Laser light source projectors – typically combined with a three-LCD image engine – deliver the best contrast and brightness but cost anywhere upwards of £2000 and often significantly more. If you want the very best quality, however, a laser light source projector is what you want. Some people are less sensitive to this than others, though, so if you haven’t experienced a DLP projector, make sure you get a demo before spending your money. As most display colours sequentially use a spinning, segmented colour wheel (there’s the odd exception to this rule), they suffer from what’s called the “rainbow effect”, where small areas of the image appear to splinter into small rainbows when you shift your gaze from one side of the screen to the other. Of these, DLP projectors are the most common, the most compact and tend to deliver the most bang per buck, while LCD projectors tend to be bulky and slightly more expensive.ĭLP projectors do have a downside, though. Most modern home-theatre projectors are based on one of two technologies: DLP and LCD. What’s the difference between DLP and LCD projectors? Even then, you might find it a challenge. ![]() Purists will tell you that these aren’t really 4K, but the technology has reached a point where it’s near impossible to make a distinction – unless you have native and 4K enhanced models running side by side. However, there’s a growing number of “4K-enhanced” projectors, such as the BenQ W2700 or the Optoma UHD38m, which simulate 4K by using pixel-shifting techniques with a 1080p resolution panel. True 4K projectors with a native 4K resolution still carry a high price premium, with even the cheaper options coming in somewhere north of £3,000. If you want a 4K projector, then expect to pay more. ![]() As such, they might be fine for showing PowerPoint slides or streaming Netflix in the garden, but for sports, games and home cinema use, you really need to be able to watch 1080p content at the native resolution. You will come across plenty of cheaper office or portable projectors, but they’ll have limited resolutions of 800 x 600, 800 x 480, 1,280 x 720 or 1,024 x 768. If you’re looking for a projector to watch movies, then make sure the model you buy is Full HD (with a resolution of 1,920 x 1,080). However, there’s a whole world of technology inside these often plain-looking boxes.įirst, resolution. To the untrained eye, one projector usually looks much like another.
