Slide shows and overhead projectors with images that are crooked, upside down, mirror imaged, or simply lost, are well and truly a thing of the past. Data projectors suited to PowerPoint presentations and video projection are now quite affordable.
Prices vary with the features included, but not surprisingly the cost of projectors has dropped significantly in recent years. In 2003 the devices ranged in price from about AU$8000 to AU$15,000. The machines featured in this review range from AU$3600 up to AU$10,000.
The rise in the home theatre market has seen prices reduced through high-volume sales and every company with an electronics background seems to be making data projectors to cash in on this expanding market.
Little seems to have happened in terms of lamp technology since similar products were
reviewed in 2003. Prices, lifespan, and brightness seem to have gone nowhere fast. Lamp price is something we would like to see drop given that it costs six to eight hundred dollars for a single lamp, which means about thirty to forty cents per hour (plus electricity). Efficiency is a tiny bit better since 2003, and most machines have an energy-saving mode, which uses a lower light level and can reduce machine noise significantly.
All projectors have vertical keystone correction, but some also have horizontal correction. Image brightness and size will also vary, so consider the size of the room that you will be using and the amount of ambient light -- some rooms are difficult to get really dark, but with a powerful lamp this may not be a serious issue.
Lamp doesn't last long enough for the price.
There isn't enough IR ports.All ok if you don't mount it but once mounted IR ports just not good enough
