High Definition 1920x1080 Full HD LCD Panel
Delivers outstandingly crisp, high brightness and high contrast images.
High Purity Colour Filters
The LMD-4251TD uses precisely manufactured RGB colour filters, allowing the reproduction of colours with stunning depth and saturation to create highly natural images.
3D Circular-polarizer System
The LMD-4251TD adopts a 3D micro polarizer filter attached to the LCD panel, and is supplied with circular-polarizer glasses. In this system, the right and left signals are sorted into odd lines and even lines respectively. The right and left images delivered from the LCD panel are circular polarized in different directions through the micro-polarizer filter and the patterned retarder. Each right and left image can then be viewed by the corresponding right and left circular-polarizer filter glass.
Unique Lightweight Circular-polarizer 3D Glasses
Sony BKM-30G circular-polarizer glasses are designed for the 3D production operator’s convenience, and optimized for both LMD 3D monitors.
3D display feature – Horizontal Flip
When a half-mirror type of rig is used, either the left or right signal may be reversed horizontally. The Flip H function turns the reversed image to the normal view. This is helpful because the user can refer directly to the rig camera, achieving a simple and cost-saving system.
3D display feature – Disparity Simulation
Either the left or right signal phase (or both phases) of a 3D image can be shifted horizontally. In this way, users can simulate the amount of 3D image parallax, and can judge whether the camera rig should be adjusted on location or whether it would be better to adjust the parallax later during the post-production process.
3D display feature – Horopter Check
This function helps users to perceive the subtle difference of depth between different objects placed on the 3D screen surface.
3D display feature – Checker Board
Left and right input signals are displayed in a grid pattern on screen – divided into 9 blocks vertically and 16 blocks horizontally. By comparing adjacent images, users can recognise a difference in brightness and colour setting of the left and right images, and thus easily adjust the camera’s white balance and iris settings.
3D display feature – L/R Switch
Left and right signals can be swapped in a moment without inserting black frames, simply by manually pushing a function key. This instant-swap capability enables users to compare whole images and check for any sense of incongruity or for unnatural images.
3D display feature – Payload ID Display
Channel-assign information about the payload ID data of input signals is displayed on the menu screen. This tells users how the left and right channels are assigned in the menu.
Colour temperatures of 9300k,6500k, or a user preset value can be selected.
Accurate and Repeatable Colour Reproduction
ChromaTRU technology ensures close CRT colour accuracy and gamma matching throughout the product’s life and delivers consistent colour temperature across the entire greyscale range. Both control characteristics also assure extremely tight colour matching between different model samples. Three settings are available to simulate EBU, SMPTE and ITU-709 colour reproduction.
White Balance Calibration Function
The LMD-4251TD employs software based white balance calibration function, which is called LMD_AutoWhiteBalance. Combined with a PC and commercially available calibration tool - X-Rite i1Pro - this function enables precise and quick adjustment of the monitor’s white balance.
10-bit Picture Processing
Delivers smooth colour and greyscale transitions for high quality video production.
3G SDI Input
The LMD-4251TD has a 3G SDI input capability. On Sony's montiors, the 3G SDI interface is compliant with the SMPTE 425 standard, transmitting up to 4:2:2/10bit 1080/60P video data using one SDI cable. 3D left and right signals can be handled through a single HD-SDI cable with a 3Gbs data rate.
Multi-Format Signal Support - up to 3G SDI Input
LMD-4251TD can accept almost any SD or HD video format, both analogue and digital. Includes NTSC, PAL, component, RGB, Y/C, 480/60i, 575/50i, 480/60p, 576/50p, 1080/50i, 1080/60i, 1080/50p, 1080/60p, 720/50p, 720/60p, 1080/24psf, 1080/25psf, 1080/24p, 1080/25p, 1080/30p and PC signals from VGA to Full-HD.
