How big screen I need?

Cheap projector tips.

Everytime I go to movie theaters, I always selected my favorit row, about third-fourths the way back. Another couple came in and promptly climbed the steps to the uppermost seats that were farthest from the screen. Another group arrived and chose seats about a third of the way back. Two teen-aged boys took the front row. Another dozen people filed in and took places randomly throughout the theater.
The point is that everyone has his or her own preferences for seating in a movie theater. Some like a bigger picture with a wider angle of view; others prefer a less overwhelming presentation more in the center of their field of vision. The beauty of designing your own home theater with a front projection system is that you can set it up exactly as big as you want it. There are no formulaic "ideals." In essence, when you select the size of your screen for your given viewing distance, you are "choosing the row" you want to sit in.
Now. Having said that, there are two things to be aware of. Both have to do with over-doing it. Since we have total freedom to go as big as we want, many folks err on the side of going too big and sitting too close, on the theory that if big is good, bigger must be better. And while it is true that size counts when it comes to home theater, it can be overdone to the point where it is not enjoyable.
So as you plan your theater's layout, be aware that watching a very big screen up close is physically demanding. Have you ever tried to watch a tennis match from side court in the first row? Your head is moving constantly and your eyes go buggy. It is not a pleasant experience. If you go too big with your screen, you will have the same effect. The huge image might have awesome impact for the first 30 minutes of viewing, but it will be a chore to watch it for long periods of time.
Before you choose your projector and screen combo, one practical exercise is to mark out on your wall the size screen you think you might want. You can use black electrician's tape to define the corners of your future screen. Place your seating at the distance you prefer, sit down, and look at the marked out screen area for a while. Imagine action happening in the screen space and get a sense of how much work your eyes need to do to view the image. Work with the image size and viewing distance until you feel it is a comfortable solution for you and anyone else in your household who might be a regular viewer.
Meanwhile, as you experiment with your ideal screen size, there is a second thing to be aware of. The more you enlarge a projector's image and the closer you sit to the screen, the more visible various artifacts become. By the way, the same is true of television. If you view a 2-foot wide television screen from a distance of 2 feet, you will see a blinding mass of scanlines and artifacts. But that same picture viewed from ten feet away looks great. There's nothing different about a projector except the scale.
As a rule of thumb with 720p resolution projectors, a viewing distance of less than 1.5 times the screen width will get you into the trouble zone where pixelation and artifacts become more visibly intrusive. While it is true you have a very BIG image in front of you, these distractions can compromise viewing satisfaction. On the other hand, with the new 1080p resolution projectors, you can sit a bit closer, say at 1.2x the screen width, without worrying about pixelation and artifacts. That still might be too close for comfort from an aesthetic point of view, but some people like to have that very large image in front of them. The 1080p projectors make it easier to do that and still get a clean image.
Keep in mind also that the screen's height will influence ideal viewing distance. Let's assume you have a 16:9 screen that is eight feet wide, and you find that 12 feet, or 1.5x the screen width, is a comfortable viewing distance. If you were to replace that 16:9 screen with an eight foot wide 4:3 screen, you might suddenly feel like your 12 foot viewing distance is too close--for any given screen width, the 4:3 format is always a larger surface area than 16:9, and is thus more visually demanding. You might want to move back a few feet to take it all in.
These are just rules of thumb. Clearly the projector you choose will have some impact upon ideal viewing ranges. 1080p resolution projectors will allow for larger screens and closer viewing distances without compromising image integrity. On the other hand, entry level 480p projectors require you to sit further from the screen if you want to avoid visible pixelation.

DLP Projector

Cheap projector tips


Best choice for your cheap projector is DLP technology.

DLP® technology is the only display solution that enables projection systems to create a purely digital connection between a digital video or graphic source and the screen in front of you. While all other technologies are analog and compromise some image quality in translation, DLP® projection unleashes the full potential of the content you want to see-whether it's in a movie theatre, the office, or your own living room.



DLP® projection outshines analog technologies because it brings more light from lamp to screen. The Digital Micromirror Device at the heart of DLP® technology works more efficiently than the cathode ray tubes (CRT) and D-ILA systems found in many televisions. While these analog technologies tend to lose a certain amount of light in transit, DLP® projection's greater efficiency creates exceptional brightness that increases with resolution, and does not degrade over time.

