The DP-V2420 4K Reference Display is a full-specification HDR reference display compatible with HDR industry standards, helping to meet demanding HDR workflows.
The display facilitates a high luminance performance meeting the requirements of HDR standards, SMPTE ST 2084 and HLG. The DP-V2420 fully covers this range by actual luminance to help ensure that gradation and color can be accurately confirmed.
Canon's LCD technology helps ensure a black luminance superior to that of older CRT displays. Furthermore, video image quality is improved since it demonstrates high gradation performance even at low luminance levels and gradation in shadow areas can be more accurately reproduced without black defects.
To monitor HDR content, two or more gamma curves must be supported. The DP-V2420 qualifies as a Dolby Vision mastering monitor, as it supports SMPTE ST 2084. It also supports Hybrid Log Gamma (HLG), which is in the process of being recognized as a global standard. The DP-V2420 is an excellent choice for either workflow.
The SMPTE ST 2084's dynamic range of 0.005 to 10,000 nits can be displayed as an arbitrary range. This is a new gamma curve developed by Dolby Laboratories, Inc. based on the human visual characteristics called PQ. Luminance up to a maximum of 10,000 nits is treated as absolute luminance. It is currently adopted in Dolby Vision and next generation Blu-ray standard (Ultra Blu-ray) HDR10.
Provided with two gamma settings in the process of being drafted, "Hybrid Log-Gamma" (Y)" and "Hybrid Log Gamma (RGB)".
Video can be monitored at the maximum luminance (peak luminance) supported on the DP-V2420 main unit. HDR image quality can be confirmed at high luminance on the DP-V2420 as an HDR reference display in post-production editing rooms, for example. Even when the area of bright parts of content changes due to switching between individual scenes in films or dramas, for example, changes in the brightness of the overall screen can be minimized. This allows the capabilities of the DP-V2420 to be fully demonstrated in high-luminance HDR production workflows.
In this mode, whatever the luminance of the video content that is being input, video is monitored without altering the luminance of the display main unit. The performance of the DP-V2420 can be fully demonstrated in scenes where shooting conditions during sports and music broadcasts fluctuate in real time due to changing weather and stage lighting even if the camera angle is fixed. This allows high-luminance HDR video images to be monitored without varying image quality at the individual luminance of displayed content, without so-called "loading characteristics."
The DP-V2420 4K Reference Display supports split-screen display of HDR and SDR signals. Since video is displayed simultaneously on the left and right screens, differences in luminance ranges and gradation/brightness can be compared at a glance, thus allowing HDR shooting to be conducted more confidence and efficiency.
Various other features can be combined to make HDR production easier to perform: Range Compression Display according to specific production applications, Clipped Display, Camera Information Display, and Waveform Monitor Display.
The Wave Form Monitor can be selected to display HDR scales (e.g. SMPTE ST 2084 nit) or Canon Log (%) for maximum flexibility in HDR production.
Variable adjustment of the HDR range is possible to suit specific applications. For example, the dynamic range of the HDR standard signal or LOG signal can be displayed to fit within the luminance supported by the display main unit (range compression), or required actual luminance parts of the range can be displayed with the highlight range area excluded (range upper limit clipping). Desired values can also be registered in advance to function or channel buttons. This lets you call up respective HDR standard videos for confirmation by one-touch operation.
Metadata information (color gamut, gamma, maximum luminance, average luminance maximum value of content) from PCs for HDMI-compatible video editing and Blu-ray players, cameras and other devices can be displayed on screen. This is useful for appropriate HDR production since videos can be monitored while confirming the HDR information at the same time.
The DP-V2420 4K Reference Display is an essential tool if you're working in HDR. In a cinema style workflow, its size and capabilities make it versatile enough to use on set on a DIT cart, as a client display or as a close range grading or QC display in post. For sophisticated broadcast workflows, the DP-V2420 will be right at home in your control room or broadcast truck.
The Camera Link-Up feature of the DP-V2420 4K Reference Display allows seamless linking to the EOS C500 and EOS C300 Mark II digital cinema cameras and the ARRI ALEXA SXT camera system, allowing for increased flexibility on-set for camera assistants and DITs.
