Notice for this monitor
Notice for this monitor
Aside from general purposes like creating documents, viewing multimedia content, this product is also suited to applications such as creations of images and
graphics, and digital photo processing, where accurate color reproduction is a priority.
This product has been adjusted specically for use in the region to which it was originally shipped. If the product is used outside the region, it may not operate as
specied in the specications.
This product may not be covered by warranty for uses other than those described in this manual.
The specications noted in this manual are only applicable when the following are used:
· Power cords provided with the product
· Signal cables specied by us
Only use optional products manufactured or specied by us with this product.
If you place this product on a lacquer-coated desk, the color may adhere to the bottom of the stand due to the composition of the rubber. Check the desk surface
before use.
It takes about 3 minutes (under our measurement conditions) for the performance of electrical parts to stabilize. Please wait 30 minutes or more after the monitor
power has been turned on, and then adjust the monitor.
Monitors should be set to a lower brightness to reduce changes in luminosity caused by long-term use and maintain a stable display.
When the screen image is changed after displaying the same image for extended periods of time, an afterimage may appear. Use the screen saver or power save
function to avoid displaying the same image for extended periods of time.
If the monitor displays continuously over a long period of time, dark smudges or burn-in may appear. To maximize the life of the monitor, we recommend the monitor
be turned o󰀨 periodically.
Periodic cleaning is recommended to keep the monitor looking new and to prolong its operation lifetime (refer to “Cleaning” (page 4)).
The LCD panel is manufactured using high-precision technology. Although, missing pixels or lit pixels may appear on the LCD panel, this is not a malfunction.
Percentage of e󰀨ective dots: 99.9994% or higher.

Notice for this monitor
The backlight of the LCD panel has a xed lifetime. When the screen becomes dark or begins to icker, please contact your local EIZO representative.
Do not press on the panel or edge of the frame strongly, as this may result in display malfunctions, such as interference patterns, etc. If pressure is continually
applied to the panel, it may deteriorate or damage your panel. (If the pressure marks remain on the panel, leave the monitor with a black or white screen. The
symptom may disappear.)
Do not scratch or press on the panel with any sharp objects, as this may result in damage to the panel. Do not attempt to brush with tissues as this may scratch the
panel.
When the monitor is cold and brought into a room or the room temperature goes up quickly, dew condensation may occur on the interior and exterior surfaces of the
monitor. In that case, do not turn the monitor on. Instead wait until the dew condensation disappears, otherwise it may cause some damage to the monitor.
Cleaning
Attention
• Chemicals such as alcohol and antiseptic solution may cause gloss variation, tarnishing, and fading of the cabinet or panel, and also quality deterioration of the image.
• Never use any thinner, benzene, wax, and abrasive cleaner, which may damage the cabinet or panel.
The stains on the cabinet and panel surface can be removed by using the provided ScreenCleaner.
To use the monitor comfortably
• An excessively dark or bright screen may a󰀨ect your eyes. Adjust the brightness of the monitor according to the environmental conditions.
• Staring at the monitor for a long time tires your eyes. Take a 10-minute rest every hour.

(Tilt: up 35˚/down 5˚, Swivel: 344˚, Adjustable height: 145 mm (Tilt: 35°), 155 mm (Tilt: 0°))
• This product is equipped with a built-in calibration sensor, and supports SelfCalibration in which the monitor executes calibration independently.
See “SelfCalibration” (page 24)
• Compatible with Color Management Software “ColorNavigator 7”, which enables you to calibrate monitor characteristics and generate color proles

- 8 -
Chapter 1 Introduction
• Equipped with a USB Hub function that supports USB 3.0
Achieves high-speed data transfers of up to 5 Gbps, which enables transfers of large amounts of data to and from USB-connected devices in a short amount time.
Also, the “CHARGE” USB downstream port supports quick charging, so you can recharge your smartphone or tablet in a short period of time.
See “6-5. Making Use of USB (Universal Serial Bus)” (page 47) and “USB CHARGE Port” (page 31)
• Monitor hood is included
Includes a monitor hood that can e󰀨ectively shield the monitor from the reection of external lighting, such as the reected glare of a uorescent light.
• Displays HDCP (High Bandwidth Digital Protection) protected contents.
Attention
Be careful of the following points when using the built-in calibration sensor.
Do not touch the built-in calibration sensor.
It may reduce the measurement accuracy of the built-in calibration sensor, or result in injury or equipment damage.
Attention
• A high temperature or high humidity environment may a󰀨ect the measurement accuracy of the built-in calibration sensor. We suggest storing and using the monitor under the
following conditions.
- Temperature 30 ºC or less
- Humidity 70% or less
Avoid storing or using the sensor where it may be exposed to direct sunlight.
• Since the measurement result for the built-in sensor may be a󰀨ected, ensure that the level of ambient light that enters the receiver part of the built-in sensor does not change
signicantly during measuring. Do not touch the screen while measurement is in progress.
- The use of the monitor hood is recommended.
- While measuring, do not bring your face or any objects close to the monitor, do not look into the sensor.
- Set the monitor in the environment so that external light does not enter the sensor directly.

Temperature Native
4000 K to 10000 K
Adobe®RGB
sRGB
The color temperature can be adjusted.
The color temperature is used to express the hue of “White” or
“Black” by a numerical value. The value is expressed in degrees “K”
(Kelvin).
The screen becomes reddish at a low color temperature, and blu-
ish at a high color temperature, like the ame temperature.
Specify color temperature in units of 100 K, or select a color
temperature that complies with each standard.
• When you select “Native”, the original color of
the monitor (Gain: 100% for each RGB) is dis-
played.
• “Gain” allows you to perform more advanced
adjustment. When gain is changed, the color
temperature is changed to “User”.
• The gain preset values are set for each color
temperature setting value.
Gamma 1.6 to 2.7
Adobe®RGB
sRGB
Adjust the gamma.
The brightness of the monitor varies depending on the input
signal, however, the variation rate is not simply proportional to the
input signal. The control performed to keep the balance between
the input signal and the brightness of the monitor is called “Gam-
ma correction”.
You can set the gamma, or select the gamma curve dened by
each standard.
-
Color Gamut Native
Adobe®RGB
sRGB
Set the color reproduction area (color gamut).
“Color gamut” is the range of colors that devices such as monitors,
digital cameras and printers can represent. Multiple standards are
dened.
• When you select “Native”, the original color
gamut of the monitor is displayed.
• The method of displaying colors outside the
monitor’s displayable range within the dened
color gamut can be set. For more information,
see “Clipping” (page 21).
Advanced Set-
tings
Hue -100 to 100 Adjust the hue. • Using this function may make some color
gradations unavailable for display.
Saturation -100 to 100 Adjust the color saturation. • Using this function may make some color
gradations unavailable for display.
• The minimum value (-100) changes the
screen to monochrome.
