computer’s graphics board in the following ranges.
Horizontal frequency: 28 – 61 kHz (SDM-X52) 28 – 92 kHz (SDM-X72/X82)
Vertical frequency: 56 – 75 Hz (SDM-X52) 56 – 85 Hz (SDM-X72/X82)

If using Windows,

• If you replaced an old monitor with this monitor, reconnect the old monitor and do the

following. Select “SONY” from the “Manufacturers” list and select “SDM-X52” or “SDM-
X72” or “SDM-X82” from the “Models” list in the Windows device selection screen. If “SDM-
X52” or “SDM-X72” or “SDM-X82” does not appear in the “Models” list, try “Plug & Play”
or install the information file for this monitor using the Windows Monitor Information Disk.

If using a Macintosh system,

• When connecting a Macintosh computer, use an adapter (not supplied) if necessary.

Connect the adapter to the computer before connecting the video signal cable.

Picture flickers, bounces,

• Isolate and eliminate any potential sources of electric or magnetic fields such as other

monitors, laser printers, electric fans, fluorescent lighting, or televisions.

• Move the monitor away from power lines or place a magnetic shield near the monitor.
• Try plugging the monitor into a different AC outlet, preferably on a different circuit.

Problem caused by a connected computer or other equipment, and not

caused by the monitor

• Check your graphics board manual for the proper monitor setting.
• Confirm that the graphics mode (VESA, Macintosh 19'' Color, etc.) and the frequency of the input

signal are supported by this monitor. Even if the frequency is within the proper range, some graphics
boards may have a sync pulse that is too narrow for the monitor to sync correctly.

• This monitor does not process the interlace signals. Set for progressive signals.
• Adjust the computer’s refresh rate (vertical frequency) to obtain the best possible picture

(60 Hz is recommended).
