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.