In home entertainment systems, DLP® technology produces a stunning show that plasma televisions and CRT televisions cannot match. And in the office, the superior brightness of DLP® projection gives presentations maximum impact-even in rooms where ambient light is difficult or impossible to control.

Images and video displayed with DLP® projection's unique reflective technology appear seamless at any resolution. That's because the hundreds of thousands of mirrors making up the Digital Mirror Device in a DLP® projection system are spaced less than one micron apart, resulting in a 90% fill factor. Because the gaps between pixels are minimized, DLP® projection comes closer than any other technology to producing the exact mirror image of an incoming video or graphic signal.

The difference is easy to see. DLP Cinema® projects a crystal clear movie onto every inch of the screen, every time-eliminating the scratches, flutter and focus problems that come with film.

And the close spacing of the DMD mirrors means that presentations, videos and other projected images never have the pixilated or "screen door" effect apparent in LCD-projected images at higher resolutions.

DLP® projection systems are more reliable than the analog alternatives because, being digital, they are able to recreate their incoming video or graphic source material every time they project it. Unlike cathode ray tubes, which move out of alignment over time, or DILA systems, which are susceptible to distortion, or film, which inevitably ages, DLP® projection quality does not deteriorate with ongoing use. In other words, projection systems using DLP® technology enable you to see the creator's original vision at full impact again and again, no matter how many times a video or graphic has been projected.

LCD projector

Cheap projector tips

LCD is mean Liquid Crystal Display. LCD projectors send light from a halogen lamp through three LCD panels, the red, green, and blue components of the video signal to display an image. As light passes through the panels, individual pixels can be opened to allow light to pass or closed to block the light. The combination of open and closed pixels can produce a wide range of colors and shades in the projected image.

Halogen lamps are used because they output an ideal color temperature and a broad spectrum of color. These lamps also have the ability to produce an extremely large amount of light within a small area: current projectors average about 2,000-4,000 ANSI lumens.

LCD projectors tend to be smaller and more portable than other types of projection systems because its small halogen lamps and the ability to project an image on any flat surface. But the best image quality is found using a blank white or grey surface, so dedicated projection screens are often used.

Perceived color in a projected image is a factor of both projection surface and projector quality. Since white is more of a neutral color, white surfaces are best suited for natural color tones; as such, white projection surfaces are more common in most business and school presentation environments.

However, darkest black in a projected image is dependent on how dark the screen is. Because of this, some presenters and presentation space planners prefer gray screens, which create higher perceived contrast. The trade-off is that darker backgrounds can throw off color tones. Color problems can sometimes be adjusted through the projector settings, but may not be as accurate as they would on a white background.

Early LCD systems were used with existing overhead projectors. The LCD system did not have a light source of its own: it was built on a large "plate" that sat on top of the projector in place of the transparencies. This provided a stop-gap solution in the era when the computer was not yet the universal display medium, creating a market for LCD projectors before their current main use became popular.

This technology is employed in some sizes of rear projection television consoles, as there are cost advantages when employed in mid size sets (40 to 50 inch diagonal). This is not expected to have much longevity in the "home theater" marketplace due to expected improvements cost/performance of competing technologies, particularly in direct-view LCD panels at the lower range of sizes and DLP projection in the larger sizes.[verification needed] Another advantage of using this LCD projection system in large television sets is to allow better image quality as opposed to a single 60 inch television, although currently an equal of an LCD projector is the LG 100 inch LCD TV, still in prototype stages this TV is a huge advancement towards projector sized televisions. A common rule of thumb is that an LCD's image quality will decrease with a size increase. A workaround is to use a small lcd panel (or panels) and project them through a lens onto a rear projection screen to give a larger screensize (with a decreased contrast ratio) but without the quality loss.

In 2004 and 2005, LCD front projection has been enjoying a come-back because of the addition of the dynamic iris which has improved perceived contrast up to the levels of DLP.

The basic design of an LCD projector is frequently used by hobbyists who build their own DIY projection systems. The basic technique is to combine a high CRI HID lamp and ballast with a condenser and collector fresnel, an LCD removed from a common computer display and a triplet.

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.

So how I can calculate fL of my room?

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.
