Resolution for cheap projector

Cheap projector tips

Resolution is the number of pixels that it has available to create an image. The higher the resolution of a cheap projector, the more pixels it has.

Projector resolution is designated with two numbers (800x600, 1024x768, 854x480, 1280x720, etc). The first number indicates how many pixels there are in each horizontal row, and the second number is how many pixels make up each vertical column. If you were to multiply the two numbers, you would end up with the total number of pixels on the display device.

The higher the resolution, the more the projector will cost. The advantages of higher resolutions are that:
- they can display more detail in the picture (
- they reduce or eliminate the visibility of the pixel structure.

Both of these are highly desirable in good home theater. The advantage of low-resolution projectors is that they cost so little, so you can get into large screen home theater with a small investment.

Resolution 854x480. This is the least expensive and lowest resolution on the market. It is designed for optimum display of standard definition material in NTSC countries, since both NTSC television signals and standard DVDs contain 480-lines per frame of video. An 854x480 projector can display 480-line video without any vertical scaling, so the picture will look its sharpest. If you live in an NTSC country, you watch primarily DVD and television, and want to get a good basic projector for the least cash outlay, the 854x480 models may be just right for you.

Resolution 1024x576. There are few projectors in this resolution these days, but you can still find them on the used projector market. They were designed for optimum display of PAL/SECAM video, which contains 576 lines per frame. They have little practical use in NTSC countries. But if you live in a PAL or SECAM country, these can be inexpensive alternatives that are ideally suited to viewing standard definition PAL/SECAM video.

Resolution 1280x720. This is currently the most popular home theater projector resolution on the market. Most 1280x720 projectors offer very well to excellent DVD video quality. In addition, they have the unique advantage of being able to display HDTV 720p in native format without scaling. They also do a beautiful job of displaying 1080-line video; even though the signal is compressed into its 720-line format, it still comes out looking like true high definition. Street prices on the most aggressively priced models have dropped below $1,000, so this excellent resolution format is easy to get into from a budget perspective.

Two recommended resolutions for widescreen, 16:9 format home theater, those being 1280x720 and 1920x1080. If you want your projector to double as both a video and data projector, the 1280x768 format should be considered as well.

The best choice is 1280x720 format. Today's 1280x720 projectors (often referred to in shorthand as "720p projectors") deliver beautiful high definition images from HDTV 720p, 1080i, as well as HD DVD and Blu-ray disc players, so there really is not much of a compromise in picture quality by going with 1280x720 instead of the higher resolution 1920x1080 format.

Contrast setting for cheap projector

Cheap projector tips

Contrast setting for cheap projector is very important.

For presentation projectors, lumen output is of primary importance, and contrast is a secondary concern. But home theater projectors are the exact opposite. Contrast is arguably the single most important measurable quality in a home theater projector. A high contrast projector produces a picture with a rich, dynamic look, good shadow definition, and deep color saturation. Contrast gives "depth" to video images. A projector with excellent contrast can make a two-dimensional image appear almost three-dimensional.

Definition of contrast is the difference between maximum white and deepest black in an image. The greater the difference, the higher the contrast.

There is two kind of contrast. On/Off contrast and ANSI contrast.

Some typical On/Off contrast figures for home theater projectors are as follows:
2000:1
There are many entry-level projectors rated at 2000:1 on/off contrast. 2000:1 is typically enough to give satisfying black levels and color saturation, enough to avoid the sense of flatness or muddiness in a picture.
5000:1
Projectors rated at 5000:1 are usually capable of better blacks than 2000:1 projectors, and shadow details are better defined. In today's market, 5000:1 represent the midrange of performance for good home theater projectors.
10000:1
As of this writing, if you want the best contrast that money can buy, you want a projector rated at 10000:1 contrast or higher. These projectors offer deep, inky black levels and excellent shadow detail that should be sufficient for even the most demanding content.

In ANSI contrast, the ratio has been determined by displaying a checkerboard pattern of white and black squares and measuring the relative brightness of each. ANSI contrast is accurate representation of what your projector is actually capable of during normal use.

You've noticed that commercial movie theaters are dark, including dark ceilings and walls. That is because any front projection system looks its best when there is no light in the room. Once you introduce ambient light into the room, that light will hit the screen and make blacks look more like dark gray. This reduces the contrast of the image, and makes it look flat or washed out. And this will happen no matter what the contrast capability of your projector is.

Though the ideal viewing room is dark, most people don't want to darken the walls and ceiling of a living room or multipurpose room just to get ideal theater conditions. Today's high contrast gray screens help to hold black levels solid when there is some ambient or reflected light bouncing from light colored surfaces in the room back onto the screen. But for the best possible image quality for any home theater, take whatever steps you can to eliminate ambient light and reduce the reflectivity of the room's walls and ceiling.

How much brightness do I need for my cheap projector?

Cheap projector tips

Brightness depends on three factors: (1) the light output of the projector, (2) the reflective properties of the screen, and (3) the ambient light of the room.

So, how much brightness do you need for your cheap projector?

When it comes to home theater projectors, brighter is definitely not better. What you want is a projector that produces enough light to fill your screen with good contrast, but not so bright that it creates eye fatigue when viewed for any length of time.

