Projector Screen Rentals

Projector Screen Rentals
By Marcus Peterson

Projector screens are used to project data and video. Screens can be made of material such as the conventional cloth materials like bedsheets, tarp and synthetic material. For informal occasions such as outdoor residential movies, the former are used. For formal occasions and also for movie shows for large gatherings, synthetic white material is used. Sometimes, even walls are used as projector screens.

Projector screens come in various sizes. The screen size depends upon the lens of the projector. For short throw lenses, i.e. the lens that produces the largest image in the shortest distance, big screens may be chosen. This is ideal in a small room gathering. For long throw lens, i.e. the lens that produces small image from large distances, small screens may be chosen. This is ideal for projections from a booth or stall.

Projector screens are measured by the diagonal distance of the image needed. Alternatively, screens can be chosen according to the distance of the projector from the screen. The width of the screen is half the length of the projector from the screen; i.e. if the distance is 16 feet, then the width of the screen is 8 feet.

The screens come as accessories and the rental rate start from $30. Almost all of the projector rental companies have stocks of screens.

The competition to the screen rental comes in the form of residential as hoc screens such as bed sheets and tarp. Bed sheets with a mix of colors are hung to give better picture. Outdoor projector screens are in demand during summer when one would prefer to have outdoor parties. For conferences and meetings, sometimes flat panel displays and plasma screens replace the conventional screens.

Compare LCD Projectors

Compare LCD Projectors
By Ken Marlborough

LCD (Liquid Crystal Display) projectors are devices used for displaying presentations or videos in an enlarged size. They are the modern replacements for slide projectors and overhead projects which were popular earlier.

LCD projectors are available in several variants with differing specifications. Choosing the right projector is as simple as knowing what it will be used for. The two parameters needed to compare an LCD projector are - cost and specifications. Knowing what is needed and how much you will need to use the various features / specifications of an LCD projector are going to be will help one compare the projectors with a better perspective. For this reason, it is important to know the basics of projectors before comparing them.

Aspect Ratio: It refers to the width vs. the height of the projected image. UXGA, VGA, XGA, and SVGA resolution all have a 4:3 aspect ratio.

Brightness: A projector's brightness is measured in lumens. The more light in the room where the projector will be used, the more bright the projector should be.

Contrast Ratio: Is the ratio between the darkest and brightest areas of the projected image. Medium Contrast ratio projectors can be found with a ratio of 500:1 to 1200:1.

Data Signal Ports: These ports on the projector should be compatible with whatever image source they will be paired with.

Keystone Correction: This is the ability to correct the image distortion that is created when a projector is placed at anything other than a 90 degree angle to the screen.

Native resolution: This resolution for a digital projector is the actual number of physical pixels on the projector's image chip.

Projection screens: These screens come in various fabrics and sizes. While it's possible to project the images on a blank wall, the best image quality will be achieved by projecting the images on a good screen.

Video Format Capability: A digital projector's video format capability determines which video format data it can accept. Most projectors will offer all three: PAL, NTSC, and SECAM.

A wide range of desired projectors can be found by giving exact specifications on various website over the internet. Once these basic features of projectors are compared and the best suited LCD projector identified, one can go ahead and compare the prices of the required projector.

How You Can Increase The Lifespan Of Your Projector Bulb Or Lamp

How You Can Increase The Lifespan Of Your Projector Bulb Or Lamp
By Clifford Tan

The replacement of projector bulbs is an all-too-frequent occurrence for anybody that has owned a home theater projector for any length of time. While a two thousand hour lifespan may sound like a lifetime to some people, rest assured it is not long before the projector lamp will need replacing. There are however, some general tips that can help to expand the life of a headlamp for the projection unit.

Do not touch the lamp with bare hands
One of the most frequent problems encountered is people replacing the bulbs with their bare hands. While this is fine for an ordinary light bulb, it is not a good practice for a projector lamp. The lamp in a projection unit burns much hotter than any regular light bulbs. The effects of touching it with bare skin are equally magnified and problematic.

Touching a projector bulb with the bare skin leaves traces of oil on the lamp surface. While this may seem a very minor detail, it is detrimental both to the bulb and the quality of the resulting multimedia display. The oils will get burnt onto the lamp and drastically reduce the lifespan. As the oil is baked into the surface, it actually diffuses the light being projected, reducing the lumens actually being sent to the refractive surfaces. The light will not be enough to project the image that has come to be expected from the home theater projection system. While the problem may not be noticeable at first, over the course of a little time, the quality will degrade to the point of not being viewable.

