Best speaker packages 2020: budget to premium, 5.1 and Dolby AtmosĤK or Full HD: What resolution should you get?. Your best bet is to research reviews of the projector you want to buy before making any decisions. While each technology is different, don’t let that become the be-all and end-all when looking for a new projector. They tend to be bulkier devices and more expensive too. On the other hand, black depth is not as easy to create as with DLPs. LCoS, meanwhile, doesn’t suffer the rainbow effects DLP projectors do and aren’t prone to screen burn-in like LCD projectors. LCD projectors are usually cheaper and don’t suffer from the rainbow effect but can sometimes struggle with motion and have trouble achieving the same depth of blacks as other technologies. DLP projectors are generally brighter and sharper, but can suffer from a ‘rainbow effect’ (where you can see the individual red, green, and blue colours) if the panels aren’t perfectly aligned. Both Sony and JVC use this technology, under the names of SXRD and D-ILA respectively.Īll of these technologies have their benefits and drawbacks. This works in a similar way to DLP, but instead of mirrors it uses liquid crystals to control the light. There is also LCoS projection – 'Liquid crystal on silicon'. Alternatively, three-chip DLP solutions also exist where the light is split and recombined, as with LCD technology, and the need for a colour wheel is eliminated. A spinning colour wheel sits in front of the light source and determines what colour is shown. Each individual mirror can be angled, directing light towards the projector screen or away from it, with each mirror effectively working like a pixel in a television. These images are then recombined in a glass prism to show the full colour spectrum, before they are beamed onto the screen.Ī DLP projector uses a single chip made up of millions of microscopic mirrors. LCD projectors use three liquid crystal displays – each of which handles a primary colour – to project three images, tinted red, green and blue.
