Menu Option	Description
Aspect Ratio	The Aspect Ratio is the ratio of the image width to the image height. Auto Scales an image proportionally to fit the projector’s native resolution in its horizontal width. This is suitable for the incoming image which is neither 4:3 nor 16:9 and you want to make the most use of the screen without altering the image’s aspect ratio. 4:3 Scales an image so that it is displayed in the center of the screen with a 4:3 aspect ratio. This is most suitable for 4:3 images like computer monitors, standard definition TV, and 4:3 aspect DVD movies, as it displays them without aspect alteration. 16:9 Scales an image so that it is displayed in the center of the screen with a 16:9 aspect ratio. This is most suitable for images which are already in a 16:9 aspect, like high definition TV. Native Default aspect ratio.
Brightness	The higher the value, the brighter the image. Lower values will result in a darker image.
Contrast	Use this to set the peak white level after you have previously adjusted the Brightness setting to suit your selected input and viewing environment.
Tint	The higher the value, the more greenish the picture becomes. The lower the value, the more reddish the picture becomes.
Saturation	Refers to the amount of that color in a video picture. Lower settings produce less saturated colors; in fact, a setting of “0” removes that color from the image entirely. If the saturation is too high, that color will be overpowering and unrealistic.
Sharpness	A high value results in a sharper picture; a low value softens the picture.
Gamma	Manually adjust the brightness level of the monitor’s grayscale levels.
Color Temp	Manually adjust the red, green, and blue values.
Reset	Return the Display Mode settings to their default values.

Using the Direct View LED Display Safely

Please read the following Safety Precautions before you start using the device.

Keep this user guide in a safe place for later reference. Read all warnings and follow all instructions. Ensure there is no direct airflow from air conditioning blowing on the display. Do not use the device near water. To reduce the risk of fire or electric shock, do not expose the device to moisture. Avoid exposing the device to direct sunlight or other sources of sustained heat. Do not install near any heat sources such as radiators, heat registers, stoves, or other devices (including amplifiers) that may increase the temperature of the device to dangerous levels. When moving the device, be careful not to drop or bump the device on anything. Do not place the device on an uneven or unstable surface. The device may fall over resulting in an injury or a malfunction. Do not place any heavy objects on the device or connection cables. If smoke, an abnormal noise, or a strange odor is present, immediately turn the device off and call your dealer or ViewSonic®. It is dangerous to continue using the device. Do not attempt to circumvent the safety provisions of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A grounding-type plug has two blades and a third grounding prong. The wide blade and the third prong are provided for your safety. If the plug does not fit into your outlet, obtain an adapter and do not attempt to force the plug into the outlet. When connecting to a power outlet, DO NOT remove the grounding prong. Please ensure grounding prongs are NEVER REMOVED.

Protect the power cord from being treaded upon or pinched, particularly at the plug, and at the point where it emerges from the equipment. Ensure that the power outlet is located near the equipment so that it is easily accessible. Only use attachments/accessories specified by the manufacturer. When a cart is used, use with caution when moving the cart/equipment combination to avoid injury from tipping over. Disconnect the power plug from the AC outlet if the device is not being used for a long period of time. Place the device in a well-ventilated area. Do not cover the surface of the display with any material. Do not block the air circulation around the display. Keep flammable materials away from the display. Refer all servicing to qualified service personnel. Service will be required when the unit has been damaged in any way, such as: if the power supply cord or plug is damaged; if liquid is spilled onto or objects fall in the unit; if the unit is exposed to moisture; if the unit does not operate normally or has been dropped. Do not assemble the display by yourself. This panel is an advanced product that contains millions of pixels. You may occasionally see pixel spots when viewing the screen. Since these deactivated pixels are not a defect, the performance and reliability of the product is not affected.

Maintaining the LED Display

General Precautions

• The LED lights used in the modules are susceptible to ESD (Electrostatic discharge). To prevent damage to the LED lights, do not touch them with bare hands or with conductive materials when handling.
• It is recommended to regularly inspect all installed components.
• Do not bring objects close to the ventilation holes of the display. Burns or personal injuries may occur if any body parts are brought too close.
• Be sure to power off and disconnect all cables before moving the display. Moving the display with its cables attached may damage the cables and thus cause fire or electric shock.
• Power off and disconnect the power plug from the wall outlet as a safety precaution before performing any type of cleaning or maintenance.

Initial Operation

• If a new screen has been stowed for less than three (3) months, it can be used at normal brightness during its first use.
• If a new screen has been stowed for more than three (3) months, the brightness should be set at 30% for its first use and allowed to operate for two (2) hours continuously. After two (2) hours of use, power off for 30 minutes. The new screen is now ready for normal brightness usage.

Front Panel Cleaning Instructions

• Use cool, compressed air to remove dust when the power is off. If the dust cannot be removed, the LED module should be replaced.
• Do not scratch and do not put pressure on the panel surface with fingers or any abrasive object.
• Do not use volatile substances such as sprays, solvents, or thinners.

Cabinet Cleaning Instructions

• Do not allow water or detergent to come into contact with the surface of the display. If water or moisture gets inside the unit, a system malfunction or electrical shock may occur.
• Do not scratch and do not put pressure on the cabinet with any abrasive objects of any kind.
• Do not use volatile substances such as sprays, solvents, or thinners on the cabinet.
• Do not place anything made from rubber or PVC near the cabinet for any extended periods of time.

Regular Use

• It is recommended to turn on the display at least once a month for more than eight (8) hours. During a wet and rainy season, it is recommended to turn on the display at least once a week.
• Avoid using full white, full red, full blue, or full green content for an extended period to avoid excessive power usage thus affecting the LED lifespan.