Turn off the projector power after turning off the lamp
It is highly recommended to turn the power on the projector to the off position only after having turned off the lamp and allowing it to cool. This will allow the cooling fans to do the job they were designed to do. While rapid cooling and heating result in repeated contractions and expansions of the bulb filament, it is much better that it be done more quickly with the cooling fans. Likewise, turning the projector on and allowing the cooling fans to run for a moment before turning on the lamp will help as well. This will add hours to bulb life expectancy and allow for longer hours of viewing pleasure on the home theater projection system.

Constant Movements
Constantly bumping or moving the projector, especially while it is hot can be very detrimental to the projector lamp. The filament in the bulb loses almost all tensile strength when it is heated during normal usage. It is much the same as the filament in a camp lantern. The principle is the same; the filament effectively becomes almost the same consistency as ash, making it extremely vulnerable to damage when it is hot. Even after proper cooling, the lamp filament is very sensitive. Care should be taken when moving the projector for whatever reason. While it is always a good idea to be careful with electronic equipment, some aspects of the home projector are actually a bit more sensitive.

It will usually be necessary to move the projector when cleaning the filters. As always, it is a good idea to move it carefully without jerking it around or bumping it any more than needed. Taking an extra moment or two to check the projector mount and make sure it is still securely fastened can also be beneficial and prevent slips and movement which may otherwise be harmful.

With a little care and a little preventative maintenance, the projector lamps will still need to be changed, but not nearly as often.

Shall We Consider A Cheap Projector?

Shall We Consider A Cheap Projector?
By Clifford Tan

What exactly defines a cheap projector? Different people will have varying opinions in regard to this matter. For some people it implies a lack of quality where for some others, it will mean an opportunity to have high quality at a substantially reduced price. Finding a cheap projector does not require any forfeiture of quality. If it does, then the buyer should beware and shop around more. Cheap projectors are readily available featuring all of the benefits to establish a nice home theater system.

The DIY or Do It Yourself projector is a popular alternative for many people who could not otherwise afford a home projection system. While it does have some drawbacks for those who are not so mechanically inclined, it also has many benefits. If an individual has a rudimentary knowledge of electronics, this can be a good choice. There are many available plans for this type of project. Parts can be a little more difficult to find, but it can be done with a little research and some phone calls. While it is not a fix-all solution, it is a viable alternative if you are looking for a cheap projector.

Online auctions are another way of getting around the high cost of some quality projectors. When looking at auctions, it is best to note details in the description. Avoid any type of auction where any damage may be expressed or implied. There is no need in trying to find a cheap projector that will have to be repaired. More often than not, these projects end up in a closet or garage somewhere and never get finished, usually due to the high cost of fixing them.

It is a wise decision to look for auctions from people who have upgraded their theater systems or otherwise have a reasonable explanation for being rid of the projector. Most online auction sites have contact information available, so if there are unanswered questions, it is best to ask them BEFORE you bid. If the seller will not answer questions or answers them incompletely or indirectly, do not worry. It is probably not a good idea to bid on it either. The seller may often avoid specifics when there is damage that affects the performance of the projector. It is substantially better to lose a bid on a good projector than it is to win a bid on a damaged item. There will always be more auctions and more cheap projectors available.

One category that is often overlooked is a cheap alternative in home projector systems. These are commonly referred to as pre-made projectors. These are usually factory assembled DIY projectors. Often, a company that buys and sells projectors and parts will have better deals than the average person can get by buying their parts in bulk. Some of these companies have people that put together cheap projectors and sell them, generally on the internet, but sometimes on online auctions and by other means as well. If a person is not mechanically inclined, but still wants the benefit of a cheap projector, this is a very good alternative.

Should We Buy A Demo Projector Over A New Projector

Should We Buy A Demo Projector Over A New Projector
By Clifford Tan

After many years experimenting with and learning about home theaters, it is hard not to interject some personal experience into the subject matter sometimes. When I was a teenager, I was piecing together my first home theater projector. I had a state of the art front projector that took up fully two thirds of my bedroom. Intellivision was a modern marvel with 64bit video game technology. Only one thing was lacking, I was buying a new stereo to complete the home theater experience.

