dB — decibel — A unit used to express relative difference in power or intensity, usually between two acoustic or electric signals, equal to ten times the common logarithm of the ratio of the two levels.

Diagonal Screen — A method of measuring the size of a screen or a projected image. It measures from one corner to the opposite corner. A 9FT high, 12FT wide, screen has a diagonal of 15FT. This document assumes that the diagonal dimensions are for the traditional 4:3 ratio of a computer image as per the example above.

DLP® — Digital Light Processing™ — Reflective display technology developed by Texas Instruments, using small manipulated mirrors. Light passes through a color filter is sent to the DLP mirrors which arrange the RGB colors into a picture projected onto screen, also known as DMD.

DMD — Digital Micro-Mirror Device — Each DMD consists of thousands of tilting, microscopic aluminum alloy mirrors mounted on a hidden yoke.

Focal Length — The distance from the surface of a lens to its focal point.

Frequency — It is the rate of repetition in cycles per seconds of electrical signals. Measured in Hz (Hertz).

Hz (Hertz) — Unit of frequency.

Keystone Correction — Device that will correct an image of the distortion (usually a wide-top narrow-bottom effect) of a projected image caused by improper projector to screen angle.

Maximum Distance — The distance from a screen the projector can be to cast an image that is usable (bright enough) in a fully darkened room.

Maximum Image Size — The largest image a projector can throw in a darkened room. This is usually limited by focal range of the optics.

Minimum Distance — The closest position that a projector can focus an image onto a screen.

NTSC — National Television Standards Committee. North American standard for video and broadcasting, with a video format of 525 lines at 30 frames per second.

PAL — Phase Alternating Line. A European broadcast standard for video and broadcasting, with a video format of 625 lines at 25 frames per second.

Reverse Image — Feature that allows you to flip the image horizontally. When used in a normal forward projection environment text, graphics, etc. are backwards. Reverse image is used for rear projection.

RGB — Red, Green, Blue — typically used to describe a monitor that requires separate signals for each of the three colors.

S-Video — A video transmission standard that uses a 4-pin mini-DIN connector

One of the standout characteristics of the Dell 1410X is its impressive brightness level, capable of delivering up to 2500 ANSI lumens. This high brightness ensures that presentations can be viewed clearly in various lighting conditions, making it suitable for both darkened and well-lit rooms. Coupled with a contrast ratio of 2000:1, images and text appear sharp and vibrant, providing a professional edge to any presentation.

The projector supports a native XGA resolution of 1024 x 768 pixels, which is optimal for displaying detailed graphics, spreadsheets, and videos. Moreover, it is compatible with a range of resolutions, allowing it to accommodate different types of media without compromising quality. The Dell 1410X utilizes a DLP (Digital Light Processing) technology, which enhances color accuracy and provides smoother transitions, making it ideal for dynamic video content.

Portability is another significant advantage of the Dell 1410X. Weighing around 5.7 pounds, it is easy to transport between locations, fitting well within a standard laptop bag. This makes it a popular choice for traveling professionals, educators, and presenters who require mobility without sacrificing performance.

Connectivity options are plentiful, including an array of inputs like HDMI, VGA, and USB, allowing users to connect various devices such as laptops, gaming consoles, and digital cameras seamlessly. Its quick start-up and shutdown capabilities further enhance convenience by reducing downtime in fast-paced environments.

In terms of durability, the Dell 1410X is built with a sealed optical engine designed to prevent dust accumulation, which ensures longevity and consistent performance. This feature, combined with a long lamp life of approximately 4000 hours in standard mode, minimizes maintenance efforts and costs over its lifespan.

Overall, the Dell 1410X projector exemplifies a blend of portability, performance, and ease of use, making it a worthy investment for anyone looking to enhance their presentation experience. Its robust set of features continues to meet the needs of users seeking reliability and quality in their visual presentations.
