Look for in home theater projector - The idea behind this test is, beyond a test of the product in him even, to understand whether it is possible for an affordable budget, replace a HD TV. Whether it's the practical side or side quality, we will try to see what it is.
Projector is a complement to the TV since it can be used as in the half-light, or even better in the dark to give the impression of being at the cinema. In addition, the video projectors work with a consumable: the lamp which has a limited life. On newer models, the life expectancy is slightly higher (up to 6,000 hours in eco mode), 8 years for 2 hours of daily use.
Three technologies dominate the video projectors: DLP, LCD and the SXRD.
This comparison includes all types of video projectors: models Home Cinema, the mpro or even video projecors Coulter and ultra short focal length. There are for all tastes and all budgets.
What should i look for in a projector? The key points:
Ergonomics
It concerns the connection (number of HDMI ports, audio output, USB connectors, etc.), the readability of the interface and the remote control that is here essential, especially when the projector is fixed to the ceiling.
Contrast
Contrast is important because it determines the relationship between the deep black and brightest white. More the contrast, the more the image is dynamic.
Image quality
The quality of the image of a video projector depends on several criteria such as respect of colors, the linearity of the gray levels (average gamma) and the color temperature.
Consumption
Energy consumption is important. Less greedy models of the market fall below 100 W using LED. Lamp more conventional models consume between 200 and 350 watts.
Noise
Noise is a very important criterion since it may be annoying when using. Less than 40 dB (A) noise is compulsory for a minimum of comfort, but it depends on the distance with the projector.
Testing Procedures
Best buy guide led projectors for home theater - We use a very similar to that of televisions, testing methodology since it is the same video analysis software which now comes under the measures: the HCFR colorimeter. We can thus assess the brightness, the depth of black, color space, RGB levels, color temperature, saturation, or gamma curve. In addition to this, practice tests (playback of HD movies, video games, TV,...) allow us to complement the purely technical.
We can also use the hd projectors to watch mega filmes hd 2.0 with better image display.
