MVGD 1319 display The MVGD 1319 is an 19-inch grayscale LCD display with a native resolution of 1280 x 1024. Its high-brightness, combined with image crispness and excellent viewing angle, makes it an ideal solution for a multitude of medical applications and environments. Long-term stabilization The display contains a Backlight Output Stabilization system (BLOS©), which continuously stabilizes the luminance output of the LCD’s backlight. This improves the overall optical efficiency and provides longterm image confidence. Ambient Light Compensation (ALC) When enabled, the ALC system automatically adapts the display light output, depending on the ambient light in the room. The ambient light is measured by the ALC optical sensor located at the front of the display. Power saving The display is equipped with a power saving system. When left idle for a certain time, the computer connected to the display, will power down the display. The power saving system can be switched on or off using the on-screen display. The power saving system works with the standard Windows power saving and with the DPMS function on the Barco BarcoMed display controller (if installed in the PC). 12 Overview Parts, controls and connectors Front 3 1 2 Figure 1 1. Ambient Light (ALC) sensor. When ALC is switched on, the display light output is adapted automatically, depending on the ambient light measured by the sensor. 2. Power LED The LED is off when the display is disconnected from the power. The LED is also off when the LED function is disabled in the onscreen display (OSD). The LED is green when the display is on (when enabled in the onscreen menus). The LED is orange when the display is in Stand-by power-saving mode. 3. Control wheel The control wheel can be pressed like a push button and rotated like a knob.

In most cases, no adjustments are necessary when a digital video signal is connected and selected. However, if necessary, you can perform manual adjustments. Please refer to the description of the OSD functions further in this manual. Adjustments for an analog video signal What to adjust if an analog video signal is connected and selected? The first time you connect an analog video signal to the display, you need to perform the Autosetup function (see below). Additionally, if necessary you can also perform manual adjustments. Please refer to the description of the OSD functions further in this manual. 27 Operation Autosetup adjustment When do you need to use the Autosetup function? • The first time you use the display with analog video connected. • After connecting or selecting another analog video source (e.g., changing the PC resolution). • In case you notice the image geometry or positioning is not as desired. Required test pattern To obtain good results, the image on screen during the Autosetup function should meet the following requirements: • The edges of the image should have an intensity of at least 15% video amplitude. E.g., a Windows desktop pattern would be a good image, provided the background is not too dark. • The image should contain sharp black-white transitions, like a line pattern or characters. • The image should contain parts that are completely black (0% video amplitude) and parts that are full white (100% video amplitude). To perform Autosetup: 1. Rotate the control wheel to display the on-screen display. The Main Menu appears. The Autosetup menu is selected. 2. Press the control wheel to enter the Autosetup menu.

Name Description Full Perform all Autosetup functions (below) one after another Phase Adjust the video sampling phase automatically. This is necessary when you notice vertical or horizontal banding or noise in the image. Geometry Adjust the image geometry automatically. This function displays the complete active video in the center of the screen. If the video resolution is smaller than the native panel resolution and no scaling is selected (see further), it puts black borders around the active video window. If the video resolution is larger than the native panel resolution and no scaling is selected, the edges of the image will be lost. Gain Offset Adjust the video levels (black and white) automatically When do you need to use the Autosetup function? • The first time you use the display with analog video connected. • After connecting or selecting another analog video source (e.g., changing the PC resolution). • In case you notice the image geometry or positioning is not as desired. Required test pattern To obtain good results with the Autosetup functions, it is necessary to have a good image on which to perform the functions. E.g., a maximized Windows Explorer window would be a good image. 30 Operation • Geometry: The edges of the image should have an intensity of at least 15% video amplitude. . • Phase: The image should contain sharp black-white transitions, like a line pattern or characters. • Gain Offset: The image should contain parts that are completely black (0% video amplitude) and parts that are full white (100% video amplitude). Contrast Contrast adjusts the brightest elements in the image on the screen, while the darkest elements are not adjusted. Note: Adjusting contrast may affect the number of grayscales in the image. If the contrast is too high or too low, some bright or dark elements in the image may become invisible. To select the center position of the adjustment (value 127), click and hold the control wheel for a few seconds. Brightness Brightness adjusts all levels in the image on the screen, from dark to bright. Note: Adjusting brightness may affect the number of grayscales in the image. If the brightness is too high or too low, some bright or dark elements in the image may become invisible. Instead, if you feel the image is too bright or too dark, try adjusting the Luminance (see further). To select the center position of the adjustment (value 127), click and hold the control wheel for a few seconds. 