Throw Ratio X Desired screen size (Inches or Centimeters) = Distance from screen (Inches or Centimeters) nnorton00 said:This article has been updated to "Best projectors 2020: Full HD, 4K, portable, short throw". The problem is the #1 projector, the UHD40, has been discontinued since May 2019, over a year! Any other suggestions to replace that top spot?

After resolution and technology, the most important consideration is your room and how you’re going to set up and connect the projector. Here, you need to consider throw distance (how far you place the projector from the screen for a given screen size), optical zoom and lens shift capabilities, all of which will have an impact on projector placement. With its 4,000 lumens brightness spec, this Epson ultra short throw is a perfect option for viewing sports in a well-lit room, and it also has a Yamaha-designed built-in speaker system that creates a strong virtual surround sound effect. Another novelty design that would be great to give as a gift to a young space or dinosaur fan. It's reasonably priced and doubles as a nightlight with a Bluetooth speaker too. The angle and focus can be adjustable as well as a timer. It is quite compact and light, easy to maneuver from place to place. The LS12000 is a beefy (we’re talking 50 pounds) projector with a 3LCD system inside. It provides powerful color and white light output, strong contrast, and no artifacts we could detect during our testing. Its immaculate picture doesn’t struggle to overcome bright lighting conditions, but when we turn out all the ambient light, it steps up to simply blow us away.

This projector has an entrancing mix of blue and green stars and clouds that rotate gently, and the clouds can even be turned off.

We’ve explained the difference between short-throw and ultra-short-throw projectors above, and the screen size will depend on how close you put the projector to the wall or screen. Before you buy, it’s worth thinking about where you can put the projector in your home. There are three kinds of light source. Bulbs, LEDs and lasers. Bulbs are the oldest and cheapest technology, but they can generate a lot of heat and bulbs will need to be replaced fairly often. This home planetarium features a dome inscribed with the constellations, which it projects onto the surrounding walls when you turn on the lights. We were really impressed with the Orzorz Galaxy Night Light when we reviewed it recently. It easily rivals the Sega Homestar Flux in terms of image quality and functionality and comes at a fraction of the cost.We’d describe an “all-in-one projector” as any model that can work without needing any extra bits connected to it. This includes ones that have built-in speaker systems (like several on our list) and an operating system that includes access to streaming apps, so you can use them without having to connect a streaming device or Blu-ray player. Portable Projectors While standing under a dark-sky and looking up at the constellations above is one of the joys of astronomy, it’s not always possible to get out and observe every night through a telescope. Although projector categories change from one manufacturer to another and evolve over time, the application categories are consistent, if somewhat overlapping. Here's a brief look at the most common categories and subcategories of applications, and which features are most important for each. It gets plenty bright enough, has the same maximum image size, and has more ports for connectivity than either of its rivals. Its look may be a little more “old-school VCR” than “sleek and sexy” but we think it’s more than capable enough if you don’t mind its design.

What’s more, the auto-focus and auto-keystone correction features mean you don’t need to spend hours tinkering to get a high-quality image; a real plus with a projector that might not be set-up permanently. Meanwhile, the built-in 15W audio system gives you sound that’s good enough for casual entertainment, if a little brash and shouty if you turn the volume up too high.However, if you’re a gamer and you want to play on the biggest screen possible, there aren’t many better ways to do it than on this potent projector. We test the best 4K projectors in real-world conditions, viewing with both room lighting on and lights off to get a sense of how well the projector performs under a range of conditions. All of our viewing is done using a projection screen, either a matt white material or an ambient light-rejecting screen in the case of ultra short throw projectors. You'll often see projectors with more than one throw ratio listed. This means that the projector has a zoom wheel, so you can change the size of the image. Having multiple throw ratios doesn't change our math; you just have to calculate it again.