When a Cinema EOS System camera or ARRI Camera system is connected to the DP-V2420, the camera's metadata can be obtained, and its contents can be displayed. This means that camera set up and confidence checks during shooting can all be done on the DP-V2420 itself rather than on the camera's viewfinder or display. This allows checks without disturbing the operator and increases on-set flexibility. (This feature is available when the SDI RAW format has been selected by Cinema EOS System camera, the 3G/HD-SDI format has been selected by ARRI Camera system.)
An image quality linkup function automatically switches the image quality of the display based on the camera's meta information. This occurs when the Cinema EOS System camera or ARRI Camera system is connected to the DP-V2420. The fact that the image quality settings are linked automatically for the camera and for the display means that setting errors can be minimized.
Presetting by Cinema EOS System's Canon Log/Canon Log2/Canon Log3 and the ARRI Log C video display are also supported. Log C is preset to the main unit menu. So, all you have to do to check image quality is connect the camera- there is no need to add any special LUTs.
The RAW data which is output through the SDI cables from the Cinema EOS C500/C500PL or Cinema EOS C300 Mark II can be debayered in the DP-V2420 4K Reference Display and displayed. The fact that the 4K RAW format image debayering is done in the display unit itself means that there is no need for any external debayering equipment. This enables a 4K-production environment to be constructed with minimal wiring connections. This makes for a more compact camera and display combination and can help increase mobility during shooting.
The DP-V2420 (and the DP-V2410) 4K Reference Display can connect to various color grading systems. For example, while shooting on location you can connect to LiveGrade via a LAN, and manage your color using LUTs and CDLs while RAW debayering is executed. This information can later be transferred to your editing or grading session, helping to simplify your workflow and give you more consistency.
The DP-V2420 4K Reference Display allows you to set multiple LUTs for each picture mode same as the DP-V2410. As a result, users can select up to eight LUTs in one picture mode for improved convenience. In addition, presets from CDL1 to CDL15 and a CDL details setting screen have been added. Users can also change the name settings for CDL1 to CDL15.
The display has an RGB LED backlight and IPS liquid crystal panel, characterized by excellent color reproducibility, in order to achieve the high-image-quality performance that can be optimally suited for on-location work. In addition to satisfying a multiple number of the latest broadcast standards such as ITU-R BT.709, EBU and SMPTE-C as well as the latest DCI-P3 digital cinema standard, it also meets the next-generation standards of ITU-R BT.2020 and ACESproxy, the transmission standards of ACES whose color management standard is advocated by AMPAS.
The DP-V2420 4K Reference Display achieves the same level of high-accuracy uniformity as the DP-V3010/DP-V2410. By incorporating a proprietary image processor developed for use in displays to enable fine-tuned adjustments, color and luminance unevenness on the screen can be prevented and high-accuracy uniformity can be achieved.
The display's 10-bit panel that expresses the shades of each RGB color in 1,024 steps and the high-accuracy display processor enable more accurate gradation displays.
This function allows the display's contrast range to increase from 0-1500 when off, and then from 1500-4000 when turned on.
The DP-V2420's backlight scanning uses a full array RGB backlight, allowing individual backlight areas to be partially turned off includes three adjustment choices (auto, high, low, and off). This feature helps reduce the image-hold period inherent to LED technology while images are being displayed, and results in crisp video playback, helping to reduce the perception of blurring between video frames. It also enhances static image contrast ratio.
The majority of current cinema and commercial production work still uses HD and 2K video. The DP-V2420 is equipped with three types of screen scaling functions, including the Canon Shape Tracing technology™, an original shape-tracing technology that helps to minimize artifacts on images scaled on the DP-V2420. Using the Canon Shape Tracing technology, the DP-V2420 display detects the angles of hard edges and selects an appropriate interpolation to help provide smooth diagonal lines and optimal image rendering, further extending the display's application during location/studio shoots and within color-grading, DI, CGI, VFX and other post-production workflows.
The DP-V2420 4K Reference Display supports the latest ACES2065-1 standard, and has received the ACES logo from the Academy of Motion Picture Arts and Sciences, after review of its ACES implementation. The DP-V2420 is capable of providing RAW format image de-bayering and ACES Input Transform, enabling the reference display to transfer RAW format images to the ACES2065-1 images. These images can be displayed by adjusting the exposure and colors using a CDL's (color decision lists) and by performing ACES Output Transform processing. In addition, by sharing the CDL data using a USB connection, the signals output by on-the-set grading and editing set-ups have the same colors and gradations, so the "look" determined on-set or at an off-site grade can be maintained throughout the postproduction workflow.
