All video projectors use a very bright light to project the image, and most modern ones can correct any curves, blurriness, and other inconsistencies through manual settings. lcd projectors are widely used for conference room presentations, classroom training, lcd projectors in hyderabad and live events applications.

1080p projectors are the ideal solution for top of the line home theater performance. When making your choice, consider throw distance and lens shift features (if needed) to make sure the model you want can be installed comfortably into your intended viewing room. All models are sufficiently bright for dark room viewing on screens up to 110″ diagonal. However, some are brighter and can accommodate ambient light or larger screen sizes.

The age of the faulty health class film projector is long behind us, and digital projectors are now the standard. There are giant, professional-grade DLP models, sharp and accurate LCD models, home theatre projectors, home entertainment projectors (there is a difference), and even pocket-sized LED projectors.

But digital projection alone is not enough. There’s HD+, full HD, maximum HD, and WQHD for your consideration. Basically, if there’s a way to ratchet up pixel count and expose the artifacts in whatever dreadfully ancient display you’re using, manufacturers will find a way. And whatever ocular miracle companies build next, the rest of the display tech market will need to keep up. High definition is de rigueur, and even 720p is starting to sound dated.

So why buy a projector that’s stuck in the last century? Whether you’re presenting a Powerpoint deck to clients, teaching fractions to your first-grade class, or screening a movie in your backyard, the projection tech should match the source quality (if not exceed it).

The rule of thumb for theater dark lighting, based on recommendations of The Society of Motion Picture and Television Engineers (SMPTE), it to shoot for 16 foot-lamberts (fL) as the brightness for the screen. For the W1070’s rated 2,000 lumens, using a 1.0 gain screen at 1080p’s 16:9 aspect ratio, that would work out to screen size of more than 200 inches diagonally.

If you need to, you can lower the brightness level to make the projector more appropriate for a smaller screen size by switching to the lamp’s eco mode, using one of the projector’s lower brightness presets, or both. However, the argument for getting this bright a projector in the first place is that you can use it with the lights on. With moderate ambient light, the more appropriate screen brightness for 2,000 lumens would be in the range of 40 fL, for a screen size of about 130 inches.

Basics and Setup (projector dealers in Hyderabad)
Surprisingly small and light for a 1080p 3D projector, the W1070 measures 4.1 by 12.3 by 9.6 inches and weighs just 5.8 pounds. If you don’t want to install it permanently, it’s easy to store it away when you’re not using it, move it from room to room, or even bring it with you to a friend’s house.

The back panel offers two HDMI ports, making it easy to connect to two 1080p sources, plus S-video, a set of three RCA connectors for component video, and the usual VGA and composite video ports. Both HDMI ports are 1.4a, which means they support 3D as well 2D for connections to Blu-ray players, cable and FIOS boxes, and the like.

Setup is standard, with the 1.3x manual zoom giving you reasonably good flexibility in how far you can put the projector from the screen for a given size image. An even more welcome touch is the vertical lens shift adjustment that lets you move the image up or down by about 5 percent of the screen height from its center position.

Brightness, Image Quality, and Rainbows
With its 2000 lumen rating, the W1070 is easily bright enough to throw a reasonably large image that’s bright enough to stand up to a moderate level of ambient light. And note that I measured its color brightness at roughly 80 percent of its white brightness in both its brightest and best color modes. That high a percentage means there’s very little difference between the perceived brightness with a color image versus a solid white screen. It also tends to go hand-in-hand with good color quality.

Along with a bright image, the W1070 delivers image quality that’s just short of excellent. In my tests, the projector did swimmingly with most of the clips that we use to highlight problems. I saw a mild loss of shadow detail (details based on shading in dark areas) in one scene, but it was little enough that I wouldn’t have noticed it if I didn’t know what the scene should look like.

I also saw some annoyingly obvious noise in solid dark areas in night scenes, with the noise not improving at all when I set noise reduction at its maximum. In brighter scenes, however, which would include most video you’re likely to look at, the noise was generally minimal, as is typical for home entertainment projectors in this price class.

Very much on the plus side, color quality was excellent, the projector handled skin tones well, and I didn’t see any motion artifacts or posterization (colors changing suddenly where they should change gradually), even in clips that tend to bring out these problems.

One potential issue, as with any single-chip DLP projector, is rainbow artifacts, with light areas breaking up into little red-green-blue rainbows. I tend to see these artifacts easily. With the W1070, I saw them more often than with most projectors I’ve tested and in scenes that I’ve rarely, if ever, seen them in with other projectors. Depending on how easily you—or anyone you watch with—sees them, you may or may not consider this a problem.
