Buying the Right DLP or LCD Projector
Wether buying a new projector or a used NEC LCD Projector, there's a large amount of information to process and this can be a bit overwhelming at times. Today we will focus on just 2 specs, brightness and panel technology type. Knowledge is always a good thing, and we hope that learning about these two parameters will allow you to make the most informed buying decision about your next digital projector.
Brightness or Lumens
One of the first things you might want to compare when choosing a projector is it's brightness. This parameter interacts the most with your projection location, thus the location should be a major consideration in your projector choice and determining the amount of lumens (units of brightness) needed. Also related to brightness and projection environment is adjustability (projection angle and distance), when using portable compact projectors on the go this can be important. Generally, brighter projectors that can put out a higher amount of lumens tend to be more expensive. The following are some rough guidelines for recommended projector brightness levels in lumens. Remember these are only loose guidelines. As technology advances, brighter projectors will be cheaper and the standards will move upwards.
• 3000 plus ANSI lumens and more. Great for outdoor occasions, big theaters or huge screenings, also projecting with the room lights on.
• 1800 - 3000 ANSI lumens. Perfect for classroom presentations and big lectures, high end home theater and TV viewing, DVDs and more.
• 1000 to 1800 ANSI lumens, good for basic entertainment purposes, portable business presentations, static graphics and inexpensive game use.
Projector Panel Type
The two primary types of projectors are those that utilize LCD panels and those that use DLP panel technology. LCD happens to be the most popular technology these days. As the technology is more common and less proprietary, LCD panels like those in the Hitachi LCD Projectors are slightly cheaper than DLP panels. Projectors that use LCD panel technology are also known to have deeper color saturation and generally seem to be capable of greater brightness levels. Keeping the strengths and weaknesses of LCD technology can be very helpful while comparing specs and purchasing an LCD projector.
Projectors utilizing DLP technology can cost the same or slightly more than LCD projectors but are generally thought to produce deeper, darker black levels and higher contrast ratios than LCDs. Home theater buffs also seem to gravitate to DLP projectors for their greater contrast and general ability to project warm, film like images. DLP lamps are believed by some to last longer than LCD lamps. Check out some information on the DLP Home Theater Projector to get a feel for DLP capabilities.
How do I do fractions on the TI-36X II Scientific Calculator from Texas Instruments?
I have no idea how 2 do fractions, and i need 2 know!
thanks! it worked!
i have the Tl-30X ll but i can give it a shot. it a little button that had an A on it. then it has a b/c next to the A. an example to use it is if u have the number 3 1/2 then you put in 3 push the A b/c button then put in the numerator and then push the A b/c again and put in the denominator. hope it helped a little.
