Home theater enthusiasts tend to prefer aspect ratios because they are closer to original 35mm film format. Set your DVD player to output to a television and the projector to mode to achieve the desired results. Now, nearly all home theater manufacturers have 3D models. Prices are dropping and content is becoming more readily available.
Many cable providers even offer 3D channels and programs. This specification is actually referring to the 'half-life' of the lamp, the point where the lamp is half as bright as it was new. The lamp will still work at its half-life, but it will continue to gradually lose brightness. Longer lamp life means less expense in maintaining your projector.
If you are planning to use your projector to replace your current television, lamp replacement cost should be factored into your purchase.
If your projector will be used primarily for watching movies and special events, lamp life won't be as important. Quick Tip: If you purchase a spare lamp with your projector, run it in your projector for a few hours first, then store it somewhere cool and dark. Lamp warranties begin from the day of purchase, not from the day of use. If a lamp is faulty, it will usually fail within the first 4 to 10 hours of operation. One choice you should make early on in your purchasing decision process is whether you want to ceiling mount your projector or simply put it on a tabletop when in use.
Each option has its advantages. Ceiling mounting your projector will get it out of the way, creating a more polished look for your viewing area while also keeping your projector secure. Mounting the projector in a fixed area will also save you the time of setting up your projector for each use. If you plan to ceiling mount your projector, you will need to know the fixed distance between the projector and your screen. This is because different projectors have different throw ratios.
Throw ratio is the relationship between the projector's distance from the screen and the width of the image. For example, if your projector will be ceiling mounted 10 feet away from your screen, your image will be larger than if your projector is only five feet away. Most video projectors weigh less than 20 pounds and are easy to transport from location to location. That means you can take your 'big screen TV' with you to the homes of friends and family, or host an outdoor movie projected on the garage door without any heavy lifting.
However, you will have to set up your projector for each use, and your primary viewing area will not have the polished look of an installation. If you decide that tabletop projection is right for you, consider a projector with less fan noise. Aim for around 30dB or less for 'whisper quiet' fans.
You may also want to consider the overall product's exterior design since the projector will be visible. Quick Tip: Projector People recommends that you purchase your projector before purchasing a screen.
Install your projector first, start it up, and then decide which screen best fits your needs. Manufacturers offer various levels of warranty depending on the projector model.
Low cost projectors typically come with shorter warranties e. Warranties also vary in the type of service provided. A return to base warranty means the projector needs to be sent back to a service centre while an on-site warranty often means a technician comes on site to repair or swap the projector. Always check the full terms of the warranty.
If you choose a projector with a lamp light source, as well as the cost of replacement lamps, check the expected lamp life. Some projectors, in particular brighter ones, have a lamp life of around to hours however many newer models have lamp lives up to The longer the lamp life.
The less maintenance and replacement will be required. If you need other inputs or outputs to connect specific equipment, it is important to check that the projector has what you need. Some models but not all include in-built or optional wireless connection which is useful for portable applications or when multiple laptops need to connect to the projector in a meeting. If the projector is going to be used in various locations and needs to carried, weight and size will be factors.
For mobile applications such as sales or on-site training, a light and compact projector would be recommended. There are projectors in the region of 1.
While both DLP and LCD projectors are suitable for most applications, there are small differences that may be important to you. Typically a projector should be installed centred with the screen horizontally and near level with the top for ceiling mounted solution or bottom for table mounted of the image for best results. If the projector needs to be mounted higher or lower, it will need to be tilted up or down; if it needs to be off-centre horizontally, it will need to be turned slightly left or right.
Tilting or turning the projector will cause the image to become a trapezoid. To correct this you can use a projector with keystone correction or lens shift. It preserves the quality of the image. Keystone correction is a digital process that contracts the image on one side horizontal keystone or at the top or bottom vertical keystone to make it rectangular again. This process may be necessary at times but should be avoided if possible as it reduces the quality of the image.
Projectors can come with additional features which may be required or useful. Some projectors can project files and photos from a USB memory drive. This is often called PC-less presentation and is not available on all models. There are projectors with interactive features allowing you to interact with your software without the need for an interactive whiteboard. For more specialised applications, there are features such as edge blending which allow 2 or more projectors to be used together to make one large, seamless image; geometric correction which allows projection on a curved surface without distorting the image; portrait projection allowing the image to be projected in portrait orientation rather than landscape.

Less than lumens Most projectors in this category tend to be portable, LED projectors for home entertainment or on-the-go applications as they must be used in dark rooms to ensure an optimal picture quality contrast levels. Over lumens Projectors over lumens are typically used in large venues such as auditoriums, Churches, halls etc.
Entry level projector resolution which is quite popular thanks to the lower purchase cost. A very popular resolution for business and education projectors in the recent past but which is gradually being phased out for widescreen resolutions. Currently one of the most popular widescreen resolutions thanks to the affordable cost; used mainly for corporate or education application.

An increasingly popular widescreen resolution for corporate projectors, offering high clarity. An increasingly popular resolution for both high end home cinema applications and corporate use.

Lens ratios and projector types Most standard projectors have lens ratios between 1. Short-throw projectors When you have limited space, a short-throw projector may be required. Ultra-short throw projectors Ultra-short throw projectors are designed to be wall mounted above the projection surface typically a traditional whiteboard, interactive whiteboard or fixed frame screen or on a cabinet below a screen e.
