Just In: The DIT House is now renting Sony's Brand New OLED Monitor, the PVM1741


Sony PVM1741

The PVM-1741 “All in one” OLED picture monitor delivers unparalleled picture quality with high-value performance features and functions, all in a compact design. Sony’s 17-inch Super Top Emission OLED display panel benefits from superb black performance, wide colour gamut, and quick response with virtually no motion blur. By combining the Sony OLED display panel (Full HD, 10-bit driver) and Sony’s OLED processing technologies, the PVM-1741 OLED monitor delivers groundbreaking picture quality.

  • The PVM-1741 has an external remote control capability for input/output signal selection and adjustment of various items via Ethernet (10BASE-T/100BASETX) connection.
  • The PVM-1741 monitor employs a software-based white balance calibration function, which is called AutoWhiteBalance. Combined with a PC and commercially available calibration tool*, this function enables simple adjustment of the monitor’s white balance.
  • Quick Response with Blur-free Motion Because the OLED Electro-Luminescent layer inherently responds to any electrical current input, it emits light immediately. By this mechanism, excellent quick response characteristics can be achieved in fast-motion images. This efficient, blur-free, fast response benefits a variety of applications and scenes, eg. in sports broadcasting, monitoring of camera panning and text scrolling.

Details of the Sony PVM1741:

Sony OLED with Full HD and RGB 10-bit driver

The PVM-1741 OLED panel features a Full HD resolution (1920 x 1080) and RGB 10-bit driver together with Sony’s Super Top Emission OLED display panel to create life-like and smoother-than-ever gradation from dark to bright portions of a scene such as in a sunrise or sunset.

TRIMASTER EL design architecture

TRIMASTER Technology is a design architecture used to bring out the full performance capabilities of professional flat-panel displays. It comprises the core technologies that enable the highest level of colour accuracy, precision imaging, and picture-quality consistency. EL (Electro-Luminescence) is an ideal display device of self emission with high dynamic range and high picture quality. With the new "EL" device refining the "TRIMASTER" technology, Sony now re-defines the professional industry with "TRIMASTER EL" line ups.

Superb Black Performance

Thanks to the Sony OLED display panels, the deep black can be accurately displayed and the black portion of an image is not raised.

Wide Colour Gamut and High-Purity Deep Colour Reproduction Sony

OLED is a display device with a wide colour gamut offering not only colour gamuts of broadcast standards (ITU-RU BT.709, EBU, SMPTE-C), but also offers the widest colour gamut of the Sony OLED panel Sony’s Super Top Emission technology is using micro-cavity and colour filters. Sony’s micro-cavity structure uses an optical resonance effect and its colour filters enhance the colour purity of each RGB colour. This combination is also effective in reducing ambient light reflection, and consequently deep colour reproduction can be achieved without colour degradation, even in bright environments.

Quick Response with Blur-free Motion

Because the OLED Electro-Luminescent layer inherently responds to any electrical current input, it emits light immediately. By this mechanism, excellent quick response characteristics can be achieved in fast-motion images. This efficient, blur-free, fast response benefits a variety of applications and scenes, eg. in sports broadcasting, monitoring of camera panning and text scrolling.

Superb Uniformity

The PVM-1741 monitor incorporates a newly-developed OLED processor to bring out the full performance of the Sony OLED panels. This OLED processor offers superb uniformity across everywhere on the screen. At the factory, the OLED panel uniformity is precisely measured and corrected using a sophisticated RGB LUT (Look-Up Table) adjustment system.

I/P Mode Selection

The PVM-1741 monitor provides three I/P modes so that users can select the most suitable mode for each purpose: INTER-FIELD: This mode interpolates images between fields. This is used for picture quality precedence (eg. to reduce the jagged effect on moving pictures). FIELD MERGE: This mode combines lines alternately in odd and even fields, regardless of picture movements. This is used for PsF (Progressive Segmented Frame) processing and still image monitoring. LINE DOUBLER: This mode interpolates by repeating each line. This is used for editing and monitoring fast-moving images and checking line flicker. The minimum processing time is less than one field (0.5 frames).

