Acer P1257 projetor XGA DLP 4500 ANSI lúmenes 20000:1 MR.JYY11.001

The Acer P1257 (MR.JYY11.001) is a high-brightness DLP projector designed for business presentations, educational environments, and conference rooms. Delivering 4500 ANSI lumens with a native XGA (1024 x 768) resolution and a 20,000:1 contrast ratio, it produces crisp, vivid images even in rooms with ambient lighting — making it a practical choice for daytime use without requiring heavy blackout curtains.

Advantages

The single-chip DLP engine with UHP lamp technology provides reliable, accurate colour reproduction and an impressive lamp lifespan: up to 6,000 hours in standard mode, 10,000 hours in Eco mode, and 15,000 hours in ExtremeEco mode, significantly reducing total cost of ownership over the product lifetime. Vertical keystone correction of +/-40 degrees allows flexible placement angles without distorting the projected image, while the 1.94–2.16:1 throw ratio suits a wide range of room sizes. A built-in 3W speaker covers audio needs in casual presentation settings without requiring external equipment.

Suitable for

• Business professionals delivering slides and video content in meeting rooms and conference halls
• Educational institutions needing a reliable, bright projector for classroom use
• Training centres and auditoriums requiring large-screen display with low lamp maintenance costs

The IR remote control allows adjusting settings and switching inputs from the audience position.
