There are several draw backs to Projectors that affect their ability to display clear, crisp images. projectors have to transmit the image to a projection screen; the image then has to travel to the viewer's eyes. HD video is becoming support HD, where as many projectors are still SD and won't display HD images at their full resolution.

The Clarity of LED screens is the main reason why they are supplanting projectors as the top choice of visual technicians. Every bit of distance matters when you're talking about bright, clear visual information. Because LED walls are their own source of light, the images they present appear crisper and more vivid to the viewer.

Projectors tend to suffer a noticeable decrease-up to 30%- in brightness in the first year of use, are not as capable of high contrast, and have difficulty displaying deeply saturated colors. LED displays don't suffer from the same decrease in vibrancy. Also, Projectors still have difficulty displaying deeply saturated colors like blacks, and their contrast is not as great as that of LED displays.

Especially when there's ambient light, such as at outdoor music festivals, ballparks, stadiums, and fashion and auto shows, the light of projectors is measured in lux, which gauges reflected light. LED walls are measured in NIT, a measurement of direct light. One NIT unit is equivalent to 3.426 lux-basically, this means that a unit of NIT is much brighter than a unit of lux.

Projectors are limited in how and where they can be used. You have to have a large screen and an unimpeded space between the screen and the projector. The projector has to be mounted high up and in the back of the room or display area, an it has to be connected to a video source. Anything that gets in the way-can become an obstacle.

LED walls are thin, relatively light, and can be dismantled and moved into a new space more easily than projector displays can. They are simpler to install and quicker to power up. This means more flexibility and fewer venue restrictions when setting up your display. The modular nature of LED panels means unlimited arrangement flexibility and design creativity.

With projector displays, you often have to send them in for repairs, resulting in downtime and un certainity over what the problem is.

Repairing an LED wall is easy. Usually all you need to do is update the programming software, or just replace the module, SMPS or controller with a new one.

Projectors have parts such as bulbs and light engines that require replacement every few years, and those parts aren't cheap: a new bulb alone can cost up too high. All in all, given the continual upkeep required by projector systems and the increased power they consume.

LED walls will cost about 15% to 20% more upfront than projectors, for a similar image size and quality. LED walls also require less power than projectors - about half as much, saving you energy costs. LED walls cost more money up front , the break-even point between the two systems is about 2 years, meaning you will ultimately save money in the long term with LED walls.
