Top 9 Questions About Screen Projectors

Top 9 Questions About Screen Projectors

Q) What does an aspect ratio mean?

A) This is the width of your screen divided by its height. An aspect ratio of 16:9 is the same as 1.78:1 and an aspect ratio of 4:3 is the same as 1.33:1.

Q) What aspect ratio projector screen should I choose?

A) Choose an aspect ratio that corresponds to your projector’s application: for NTSC Video choose 4:3 and for HTDV choose 16:9.

Q) What is a 1:1 project screen?

A) This is a square project screen that is typically used with overhead projectors.

Q) What does “Gain” mean?

A) The term Gain is used to measure the reflective quality of the screen surface. Choose a projector screens with higher gain if the brightness of your projector’s lamp isn’t enough for your room.

Q) What size projector screens should I buy?

A) Unfortunately there isn’t an easy way to answer this question – the size of your screen should be chosen after taking into consideration the resolution and the brightness of your projector, the ambient light in the room, the dimensions of the room, the number of seats and their arrangement, as well as the distance between the screen and the projector.

Q) Do I need white or gray screen?

A) This depends on your particular circumstances, but if you have a relatively new projector and dark home thither room, white screen is probably the better choice. In the case of abundant ambient light that falls directly on the screen, you might opt in for grey screen.

Q) Will roll-up screens develop waves over time?

A Projector screens that aren’t tab tensioned are likely to develop waves over time, but they are also more affordable.

Q) What screen surface should I choose?

A) This depends on number of different factors like ambient light, the projection method, the arrangement of the seats, the brightness of the projector, and the position of the projector among others. Many screen manufacturers have online calculators that will help you choose the best screen surface for your particular circumstances.

Q) How should I clean my projector screens?

A) Refer to the manufacturer’s manual since this largely depends on the surface material. In most instances dry cloth will remove the dust, but if you have to take care of stains, check the manufacturer’s recommendation about the kind of detergent that you can use.…

Setting Up a HD Projector Home Theater System

Setting Up a HD Projector Home Theater System

Many issues must be considered when opting to set up an HD projector home theater system. Factors such as control over ambient light, dimensions of the area that the system will be installed in, the format of the media versus the format that the HD projector is optimized for, connectivity, and optimal sound system setup are some of the major areas that should be researched before installing an HD projector.

Brightness

A projector’s light output is measured in lumens. Most HD projector systems operate in the 700 to 2000 lumen range. However, it should be noted that that brighter is not always necessarily better. Ambient light can have a drastic effect on the quality of the viewing experience. For example, if the ambient light levels in the area are high or hard to control, (daytime outdoors, a room with few curtains), then you will require a HD projector with a lumen rating in the 1500 to 2000 range. Conversely, if the area has a lower level of ambient light, then the 800+ lumen range should more than suffice.

Area Dimensions

Nothing would be worse than purchasing a HD projector that is either too small or too large for the area it is being used in. To combat this, most retailers will provide a screen size calculator. The effectiveness of this tool is contingent upon the purchaser knowing the distance from the front of the projector to the area being projected upon. This value is also known as the throw distance.

Format

Projectors come in two primary formats, 16:9 or 4:3. This is a reference to the aspect ratio. 16:9 is the standard for HDTV, while a 4:3 aspect ratio is used for standard television. It is wise to purchase a projector that is congruent with the signal being projected. However, a 16:9 image projected onto a 4:3 screen results in very little wasted screen space, optimizing the cinematic experience.

Connectivity

Picture quality is determined by the source input. Naturally, an HD projection system is optimized for a high definition input source, (Blu Ray, Playstaion3, or HD DVD/ TV signal source). Keep in mind that most of these sources will require a HDMI cable from the signal source to the projector itself, to work correctly.

Sound

An HD projector is only a projector. Most of the systems on the market do not include any sort of sound system. This means that sound from the signal source will have to be directed into a separate sound system. As most HD projectors are installed in relatively large spaces, a surround sound system that can handle the acoustics of a large area is suggested. Large, vibrant picture, mated with small, inadequate sound is surely an undesirable union.

