The Optoma TX542-3D is a well-balanced projector that features a very sharp picture and great performance and warranty for the price. Well-suited for the classroom or conference room, the TX542-3D is a XGA DLP projector with up to a 5,000-hour lamp life, a filter free design and Optoma's 3-year express replacement service. An above average performer on 2D video and static presentation material, the TX542-3D is also 3D capable and supports refresh rates up to 120Hz.


Brightness: While our review sample did not perform to Optoma's specifications, it produces enough light output to be capable of performing in a variety of use settings. The TX542-3D measured a peak brightness of 1,968 ANSI-lumens or just over 70% of the 2,800 ANSI-lumen specification. Peak light output was found using Bright lamp mode and the Bright picture preset and increasing the Contrast setting to 60. Brightness uniformity was a high 82% making any differences in brightness across the screen imperceptible.

1,968 ANSI-lumens can support a 4:3 aspect ratio unity gain screen of 135 inches in diagonal with a 30 foot-lambert brightness level, bright enough for use with non-direct ambient light in the room. A 100-inch diagonal screen would result in a brightness level of almost 60 foot-lamberts, which allows the TX542-3D to be used in environments with significant amounts of ambient light.

Across different picture modes, the measured reduction between Bright and Eco was only 7-9%. Power consumption between Bright and Eco was in-line with the measured difference in light output. Measured using a Kill-A-Watt meter, the TX542-3D consumed 225 watts in normal mode and 207 watts in Eco mode or 8% less power in Eco mode.

I'm new to the 3D game. How do you "bind" a pair of 3D glasses to this projector to view a 3D image? Say, for example, I wanted to play my PS3 in 3D with this projector. What type of 3D glasses would I need to purchase, and how do I get them to work with the projector (the users manual does not explain how to "Bind" to any sort of active 3D glasses)?

We bought our first one brand new in October 2010.

1. lamp failed prematurely and there was some uncertainty about whether it was a lamp issue or a projector issue so we exchanged it for a refurbished unit.

2. Refurbished unit exhibited DLP/DMD "white/black dots" failure within a few short months so we exchanged it for another refurbished unit.

3. 2nd Refurbished unit exhibited DLP/DMD "white/black dots" failure within one month so we exchanged it for another refurbished unit.

So far, Optoma is honoring the warranty, but at this rate, we wonder how many more exchanges will be necessary before we finally get a functioning projector.

So far so good. I use my projector for about 4 to 6 hours a day in my classroom (high school mathematics). I use the projector the months of May. August, September, and so far in October 2015. The projector projects perfectly for me. The clarity has been excellent.

This is a continuation of October 17, 2015 comments. I still haven't had any problems with the projector. I am planning to hang it from the ceiling of my classroom in the next seven days. I just came to this site to see if it will project on a 94 (wide screen)inch diagonal Smartboard. I am currently using a 77 inch diagonal Smartboard with the project about 10 feet away on a desk. Are they any comments about the projector ability for widescreen projection?
