AT-2151HD+
Category：Monitor
Screen Size：21.5 inch
Features
- Upgrade Version, higher, wider and broader;
- With ultra-high brightness backlight support, the peak brightness can reach an astonishing 2000cd/㎡. 20-level custom backlight brightness adjustment, which can meet the viewing needs of all shooting and application scenarios;
- With HDR display mode, it can not only display the rich levels of brightness and dark parts in HDR video images more accurately, but also make the performance of images more real and vivid under different brightness and contrast conditions;
- It adopts wide color gamut LCD panel, supports DCI-P3 color gamut, and provides more realistic color performance, which is very helpful for film color grading;
- Support one-key light metering function, which can detect the over-standard signal in the screen within one second, and can accurately display the specific position of the over-standard signal.
B/P/D Series Monitor internally built in 3D-LUT Color Management System in accordance with unified industry standards and it uses professional testing equipment to take systematic and accurate calibration for monitors to ensure the display indicator of monitor meet the tolerance range of color space standard .Therefore, it ensures each monitor has the accurate color restoration and the color of same style monitors is consistent to the maximum extent .
Usage:
In order to adjust for correct scanning users can choose different Aspect ratios. Selections are: 16:9, 4:3, Letterbox, Pixel-to-Pixel, Over Scan and Built-in Scan.
16 channels of embedded audio in the SDI video signal can be decoded and 8 selective channels can be shown on the screen at the same time. The Volume unit shows both VU and PPM.
Usage:
The Volume unit is used for measuring audio levels and calibration. This is helpful for making sure that audio levels are within technical requirements and specifications.
When use battery to supply power to monitors, please enter the menu to “Auxiliary Function”. And open “Battery Checker”,
So you will find one Battery meter displayed at the top-right corner, caculating the remaining of battery capacity. When capacity is less than 205，the scale meter color will be changed from Green to Red.
Dynamic Source information embedded in the SDI video signal can be displayed as UMD or IMD. This feature can be turned on and off via the menu.
Usage:
It can be used to supply signal source information from video routing equipment to operators during a live broadcast event.
Luminance levels can be represented using False Color on the screen. It represents the amount of exposure explained as color values ranging from Blue to Green to Yellow to Red.
Usage:
False Color is used to assist in setting the camera exposure. Blue (cool color) indicates a low exposure, a darker blue indicates an even lower exposure. Red (warm color) indicates a high exposure and a deeper red indicates an even higher exposure. Green and Yellow are in between. A scan feature allowing the image to be offset to the upper left revealing the Luminance Waveform on the upper right makes it easy to identify parts of the picture which may exceed standards.
A red peaking filter is used for Focus Assistance. It is represented as a red line around sharp edges. The edge color can be changed if desired; available colors are red, blue, green, yellow and white.
Usage:
Using a red peaking filter aids in the ability to quickly focus or refocus a shot. As the photographer zooms into focus his shot sharp edges will be represented as red lines.
Mono(chrome) displays only the Y portion of the video signal
Usage:
Human Eyes are more sensitive to the luminance signal therefore many viewfinders and small monitors have this function.
Usage：
Overscan is often used to programing for TV broadcast.
Usage:
Image overflow or cutoffs can be checked using this feature. This is helpful during “Pan and Scan” as image is prepped for various broadcast markets. Ruige monitors have selections for Safety Marker Scales, Title Scales, Transform Scales and Center Cross. This is helpful for composition during shooting or title placement.
The luminance waveform can be superimposed over picture (see below). The Y-axis represents the luminance level. There are two indicators; one at 100% and one at 700mv.
Usage:
The Luminance waveform is mainly used to read the value of the Y signal. This is helpful for setting Camera Iris levels.
The zebra is suggested that the photographic exposure is a highlight indicator, and the aperture can be controlled according to the zebra tips when shooting with a manual aperture.
Usually when the brightness of the subject exceeds the maximum brightness (different types of models) that the camera can accommodate (different, this value is different), the zebra is started, so, when the aperture is adjusted, the subject should be the brighteree Slightly with zebras, while other parts have no zebra, which can be accurately exposed. If the spot is too much, the exposure is excessive; if there is no zebra pattern any part of the image, the image will be insufficient. Now some cameras are adjustable, usually adjusted between 60% and 100% of the highest brightness, and can be selected according to their own habits.
