3D Features
Circular-polarizer 3D system
The LMD-4251TD and LMD-2451TD incorporate a
micropolarizer filter attached to the LCD panel. Wearing
Sony’s BKM-30G or BKM-31G 3D glasses, users experience
smooth, uninterrupted viewing of multiple monitors and flicker-
free 3D images. This image quality helps users to engage in
3D production operations with minimal stress.
Unique lightweight circular-polarizer 3D glasses
Sony provides two types of 3D glasses: the standard BKM-30G,
and the clip-on BKM-31G.
BKM-30G and BKM-31G circular-polarizer 3D glasses are
optimized for LMD-4251TD and LMD-2451TD 3D monitors.
These 3D glasses are extremely lightweight*
1
and comfortable
to wear. Designed with a soft frame and center-support
structure, BKM-30G glasses fit any size and shape of head and
face, so the wearer experiences minimal stress even during
continuous production tasks. The center-support structure
of the BKM-30G does not put the lenses under stress, and so
there is no lens distortion. With clip-on BKM-31G 3D glasses,
the wearer can simply flip up the lenses when not required.
Both the BKM-30G and BKM-31G block approximately 99% of
the sun’s ultraviolet rays.*

*1 BKM-30G glasses weigh approx. 18 g; BKM-31G glasses weigh approx. 16 g.
*2 These circular-polarizer glasses cannot be used as sunglasses.
The blocked spectral range is 280 nm to 380 nm.
Fully compatible with 2D monitors
The LMD-4151TD and LMD-2451TD monitors are equipped with
consistent quality, functionality, and operability – essential for
professional monitors. Both 3D monitors can be used as 2D
monitors, and their features are fully compatible with those of
current LMD-51W Series monitors.*
* The LMD-4251TD does not support 2-channel audio level meter and
waveform monitor display.
3D Features
Sony offers two models of high-performance professional 3D LCD monitor: the LMD-4251TD
(42-inch*

Multiple 3D input signal formats and interfaces
The LMD-4251TD and LMD-2451TD accept a variety of 3D signal
formats including 3G-SDI, Dual-stream HD-SDI, HD-SDI side-by-
side, HD-SDI Line interleave (line-by-line), HD-SDI Field sequential
using an optional BKM-250TG 3G-SDI input adaptor, and
DVI Line interleave (line-by-line). This input flexibility enables
versatile 3D production both in the studio and the field.
