Point to be checked and action to be taken
● Check if the display's power switch is turned on, if the
display's contrast or brightness control volume is
adjusted properly, or if the power cable is normally
connected to both display and outlet.
● Check if the display cable is normally connected to both
display and system unit. See Hitachi Compute Rack
210H Getting Started Guide.
● Check if precision equipment is installed around the
system unit.
● Check if the system unit or display positions changed
during its use. Geomagnetic effects or color shading
might occur on the display. Turn off the power once
and leave at least 30 minutes before restart.
● Check if the system unit is too close to the display.
Keep the system unit properly distant from the display
or increase the refresh rate setting.
● Any cause cannot be identified.
Contact the sale representative, or maintenance
personnel.
● Check if the refresh rate is set beyond the display's
specification.
● Return the settings on the system BIOS to factory
defaults. See Hitachi Compute Rack 210H/220H BIOS
Guide.
● Abnormal operation can be attributed to the other
company's product. Ask the product manufacturer.
