DLP projectors

DLP projectors

DLP, or digital light processing, uses tiny mirrors to reflect light toward the screen (an “on” pixel) or away (an “off” pixel). Most models use a color wheel — literally a spinning wheel with color filters — to create sequential color. Some high-end models use three DLP chips; one each for red, green, and blue. DLP projectors range in price from a few hundred dollars to tens of thousands, and more. Most projectors in movie theaters use DLP. You can find models from Optoma, BenQ, Mitsubishi, and many others.

Advantages of DLP projectors

DLP projectors offer road warriors and home theater enthusiasts many advantages:

  • Portability: DLP projectors tend to be smaller and easier to transport given one chip versus LCD’s 3 panels. DLPs using LED or pico technology are even more portable and can connect to smart phones, tablets and other mobile devices.
  • Higher Contrast: DLP projectors’ deep blacks achievable make them popular for home cinema applications.
  • Reduced Pixelation: DLP projectors have a muted pixel structure when viewed from a normal viewing distance, which may not affect a PowerPoint presentation, but will affect smooth video presentations.
  • Reliability: DLPs have fewer parts and are less expensive to repair – sealed optics are good for dusty environments.

Disadvantages of DLP projectors

The few disadvantages of DLP projectors are:

  • The Rainbow effect: Looking away from a projected image on older DLP or from one side of a screen may have “rainbow” effect, or moment of rainbow-colored stripes around brighter objects.
  • Light leakage: Grey band outside of the image can cause stray light reflecting off the edges of the mirrors on DLP chip. This can be avoided by installing black borders around the older DLP projector screen.

What to Look for in a DLP Projector: Standard Specs

DLP projectors come with a dizzying array of features and price points. Different combinations suit different applications. Uses range from home entertainment to houses of worship, portable presentations to lecture halls. Conference rooms to collaborative classrooms. By knowing how you’re going to use a projector, you’ll be able to find the projector that’s right for you.

Resolution

Think back to the amazing mirror-laden DLP chip. Each mirror creates one pixel. The total number of mirrors corresponds to screen resolution. For example, a 2K DLP projector has about 2.2 million mirrors. A 4K device about 8.8 million. The greater the resolution, the better the image quality.

4K DLP projection is set to explode. Ideal for home theater, 4K projectors are engineered with advanced DLP® 4K Ultra HD chip and XPR technology. In turn, they deliver 8.3 million distinct pixels in 4K UHD (3840 x 2160) resolution.

When comparing 4K projectors some may say they “support” 4K. This is not the same as the ability to reproduce actual 4K images. DLP projectors must produce the minimum 8 million active pixels required by the Consumer Technology Association (CTA) to qualify as true UHD projection.

Contrast Ratio

Contrast ratio compares the darkest and lightest values a projector can produce. The higher the contrast ratio, the better the picture quality. DLP projector contrast ratios range from 500:1 to 100,000:1.

Contrast ratio is an important spec for home theater projectors and high-end use. For home theater applications, look for a contrast ratio in the range of 10,000:1 to 100,000:1. Bigger is better. For large venues, like auditoriums, go for the best: 100,000:1.

A high contrast ratio is less critical in classrooms and conference rooms, as the benefits are most noticeable in highly light-controlled, pitch-black rooms. For business and classrooms, look for contrast ratios in the range of 4,000:1 – 30,000:1.

Brightness

Projector brightness is measured by how much light the projector can output, called lumens. The more lumens, the brighter the projector. Importantly, brighter isn’t always better. Environments don’t always need the brightest projector to achieve satisfying results. Higher brightness also means a higher cost. Factors that influence brightness needs include:

  • Ambient Lighting. Viewing spaces with lots of lighting require higher brightness to deliver a sharp, clear image. In darkened rooms, like a home theater, lower brightness (but higher contrast ratios) deliver great results. Multi-purpose spaces do well with mid-range brightness, from 2,000 – 4,000 lumens.
  • Room/Screen Size. Larger rooms and screen sizes require brighter images. The higher the distribution of light over an area, the brighter you’ll need a projector to be. The number of people in a room is a helpful guideline for determining comfortable viewing. Generally, the more people in the room, the larger the ideal screen size.
  • Under 3,000 lumens – Used in low-lighting environments, these projectors require tightly controlled lighting to eliminate ambient light. Ideal use: home theater.
  • 3,000 – 4,000 lumens – This covers the sweet spot of DLP projectors, in terms of value and features. These are the typical brightness levels used in classrooms, conference rooms, and home entertainment rooms where you’re unable to block out ambient light.
  • 4,000+ lumens – Projectors with this level of brightness are appropriate for the largest meeting rooms, classrooms or multipurpose rooms. DLP projectors in this range produce a crisp, clear image, even on larger screens. This enables ease of viewing with larger audience sizes. Ratings higher than 4,000+ lumens are considered high brightness projectors and are used in high-end commercial installations.

Best DLP Projectors of 2021:

1. Hisense 120L9G 4K UST Triple-Laser Trichroma Projector

Hisense 120L9G 4K UST Triple-Laser Trichroma Projector

2. Optoma P2 Black CinemaX 4K UHD 3000 Lumen Ultra Short Throw Home Cinema Laser Projector

Optoma P2 Black CinemaX 4K UHD 3000 Lumen Ultra Short Throw Home Cinema Laser Projector

For starters, the P2 offers a dynamic contrast ratio of 2,000,000:1 versus the P1s 1,500,000:1. With the same 3,000 lumens output as it’s predecessor, the increase in contrast means that the image maintains its brightness but with a 25% wider color spectrum.

One major change in design to the P2 is its color wheel. As both the P1 and and P2 use Digital Light Processing (DLP for short) to produce their image, they utilize a color wheel that spins rapidly to produce its final color display.

New technological developments have allowed Optoma to reduce the size of this color wheel from 8 segments to 6 segments. The new wheel omits the yellow section, and concentrates solely on red, green and blue. By reducing the size of the wheel by 25%, colors appear more vivid, natural and accurate. The P2 achieves this without any drop in brightness.

Another change in design is that the P2 is a white projector & soundbar, whereas the P1 was black. For those who still prefer black model, Optoma offers their flagship model the CinemaX Pro. The P2’s audio portion remains identical to the P1’s exhibiting the acclaimed NuForce 40W Dolby Digital 2.0 soundbar with 2 full range speakers and 2 woofers.