If you don't want to set up a dark home theater and would rather have some low ambient light, many users prefer to get the screen luminance up. A brighter picture will help compensate for the loss of contrast caused by the ambient light.

Whatever you do, don't make any assumptions about a projector's brightness based on its ANSI lumen rating. Some models have video optimization incorporated into their ratings and others do not. That means there are projectors out there, which are officially rated at 700 ANSI lumens that are actually brighter than models, rated at 1500 ANSI lumens. So the spec sheets, as far as lumen ratings are concerned, tend to be meaningless for home theater.

There are two common methods of measuring light in a home theater. One is the ANSI lumen rating of the projector. That measures the light energy capable of being generated by the projector itself. The second is foot-Lamberts (fL), which takes the screen into account and measures the total light that is being reflected back toward the audience. Of the two, foot-Lamberts are the better method to use for setting up your home theater. However, since that number depends on your screen size and screen gain, there is no fL specification published by the projector manufacturers.

Which Aspect Ratio for cheap projector?

Cheap projector tips

Aspect ratio 16:9 is good choice for you cheap projector.

Aspect ratio is about the rectangular shape of the video image. A standard TV has an aspect ratio of 4:3. That means the picture is four units wide for every three units of height. The movie standard is 16:9, which are 16 units of width for every 9 units of height. So movies 16:9 is horizontally wider than regular TV, which by comparison looks almost square.

Here's the problem: any given projector or TV comes in its own native format--typically either 4:3 or 16:9. On the other hand, movies and video come in many different aspect ratio formats. TV programs and videos intended for regular TV is done in 4:3. On the other hand, movies are in 16:9 format.

The most popular choice for a home theater system is to go with a 16:9 projector and a 16:9 screen. But some people still like the more classic format of a 4:3 projector with a 4:3 screen, since all classic films prior to 1953 were made in this format. And today there is a lot of interest in dedicated super-widescreen 2.35:1 systems as well. Each of these three configurations offers some unique benefits, as well as some disadvantages that should be considered before taking the plunge.

So if you want to view material such as classic films, or DVD-based television series like Friends or Northern Exposure, or an IMAX special like Everest in very large dramatic format, choose the 4:3 aspect ratio.

Unfortunately most high quality home theater projectors being marketed these days are in native 16:9. As such, it can be hard to find a 4:3 projector that delivers great video that rivals the quality of the 16:9 home theater models. And since most 4:3 projectors are in resolutions such as 800x600, 1024x768, and 1400x1050, it means that all video content will need to be scaled to fit the projector's native resolution.

And if you want to see from HDTV and widescreen DVD, 16:9 is the logical choice. All HDTV broadcast material is in 16:9, and it will be displayed in its full glory, without black bars, on a native 16:9 projector. And there is a lot of 16:9 programming available. There are many 16:9 projectors to choose from, and many of them are designed specifically for high quality home theater.

Type of video projector

Cheap projector tips

There are two main type of video projector: LCD and DLP projector.

LCD (Liquid Crystal Display) projector using LCD light gates. This is the simplest system, making it one of the most common and affordable for home theaters and business use. Its most common problem is a visible "screen door" or pixelation effect, although recent advances have minimized this.


DLP (Digital Light Processing) Projector using one, two, or three microfabricated light valves called a digital micromirror device (DMDs). The single- and double-DMD versions use rotating color wheels in time with the mirror refreshes to modulate color. The most common problem with the single- or two-DMD varieties is a visible "rainbow" which some people perceive when moving their eyes. Systems with 3 DMDs never have this problem. More recent projectors with higher speed (2x or 4x) and otherwise optimised color wheels have minimized this artifact.

What is video projector?

Cheap projector tips

A video projector takes a video signal from a player (vcd, dvd, etc.), then project the corresponding image on a screen or wall. Yes, just a white wall. You don't have to buy projection screen. :-)

Video projectors are widely used for conference room presentations, classroom training, and home theatre applications. Common display resolutions for a portable projector include SVGA (800×600 pixels), XGA (1024×768 pixels), and 720p (1280×720 pixels).

The cost of a device is not only determined by its resolution, but also by its light output, acoustic noise output, contrast, and other characteristics. While most modern projectors provide sufficient light for a small screen at night or under controlled lighting such as in a basement with no windows, a projector with a higher light output (measured in lumens, abbreviated “lm”) is required for a larger screen or a room with a higher amount of ambient light. A rating of 1000 to 1500 ANSI lumens or lower is suitable for smaller screens with controlled lighting or low ambient light. Between 1500 and 3000 lm is suitable for medium-sized screens with some ambient light or dimmed light. Over 3000 lm is appropriate for very large screens in a large room with no lighting control (for example, a conference room). Projected image size is important; because the total amount of light does not change, as size increases, brightness decreases. Image sizes are typically measured in linear terms, diagonally, obscuring the fact that larger images require much more light (proportional to the image area, not just the length of a side). Increasing the diagonal measure of the image by 25 % reduces the image brightness by 35 per cent; an increase of 41 per cent reduces brightness by half.
