Projector Warranties: Return to Base Warranty
This type of projector warranty is the most basic warranty as well as the most common. The way it works is if the data projector is not working, you have to pack it up and return it to the manufacturer. The manufacturer will repair the data projector and send it back to you. This is not the best warranty because you are without your data projector until they get it fixed and return it to you. The average repair time is 2 to 3 weeks. Plus, you could be looking at a longer wait because the repair parts might be on backorder. Projector warranties can be confusing and can vary greatly from one manufacturer to another.
Projector Zoom Lenses: Manual Zoom Lens
Most projectors have a zoom lens, allowing the adjustment of the image size without moving the DLP or LCD projector. A projector with a zoom factor of 1.2 xs will allow you to adjust the picture by only 20%. Look for a DLP or LCD projector with a higher zoom, as it will allow you to present an image that will match most any screen size. Some zoom lenses are maneuvered manually. For these manual zoom lens projectors, you typically adjust the zoom above the lens.
Projector Warranties: Repair or Replace Warranty
For Further Study..... Simply put, if your LCD projector is not working, an audio-visual technician will try to offer a solution or repair the projector over the phone. Once the audio-visual technician determines what needs to be done, the technician will come to your business to fix it. If the technician cannot fix the LCD projector, the manufacturer will replace the projector with a new one.
Projector Warranties: Projector Lamp Warranty
Lamp warranties range from 30 days to 6 months. If you are putting your digital projector into a rigorous environment, it may be worthwhile to find a projector with a better projector lamp warranty. Also, the some new inexpensive projectors tend to have a very short lamp warranty, as well as repair warranty. Look at this carefully when choosing a digital projector, because the immediate savings may result in a hefty repair cost down the road.
Projector Warranties: Swap out Warranty
This warranty is the best type of projector warranty, but not the most common. If your digital projector is in need of repair, a technician will first determine the problem over the phone. Next, you can send the digital projector to the manufacturer to fix and at the same time, they will send to you a loaner projector to use while yours is being repaired. You usually receive the loaner projector the next business day. The loaner projector is typically a used projector, but it will work well until you get your projector repaired. Obviously, once you get your original digital projector back from the manufacturer, you are responsible for returning the loaner projector.
Disadvantages to Wireless Projectors
With the advantages that wireless projectors offers, there are a few disadvantages as well.
1. With wireless projection, there will be a slight delay when you give the projector a signal.
2. You cannot project full motion video in real time when projecting wirelessly.
3. The wireless projector will cost a little more than an equivalent projector that is equipped with standard cabling.
4. There are possible security issues with wireless projecting.
Projector Warranties: Dead on Arrival Warranty
Several projector manufacturers offer a projector warranty protecting you if you plug in your new multimedia projector and it does not work. This situation is rare, but it does occasionally happen. With the Dead on Arrival Projector Warranty, you simply return the non-working projector and the manufacturer will rush another new model multimedia projector to you.
Projector Zoom Lenses: Digital Zoom Lens
Most projectors have a zoom lens, allowing the adjustment of the image size without moving the DLP or LCD projector. A projector with a zoom factor of 1.2 xs will allow you to adjust the picture by only 20%. Look for a DLP or LCD projector with a higher zoom, as it will allow you to present an image that will match most any screen size. A digital zoom lens on a projector allows you to further move into the frame by having the DLP or LCD projector continually resize the image. It is a nice feature to have in conjunction with manual/power zoom because as you move into the frame, the screen size remains the same.
Advantages of Wireless Projectors
Wireless projectors are becoming more widely available as more people are using wireless in their laptop computers and other technology. The main benefits of projecting wirelessly is as follows:
1. Cabling issues are eliminated which makes your workspace tidier, less confusing, and signal loss through cabling is no longer a problem.
2. Another advantage of projecting wirelessly is that you can switch between multiple PC servers easier.
3. Another advantage of wireless projectors is that the presenter will also be able to have better mobility while presenting without walking around or tripping over wires.

What can CD recorders do? Are they worth the price? What should I look for in a CD recorder?
CD recorders have finally come down far enough in price to make them affordable to the average computer user. The next question that begs to be asked is, "Do I need one?" Now, most computer users would answer "Absolutely, it's the new toy I've been waiting for!" but if you are questioning the necessity of a CD recorder, I can tell you what they do.
Most CD recorders (also called CD burners) fit into your computer in one of the CDROM bays. I recommend installing it in an open bay and keeping your current CDROM. While the CD recorder can act as your primary CDROM, two CD drives can make some other recording features possible.
CD recorders are able to make and copy both data and audio CDs. This means that it is possible to backup your files or make a mix CD of your favorite songs. And because most CD recorders come with Adaptec Easy CD Creator, which comes with wizards to make CD creating easy, people with very little computer experience should have no problem getting started.
CD recorders are also able to copy both audio and data CDs. This is where the second CDROM drive can come in handy. This means that you can make backup copies of both your Windows CD and your favorite audio CD in case they were to get lost or scratched. Please note that copying a CD that you do not legally own or giving away a copy of your CD to someone can be against copyright laws.
The media that CD recorders use is usually referred to as CDRs or CDRWs. CDR stands for CD-Recordable and CDRW stands for CD-ReWritable. CD-R media should work in all types of CD-Recorders, but it takes a CD-ReWritable drive in order to use CDRW media. The great thing about CDRW media is that you can use it over and over again. You can just erase the disk and start fresh. The downside is that CDRW media does not work well for audio CDs. That doesn't mean that you can't make audio CDs with a CD-ReWritable drive, you just have to use a CDR disc.
So now the question is: "What type of CD recorder do I get?" There are a few basic choices that you must make to guide your purchase. First, if you want to have the ability to rewrite to CDs, then choose a CDRW drive, which are a little more expensive, but worth it. Second, the speed of the CD recorder will make a big difference in your satisfaction. Speed is given in the following format: 8X/4X/32X. The first number corresponds to the speed at which it will record. The second number refers to how fast it will rewrite, assuming it has the capability. The third number is how fast it will read off of the CD. The higher the numbers, especially the first one and second one, the faster you'll be able to make CDs.
As far as the brand of your CD recorder, my only suggestion is to buy a brand you've heard of. As is true with all computer products, there are a lot of companies out there making products. You can assume the big name companies will make a quality product, but you don't have that luxury with the smaller companies. Also, the smaller companies will generally not have customer support that is as good as the larger companies.
Buying a CD recorder can be a very fun process. Search around, find a good deal, and make sure to get a lot of media, because you would be surprised how fast they get used up.