31 Operation Luminance Luminance adjusts the overall luminance (light output) of the display. It does not affect the grayscales of the image on the screen. When Ambient Light Compensation (ALC) is switched on, the (manual) luminance adjustment will not work. Instead, the OSD shows ‘ALC Active’. ALC can be switched on/off in the Settings menu (see further). Adjustments: Geometry 32 Name Description Present for digital signals? Automatic Geometry This is the same function as in the Autosetup menu. Please refer to the description of the Autosetup functions above. After Automatic Geometry, the image is centered inside the active video window. Its size depends on the video resolution and the Scaling setting. No Scale settings Select the desired scaling option. None: The image is not scaled. Best Fit: The image is scaled proportionally (keeping the original aspect ratio) to obtain the largest possible image. Full: The image is scaled non-proportionally (the original aspect ratio may be lost) to fill the screen completely. Programmable: You can manually scale the image by defining a horizontal scale and a zoom factor. The zoom factor scales the image both horizontally and vertically. Yes Operation Adjustments: Phase This menu is not available for digital video signals. Name Description Automatic Phase This is the same function as in the Autosetup menu Frequency Adjust the video sampling frequency. This is necessary when you notice abnormal vertical banding, which can be seen best on a dot on/dot off pattern. The figure in the OSD is the total number of pixels per line (active + blanking). Man Phase adj Adjust the video sampling phase manually. However, we recommend you use the Automatic Phase function. 33 Operation Input Selection Name Description Automatic Automatically selects the input to which a video signal is connected. If more than one video signal is connected, priority is given to DVI. DVI_I Selects the DVI(-I) input. If both analog and digital video signals are connected, the digital signal has priority. DVI_D Manually select the digital signal on the DVI input. DVI_A Manually select the analog signal on the DVI input. VGA Manually select the DB15 (VGA) input. BNC Manually select the BNC input. The BNC input is for monochrome video only. Name Description DPMS Switch on/off the automatic power saving system (DPMS) Power LED Switch the power LED on/off. Note: The LED's orange DPMS state is not influenced by this setting. So, when the display goes into power-saving mode, the LED will turn orange, even if it was switched off by this setting. Ambient Light Compensation Switch on/off the Ambient Light Compensation (ALC) system. When switched on, ALC adjusts the display luminance constantly, based on the ambient light around the display.

Improper use of these functions may cause the display to not function correctly. Barco cannot be held responsible for the results or damage caused by improper use of these functions. About the Advanced functions The advanced functions are extensions of the standard OSD. By default, a user browsing through the OSD sees only the standard functions. When logged in in advanced mode, the user sees the standard and advanced functions in the OSD menus. To log in as advanced user: 1. Enter the main menu. 2. Rotate the control wheel to select the menu item EXIT. 3. Press and hold the control wheel for a few seconds until the OSD main menu is refreshed on the screen. You have now logged in as advanced user. This is indicated in the main menu heading. 37 Operation Advanced functions in the Adjustments menu Low Pass Filter This function is not available for digital video signals. The display electronics provide 4 different low-pass filter settings to filter possible high-frequent distortion from an analog video signal. Select a different filter setting in case the image contains high-frequent noise or distortion. Select the filter setting that gives the best result. Readjustment of sample phase is necessary after selection of a different filter. Geometry: Active Input Region When a video signal is connected, the display looks for a matching format in its VESA table. The VESA table contains the starting position (first line of the frames and first pixel of the lines) of the active video and the length of the active video (number of lines per frame and number of pixels per line). When there is no match with one of the formats in the table, the nearest format is chosen, possibly resulting in a not-perfectly aligned image. The user can align the image using the Automatic Geometry function. However, in some cases the user is not satisfied with the image after Automatic Geometry, or the video signal itself does not meet the requirements for a successful Automatic Geometry. In that case the user can manually define the active video region to display, creating offsets to the settings chosen by the display. In order to use these adjustments successfully, the scaling setting is preferably be set to None. The following offset adjustments are available: 38 Operation Name Description Left offset This function