![]() Support for color depth of 8 bpc (24 bit/px) or higher.CEA defines an Ultra HD product as a TV, monitor, or projector with the following characteristics: In October 2012, the Consumer Electronics Association (CEA) announced their definition of the term Ultra High-Definition (or Ultra HD) for use with marketing consumer display devices. In some of ITU's other standards documents, the terms "UHDTV1" and "UHDTV2" are used as shorthand. Īlthough the UHDTV standard does not define any official names for the formats it defines, ITU typically uses the terms "4K", "4K UHD", or "4K UHDTV" to refer to the 3840 × 2160 system in public announcements and press releases (" 8K" for the 7680 × 4320 system). It adopts the same image parameters defined in SMPTE ST 2036–1. In 2012, the International Telecommunication Union, Radiocommunication Sector published Recommendation ITU-R BT.2020, also known as the Ultra High Definition Television ( UHDTV) standard. UHDTV1 systems are permitted to use BT.709 color primaries up to 60 Hz. These are the same characteristics later standardized in ITU-R BT.2020. Colorimetry characteristics as defined in the standard, including color primaries, quantization parameters, and the electro-optical transfer function.Square (1∶1) pixels, for an overall image aspect ratio of 16∶9 : §5.1.The standard defines the following characteristics for these systems: In 2007, the Society of Motion Picture and Television Engineers published SMPTE ST 2036-1, which defines parameters for two UHDTV systems called UHDTV1 and UHDTV2. However, usage of these terms in the cinema industry predates the publication of the DCI standard, and they are generally understood as casual terms for any resolution approximately 2000 or 4000 pixels in width, rather than names for specific resolutions. Some articles claim that the terms "2K" and "4K" were coined by DCI and refer exclusively to the 2K and 4K formats defined in the DCI standard. 4096 × 1716 (CinemaScope crop, ≈2.39∶1 aspect ratio)ĢK distributions can have a frame rate of either 24 or 48 FPS, while 4K distributions must have a frame rate of 24 FPS.: §4.3.1 The resolution of the video content inside follows the SMPTE 428-1 standard, : §3.2.1 which establishes the following resolutions for a 4K distribution: : 6 This specification establishes standardized 2K and 4K container formats for digital cinema production, with resolutions of 2048 × 10 × 2160 respectively.

You’ll still want to make your decision about how much space you have in the room and the distance between where you sit and the screen, but with 3,700 lumens of brightness in tow, LG’s new projectors shouldn’t need the absolute pitch-black settings that previous generations of projectors needed. Now, though, LG’s fighting against the age-old wisdom. Otherwise, in a brightly lit room, you’d pick a 4K TV. a room that you can perfectly control the light to make sure no ambient light seeped in to ruin the contrast - then you’d pick a projector. It used to be the case that if you had a proper home theater room - i.e. Where things get tricky, however, is when you talk about screen sizes larger than, say, 85 inches - that’s where you’ll be spending the same amount of money for a larger OLED or a 4K projector. That simply comes down to the cost of manufacturing - panels are becoming easier and cheaper to produce and the finely tuned components inside a projector haven’t reached the same level of optimization. Whenever you compare them side-by-side, 4K projectors are almost always going to be more expensive than their 4K TV counterparts.
