a lot of black area on the screen, the black levels are deep. If there's only a little black surrounded by a lot of bright white, the black level gets brighter. The Epson PowerLite 1775W very clearly had a hard time here.
The uniformity of the brightness is going to vary depending on the projector's angle and distance to the screen, but suffice it to say that no projector is perfectly uniform. Here's a graph showing the luminance variations in our particular set-up. The corners fell off pretty steeply, but the side-to-side uniformity was good.
The greyscale gamma indicates how well a projector transitions from black to white. The Epson PowerLite 1775W's performance is good, but not great. Look at the chart below. We're looking for a smooth line that transitions from lower left to upper right. The Epson PowerLite 1775W's response curve shows no bumps or hiccups, so we don't expect to see any banding. However, the curve is nearly horizontal for a stretch in the lower left portion of the graph, which represents the shadow details. Don't expect to see much detail here.
