Home LCD Video Projector Specs

Home LCD video projectors have replaced overhead, slide and conventional film projectors for conference room presentations, classroom training and home cinema.

LCD technology has been around for a few decades and is the preferred digital projection method in 2012. Learn more about what to look for in an affordable home projection system.

Screen Size

When setting up a home video projector system it is important to choose the right screen size for your room and seating arrangement. The wrong screen size can distort the image and cause eyestrain. The correct screen size will provide a crystal-clear display with sharp contrast and minimal distortion.

The first step in choosing the ideal screen size is to determine what aspect ratio your content will be displayed in. Most modern movies are shot in widescreen, which is a ratio of 16 units of width for every 9 units of height. Older movies and traditional TV shows use the squarish 4:3 format.

Next, measure the distance from the lens of your projector to the screen. This is known as the throw distance. Then consider the type of content you plan to watch and your viewing preferences. Some people prefer to sit closer to a screen, while others like to sit farther back.


The resolution of a projector determines the number of pixels that can be displayed on the screen. Pixels are the individual dots that make up a picture, and more pixels usually means a sharper image. However, resolution alone is not the only factor to consider when choosing a home video projector. There are other considerations like the size of the projection screen and the viewing distance that will also impact image quality.

Having the right resolution is important because it will ensure that your images remain crisp and clear regardless of how large or small they are. You will need to match the native resolution of your projector with the resolution of the source content that you’re displaying. If you have a projector with a high native resolution and your content is in a lower resolution, the projector will be forced to scale the picture down which can cause it to look blurry.

Contrast Ratio

Contrast ratio measures the brightness of white versus black on the screen. A high contrast ratio allows you to see details in the image.

A projector with a higher contrast ratio will have a larger range of brightness levels and thus be able to display more vivid colors. The contrast ratio of a projector can also be affected by ambient lighting.

The best method to determine a projector’s contrast ratio is through Home LCD video projector the ANSI (American National Standards Institute) technique. This method uses a sequence of alternating patterns of white and black rectangles to measure the contrast ratio.

Unfortunately, the ANSI contrast ratio numbers quoted by manufacturers are often misleading. They use a sequential contrast method, and the resulting high “ANSI” contrast ratings do not represent the actual contrast span you will see during movie content. You may be surprised to find that two projectors with a low Full On/Off contrast rating look very similar, while one with a high ANSI rating looks terrible.


Brightness is a critical projector spec, as it determines how crisp and clear a projected image can be. The brightness of a projector is typically measured in lumens. However, there are several factors that impact a projector’s brightness.

One important factor is ambient light, which can diminish contrast and make the projected image look dimmer. Ambient light can also interfere with the focusing of the lens, which can affect the image’s clarity.

In addition to ambient light, the type of content and screen size can also impact brightness. For example, high-resolution content and larger screens require higher brightness levels.


Color performance is often a key feature in home theater projectors, especially for high-end models that boast THX and ISF certification. In order to display accurate colors, projectors utilize 3LCD chips that contain microscopic tilting mirrors – one for each primary color (red, green and blue) – and which are overlapped and converged before being projected onto your screen.

The image above shows two particular barebones projectors in their brightest pre-programmed operating modes, typically called “Dynamically Powered” or “Presentation” on most units. The LCD’s tendency to undersaturate pastels at higher brightnesses can be seen here in the white reflection glare on the pencils and its bluish tint overall. By contrast, the DLP maintains more balanced wireless wifi projector highlights and a more neutral color balance on this scene of natural-looking foliage. The DLP is also much better at holding detail in dark scenes and has a higher apparent contrast than the LCD.


The sound quality of a projector is important for providing an immersive audio-visual experience during presentations and events. Many modern projectors have built-in speakers, and some also support external speaker systems to deliver high-quality sound.

Whether you’re hosting friends for movie night or enjoying a quiet evening in, a home projector is the perfect way to enjoy your favorite movies and TV shows in a large, cinematic format. However, it’s important to understand the different specs and features of a projector before you make your purchase.

The basic design of a video projector is an LCD (Liquid Crystal Display) screen with a light source and a lens. The light is projected onto a flat surface, creating an image that’s up to 150 times larger than the original source. The images can be seen in ambient light because of the low power consumption and high brightness levels of LCD projectors.
