monitors, LCD monitors’ image persistence is not permanent, but a still image being displayed for a long period of time should be avoided. To alleviate image persistence, turn off the monitor for as long as the previous image was displayed. For example, if an image was on the monitor for one hour and a residual image remains, the monitor should be turned off for one hour to erase the image. �ROTEG: As with all personal display devices, we recommend using a moving screen saver at regular intervals whenever the screen is idle, or turn off the monitor when not in use.

REDUCE EYE, SHOULDER, AND NECK FATIGUE. CHECK THE FOLLOWING WHEN YOU POSITION THE MONITOR: To realize the maximum ergonomics benefits, we recommend the following: • For optimum performance of the monitor, allow 20 minutes for warming up. Avoid reproduction of still patterns on the monitor for long periods of time to avoid image persistence (after image effects). • Adjust the monitor height so that the top of the screen is at or slightly below eye level. Your eyes should look slightly downward when viewing the middle of the screen. • Position your monitor no closer than 40 cm (15.75 inches) and no further away than 70 cm (27.56 inches) from your eyes. The optimal distance is 50 cm (19.69 inches). • Rest your eyes periodically for 5 to 10 minutes for every 1 hour by focusing on an object at least 20 feet away. • Position the monitor at a 90° angle to windows and other light sources to minimize glare and reflections. Adjust the monitor tilt so that ceiling lights do not reflect on your screen. • If reflected light makes it hard for you to see your screen, use an anti-glare filter. • Adjust the monitor’s brightness and contrast controls to enhance readability. • Use a document holder placed close to the screen. • Position whatever you are looking at most of the time (the screen or reference material) directly in front of you to minimize turning your head while you are typing. • Blink often. Eye exercise helps to reduce eye strain. Please contact your ophthalmologist. Get regular eye checkups. • To avoid eye fatigue, adjust the brightness to a moderate setting. Place a sheet of white paper next to the LCD screen for luminance reference. • Do not position the Contrast control to its maximum setting. • Use the preset Size and Position controls with standard signals. • Use the preset Color Setting. • Use non-interlaced signals. • Do not use primary color blue on a dark background, as it is difficult to see and may produce eye fatigue due to insufficient contrast.

P.O. Box 1369, Santa Monica, California 90406. Cleaning the LCD Screen • When the LCD Screen is dusty, please gently wipe with a soft cloth. • Clean the LCD screen surface with a lint-free, non-abrasive cloth. Avoid using any cleaning solution or glass cleaner! • Please do not rub the LCD Screen with hard or coarse material. • Please do not apply pressure to the LCD Screen surface. • Please do not use OA cleaner as it will cause deterioration or discoloration on the LCD Screen surface. Cleaning the Cabinet • Unplug the power supply. • Gently wipe the cabinet with a soft cloth. • To clean the cabinet, dampen the cloth with a neutral detergent and water, wipe the cabinet and follow with a dry cloth. �ROTEG: DO NOT clean with benzene thinner, alkaline detergent, alcoholic system detergent, glass cleaner, wax, polish cleaner, soap powder, or insecticide. Rubber or vinyl should not be in contact with the cabinet for an extended period of time. These types of fluids and materials can cause the paint to deteriorate, crack or peel.

Connect the DisplayPort cable and make sure the picture image. The image is not properly reproduced • Use the OSD Image Adjust controls ([H POSITION], [V POSITION], [CLOCK], and [PHASE]). (Analog input only). • Use the [AUTO ADJUST] functions. (Analog input only). Picture is not bright • Make sure [ECO MODE] is [OFF]. • Make sure the signal cable is fully connected to the monitor and the computer. • LCD brightness degradation occurs due to long-term usage or extreme cold conditions. • If the brightness fluctuates, make sure [DV MODE] is set to [OFF]. Selected resolution is not displayed properly • If the resolution you set is over or under a range, “OUT OF RANGE” window will appear then warn you. Please set supported resolution at the connected computer. Brightness variations over time • Change [DV MODE] to [OFF] and adjust brightness. �ROTEG When [DV MODE] is set to [ON], the monitor automatically adjusts brightness based on the video signal. Ro Video • If no video is present on the screen, turn the button off and on again. • Make sure the computer is not in a power-saving mode by touching the connected keyboard or the connected mouse.

• Unplug the power cord of the monitor from the AC outlet to turn off and reset the monitor. Message “OUT OF RARNE” is displayed (screen is either blank or shows rough images only) • Image is displayed roughly (pixels are missing) and an OSD warning “OUT OF RANGE” is displayed: Either signal clock or resolution is too high. Choose one of the supported modes. • An OSD warning “OUT OF RANGE” is displayed on a blank screen: Signal frequency is out of range. Choose one of the supported modes. LED on monitor is not lit • Make sure the power cord is properly connected to the monitor and the wall, and make sure the monitor’s power switch is on. • Set [POWER INDICATOR] is [ON]. Ro Sound • Check to see if the speaker cable is properly connected. • Check to see if [MUTE] is activated. • Check to see if [VOLUME] is set to a minimum. • Check to see if the computer supports an audio signal through DisplayPort or HDMI. • Check selected [SOUND INPUT] when DisplayPort or HDMI is in use. Image Persistence Please be aware that LCD Technology may experience a phenomenon known as Image Persistence. Image Persistence occurs when a residual or “ghost” image of a previous image remains visible on the screen. Unlike CRT monitors, the image persistence on LCD monitors is not permanent, but single still image being displayed for a long period of time should be avoided. To alleviate image persistence, turn off the monitor for as long as the previous image was displayed. For example, if an image was on the monitor for one hour and a residual image remains, the monitor should be turned off for one hour to erase the image. �ROTEG: As with all personal display devices, we recommend using a moving screen saver at regular intervals whenever the screen is idle, or turning off the monitor when not in use.

ECO MODE Decreases the amount of power consumption by reducing the brightness level. OFF Sets the brightness variable range from 0% to 100%. 1 Sets the brightness variable range from 0% to 80%. 2 Sets the brightness variable range from 0% to 40%. CONTRAST Adjusts the image brightness in relation to the background. �ROTEG This function is disabled when [COLOR] is set to [L/B]. DV MODE (Dynamic Visual Mode) Adjusts the brightness by detecting the screen’s black areas and optimizes it. �ROTEG [OFF] is used for TCO Certificate compliance. This function is disabled when [COLOR] is set to [L/B]. COLOR Select the desired color setting from six color presets (9300 / 7500 / sRGB / USER / NATIVE / L/B*). RED Increases or decreases [RED].
