What You Need To Know About Resolution Before Renting Or Buying A Projector

Last year there were a lot of resolution advancements, and along with it came major price changes in the projector world. Entry level projectors are now starting from as low as $300, but now the 1080p models have dropped in price tremendously as well. You can pick one up for well under $2000.

The lowest end projectors today will have a resolution of about 800 x 600, and can be bought for next to nothing. But these projectors aren't really good for a whole lot, and their pictures aren't even close to satisfying. These projectors account for a very small amount of sales, and are generally the ones you see used in elementary schools. Every current computer now has at least XGA resolution, and so are most tablets on the market like the iPad and most of the Android models. So if you are looking for crisp image reproduction, especially with small text and graphics, you need to make sure that your projector at least has XGA resolution or higher.

If you are looking for a projector for your business, you would benefit greatly from getting at least an entry level XGA resolution model or a widescreen WXGA model projector. This is the bare minimum that you should be using in order to deliver a professional presentation. If your budget allows, you could however step up to an SVGA projector with a higher brightness, or one of the many affordable 1080p models that are currently available.

For short term use for special projects, spending this type of money isn't really a great option. Instead of investing money in an outdated model that is going to deliver poor results, you can always consider a projector rental. Projector rentals are very affordable, and the staff will be able to answer any questions that you may have and be able to help you choose a model that will deliver the results you are looking for in order to make your presentation perfect in your specific setting. Even if you don't understand the details of projector technology, buying or renting from someone who knows what they are talking about can benefit you a great deal more than jumping blindly into an expensive investment.

Student Performance Increased by 3D Projectors

Some people think that 3D projectors are simply for entertainment purposes, that they hold no real value outside of watching a movie or playing a video game in the third dimension. However, recent studies have discovered that this is entirely inaccurate. New research is showing that the use of 3D projectors, along with other 3D technology, in the classroom is improving the concentration and test results of students.

This new research is being carried out by the International Research Agency at the bequest of Texas Instruments. Texas Instruments has invested a lot in classroom technology through calculators alone but is also one of the foremost chip technology experts in the world. In addition to that, the company saw the introduction of 3D projectors and 3D glasses to class members that were participating in the research.

The International Research Agency monitored the students and discovered that 86% of them achieved better results in the post-test than they did in the pre-test when using 3D technology. It was also discovered that only 52% improved in the control classes, or the classes that were only given 2D technology for the post-test.

In the 3D in Education White Paper, Professor Anne Bamford, who is heading up the research, stated, "Individuals improved test scores by an average of 17% in the 3D classes, compared to only an 8% improvement in the 2D classes between pre-test and post-test. The teachers commented that the pupils in the 3D groups had deeper understanding, increased attention spans, more motivation and higher engagement."

Moreover, the research also studied classes in seven countries across Europe that are adopting the 3D technology. These countries included the United Kingdom, France and Sweden. The studied surveyed 740 students in 15 schools and involved 47 teachers.

3D projecting may still be a primarily entertainment-driven market, but the potential for some serious classroom benefits are evident. I mean, an 86% increase is substantial at any level and it will be interesting to see what other findings the International Research Agency and Texas Instruments uncover.
