This field monitor delivers comprehensive monitoring capabilities for both photography and video production workflows, featuring a large 3840×2160 resolution display with 10-bit color depth processing. The monitor combines the portability needed for field work with the professional features required for broadcast-quality monitoring and critical image evaluation.
The BM281-4KS provides advanced color space management with adjustable color space options including Native, Rec.709, and three user-defined settings for precise color reproduction. The monitor supports accurate color calibration and includes PROLTE version compatibility for ColorSpace CMS by Light Illusion. High Dynamic Range functionality enhances image quality by reproducing greater luminosity ranges, allowing lighter and darker details to be displayed more clearly while improving overall picture quality. The HDR activation provides sharper images with greater detail and richer colors compared to standard display modes.
Built-in 3D LUT functionality enables quick color tone recombination to create different color styles, featuring three user-configurable logs for flexible color grading workflows. The monitor supports loading custom .cube files via USB flash disk for personalized color correction and creative looks. This feature allows cinematographers and colorists to preview and apply various color treatments in real-time during production, streamlining the creative process and ensuring consistent color management across different shooting conditions.
The monitor accommodates multiple input sources including 3G-SDI with loop output, HDMI 2.0 (supporting 4K 60Hz), HDMI 1.4 (supporting 4K 30Hz), DVI, VGA, and Tally connector inputs. Quad view display capability allows simultaneous monitoring of different input signals from SDI, HDMI, DVI, and VGA sources, making it ideal for multi-camera productions and broadcast applications. This flexibility enables directors and operators to monitor multiple camera feeds or sources concurrently on a single display.
The BM281-4KS includes comprehensive camera auxiliary functions for professional photography and videography, featuring focus peaking, false color display, audio level meters, waveform monitoring, histogram display, exposure tools, check field, and image analysis functions. Additional monitoring tools include color space indicators, 3D LUT controls, HDR processing, timecode display, quad view, aspect ratio markers, center markers, and screen markers. User-definable F1-F4 buttons provide quick access to frequently used auxiliary functions such as peaking, underscan, and check field, while a dial control allows precise adjustment of parameters including sharpness, saturation, tint, and volume.
The monitor features comprehensive connectivity with V-Lock battery power connector for portable operation, XLR power connector for studio applications, and VESA 75/100mm mounting holes for versatile installation options. Audio connectivity includes stereo L/R inputs and dual speaker outputs with headphone slot for audio monitoring. The robust construction includes a carry-on suitcase and various mounting accessories, making it suitable for both field production and studio environments where reliable monitoring performance is essential.
Optional tripod mounts available from us significantly expand the monitor’s range of applications.
