Epson PowerLite 905 Conference/Classroom Projector Review
Auto Source Search: The 905 has a convenient Source feature that relieves you of remembering which of your connected sources is active. On power up, the 905 searches all inputs and selects the first active connection it finds. When the Source key is pushed on the remote or the projector keypad, it begins searching and selects the next active connection it detects.
Quick start/stop: On applying power, the 905 is up to full brightness in less than 30 seconds, so you won't be delayed by a long warm-up period. When it is time to shut down, there is no need to wait for a cool down interval . . . you can pack up the projector about five seconds after you hit the power switch.
Computer-free Presentations: Do your students want to show a bunch of photos or a PowerPoint presentation they concocted as part of a homework assignment? That is no problem for the 905 . . . photos and converted Powerpoint files (Epson provides the conversion software) can be stored on a USB thumb drive that plugs into the 905 without the need for a computer. Files can be selected and controlled with the 905's remote control.
Wireless Presenting: If you want to connect several PCs, then the extra-cost LAN module and USB key will be worthwhile as they eliminate cable swapping, function key activation, and other time-consuming and distracting activities. With the 905's wireless connection LAN hardware installed, you simply install the USB key sequentially in each PC (not Mac-compatible), and its output is wirelessly shown on the screen.
Audio Quality: Even though it develops a slight rumble at maximum volume, the 905's 16-watt speaker is plenty loud for most classrooms. This eliminates the need for additional amplification equipment and reduces cabling requirements.
Lamp Life: Lamp life for the 905 is 5,000 hours in normal mode and Eco mode extends it to 6,000 hours, so you will not be replacing lamps as often as you must for most 3,000-lumen projectors. This is especially convenient if you have the 905 ceiling-mounted, and access is limited. A replacement lamp can be purchased from Epson for $299.
Warranty Provisions: Epson offers a 2-year warranty on the projector and a 90-day warranty on the lamp. They also have a very liberal replacement policy that provides shipment of a replacement unit to you before you ship yours back if trouble occurs.
No 3-D Compatibility: While 3-D content is still a bit hit or miss, there is increasing interest in this medium for the classroom. Unfortunately, the 905 is not capable of displaying 3-D images on its own, so you will have to forego this type of content.
Remote Control: Lettering on the remote control is small and contrast is minimal. There are also some double function keys depending on the current operation. In a darkened room, it can be a test discerning what key does what.
Maintenance: Like most LCD projectors, the 905 has an air filter that needs occasional cleaning with a small vacuum cleaner. The good news is that the filter can be replaced quickly if it becomes worn. Lamp replacement is reasonably easily as lamp access is through the top of the projector.
