4,000+ lumens – Projectors with this level of brightness are appropriate for the largest meeting rooms, classrooms or multipurpose rooms.These are the typical brightness levels used in classrooms, conference rooms, and home entertainment rooms where you’re unable to block out ambient light. 3,000 – 4,000 lumens – This covers the sweet spot of DLP projectors, in terms of value and features.Under 3,000 lumens – Used in low-lighting environments, these projectors require tightly controlled lighting to eliminate ambient light.Generally, the more people in the room, the larger the ideal screen size. The number of people in a room is a helpful guideline for determining comfortable viewing. The higher the distribution of light over an area, the brighter you’ll need a projector to be. Larger rooms and screen sizes require brighter images. Multi-purpose spaces do well with mid-range brightness, from 2,000 – 4,000 lumens. In darkened rooms, like a home theater, lower brightness (but higher contrast ratios) deliver great results. Viewing spaces with lots of lighting require higher brightness to deliver a sharp, clear image. Factors that influence brightness needs include: Higher brightness also means a higher cost. Environments don’t always need the brightest projector to achieve satisfying results.
Importantly, brighter isn’t always better. The more lumens, the brighter the projector. Projector brightness is measured by how much light the projector can output, called lumens. For business and classrooms, look for contrast ratios in the range of 4,000:1 – 30,000:1. For large venues, like auditoriums, go for the best: 100,000:1.Ī 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 home theater applications, look for a contrast ratio in the range of 10,000:1 to 100,000:1. DLP projector contrast ratios range from 500:1 to 100,000:1.Ĭontrast ratio is an important spec for home theater projectors and high-end use. The higher the contrast ratio, the better the picture quality. Contrast RatioĬontrast ratio compares the darkest and lightest values a projector can produce. DLP projectors must produce the minimum 8 million active pixels required by the Consumer Technology Association (CTA) to qualify as true UHD projection. This is not the same as the ability to reproduce actual 4K images. When comparing 4K projectors some may say they “support” 4K. In turn, they deliver 8.3 million distinct pixels in 4K UHD (3840 x 2160) resolution. Ideal for home theater, 4K projectors are engineered with advanced DLP® 4K Ultra HD chip and XPR technology. The greater the resolution, the better the image quality.ĤK DLP projection is set to explode. For example, a 2K DLP projector has about 2.2 million mirrors. The total number of mirrors corresponds to screen resolution. Think back to the amazing mirror-laden DLP chip. By knowing how you’re going to use a projector, you’ll be able to find the projector that’s right for you. Conference rooms to collaborative classrooms.

Uses range from home entertainment to houses of worship, portable presentations to lecture halls.
Different combinations suit different applications. What to Look for in a DLP Projector: Standard SpecsĭLP projectors come with a dizzying array of features and price points. This can be avoided by installing black borders around the older DLP projector screen. Light leakage: Grey band outside of the image can cause stray light reflecting off the edges of the mirrors on DLP chip.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.Now all of a sudden it Only shows up in a totally different state and with exact name search. Is there something I could do to send signals to Google to show that I am in Matthews, NC?Ģ months ago my listing quit showing up at all unless you typed exact business name What could possibly cause my listing or Google to do this? I have been without my listing for a few months now and have NO calls coming in from it. If you search Locksmith Independence, KS it shows up on the maps. If you search Locksmith Matthews, NC my listing does not show up at all. Keep in mind the GMB is in Matthews, NC All my service areas and the actual map show the correct areas. Now if I search my business name under the auto populate I see it with Independence, KS on the listing. I pretty much do not have any traffic, views or calls now. Posted about my SAB listing a few weeks ago about not showing up in search only when you entered the exact name.
