How to Buy a Portable Digital Projector

Hi, my name is Michael Fallert. I am the general manager of the Sound Shop in Colorado Springs and here today to talk to you about Portable Digital Projectors and what the right choices are and how to make them.
Okay, the first thing we need to discuss is the best one for your needs. Well, there is only couple of choices in Portable Projectors and that is going to be and it is either be an LCD or a DLP projector. Depending on what you need I will dictate that to you. The LCD’s have a lot less moving parts in or much more rugged so if you really, really using on a portable environment where you taking them from PowerPoint to PowerPoint then I would look an LCD. The DLP is going to give you better flowing motion or if you are going to be doing video and activity instead of PowerPoint then the DLP might be a better choice for you.
The LCD on the other hand is going to give you brighter light outputs so if you are going to be in little conference room is doing PowerPoint then you probably going to look LCD’s. As far as what you needs are that is going to be dictated by what environment you are using at in has a rule of from depending on your budget I would buy the brightest projector you can get because it never hurts to have it too bright you can always turn it down. As far as alignment and set up most of them they controls there are be right of the top as well as the remote. You will simple sit them on a conference table, a video stand and zoom focus and aim and you get it on the screen.
LCD displays a liquid crystal displays. What they are is, that was easy way to describe it. Think if it has a small walkman TV, you know the little walkman TVs in a super bright metal highlight bulb behind it shining through it on to a screen. That would be the equivalent of a single element or single panel LCD. Now, digital light projection that is DLP, it works a little different. There is a little micro mirror inside of the projector that is about it big about an inch by three quarter. On the mirror there are 4,400 micro mirrors control by Nano Diodes that reflect that mirror 15 degrees both ways. Then, over here inside the thing is it is hard to keep it simple is a little color wheel was a little pie slices of red, green and blue. The color wheel spins, lights comes in from what is called the light engine of course. It comes off those little mirrors shines through the appropriate slice of pie the exact Nano second to make that one pixel that color, a lot of moving parts. Hence my personal dislike of DLP.
It is a great technology, great device, they work fun but just keep in mind there are a lot of moving parts. That is the biggest different between the two they both do great things. LCD of course can get a higher light output because you does have to worry some so much about the moving parts, about the color will getting hot. All it has is a panel and bulb. They can put as bright above in there as they want as long as that melt the panel you are in good shape. That is why you are going to see LCD projectors are go 4,000 or 5,000 and see a limit which is a major of light output. Where DLP it should down in 800 to 900.
What are the limitation of the portable projector? They are really are no limitation to it other than a fact that they are not tailored for flowing motion video so in other words if you take a home projector like a theater projector and take it to work and do PowerPoint it will do the job not quite as well but it will do it. Now, reverse to that if you take that portable device hanging in your family room with the screen. When you playing high speed sequence is in movie and football and things like that you are going to get a lot of art effecting, a lot of blurring because they are not design to work fast and to refresh those pixels on the screen to keep that video flowing smoothly. That is the biggest difference between a portable device and a home theater device. The theater device is design for that flowing video where is supportable device primarily is done for data pr