As the market stands, there are a plethora of manufacturers selling HD projectors. Utilizing the aforementioned guidelines should make the selection/installation process less daunting.…

The Difference Between Switches and Hubs

The Difference Between Switches and Hubs

Even though switches and hubs are both used to link the computers together in a network; a switch is known to be more expensive and the network that is built with switches is typically said to be a bit faster than one that is rather built with hubs. The reason for this is because once a hub gets its data at one of the computer ports on the network, it will then transmit the chunk of data to all of the ports, before distributing it to all of the other computers on that network. If more than one computer on a single network tries to send a packet of data at the same time it will cause a collision and an error will occur.

When there is an error in the network all of the computers will have to go through a procedure in order to resolve the problem. It is quite a procedure as the entire process will have to be prescribed by the CSMA/CD (Ethernet Carrier Sense Multiple Access with Collision Detection). Every single Ethernet Adapter there is has their own transmitter and receiver, and if the adapters weren’t required to listen using their receivers for collisions, then they would have been able to send the information while they are receiving it. But because they can only do one at a time, not more than one chunk of data can be sent out at once, which can slow the whole process down.

Due to the fact that they operate at only a half duplex, meaning that the data may only flow one way at a time, the hub broadcasts the data from one computer to all the others. Therefore the most bandwidth is 100 MHz, which is bandwidth that is to be shared by all of the computers that are connected within the network. Then, as a result of this, when someone making use of a PC on the hub wants to download a big file or more than one file from another PC, the network will then become crowded. With a 10 MHz 10 Base-T type of network, the effect here is to slow down the network to a crawl.

If you want to connect two computers, you can do so directly in an Ethernet using a crossover cable. With one of these crossover cables you will not have a problem with collision. What it does is it hardwires the transmitter of the Ethernet on the one PC to the receiver on the other PC. Most of the 100 Base-TX Ethernet adapters are able to detect when looking out for certain collisions that it is not necessary by using a system called the auto-negotiation, and it will run in a complete duplex manner when it’s needed.

What this ends in is a crossover cable that doesn’t have any delays that would be caused by collisions, and the data can be directed in both ways at the same time. The maximum bandwidth allowed is 200 Mbps, meaning 100 mbps either way.…

Adding Stylish, Elegant Audovisuals to Your Wedding Celebrations

Adding Stylish, Elegant Audovisuals to Your Wedding Celebrations

In the U.S., summer months are by far the most popular season for wedding celebrations. If you’re planning a wedding in the upcoming weeks and months, it’s not too late to add a dramatic and tasteful slide show or photo montage to your nuptial celebration. Here are some excellent tips for audiovisual support during wedding season.

Step 1: Get Started Now

Once you decide to create a photo or video slideshow, go ahead and reserve your rental projector immediately. After all, the only reason to delay this step would be if you were awaiting confirmation on a date, and most folks set their wedding date nearly a year in advance. Reserving a rental projector now means one more to-do item crossed off your massive list.

Step 2: Imagine the Outcome

One of the best ways to create audiovisual support that suits you personally and fits in with your celebration is to begin by thinking about how you’d like it to appear. Does your rehearsal dinner need a slide show to enliven the mood? Does the family of your betrothed wish to get to know everyone better? Do you need some kind of dramatic display at the reception, or the morning-after brunch? A montage can be just the ticket for adding drama, deepening rapport, filling in backstory, or providing a lively focal point.

Step 3: To Help or Not to Help?

Next, consider whether or not you’d like to delegate all or part of this responsibility (or simply collaborate with a partner or two) or handle it yourself. Odds are, there is someone in your family or close circle of friends who has a knack for (and love of) this kind of creation, and they would almost certainly be delighted to assist. Then again, you might prefer to hold the content a surprise and therefore keep it under tight wraps. The choice is entirely up to you, but be sure to consider your skill set – are you capable of putting together the kind of slide show you’ve been envisioning?