There was no way I could have afforded a brand new stereo, but I did, with some patience and searching, I found some demonstration models that were within my meager budget. I completed my first home theater system when I was about 16. Is the demo model still a viable option though? And will it work for home theater projectors in the same fashion?

A fair discount is often given to the purchaser of a demo model. This is done mostly due to the fact that the demo model has indeed been used to a certain extent. While this may not be an issue for some audio and visual equipment, it is necessary to look at the whole picture before deciding if this is the right way to purchase a home projector.

Obviously you must decide if the projector will fit your personal needs. What kind of media display does it offer? Will it be suitable for mounting in your home? Will the cables be included? Is there still any warranty left on the projection unit? Is the projection screen included with the projector? This last part can be especially important since you can be assured that the screen and the projector are fully compatible if the unit has been displayed in the store.

Once all these questions have been answered, even if they are all answered favorably, it is necessary to look at what may be considered the most important two factors to consider when looking at demo models.

The first question to ask is what is the discounted price? While this is usually around ten percent, frequently an otherwise demanding store may be open to negotiations. The second very important question is to get an idea of how much the projector has been run. By knowing this simple fact, you can ascertain roughly how much bulb life will still be in the headlamp.

While it may seem silly to haggle over a light bulb, projector lamps can be a very expensive replacement part, usually costing between a couple of hundred and five hundred dollars each. Is any discount in the price of the home theater projector going to be outweighed by the purchase of a new bulb in the next few months?

With some careful searching and a little patience, a demo model is an excellent and affordable opportunity for the home theater enthusiast, just be careful and remember not only what to look, but what the relevant questions are when you are shopping this way.

Some Things Your Projector Dealer Might Not Tell You

Some Things Your Projector Dealer Might Not Tell You
By Clifford Tan

A salesman is a salesman. He does not make a living if he does not sell something. So it may sometimes happen that a salesman or a dealer will not tell the buyer all of the relevant facts about a given product. We have tried to list enough of them here to give you a general idea of what to look for and what to ask.

Bulbs or the Headlamp
This is probably the one thing that gets overlooked more than anything else. The bulbs are an expensive part of the home theater system and need to be checked out carefully before purchasing a projection unit. What is the projected bulb life? How many lumens does it generate? These are specific questions that should generate specific answers that the projector dealer may not otherwise mention.

Contrast Ratios
Contrast ratios are something else that needs to be considered. The projector dealer may or may not know the statistics regarding a specific projector unit, but what about the ambient lighting in the room where the projector will be used. Is the light source constant or is it varied? Properly factoring in the light source in the room where the theater projector will be set up is not something that many dealers or salesmen will volunteer to do for the buyer.

Screen
The screen is also an important part of the whole home theater experience. Which screens work best with which types of projectors is likely something the salesman or dealer is not going to know and will not tell you without prodding. Having the information beforehand can save a lot of time and grief when shopping for a home theater projector.

Mounting
What types of mounts are included with the projector is something they may or may not refer to at the projector dealer, but what else is there to consider with mounts? Is the projection unit prone to overheating when mounted on a shelf mount? Is it compatible and able to be mounted in the proper place for the distances in the room where it will be used? Another factor in regards to the mounting of the multimedia projector is the hazard of creating a keystone effect by mounting the projector incorrectly or off center. What kind of variance do the optic lenses on the projector provide to prevent this? Is there only a vertical adjustment or does it have both horizontal and vertical optic controls? Does it only have the keystone adjustments or does it provide digital adjustment as well? Mounting the multimedia projector properly is a key factor in being able to properly enjoy a high quality picture with the home theater projection unit.

Is this the right projector for me?
Is the projector really compatible for the uses that are needed or is the salesman or dealer just trying to push a product off on the consumer? Knowing which projectors are better for what types of displays is something that the dealer may not even know about. Different home theater projectors have different uses. Some work better with movies, videos and video games, and some work better for still-multimedia presentations. Being knowledgeable about which projector does what can save a lot of hassling with the uninformed salesman or the dealer who just wants to move projectors out of his store.

To be forewarned is to be forearmed. No matter how well prepared the salesman is or how honest the projector dealer is, they have many different products that they have to know a lot about. Even the salesman with the best intentions will not know everything about all of the home theater projectors available. There are many things the projector dealer will not tell you.
