HDMI or DVI input, the DVI output signal will be similarly HDCP encrypted. VP-792 supports Pan, Zoom and Tilt to select a part of the input image, fill the screen and pan within it. System control is via an OSD controlled by keys on the front panel or through the inbuilt TCP/IP Web server.

VP-792 SYSTEM DESCRIPTION 2.1. Product Overview VP-792 is designed to accept the following input signals: YPbPr or RGBS SD and ED and HD component video via 3 or 4 BNC connectors VGA analog (computer interface) via 15HDD DVI (Digital Visual Interface) via DVI-I (only the digital part is implemented on this connector), HDMI is supported via a HDMI/DVI adapter.
2.2.5. Display Output A DVI-I connector is provided which will support DVI outputs as well as HDMI 1.3 with 36-bit video and HD audio formats when connected to a suitable HDMI 1.3 receiver. When the input signal has HDCP encryption, the DVI-D output connector will carry a similarly HDCP encrypted signal. When an HDCP encrypted signal is input, but the display device does not support HDCP, the output image will turn black and a message indicating HDCP Signal will come up to indicate this.
3.2. Introduction The VP-792 units have the input connectors on one side of the housing and the output connector and communication ports on the opposite side. The keypad for controlling VP-792 is located on the input connectors side. The active input is indicated by their corresponding triangles lit green.

A factory reset can also be applied when pressing the factory reset key combination at power up. The keys have to be kept pressed for about 10 seconds until the RGB(S) input LEDs stop flashing. If the keys are released during that 10 seconds period the system will get into Updater mode (see section 5) since the Menu key is part of this key combination.
The list of inputs are: Component, VGA, DVI and Test Pattern. Test patterns can be generated by VP-792 without needing an input connected. When Test Pattern is selected as the input, the required test pattern can be chosen with the menu navigation up and down keys when the menu system has been exited, or it can be selected in Menu>System>Input Config>Test...
3.5.2. Location Settings: Front Tabletop, Front Ceiling, Rear Tabletop, Rear Ceiling The image can be flipped to accommodate different projection scenarios as well as screens mounted upside down. 3.5.3. Optimize for Display Settings: DVI forced, Optimized, DVI/HDMI Internally, the display interface processes data at a full ten bits per color. The color depth on the DVI-D output is determined by the supported standard of the attached monitor or device when set to DVI/HDMI.
Otherwise it is displayed at 50Hz. A 25Hz input mode is output at twice the frame rate 50Hz. An exception to the 24 and 25Hz input mode treatment is if the output resolution is set to 480i or 480p. 480i and 480p are always run at 60Hz output rate. 50Hz input modes are displayed at 50Hz output rate.
3.6. Color This menu contains adjustments associated with setting up inputs to the unit. Use the Up and Down keys to scroll to the required item and press the Menu key. 3.6.1. Black-Level Offset Available Settings: 0 IRE, 7.5 IRE Used to select 7.5 IRE black level set-up adjustment.
16:9 screen. With PC application activated the VP-792 communicates with the PC tool Warp Generator. Warp Generator allows you to define an arbitrary screen in live operation by projecting a grid on the surface and move the grid points to get a rectangular output.
Crop preserves the aspect ratio and scales the image to fit the screen. Dependant on the aspect ratio of the panel either the top and bottom or right and left areas of the image are cropped. Anamorphic scales the input image such that it is displayed with a 16:9 aspect ratio when displayed on the screen.
3.8. Enhancement The enhancement menu provides image enhancement functions. Note that the enhancement settings apply to video input signals only, not computer graphics signals. 3.8.1. Sharpness Available settings: -50 to 50 in steps of 1 Control of the sharpening enhancement filters' levels. These are peaking filters to improve high- frequency response.
The DDC can be taken off line. When setting HDCP Input to OFF VP-792 pretends to be non HDCP compliant forcing the source to not encrypt data which is not copy protected.
By default VP-792 is in auto frame rate switching and I/O lock mode. In these modes the output of the scaler is forced to adopt the sync timings of the input signal...
Factory Defaults This button let you restore all settings to the default values of the VP-792, thus, provide a means to get back to a known (good) system state. A requestor will come up and ask to confirm prior to actual...
When using the Auto Zoom function - Each VP-792 unit gets the same graphics or video input signal through a distribution amplifier. The VP-792 unit cuts out and resizes the image to display the part of the image assigned to the corresponding screen.
Custom Alpha Map menu item becomes available. Custom alpha maps can be uploaded through the Web or remote control API interface of VP-792. The map can be switched ON and OFF. The map is combined with the Align or S-curve map internally generated. If that is not wanted Blend Curve Type has to be set to OFF.
No extra software needs to be installed on a PC. The PC Web browser is used as the graphical user interface for all control items. To connect to the VP-792 the TCP/IP address of the unit has to be entered into the address list box of the Web browser in the following format http://xxx.xxx.xxx.xxx. The TCP/IP address assigned to VP-792 can be found in the System>Network Settings menu.
Test patterns can be created and stored on the PC. Four such custom test patterns can be uploaded to and stored by the VP-792 unit. Each of the test patterns in the four slots can be deleted and replaced by another test pattern.

5.1. Introduction VP-792 has a USB port which allows a PC connection. With the Kramer PC Updater tool new firmware can be installed on VP-792 for feature upgrades and bug fixes. The latest firmware version for your processor is published on our Website. Save the file to your computer.
6.4. PAT Testing Earth continuity testing under PAT regulations shall be done to the VP-792 with 8A or 10A only. A test with 25A may damage the unit. In fact, VP-792 is IT equipment and the IEE Code of Practise to check earth continuity suggests an alternative 20-200mA test.
