Will a projector work well on a light blue wall?
I would advise against it. Projectors are not really for the casual user...They are more difficult to set up and get right than a TV is, they also require more time for set up tweaking and adjusting in order to get the image to come out satisfactory ...First many have no sound or sound that is designed for vocals only...Also no TV tuner...Keystone capability is something you should also look into before purchase. Connections are limited so if you want to connect a cable box, game machine and Blu ray player not possible all at the same time, unless you also have an AV Receiver......Also cable runs will be longer and more difficult to deal with all the wires involved...Home Theater Projectors are made for the enthusiast that wants a movie like experience and is willing to pay for it and go the extra mile...There are also Class Room Projectors and Business projectors that you could use but the image quality is not as good and they often have their limits when trying to adapt one for home theater use... ...There are tweaks that can be made to improve the use factor but it doesn't sound like you are willing to try any of them as your just looking for a quick inexpensive solution....The reality is that good projector quality cost more than good TV quality and is more difficult to do...
Can use a projector on a black wall?
get a piece of muslin from the fabric store--you can get a 3 or 4 yard piece of 90" muslin for less than $15--it's what we use as a screen and it works great. black wouldn't be good...you wouldn't be able to see anything...as far as putting up the screen--it depends on how long you want it to stay up and what you have available on the wall--we have a heating duct and we use magnets--in the past we have used industrial strength velcro (it worked for a while) prior to that we used a shower curtain liner (we got the muslin so our screen could be larger) other options are plain white flat sheets (they come in various sizes and can be quite inexpensive)
Can I Use a Projector on a Colored Wall?
I am thinking about buying a home projector for my basement. The one I am looking at getting is the Optoma HD180 from Costco: (http://www.costco.com/Browse/Product.aspx?Prodid=11543258&whse=BC&Ne=4000000&eCat=BC|90607|90613&N=4047294&Mo=14&No=2&Nr=P_CatalogName:BC&cat=90613&Ns=P_Price|1||P_SignDesc1&lang=en-US&Sp=C&topnav=). Being in our basement, it can be made very dark if need be, but the main issue I'm concerned about is the effect the color of the wall will have on the image. It is a dark purple (http://www.ninjalawfirm.com/images/carpet.jpg matches the color very well). It is very smooth as far as I can tell, and I'm not looking to repaint the entire wall, which was just painted not too long ago. Will the color of the wall compromise the image? Should I repaint it white or black? Or will it being dark purple be okay?
Does a wall have to be white to use a projector or could it be any light color?
For best results and a clear vivid image you do not want to use a painted wall as your background. Most off white walls are too noisy with regard to the photopic reponse.i.e diffused lambertian response, specular reflection, and haze come to mind. Couple that with a reflective index of .55 vs. .99 (in most cases) you will not be happy with the color or overall contrast for your projector. That reflective index effects the overall contrast of your image exponentially. Case in point use a good projector screen, even a cheap model will give you a HUGE improvement in overall quality.
Could there be a projector that fills a wall while being an inch away from the wall? Where do the difficulties in getting this to happen lie?
Assuming the wall in question has a larger area than an average size TV, the problem would be matching a lense and the angle it projects in relation to the wall. Also, the projector would be in between the viewer and the screen if it's just an inch away from the wall so that makes it seem unpractical at best. However, imagine a projector somewhere around the edge of the wall and the problem, again, is the lens but then also the distortion caused by the angle of incidence.
Can you use a projector to project green on a wall then have that be used effectively as a green screen?
In theory yes. In practice, if you are projecting green on a white wall, you’ll have to deal with spill from the light spilling from the other lights you’re using. And sometimes we use green lights to light a green wall, which is a similar idea. But spill from white lights illuminating your subject will likely also wash out the green on the white wall—Unless it is far enough back that you can completely block those lights from striking the wall.However there is a way to do it, but instead of a white wall you use a highly refective front projection screen, such as Scotchlite from 3M. This is the same thing as the reflective tape used in clothing and on highway signs. If you project a green light from the same point as the camera lens, that light will hit the screen and be reflected straight back to the lens. The light is actually quite dim, ( a green LED ringlight around thelens can be used) so it doesn’t illuminate the subject with green light that you can see, that is overpowered by your subject lighting.You can experiment with this on your own, but there are companies such as Reflecmedia that make kits for this you can buy too.

How does a pull-down projector screen work?
We have seen this projector screen many times in your life, ever wondered how this cool stuff actually functions? First time, the Pull down screen when we saw might be in our school days. When the teacher who used to teach us grab the white canvas type of material on top the board and with a rattling sound pulls the canvas down and fit it with a nail like structure to not it let go to its original position.The sound which we used to hear is of the spring which is attached in the rolling bar which is on top of the board where the projector screen is rolled. The structure has a spring which helps the screen to wrap up to its original position.With the evolution the screen now a days have been evolved to provide a base to project a crispy high resolution images. Projector screens like Manual Grande Series have Bead chain clutch system which allows it to smoothly roll up and down, also the surface of the screen is also advanced and it is now projection friendly in which the surface tackles the light and gives you a clearer view of the projection.
Can you project a movie onto a brick wall?
They do it on TV so yeah it's possible.
How does a "ultra-short throw" projector work?
When looking at projectors, the word ‘throw’ is what is one of the most important things to evaluate. ‘Throw’ refers to the distance you need to throw the image between the projector and the screen, for the display size of your choice.The throw can hence be determined by the kind of lens in the projector. Long throw projectors need at least six feet of distance between screen and projector, and the lens is of a cheap quality since it does not require a large amount of craftsmanship and amount of glass.Ultra-short throw projectors, on the other hand, have no such limitations. They defeat even short throws, who need 100 inches to 4 feet of distance between the screen and the projector – and can throw the image on the wall that it’s almost touching. It’s akin to a point and shoot, giving you projections 80 inches from the intended surface. Their lenses, naturally, are more expensive to craft and make.An obvious edge to this is also that is nearly eliminates shadows that occur when people walk in between the screen and projector – or other extraneous objects, for that matter, while giving you crisp, clear imaging. Of course, they are a tad bit more expensive – but work impressively in the long run, while having a great amount of utility.To check out some ultra-short throw projectors that are worth a look, I’ll recommend Ricoh’s range: I’ve found them to be quite remarkable in terms of tech and affordability.
