Sony BVM-E251 24.5-inch TRIMASTER EL™ OLED Monitor

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 colour 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 colour shift depending on the viewing angle has reduced to less than half compared 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.

State-of-the-art product
Super Top Emission technology enhances OLED’s intrinsic benefits to deliver outstanding black performance, a quick response time with virtually no motion blur, and a wide colour gamut. A 12-bit output digital signal processing engine provides a nonlinear cubic conversion colour-management system that delivers precise colour reproduction, stunning picture uniformity, smoother-than-ever gamma performance, and picture quality consistency.

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 Flicker-free mode.

DC Operation
The BVM-E251 can be DC operated. This feature gives more flexibility and mobility to users who want the larger size screen for the on-set application.

ITU-R BT.2020 support for 4K production
BVM-E251 is surely an HD monitor that conforms to ITU-R BT.709 color space. Responding to an increase of the demand of using an HD monitor in a 4K production, BVM-E251 newly supports ITU-R BT.2020 color space and transfer matrix.

Accepts computer signals via HDMI
The BVM-E251 accepts various computer signals input up to 1920 x 1080 through its HDMI connector. It is also equipped with Digital Cinema 2048x1080 signals.

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 colour 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 Flicker-free mode.

Super Top Emission™ technology
Sony's Super Top Emission™ technology has a micro-cavity structure which incorporates colour filters. The micro-cavity structure uses an optical resonance effect to enhance colour purity and improve light-emission efficiency. In addition, the colour filter of each RGB further enhances the colour purity of emitted light, and reduces ambient light reflection.

Ultimate Sony display engine
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 colour management system.

Multi-format signal support
The BVM-E251 monitor can accept almost any SD or HD video format, such as analogue composite video, HDMI and SDI, and variable computer signals through HDMI.

Auto White Balance
The colour temperature and white balance of BVM Series monitors can be automatically adjusted by the Auto White Balance function using specified colour temperature probes, such as

  • Konica Minolta: CA-210, CA-310, CS-200,
  • DK-Technologies: PM5639/06, 
  • X-Rite: i1 (Eye-One) Pro and i1Pro2.
  • Photo Research: PR-655, PR-670 
  • Klein: K-10 
  • 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, conversion errors, etc.

Low video delay
The BVM-E251 display engine ensures a picture delay that is less than one field.

Panel calibration
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.

Colour feedback system
Using a colour feedback system, the BVM-E251 monitor achieves the stability required for broadcast critical monitoring applications.

Interlaced display mode
Faithfully reproduces interlaced signals, emulating CRT monitors.

Picture & Picture mode
The unique Picture & Picture function of the BVM-E251 allows 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.

Scan Switch
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 withoutchanging 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).
