Choosing a video projector
(Re)discover previous article: Tips And Tricks: Your AV Room Set-Up Projects
New technologies and lower prices make video projectors grow in popularity. They become more and more available and affordable for the average consumer. We’re thrilled to provide you with the key elements that will have real and powerful impact on your future purchases. This article gathers all the essential information you need to know before you undertake an Audio/Video project. Please don’t hesitate to contact us if you require any further information.
What use for a video projector?
Most internet guides recommend short-throw projectors for business and office purposes. They are rather adapted to small rooms with little space and no possibility to set the video projector at 2-3m (7-10ft) from the screen. Popular in schools and trade shows, they’re very efficient in the areas of high brightness. However, some models may cause some display glitches, especially at the edges.
Home Cinema users covet to recreate the real movie theater experience. In order to get the desired effect, they opt for high-quality display projectors, most efficient in dim rooms. Certainly, they aren’t tiny but can be set up wherever and however you like.
Video projector technologies:
Several technologies are available, but only two of them have taken over the marketplace.
LCD technology uses three panels based on three primary colors - red, green, and blue. Video projectors using this technology are rather light in terms of weight and of high color accuracy. However, some users are not satisfied with the quality of the screened image and the insufficient contrast ratio.
DLP uses tiny mirrors that reflect light toward the screen. This technology provides high light output (brightness). The quality of projected image and contrast are excellent. Some users were susceptible to notice trails of multicolor light called “rainbows”. Luckily, the problem has been solved and the latest projectors do not cause any color display-related issues.
2 most popular types:
Traditional projector lamps (bulb lamps) are very light but generate much heat. On average, they last approximately 2000 hours. At the end of their life cycle projected colors tend to lose intensity.
LED lamps have more qualities than traditional lamps. They last 15 times longer, generate less heat and the projection quality does not decrease over time. However, they do have limits. LED lamps provide less light output and are consequently less efficient in bright setting.
Brightness is measured in lumens. Light output should not be too high in a Home Theater in order to preserve a decent level of the contrast ratio. If a screening room is dim enough, 1 000 to 1 800 lumens projector is perfect. If the screening takes place in a bright room (like a business meeting room during the day), a 2 000 to 3 000 lumens projector would be required. In these conditions, a short-throw video projector Optoma W307USTi will do the job.
Resolution is crucial when it comes to high quality video projector display. The absolute minimum is 720p (1280x720) but it is better to invest in a higher resolution - 1080p (1920x1080). High Definition comprises these two resolutions.
Volume level is measured in Decibels (dB). Users keep neglecting this feature since it’s “invisible”. Yet, a noisy projector can be bothering while giving a presentation, and really disturbing during a movie screening.
The noise comes from the cooling fan. What you need to remember is that a small projector comes with a small cooling fan. As a result, you may spare some room, but your video projector will be a little bit noisier. In order not to be bugged by this situation, your projector’s volume level should not exceed 32dB. Sony VPL-HW40ES’s noise level is 21dB.
Quite often, video projectors are quite massive. What’s more, cables and wires clutter up your room even more. Fortunately, the latest models are much more compact. On top of that, they use wireless solutions. One of them is AiO (All in One) video projector.
