quot; Five tricks color saturation Projector failure

Projector color cast because

With the projection technology continues to mature in the hands of users projector shadow is mainly digital projector LCD projector. However, when using this type of projector, issued projection color often encounter the problem, which causes a decrease in projection effects. So why failures occur projector cast color, we find a failure, how quickly you respond? Believes the information in this article below will give you a satisfactory answer!

Color cast cast by

Under normal circumstances, the LCD projector through the system of internal optical processing will be light, "is break "in the red, green and blue beams of light, the beam of light transmission after three colors, respectively, the AD conversion, modulation and other processes, appears in the three liquid crystal panel, and then through the control unit optical path to achieve the normal color of the light of the last three color light projection prism beam synthesis, the formation of the color image output through the projector lens in the projector screen. And projectors Digital DLP through the red, green and blue color wheel technology of processing color image projection, the projection degree of fidelity DMD micromirror projector color is closely related to the number of how many. If the agreement through the projector's optical system, the output of.

Three color light projection in a particular one or a few colors, the image will appear in the display color cast obvious failure. Obviously, the reason leading to the displacement caused by the color of projection, the projector is the internal system of optical processing, for "external" interference, you can not correct the color processing of the image, and "express", but of course there is no "external force" includes a number of factors caused by different factors in projecting color saturation need a different approach to solve.

Color cast cast of real

Units have Hitachi projector, the "service" time for almost two and a half faster. More recently, I do not know why, through the projector images projector screen a total sensory colored cast phenomenon. Cause at first I also thought of being cold, and do not mind this phenomenon, but in the days after the projection, guilt still can not remove the color saturation, it is clear that the projector is really sick. In desperation, I decided to look into the projector for a thorough examination.

First, connect the projector and computer lines were checked and found that with the projector connected to the computer is a Celeron 733 desktop Founder, will be to connect the projector and the internal computer VGA cable and the mixture was carried out, leading to a phenomenon projection serious signal interference? first anyway, or the first VGA interface cable at both ends removed to see! was the author of an event and quickly meter, in addition to the VGA cable on both sides of interface, and signal lines each were examined, the results did not find cable signal hinge broken and short of that failure.

Projector or to verify if the fault signal line, the author also used a VGA cable to the projector and other connected equipment back on, they found the projector on the projection screen output phenomenon not only is there no screen color cast, and the results seem very clear, very clear line of VGA data projector with the Okanagan is normal, the problem is most likely connected to the projector before the computer platform caused Founder. So the author of the computer that provides Founder checked to see if the computer display settings resolution, if the projector in the support, as I open the Display Properties settings Founder Computer window, find the team of "color" parameter is set to 16 colors of Color "resolution screen "parameter will become the" 800x600 "" Update the resolution "parameter is set to 75 Hz, each parameters compared with the relevant technical indicators projector, projectors founding team found support for all displays parameters, indicating that failure is a projection of color cast caused by a computer Founder himself!

One result of these efforts in a preliminary analysis of some this way: VGA cable and the projector itself is normal to connect the projector is normal Founder computers, the configuration of projection screen settings are correct.

Best projector for us

by Cheryl Feng from CA, AZ USA on 2010-01-21
This projector performs well. Outstanding short throw. We use it in a 70 foot deep by 28 foot wide classroom with the projector screen on one of the 28 foot walls. The projector needs to be about 1.5 feet from the screen to project a 6 foot wide image. NEVER have a problem with walking between projector and screen. You will need to place the projector at approximately the same height as the bottom of the screen. Image is clear and bright, even with full ambient lighting. Lightweight..2 video inputs so we can switch from computer to computer.Really like the ability to "mute" the projection.Have used for 165 hours.Only drawback is it has a larger footprint.Recommend putting a no-slip carpet backing between projector and table to prevent slippage.

Almost ideal mobile projector

by D. Bhayani from on 2009-01-23
This projector offers all the connectivity, including built-in speaker for HDMI input and makes it an ideal projector to connect to portable video devices w/o speakers. It's light weight and small form factor and including case is good as you don't have to shop for one more item!Picture quality is good for the category this projector fits in (720p).Main negative is NOISE, Fan is loud if you are in a quiet environment or doing slide presentation. Even in economy mode, noise is too much. They could have used less powerful lamp (2000 lumens is a lot) and run the fan quieter.


Excellent projector

by SreeV from NJ USA on 2008-11-17
Works very well and the picture quality is great. The wide screen format matches my laptop's native resolution. Automatic keystone adjustment is awesome and works so well (just aim the projector at screen at any vertical angle and the picture is always rectangular)

Great HD projector!

by Alan D. Ohashi from Boulder, CO USA on 2010-06-14
I purchased this projector to show digital movies at the Cheyenne International Film Festival. It performed flawlessly. For the money, it is a great item. The only issue I had was trying to hook up a monitor to the VGA/RGB port and I had no luck with that. Maybe someone can give me a hint about that.