Step 4: Creating a Video Montage

This step may be somewhat time consuming, but it is often easier than it sounds. Even a person with no experience in this arena can create a stylish and sophisticated slide show relatively quickly and easily. First, gather all the images you’d like to use. If you plan to use baby photos and other older images, you will need to scan photos to gain digital images. Once you have all your images gathered, begin to put them in the sequence you desire. You may prefer to start with childhood and work your way forward to present day, but this is not absolutely necessary. Once you’ve got the sequence selected, consider what music you’d like to associate with the slide show, and gather those songs or soundtracks. Now you’re ready to begin assembling your slide show, so you’ll need some kind of software, which can be as simple as Microsoft PowerPoint. Add the images, ensure the order is correct, create an opening and closing slide, add transitions, and insert the music. Once you’ve reviewed your slide show and it meets with your satisfaction, burn it to a DVD (it’s a good idea to make at least one backup copy, though you may want a few extra copies for parents and other loved ones) and you are ready to go!

Step 5: Decide on the “When”

Next, it’s time to decide when is the most optimal time to showcase your slide show. For a slightly less formal wedding reception, you might consider letting the images run on a loop throughout the reception. Or, you may prefer to attract everyone’s attention and fun the montage just once during your rehearsal dinner. Depending on who is attending what event, it may be appropriate to run your slideshow more than once during the different festivities. Whatever you decide, it’s a good idea to make some notes about which events and at what point during the events (after the toasts, continuously, during dessert, etc.) you’d like it shown.

Step 6: Inform the Players

The last step is to inform the appropriate personnel about what you’ve decided. For example, tell the banquet coordinator at the restaurant where your rehearsal dinner will be held (and explain that you’ve already arranged for a rental projector, but you’ll need a screen or blank wall), the reception hall, the maid of honor, etc. Lastly, remember to bring the DVD (and a backup, just in case) or entrust this task to your most responsible friend or family member.

Your wedding is the most special time of your life, and when you choose to celebrate the occasion with images and visual memories, trust a reputable projector rental company to supply …

Ford Mustang Lights

Ford Mustang Lights

Do you want to add a little extra flare to the way you ride? How about improving your visibility on the road after a late night, or even making yourself easier to pick out so that your back end of your Mustang doesn’t get smashed in? Obviously we are talking about headlights and tail lights. There are many different directions one can go when it comes to the lighting of a new Mustang. There are HID lights, LED tail lights and 3rd brake lights and projector head lights. All improve visibility and style, which is just as important to most of us.

The ASM HID lights that are just barely becoming available in 2009 are being made with the highest quality materials like imported Philips quartz from holland for the manufacturing of the bulbs. There are a lot of older generation “cheap kits” out there and they don’t really compare to what is being put on the market now by ASM. HID lights are much brighter than the stock halogen head lights and offer up to 3 times the lumens (light output) of the factory lights and increase your visibility dramatically. They give the Mustang a very distinguished look with the headlights and fog lights lit up in a super bright HID light that looks great in the dark.

Installation on the ASM HID headlight conversion kits is simple, using the factory connections and takes about 30 to 45 minutes per set. One set for the headlights, and one set for the fogs. The ASM HID conversion kit uses a direct plug and play install, which fits directly into the headlight housing with no need to cut stock headlight wiring. Installation simply requires connection of the wiring harness to the stock headlight to the bulb’s harness and then connection the wiring harness from the bulb to the HID Ballast. There isn’t any wire splicing it just fits right in. And in this day of conservation the ASM HID head lights will consume about half the power of stock lights (35 watts vs 55 watts) while still dramatically improving the light (by about three times). The ASM Bulbs and Ballasts are also backed by a lifetime manufacturer warranty.

Now for the style end. Recon lighting has just released their mustang line including projector healights, led tail lights and led 3rd brake lights. Installing some LED lights is sure to make you ride in style with cutting edge lighting, which also use much less power than the factory lights. The offer both a smoked lens or a clear lens on the projector headlights, tail lights and 3rd brake lights. They are sealed tight with gaskets to stop internal moisture and vented to prevent high heat damage. The projector headlights are a vast improvement over the stock headlights, and that’s while still using the factory halogen bulbs. they can even be used in conjunction with the HID conversion kits for even more visibility, as long as they are 35 watt HID’s and not 55 watt. The 55’s aren’t legal because they are too bright. Adding a little something extra to your Mustang does not have to be difficult and the benefits of an easy improvement like this make life that much easier and enjoyable on the road at night. Not to mention the comments because of the new menacing look of the lights.…

Which Type of Projector Screen Do I Need?

