Here’s an example of a good projector:
2600-lumen High-Brightness Mobile Projector
MODEL: NP-V260
This product has been replaced by NP-VE281
The NEC V260 is designed to provide higher brightness for meeting and conference rooms that have heavy ambient light but require a small projector. These lightweight mobile models are 3D Ready and include a 7W speaker, closed captioning and NEC’s Virtual Remote control software. Their VIDI technology, a Philips innovation designed to work in conjunction with the color wheel, uses a brilliant pulse to increase the brightness of the image and a dark pulse to increase the contrast ratio.
Automatic Power ON via RGB (15-pin) input
BrilliantColor™, including a 6-segment color wheel, provides accurate color reproduction
Quick startup/cooling/shutdown minimizes projector setup and teardown between meetings
ECO Mode™ technology helps extend lamp life and lowers power consumption
Carbon savings meter calculates the positive effects of operating the projector in ECO Mode
Compact size and lightweight design simplify transport.
