![]() ![]() Currently manufacturers are making 4K UHD projectors using either DLP or LCOS chips. They may achieve this either by using imaging chips that have native 3840x2160 resolution, or they may use the new 4K DLP chip which has 2716x1528 mirrors along with a pixel-shifting process that produces two discrete pixels for each mirror.Ī key benefit of the single 4K DLP chip design is that all three color channels are always in perfect convergence, whereas any slight misalignment in any 4K three-chip light engine may affect image acuity. ![]() 4K UHD projectors create the picture on the screen using about 8.3 million addressable pixels. This is a 16:9 aspect ratio format, the same as Full HD projectors and flat panel TVs. Projectors using this format are rare in the marketplace at the moment, and they are only being made with native resolution 4096x2400 LCoS chips.ĤK UHD ProjectorsThe Ultra High Def (UHD) resolution is 3840 x 2160. This is higher resolution in both horizontal and vertical dimensions than UHD, and it also has a unique aspect ratio - 1.71, or slightly less widescreen than standard HD 1.78. In addition, 4K DCI is a standard format for the larger digital cinema projectors being made by Barco, NEC, Christie, Digital Projection, and others.Ī variation of the 4K DCI format is 4096 x 2400, or about 9.8 million pixels. Sony is using the 4096x2160 format in its line of 4K home theater projectors, and JVC introduced it with its first native 4K home theater model. ![]() It has an aspect ratio of 1.90 compared to the standard 1.78 in Full HD and UHD. Projectors using native displays in the 4K DCI format will use a pixel matrix of 4096 x 1716 to display a 2.39:1 Scope format movie, and a matrix of 3996 x 2160 to display 1.85.ĭCI's 4K spec has the same vertical resolution as 4K UHD, but is about 7% wider. This is slightly higher in resolution than the UHD format, which is about 8.3 million pixels. 4K projectors come in several different actual resolutions and aspect ratios as described below.īookmark this page for links to the current and pending production status of all 4K projectors by type, as follows:ĤK DCI ProjectorsThe Digital Cinema Initiatives (DCI) 4K format is 4096 x 2160, or about 8.8 million pixels. As a category of projectors, they generally use in the range of 8 to 10 million pixels to create the picture, compared to the 2.1 million in Full HD. The term 4K in common use refers to a class of projectors that are about 4 times the resolution of Full HD 1920x1080. You can use our Database to track the roll-out and production status of all 4K projectors by type and resolution. 2017 was the year 4K resolution projectors began to hit the market in volume and they are continuing to flood the market at rapid pace in 2018. ![]()