Lightweight Compact Design – Flexible Styling For Picture Monitoring

The PVM-1741 incorporate a lightweight, compact metal body, and its style can flexibly be changed according to the user’s application: a desktop with standard stands, or with an optional stand SU-561, or without a stand for wall application. The monitor supports VESA mounting of 100 mm pitch and an EIA 19-inch standard rack with rackmount bracket. These features are flexible for a variety of users applications, such as desktop editing, office viewing, monitor wall in studio-sub and installing in OB Vans.

Alexa "High Speed" 120fps with 5.0 Update Packet

DIT House


In response to feedback from end users and the rapid take-up of the ARRI ALEXA camera system on professional productions of all kinds, ARRI has created a High Speed mode that allows the ALEXA family of cameras to run from 60 to 120 fps with Apple ProRes codecs, using newly released Sony 64 GB SxS PRO cards that offer a write speed more than twice as fast as the current 32 GB cards.

The 120 fps feature will become available with the upcoming release of ALEXA Software Update Packet (SUP) 5.0 and the introduction of Sony’s new 64 GB SxS PRO cards. Like the ALEXA anamorphic de- squeeze feature, 120 fps functionality can be activated with the purchase of a license. Each license is coded to a particular camera and can be enabled by copying the license to an SD card and loading it into the camera. Licenses can also be disabled, allowing rental facilities control over which cameras are sent out with the High Speed mode.

Arri releases Software Update 4.0 firmware for Alexa

DIT House


Today, Arri released a new software update for the Alexa camera. New features and improvements include:

  • Customized looks to be applied to all ALEXA outputs via an ARRI Look File
  • AUDIO Playback from SxS Pro Cards
  • SxS recording can be turned off
  • Auto white balance
  • False color exposure check for Log C images
  • Anamorphic de-squeeze
  • More silent operation at higher ambient temperatures
  • 'Rec Low' fan mode for silent operation in extremely hot environments
  • Peaking focus check in EVF-1 and MON OUT
  • RETURN IN video
  • Compare stored image from SD card with live image
  • Master/Slave lens motor control
  • 3D lens sync
  • Lens Data System (LDS) info display in EVF-1 and on MON OUT

As for the new "Arri Looks Files" feature, this a great new addition to the camera's output monitoring. ARRI Look Files are editable XML files that contain a number of parameters including the ASC CDL primitives slope, offset and power. They can apply a customized look to all outputs (EVF-1, MON OUT, REC OUT and/or ProRes) that are set to either Rec 709 or DCI P3. ARRI Look Files can be created with the ARRI Look Creator software, which is a new Mac program developed by ARRI that will be released soon. Various third party companies are also working on ARRI Look File compatible applications, including The Foundry, Gamma & Density's 3CP, Pomfort and others.

One of the most critical items in this update is the "Removed Adaptive De-saturation (ADS)". An image processing step, called adaptive de-saturation, has now been removed. This step was necessary before SUP 3.0 in order to prevent color clipping in highlights. With the introduction of the new color processing in SUP 3.0 it was found that adaptive de-saturation is not necessary anymore, and in some cases even resulted in image artifacts and slight hue shifts. While this will make no difference to most images, color or saturation of highlights might be different from SUP 3.x. We recommend that you shoot test images before you switch during a show from SUP 3.x to SUP 4.0.

Another cool feature that was added is the "Compare Stored Image from SD Card with Live Image". Now, a JPEG image can be loaded from the SD card into the camera and displayed on the EVF and MON OUT. This can be a JPEG that had previously been grabbed with the ALEXA, but it can also be any JPEG image. JPEGs should be 1920 x 1080 for best image quality, or if not, at least have a 16:9 aspect ratio. ALEXA will try her utmost to scale images that are not 1920 x 1080. It is then possible to compare the stored image with the life image. There are two modes for comparing: Interleave and Toggle. Interleave will create an interlaced image from the stored and the live image, alternating line by line between the two. Toggle switches between the life image and the stored image each time the Toggle button is pressed.