allows you to make an offset to the start (left) position of the active video. As you adjust this value, another pixel will be chosen as starting pixel. The active line width is not changed by this adjustment. As a visual result, the image moves horizontally. Right offset This function allows you to make an offset to the end (right) position of the active video. As you adjust this value, another pixel will be chosen as last pixel per line. This adjustment alters the active line width. Remark that the active video is always centered on the screen while this adjustment is made. Top offset This function allows you to make an offset to the start (top) line of the active video. As you adjust this value, another line will be chosen as first line. Bottom offset This function allows you to make an offset to the end (bottom) line of the active video. As you adjust this value, another line will be chosen as last line. Note: If you execute an Automatic Geometry function after these adjustments, all manual offsets will be erased. 39 Operation Ambient Light Compensation Name Description Min ALC Contains two functions to set the minimum point of the ALC control system: Min Ambient Light: Enter the value (in Lux) of the darkest possible ambient light condition you are likely to work in. Min Luminance: Enter the value (in %) that corresponds to the display luminance you wish to get when the ambient light is at the level you have entered for Min Ambient Light. Max ALC Contains two functions to set the maximum point of the ALC control system: Max Ambient Light: Enter the value (in Lux) of the brightest possible ambient light condition you are likely to work in. Max Luminance: Enter the value (in %) that corresponds to the display luminance you wish to get when the ambient light is at the level you have entered for Max Ambient Light. Gamma CRT If the selected Display Function (in the advanced Settings menu) is Gamma CRT, you can manually set the gamma value from 1 to 3. E.g., if you want the display function to be like a CRT gamma of 2.2, proceed as follows: 1. In the advanced Settings menu, select Gamma CRT as Display Function. 2. In the advanced Adjustments menu, set the Gamma CRT value to 2.2. 40 Operation Advanced functions in the Input Selection menu Generator This function displays an internally generated test pattern of 1280x1024 @ 57 Hz. Advanced functions in the Settings menu Input Mode To change the Input Mode setting, press the control wheel. Rotate the wheel to select Standard or Extended input mode. Then press the wheel again to enter the selected submenu. The following input mode settings can be selected: 41 Operation Name Description RGB->RGB The R video signal drives the R sub-pixels, the G video signal drives the G subpixels and the B video signal drives the B sub-pixels. This is the preferred setting for color display controllers. RGB->Y The RGB video signals from the imaging board are calculated and transformed into a single luminance value according to the formula 0.3R + 0.59G + 0.11B. This single luminance signal drives the RGB sub-pixels of the panel equally. Use this setting in case the imaging board is a color board and if the signal must be displayed in monochrome. R->Y The Red video signal from the imaging board is used as luminance value to drive the RGB subpixels of the panel equally. G->Y The Green video signal from the imaging board is used as luminance value to drive the RGB subpixels of the panel equally. B->Y The Blue video signal from the imaging board is used as luminance value to drive the RGB subpixels of the panel equally. User Controls When you disable this setting and exit the OSD, some functions of the control wheel are disabled. Please refer to the chapter about locking and unlocking user controls, to know how to use this function. 42 Operation OSD position With the OSD function you can select where on the screen the OSD menu text will appear.

Be careful with rings or other jewelry that can touch the LCD. • Do not apply pressure on the LCD panel. • Do not apply or spray liquid directly to the panel or cabinet as excess liquid may cause damage to internal electronics. Instead, apply the liquid to the cleaning cloth. LCD Proceed as follows: Clean the LCD using a sponge, cleaning cloth or soft tissue, lightly moistened with one of the following tested products: • Flux • Windex Glass Plus • Bohle glass cleaner • Mr. Proper • Pril • Ajax glass cleaner • Sidolin glass cleaner In case none of the above cleaning products is available, use plain water. Do NOT use: • Alcohol/solvents at higher concentration > 5% • Strong alkalis lye, strong solvents • Acid • Detergents with fluoride 47 Cleaning instructions • Detergents with ammonia • Detergents with abrasives • Steel wool • Sponge with abrasives • Steel blades • Cloth with steel thread Cabinet Proceed as follows: • Clean the cabinet using a soft cotton cloth, lightly moistened with a recognized cleaning product for medical equipment. • Repeat with water only. • Wipe dry with a dry cloth. • The cabinet has been tested for resistance to the following products: • Cidex, Betadine • Alcohol (Isopropyl and Ethyl) • Ammonia-based cleaners (Windex) • Aquasonic Gel 48 Troubleshooting Troubleshooting General tips • If one display from a multi-head system exhibits problems, try to eliminate the problem by switching video cables or power supplies. In that way you can find out if the problem resides in the display or not. Problems and solutions Problem description Possible