One of the key features of the VT770 is its native XGA resolution (1024 x 768 pixels), which ensures clear and detailed images. It utilizes a 3LCD technology, which contributes to bright, vibrant colors and high light output. With a brightness rating of 2800 ANSI lumens, it performs exceptionally well in diverse lighting conditions, making it suitable for medium to large-sized rooms without compromising image quality.

The VT770 offers a contrast ratio of up to 600:1, which enhances the distinction between the brightest whites and the deepest blacks.
