If you're looking for a projector for a large hall, then the Epson EB-2250 is the right choice for you. This projector has a light output of 5,000 ANSI lumens. This ensures a clear projection, even in brightly-lit conference rooms or lecture halls. It doesn't matter if you project an image size of 50 or 300 inches, details, such as small letters or digits, will be clearly visible thanks to the WUXGA resolution. Use the VGA or HDMI port to connect a computer or laptop. You can subsequently send the images on the device to the projection screen or wall. Do you feel that the 16-watts speaker isn't powerful enough? In that case, you can easily connect an external speaker set with the 3,5mm port.
