￿Setting Up the Screen and the Projector

Selecting a Location

The further your projector is from the screen or wall, the larger the image. The minimum size the image can be is approximately 30 inches (0.8 m) measured diagonally when the projector is roughly 51.2 inches (1.3 m) from the wall or screen. The largest the image can be is 500 inches (12.7 m) when the projector is about 970 inches (24.6 m) from the wall or screen. Use the drawing below as a guide.

LT245, LT265 specifications

The NEC LT265 and LT245 are two high-performance projectors that cater to business professionals, educators, and multimedia enthusiasts alike. Both models are part of NEC's range of advanced projection solutions, known for delivering superior quality and reliability.

The NEC LT265 is recognized for its impressive brightness of up to 3500 lumens, making it suitable for various lighting conditions, from dimly lit conference rooms to brightly illuminated classrooms. This model uses DLP technology, which enhances image quality through its ability to produce sharper and more vibrant colors. The LT265 features a native XGA resolution of 1024 x 768 pixels, ensuring that fine details in text and images are rendered with clarity.

One of the standout features of the LT265 is its extensive connectivity options. It includes analog and digital inputs, such as VGA, HDMI, and USB, making it compatible with a wide array of devices, including laptops, tablets, and desktop computers. Additionally, the projector offers a built-in 10-watt speaker, which provides sufficient audio output for presentations and video playback without the need for external speakers.

On the other hand, the NEC LT245 is designed for even broader versatility. It boasts a slightly lower brightness at 3000 lumens but maintains a similar XGA resolution. The LT245 excels in its lightweight and portable design, weighing just around 5.5 pounds, making it an excellent choice for professionals on the go. The projector's lamp life is rated at an impressive 4000 hours in standard mode and up to 6000 hours in eco mode, allowing for extended use and reduced maintenance costs.

Both projectors incorporate technologies like keystone correction and digital zoom, facilitating easy setup and adjustment of the projected image. Keystone correction allows users to eliminate distortion when projecting at an angle, ensuring a properly shaped image every time. The LT265 and LT245 also come equipped with a quick-start feature, enabling fast power-up times, which is crucial for time-sensitive presentations.

In conclusion, the NEC LT265 and LT245 stand out for their high-quality projection capabilities, reliability, and user-friendly features.
