24.5-inch TRIMASTER EL™ reference monitor, with 2nd Gen OLED. Dramatically improved viewing angle for critical picture evaluation in the studio and on-set.
For professional applications such as color grading, high-end editing, broadcasting and scientific research, Sony’s leading edge Organic Light-Emitting Diode (OLED) technology and signals processing technology ensures absolutely outstanding performance with the BVM-E251. The color shift depending on the viewing angle has been reduced to less than half that of the 1st generation OLED panel. It allows several people to evaluate the image with extreme accuracy at the same time, increasing the monitor’s versatility in top end monitoring solutions.
Flicker free mode
ITU-R BT.2020 support for 4K production
Accepts computer signals via HDMI
Superb picture performance
Sony TRIMASTER EL™ technology combines the ultimate performance of Sony OLED display with the highly sophisticated TRIMASTER™ technology to provide the highest level of picture performance:
Wide viewing angle
Accurate Black Reproduction
High purity and accurate color reproduction
Quick response time with virtually no motion blur
Very high contrast ratio
Flicker Free Mode
The TRIMASTER EL OLED panel’s superb quick response and scan-driving performance deliver stunning picture quality with virtually no motion blur. However, there is a possibility that flicker is just visible especially when a lower frequency signal is displayed (24p, 24PsF, and 50i). To remove visible flicker, the BVM-E251 is equipped with a Flicker-free Mode.
Super Top Emission™ Technology
Sony's Super Top Emission™ technology has a micro-cavity structure which incorporates color filters. The micro-cavity structure uses an optical resonance effect to enhance color purity and improve light-emission efficiency. In addition, the color filter of each RGB further enhances the color purity of emitted light and reduces ambient light reflection.
Ultimate Sony Display Engine
A high-precision signal processing engine has been developed to fulfil the reference monitor criteria and is optimized to maximize OLED panel performance. This engine incorporates 12-bit output accuracy at each process and provides both a high quality I/P conversion algorithm and a highly accurate color management system.
Multi-format Signal Support
The BVM-E251 monitor can accept almost any SD or HD video format, such as analog composite video, HDMI and SDI, and variable computer signals through HDMI.
Auto White Balance
"The color temperature and white balance of BVM Series monitors can be automatically adjusted by the Auto White Balance function using specified color temperature probes, such as
Konica Minolta: CA-210, CA-310, CS-200,
X-Rite: i1 (Eye-One) Pro and i1Pro2.
Photo Research: PR-655, PR-670
Jeti: Specbos 1211"
High Quality I/P Conversion Technology
The BVM-E251 monitor uses a sophisticated I/P conversion technique that keeps artefacts that are often seen in flat panel displays to a minimum such as edge jaggedness and conversion errors etc.
Low Video Delay
The BVM-E251 display engine ensures a picture delay that is less than one field.
Every BVM-E251 monitor is carefully calibrated at the factory on an individual basis, providing a high level of accuracy and stability for characteristics such as gamma and uniformity.
The unique Picture & Picture function of the BVM-E251 allows the simultaneous display of two input signals on the monitor’s screen. This function is extremely convenient for making instant adjustments to two input sources. Four modes are available to provide users with enhanced operational flexibility: Side by Side, Wipe, Butterfly and Blending.
Pixel Zoom Mode
A selected area of the displayed picture can be enlarged on a pixel basis, up to eight times in size both vertically and horizontally.
Gamut Error Display
BVM-E251 master monitor incorporates a Gamut Error Display function that detects irregular signal input.
S-Log3 and S-Log2 EOTF
BVM-E251 master monitor incorporates EOTF tables to reproduce images captured using S-Log3 and S-Log2. S-Log3 and S-Log2 are techniques used in Sony’s digital cinematography cameras that allows the full latitude of the camera sensor to be maintained throughout the production chain.
2K Picture Resolution
The 2048 Image Slide function of the BVM-E251 allows 2K resolution (2048 x 1080 pixels) images to be mapped, pixel-to-pixel, on the full-HD (1920 x 1080 pixels) panel without picture degradation. The monitor is equipped with a slide function that allows the display of missing pixels in native mode from the left and right part of the picture.
The Scan Switch function allows switching between under scan (-3%), normal scan (0%) and over scan (5%).
Native Scan (Pixel-to-Pixel Display)
The Native Scan function is a unique display mode that reproduces images without changing the input signal’s pixel count.
HD Frame Capture Mode
The HD Frame Capture function of the BVM Series allows a picture frame from the 3G-SDI and HD-SDI input to be captured and saved as a picture file on a USB memory media (BKM-17R) or a Memory Stick™ media (BKM-16R). This picture file can be used as a reference for various purposes, for example, for picture-tone adjustments between past images and for camera-framing adjustments.
Separate Control Unit with USB Memory Slot
A separate BKM-17R Monitor Control Unit is available for the BVM-E251. It is equipped with a USB Memory slot enabling users to download and save all monitor set-ups such as input channel configuration, control preset adjustments, white balance settings and maintenance parameters.
Centralized Monitor-wall Control
The BVM Series monitors and the BKM-17R Monitor Control Unit are equipped with an Ethernet port, allowing remote control of display parameters across a standard Ethernet connection. One BKM-17R Monitor Control Unit can control up to 32 BVM monitors.
The BVM-E251 can be DC operated. This gives more flexibility and mobility to users who want the larger size screen for the on-set application.
Character Off Button
To facilitate parameter adjustments, the On-Screen Menu indication can be taken off the screen while in Menu mode. The On-Screen Menu indication can be toggled on or off with the simple press of a button on the BKM-17R’s front panel.
Copy Function for Monitor Setup and Adjustment Data
The optional BKM-17R Monitor Control Unit includes a USB Memory slot to save and load monitor configuration and adjustment settings. This is useful for multiple monitor systems, allowing the transfer of one monitor’s setup and adjustment data to another. This data can also be transferred via the BVM’s Ethernet connection.
+12dB Chroma UP Function
A Chroma UP button located on the front panel of the BKM-17R allows the chroma level to be boosted by +12dB. This is a convenient feature for adjusting camera white balance with a higher degree of accuracy.
BVM Series monitors can display various markers, including an aspect marker, safe area marker and center marker. In addition to this flexible selection of marker types, detailed display settings of each marker are offered. For example, the color, brightness, horizontal/vertical position and width of aspect markers can all be controlled, while the height and width of safe area markers can be adjusted.
The aspect ratio can be switched between 4:3, 16:9, 2.39:1 and 1.896:1 depending on the input signal.
Wide Variety of Functions
The user has a wide variety of over 40 functions to choose from. Each of these can be assigned to any of the 16 function buttons (F1 to F16) on the BKM-17R controller. Press ENTER to display the F1 to F8 (or F9 to F16) button assignments on screen.
Simply assign a STATUS to one of the function buttons (F1 to F16) on the BKM-17R Monitor Control Unit. The user can instantly grasp the whole monitor status and configurations without having to search through menus.
