With 240Hz LCD TVs on the market now, the question is whether it’s worth the extra money to make that one of your shopping criteria.

Sure the manufacturers are going to have demonstrations and the numbers to suggest the real-world difference in 120Hz and 240Hz is extremely great. Sure the test patterns specifically designed to highlight these differences suggest that 240Hz is a “must have”, but in regular viewing

The new LED DLP Rear Projection televisions have advanced in so many ways, but one great benefit is that the rainbow effect has been eliminated.

The rainbow effect is what you might expect, a displayed rainbow color pattern. This is best described as brief flashes of perceived red, blue, and green “shadows” observed most often when the projected content features high contrast areas of moving bright/white objects on a mostly dark/black background. The scrolling end credits of many movies are a common example, and also in animations where moving objects are surrounded by a thick black outline. Some people perceive these rainbow artifacts frequently, while others may never see them at all.. This was caused by the color wheel used in the DLP configuration. The color wheel was needed to color the light that was reflected off of the microscopic mirrors that produced the images in DLP.

The DLP system used in Samsung’s (our favorite)  new LED DLP TV sets no longer uses a color wheel, since the LED light sources are colored. There is a much longer lasting, cheaper to operate brighter, vibrant color system that has eliminated the rainbow effect.

Whether you choose a Samsung LED LCD TV, or an LED DLP TV, you’ll be getting the best in television technology.
