Optoma TX536
Portable Multimedia Projector Review

Jeffrey Janas, September 25, 2009


Long Throw Ratio/Limited zoom range: The 1.1: 1 zoom range and a minimum throw ratio of greater than 2:1 limit the image size achievable for a given setup situation. In practical terms, the Optoma requires over 14 feet to produce a 100" diagonal image whereas a projector with a minimum ~1.5 throw can produce the same image size at a distance under 10 feet. This may or may not be a significant issue, as many mobile presentations do not require massive image size.

No Digital Input: The TX536 does not include a digital input, requiring users to rely on a standard 15 pin D-Sub monitor connection. While not a significant issue for the intended market, the lack of digital input does limit input flexibility and excludes this projector from consideration by those who demand a digital input.

Brightness Uniformity: Brightness measurements showed significant variance in edge-to-edge uniformity. Lumen measurements were approximately 40% higher on the right side of the screen versus the left when the projector was in a tabletop configuration. This variance in uniformity contributed to the gap in measured ANSI lumens versus the specification - the brightest point on the screen was much closer to the specification of 2,800 ANSI lumens. While the meter is sensitive to the differences in brightness across the screen, they are less noticeable to the naked eye when material other than a white screen is being displayed.

No Auto-Keystone: Many projectors in this class include an auto-keystone capability that will automatically square up the image based on the projection angle of the projector. Although the TX536 does not have this feature, keystone correction can be done via buttons on the remote control that make it quick and easy. Aside from the lack of an auto function, keystone correction performs well, producing text that is clear and readable even when applied at extreme levels.

No network capability: For fixed business or classroom environments, network capability provides advantages for integration into control systems. The TX536 does not have network capability, but does contain an RS-232 port for use as an alternative form of wired control.


Ideally suited for the mobile presenter, the TX536's small form factor makes it easy to transport from location to location and quick to setup and take down. With its low ownership cost, the TX536 is also great for classroom use that does not require an auto-keystone, a long zoom range, or network capability. The Optoma TX536 places a priority on image quality and value over bells and whistles. And in this it excels-the TX536 delivers sharp and bright images with great color for a very low cost of ownership.

Could you please inform me if this runs on 240 or 220 current as well as 110? We are traveling to Ethiopia to work and would like a projector that can run on both currents. Thanks

Is this compatable with MAC?
Jeffrey Janas Posted Dec 22, 2009 8:35 AM PST
@ Ed, Page 47 of the TX536 manual lists supported mac resolutions and refresh rates - so, the answer to your question is yes.

@ Mark, The spec sheet for the TX536 lists power compatibility as 'AC Input 100-240V, 50-650Hz, Auto-Switching' - looks like a yes as well

Regards, Jeff

Yes, it will run on 220/240 -- it's auto-switching, according to the specs.
