Brightness and Resolution for Home Cinema

This new DLP projector delivers 2500 lumens of brightness and a native 1280 x 800 resolution. It supports HD video input up to 1080i for clear widescreen viewing. Built-in speakers provide audio without external equipment.

Fixed Installations and Portable Use

The unit suits home theatre enthusiasts, offices, classrooms and places of worship needing flexible placement. Ceiling, rear and table-top projection modes are all supported. Buyers requiring higher native pixel counts or wider connectivity options should consider other models.

1280 x 800 Native Resolution Decides Fit

The fixed DLP chipset means the projector cannot display finer detail than its 1280 x 800 grid. Content at 1080i is scaled to match this native array. Verify that this resolution meets the clarity needs of your intended screen size.

Questions about this item

How can I verify the 1280x800 native resolution is displaying correctly after setup?

Display a 1280x800 test pattern via HDMI or VGA and confirm pixel-perfect mapping with no scaling artifacts on the DLP panel.

Which cables and accessories are included versus what I must source separately for HDMI, VGA and LAN connections?

The unit ships with standard accessories for HDMI, VGA/SVGA D-Sub, USB, RCA, Mini Jack, RJ-45 LAN and DB-9pin; verify the exact cable bundle on arrival.

Should I choose the 2500 lumen rating or the 2999 lumen upper figure for a living-room home-cinema setup?

The projector delivers 2500 lumens; the 2999 figure is the top of the brightness class range, not a selectable mode.
