Acer P1273 User Reviews
User ReviewsWrite a Review
The projector works well. It does get very hot but so do most. Everything on the projector works as advertized and the optics seem sound. Limited to 1024x768 via VGA, USB and network connections (no down scaling by projector). I have not tried HDMI yet. Wireless works well (1273i) and it is possible to connect up to 4 input sources to it using eDisplay. Have not tried the higher end SW. Feature rich is an understatement. I am quite happy with my purchase.
Any Problems: Documentation is sparse. Took three levels of tech support to provide me the key to getting everything working. Via the web or USB by default the eDisplay password is the projector ID (AcerProjector but you can change it). The admin login via the web (different than in the documentation) is 123456 by default. This took 5 days dealing with the projector to get. Now it is working like a champ. I am not impressed by the remote controller operation but it works once you get used to it.
It turns out there are various subtypes: P1273, P1273n, P1273B, P1273i. This review is for the P1273 only. - The P1273 plain version does not have any filters, nor a regular USB port. - Easy to set up and use. - I like the automatic keystone correction feature. - The horizontal and vertical controls on the menu are only for centering the laptop projection in the screen (by millimeters). You cannot move the projection sideways on the wall like an offset feature would. - I would prefer one menu system. The unit has two separate menus and their submenus.
Any Problems: 1). Turns out the mini-usb port is only used to control a slideshow. I mean things like page up and page down while connected to a laptop. It cannot be used as a connection to the laptop for video or sound = still need some other cable like VGA + audio, or HDMI. 2). I wish the instructions had told us which cables / formats carried both video and sound. These do: HDMI alone. These don't: VGA, S-video, component video, composite video, ps-2 (old style computer mouse) connector. 3). The VGA output (for a second monitor) only works if you are also using VGA input. Won't function with any other input. 4). I was unable to find any use for the buttons on the remote that indicate play, rewind, fastforward. 5). You will have to buy an HDMI cable. And when you do, you will have a choice of one without an amplification chip in the connector or with an amplification chip. Get the one without. I bought a cable with an amplification chip and it is directional. Plug it into the laptop / projector with the wrong end and the connection is recognized but there is no image until you swap ends around.
