![]() These will certainly be recognisable to anyone who's used Video Essentials before. Amongst other test-patterns are the cross-hatch and screen-size, for which Kane was responsible. On which subject, the menu's configuration options cover rear/front and ceiling/desktop mounting.įor calibrators, a 'color pattern' feature switches in various colour filtering. This shouldn't pose too many problems as far as the average UK viewing room is concerned - these things tend to be mounted towards the back of the room on the ceiling. To get that 100in 16:9 image the projector needs to be between 3.8m and 5m (depending on how the lens' zoom lever is set) away from the screen. Samsung states that the SP-A800B has been 'designed to show images optimally on a 100-120in screen' - and funnily enough, my Unity-gain One fitted the bill nicely. Setting up the projector is straightforward. Irritatingly, there's no 12V trigger for motorised screens and so on (surprising, given Joe Kane's home-cinema credentials) although a RS232 serial port is provided for system integration. You get a pair of HDMI ports able to accept 1080p24 (or lower) sources, two component ports (1080i or under), S-video, composite and - for those who appreciate the big-screen PC experience - a VGA input. The optical path on either side, meanwhile, consists of a 300W lamp and an adjustable zoom lens capable of producing images between 40in and 300in in size.Ĭonnectivity is good. That single 0.95in 1920 x 1080 DC2 chip is complemented by a six-segment colour wheel. The SP-A800B does, however, incorporate a variable-iris system ('DynamicBlack') to improve contrast ratio and black level.Ĭlearly at this price level, you shouldn't expect a three-chip projector - and indeed you don't get one. And, although the DC2 is inferior in terms of black level relative to the DC3, designer Joe Kane has expressed the opinion that the older technology fares better when it comes to shadow detail. Similarly as we have seen, upscaled DVD is not the same (maybe close) as native 1080p Bluray.Given its futuristic appearance, it may come as a surprise to learn that the SP-A800B is based around the now ageing DarkChip2 chipset rather than the more recent DC3 or latest-generation DC4.Īccording to Samsung, the latter wasn't available when the projector was designed. In reality, they can never be quite the same as native 4K. With good video upscalers in 4K projectors, upscaled 2K Bluray material may look better than 2K. This leaves us with only 2K Bluray source materials at the moment. ![]() Outside the US, however, such internet delivery system may not be adopted because of filesize and broadcast regulations. Sony meanwhile has been working on a server delivery system in the US. But this may take one or two years before we can see it implemented on 4K UHD projectors.Īs has been said, 4K source material is an issue, since no one has yet finalised on the best format. HDMI 2.0, in brief, will offer a larger bandwidth to support the many enhanced features of 4K UHD, such as higher refresh rate, better 3D performance, increased bit depth, expanded colour space and colour resolution. Just that it limits 4K UHD to only 2160p 24-30Hz. ![]() Well, current HDMI 1.4b can still be used for 4K UHD projectors with HDMI inputs. Coming, as I understand, is HDMI ver 2.0 for 4K.Ī forum member asked me today while at my shop, what the significance of HDMI 2.0 is for 4K UHD.