tests or solutions Screen remains black • Please check the installation procedure in this manual • If the LED at the front is orange, the display is in stand-by • Check in the Windows Display Properties if the display controller video heads are attached. If not, there will be no image on the screen. • The external power supply may be defective • The video cable may be of poor quality • DVI video cable may not be firmly connected to the PC or to the display • Display may need Phase and Frequency adjustments (if analog video is selected) Image contains missing pixels • A number of missing pixels may be normal (inherent in LCD technology) The PC does not start up • Check the CMOS settings in the PC BIOS • The display controller may not be firmly seated in the PCI connector Image exhibits noise or interference 49 Troubleshooting Problem description Possible tests or solutions Nothing happens when you press or rotate the control wheel • The User Controls may be disabled. Please read the paragraph about the “User Controls” function. The image is non-proportionally spread out over the screen • Select another resolution in the Windows “Display Properties” control panel • Switch the “Scaling” function (Geometry menu) in the display OSD to “None” or “Best Fit” The image on the screen is rotated 90° • Select another resolution in the Windows “Display Properties” control panel The previous image remains slightly visible on the screen • This phenomenon, called “image sticking” is normal if the same image has been on the screen for a long time. The ghost image will disappear after some time. Over 10 hours operation with the same image content is not recommended. Switching on the display DPMS may decrease the risk of image sticking. • A slight case of image sticking can be solved by continuously displaying a full white image during a number of hours. • Switch the video cables at the display controller or at the display video inputs On a dual-head system, the images on the left and right display seem to be switched 50 Technical Information Technical Information Technical specifications MVGD 1319: Item Specification Picture panel 19-inch diagonal viewable screen TFT (thin film transistor) active matrix, grayscale liquid crystal display Resolution Native: 1280 x 1024 Display area (H x V) 376.3 x 301.1 (mm) Viewing angle (@ 10/1 contrast) Vertical: 170º Horizontal: 170º Pixel Pitch 0.294 mm (H) x 0.294 mm (V) Native color resolution 8 bits / sub-pixel Luminance 400 cd/m² (calibrated) Contrast ratio 1000/1 (on/off in dark environment) Response time 20 ms typical (@ 25° C after 30 min warmup) Controls Push / turn control wheel for stand-by switching and OSD controls Input connectors DVI, D-Sub15 pin, BNC Signal systems DVI Digital, RGB Analog Video on DVI: Complying to DVI Rev 1.0 specifications Sync on DVI: Complying to DVI Rev 1.0 specifications Power source 90 ~ 264 VAC 51 Technical Information Item 52 Specification Power consumption 64 watts (max., at 90 VAC, maximum backlight, USB load) Dimensions (W x H x D) 432 x 362.2 x 107 mm Net weight 8.1 kg Operating Temperature 0°C to 40°C, 15°C to 35°C within specs Storage Temperature -20°C to 60°C Humidity 8% - 80% (non-condensing) for operation 5% - 95% (non-condensing) for storage Altitude 7500 m storage 3000 m operation Technical Information Connector pin assignments DVI connector: 1 16 C1 C2 8 C5 9 17 C3 C4 24 Figure 10: DVI-I connector pin layout Pin no.

After this calibration, black and white luminance are set to the ideal level. A stabilization routine, constantly active when the display is on, keeps these levels constant using the built-in sensor. 54 Technical Information Display Function A Display Function describes how a display device converts the video signals at the inputs into light. In the context of a medical viewing station, a display device is the combination of display controller (graphics board) and display. The display function is a graph that shows how the light from the display panel evolves from minimum to maximum luminance while the data levels at the input of the display controller go from 0 to maximum. DICOM DICOM stands for Digital Imaging and Communications in Medicine. It is a standard developed by the American College of Radiology (ACR) and the National Electrical Manufacturers Association (NEMA). The standard specifies how digital image data can be moved from system to system. In addition, Supplement 28 Part 14 specifies a function that relates pixel values to displayed Luminance levels and is called Grayscale Standard Display Function. Presets and Internal memory system The memory of the display contains minimum 70 fixed and 59 programmable Presets. When you connect a video signal, the display checks in the memory for a matching Preset. If it finds one, it selects the corresponding settings and parameters from the memory. If it does not find a matching Preset, the display uses default settings to display the image. When you make adjustments and save the changes, the current Preset is saved as programmable Preset. If this happens while all programmable Presets are occupied, the oldest programmable Preset is overwritten automatically. 55 Warranty Statement Warranty Statement BARCO MID GENERAL WARRANTY TERMS AND CONDITIONS Applicable from Jan 1st 2008 ARTICLE 1: PRODUCT WARRANTY Barco nv, Medical Imaging Division warrants that the equipment will be free of defects in workmanship or material for the warranty period or the specific period of a warranty extension program.