Which Type of Projector Screen Do I Need?

Most people, when setting up a home theatre projector system, focus simply on the projector and do not give much thought to the type of screen required, which often results in an unpleasant viewing experience. While projecting images onto a wall results in much of the light being absorbed by the wall, a projector is especially designed to maximize the image quality, contrast and sharpness by returning most of the projected light back to the audience.

There are various types of screens available in the market these days, all of which are designed to suit individual needs. The one that will work for you depends on several factors such as the projector format, screen gain, size availability etc. It is, therefore, extremely important to do a thorough research and choose a screen that will give you the best value for money.

Types of Projector Screens

Manual Projector Screens: These types of screens are very similar to window shades, which can be pulled down when required and retracted back into the shell with a simple push. Manual screens are inexpensive, easy to install and simple to use.

Electric projector screens: Also known as motorized projector screens, electric screens work in similar fashion to a manual screen with the only difference being that instead of manually pulling them down the work is done by an electric motor. The stop/start button may be located near the electric projector screens or can also be done remotely, depending on the setup you choose. Motorized screens are costlier than fixed screens.

Portable Projector Screens: Portable projection screens are perfect for people who wish to carry their projectors to meetings and conferences. When choosing to buy this type of projector, it is extremely important to keep the screen case length in mind as it can add a good deal to the screen size. The portable screens are generally available in floor, tripod and tabletop screen variants.

Rear Projector Screens: These screens are generally based on rear projection techniques. In a rear projection screen, the projector is placed at the back of the screen and the images are projected through the screen for the audience to see. These types of screens are seen in theatres or stage performances where people are expected to walk in front of the screen frequently.

Fixed Projector Screen: Permanent or fixed screens are among the more costly options available. As the name suggests, permanent screens cannot be retracted when not in use and are thus seen in places that are designated as dedicated home theatre rooms.…

Tips to Handle Projector Lamps

Tips to Handle Projector Lamps

Projector lamps on a average would last for about 2000 hours and hence when it used for business purpose, 8 hours a day 5 days a week, the projector lamp must last for at least a year. Most of the projector lamp makers provide a RTB assurance for 3 months on new lamps at the time of purchase. There are manufacturers producing projector lamps and more care should be given while selecting a projector lamp.

A qualified professional who knows every thing about projector lamps should be engaged to change a new lamp into the projector housing. While replacing the lamps the terminals should not be over tightened because the ceramic insulation of the bulb can get damaged. At the same time the bulb should be fixed loosely as spark may be produced on the terminal, making excessive load on the ballast which may lead to breakdown of the lamp.

The procedure for replacing the projector lamp may vary based on the manufacturer. Hence the instruction manual should be used and followed carefully to replace the projector lamp whenever necessary. In the instruction manual the set by step procedure will be given to replace the new lamp in the module. Even a qualified person has to go through the manual once to get familiar with the design and model of the projector lamp.

While cleaning the projector a proper cloth should be used for cleaning and especially while cleaning or handling the lamp, all the time a proper cloth should be used. When you clean a lamp with your hand the fingerprints from your fingers will get imprinted in the bulb which may cause hot spots on the surface on the lamp, leading to early failure of the lamp. Air filters in the projector should be cleaned regularly. Poor maintenance of air filters will block the air flowing to cool the lamp and this may result in the failure of the lamp very early. Always there should be proper and good air circulation around the projector to cool it.

Projector should not be switched off by disconnecting the power and always a remote control should be used. When you turn of the projector with remote it will go into cool down mode. The lamp will be turned off and the fan will cool the lamp in a controlled approach. The lamp will operate in very huge temperature and when projector is switched off by disconnected the power the bulb will be cooled unevenly resulting in early failure of the lamp. So it is very important to switch off the power using the remote control as the cooling process will be performed to cool the lamp.

As soon as the projector is switched off it should not moved causing mechanical shock or vibration to the lamp as the lamp filament will be fragile when the projector is switched off. So before moving the projector, allow it to cool for some time. Also you can increase you lamp life by sing the low lamp option if available.…
