Imaging Problems

The screen is too bright or too dark

• Adjust "Brightness" or "Contrast" in the Setting menu to adjust it (see Color). (The LCD monitor backlight has a limited life span. If the screen becomes dark or begins to flicker, contact your local EIZO representative. )
• If the screen is too bright, try changing the Auto EcoView setting to "On". The monitor detects the ambient brightness to adjust the screen brightness automatically (see Auto EcoView).

The brightness changes on its own

• Try changing the Auto EcoView setting to "Off" (see Auto EcoView).
• Try changing the EcoView Optimizer 2 setting to "Off" (see EcoView Optimizer 2).

Characters and images are blurred

• Try setting the magnification of display on the OS to "100 %". When using multiple monitors, try setting the magnification of display to "100 %" on all monitors.

Afterimages appear

• This is common with LCD panels. We recommend avoid using the monitor to display fixed images for extended periods of time.
• Use the screensaver or power save function on your computer if you are going to be displaying the same image for a long period of time.
• An afterimage may appear even after a short time period has elapsed depending on the displayed image. To remove such a phenomenon, change the image or keep the power turned off for several hours.
• Check if the signal is not being output as an interlaced signal.

Green / red / blue / white / dark dots remain on the screen

• This is due to LCD panel characteristics and not a malfunction.

Interference patterns or pressure marks remain on the LCD panel

• Leave the monitor with a white or black screen. The symptom may disappear.

Noise appears on the screen

• In the Setting menu, set "Overdrive" to "Off" (see Advanced Settings - Overdrive).
• When inputting HDCP system signals, normal images may not be displayed immediately.

The positions of windows and icons are shifted when the monitor is turned off/on or when restored from power saving mode

• Turn the setting "On" for "Compatibility Mode" on the "Administrator Settings" menu (see Compatibility Mode).

The color shown on the screen is not correct

• Try changing "Input Color Format" in the Setting menu (see Input Color Format).

Images are not displayed over the entire area of the screen

• Try changing "Picture Expansion" in the Setting menu (see Picture Expansion).
• Check whether the setting for the resolution of the PC matches the resolution of the monitor.

Other Problems

The Setting menu does not appear

• Check whether the operation switch lock function is active (see Key Lock).

Cannot select items in the Setting menu

• Items that are displayed with gray text cannot be changed.
• "Color" items cannot be changed in some color modes. Setting the color mode to "User 1" or "User 2" will allow you to change all items (see Color).

No audio output

• Check whether volume is set to 0.
• Check the PC and audio playback software to see whether they are configured correctly.
• If using PbyP display, check the audio setting in "PbyP Settings" (see Switching the Audio (PbyP Display)).
• If using PinP display, check the audio setting in "PinP Settings" (see Switching the Audio (PinP Display)).

USB peripheral devices connected to the monitor do not work / Cannot use the Docking Station Function

• Check whether the USB cable is correctly connected between the PC and the USB upstream port on the monitor.
• When multiple PCs are connected to one monitor, check whether the correct USB upstream port is enabled (see Share USB Devices Between Two PCs).
• Check whether the peripheral device is correctly connected to the USB downstream port on the monitor.
• Try using a different USB downstream port on the monitor.
• Try using a different USB port on the PC.
• Check whether the device drivers of the peripheral devices are up-to-date.
• Reboot the PC.
• When "Compatibility Mode" is set to "Off" in the "Administrator Settings" menu and the monitor power is turned off, devices connected to the USB downstream port are not operational. Set "Compatibility Mode" to "On" (see Compatibility Mode).
• In the following cases, the LAN port cannot be used.
• When "Administrator Settings" is set to "Ethernet" in the "Off" menu. Set "Ethernet" to "On" (see Ethernet).
• When a USB-C connection is not used.
• When the operating system of the PC is not supported (see Network).
• If the peripheral devices work correctly when they are directly connected to the PC, contact your local EIZO representative.
• Depending on the USB host controller you are using, the connected USB device may not be recognized properly. Update to the latest USB driver provided by the manufacturer, or connect the monitor to the USB 2.0 port.
• Check the PC's BIOS (UEFI) setting for USB when using Windows. (See the manual of the PC for details.)
• Check if the operating system of the PC is up-to-date.
• If you are using macOS Ventura (13) or later, select "Allow" in the "Allow accessory to connect?" message window that appears when connecting via USB.

Power indicator is flashing orange and white

• This issue may occur when the PC is connected to the DisplayPort connector. Use a signal cable recommended by us for the connection. Turn the monitor off and on.
• Check the connection and condition of the USB peripheral devices connected to the monitor.
• Check that the power required for the USB peripheral device connected to the monitor does not exceed the power that can be supplied from the USB port of the monitor.
• Turn off the main power switch on the back of the monitor, and then turn it on again.
• If the monitor is connected to a laptop with a USB-C cable, connect an AC adapter to the laptop.

Even when operating a mouse or keyboard connected to the USB downstream port of the monitor, the PC does not return from sleep

• Turn the setting "On" for "Compatibility Mode" on the "Administrator Settings" menu (see Compatibility Mode).

The monitor does not supply power (USB Power Delivery) to the PC

• Check whether the PC has the specifications to operate with a 94 W power supply.
• For a 94 W power supply, use the following USB cables:
• CC200SS-5A or CC200SSW-5A (Included)
• CC100 (Optional accessory)

The message "Changes to this setting may increase power consumption." appears on the screen

Example:

This is a message that will only be displayed during the initial setup when using a function that may potentially increase power consumption. Select "OK" to proceed to the next step.

Remote control operations are not possible

• Check if the batteries in the remote control are depleted.
• Check that the remote control receiver of the monitor is not hidden or dirty.
• Make sure that you are operating the remote control within the remote control reception range of the monitor.
