Choosing the right projector is only a simple issue at first glance – the multitude of offers available on the market means that we need to carefully define our priorities so that we can be satisfied with our purchase.
Video projectors can be used not only at home, but also in office conditions or in a classroom. Before you ask yourself which projector to choose, it’s a good idea to analyze what it really is and what you can expect from a Video projector.
Are there any characteristics that define Video projectors in particular? As we are going to learn, it’s not just about the projector meeting certain criteria, but also about meeting them adequately to the content type and conditions it is going to work in. Let’s take a look at the key characteristics of projectors from the right point of view.
Projectors used to display Video offer a very vast array of resolutions these days, from SVGA all the way to 4K. The higher the resolution, the better. It will be useful when displaying Pictures, educational Videos, and especially if we go for large display dimensions.
The most popular Video resolutions are:
The most convenient option is a projector with resolution of 1920 x 1200 pixels (WUXGA), which allows to adapt not only to high-resolution content, but also that with aspect ratio of 16:10.
An alternative when choosing a projector for movies is a projector with FullHD resolution.
Projectors with XGA resolution still make sense when it’s about very high brightness and not a very high purchasing budget.
The lamp is the basic element inside a projector. Its lifespan and efficiency will impact the quality of the Video displayed. By default a lamp should be able to last for about 2,000 hours in the normal mode. When using the energy-saving mode, this time gets extended to 3,000 hours. If that time is shorter, we should look for projectors with lamps of better quality.
The parameter is very important when the projector is intended to be used intensively and frequently. After the time period specified by the manufacturer, a new lamp has to be bought, which makes it a good idea to check the cost of a new part and if it’s easily available.
When it comes to devices with lamp lifespan of about 4,000 hours, if the projector is to be used 7-8 hours a day, the lamp will have to be replaced after just 1.5 year. It’s a good idea to pay attention to this parameter if the projector is to be used instead of a TV set.
When it comes to Colors, it’s easy – although LCD projectors may provide more saturated Colors, the new generation DLP projectors not only can handle faithful representation of black but also the color pattern of a Video.
What matters more than the display technology is technologies that support compatibility with different color spaces. For example, compatibility with REC.709 translates to overall very good working with Colors regardless of the input material.
The contrast is important when choosing a projector for the home theater or planning to use the projector in darkness. In such case, the contrast ratio is recommended to be as high as possible. If the projector room has at least a little available light then this parameter doesn’t make much difference. The HDR technology in Video projectors doesn’t offer real possibilities as of now.
There are also projectors that support the 3D technology. All you have to do is plug the projector into the 3D source and have matching 3D glasses.
