This chapter provides information for solving problems that may occur when using your flat panel monitor. For further troubleshooting information, see the manual that came with your flat panel monitor's adapter board for your computer.
The LED on the left bottom side of the flat panel monitor indicates the state of the monitor. Table 2-1 explains the LED states and offers possible solutions if a problem occurs.
Table 2-1. Explanation of LED States
LED | State | Monitor State | Possible Causes and Solutions |
|---|---|---|---|
LED is Off | 0 | Screen | Power button is off. Power cable is not connected. Interface cable is not connected to the computer. |
Blinking yellow | 1 | Screen | Software is not configured correctly. See the manual that came with the monitor's adapter board for your computer. An interface cable is loose or disconnected. The adapter board (in systems so equipped) is loose or otherwise not installed properly. |
Solid green | 2 | Screen and
backlighting | The flat panel is operating normally. |
Solid yellow | 3 | System | System Power Save mode has turned off the screen because there has been no keyboard or mouse action for a while. Move the mouse or touch the keyboard to enable the monitor. |
Subsequent sections offer more detailed troubleshooting information. In addition, check any documents that came with your monitor's adapter board.
If the problem persists after following the suggestions below, call your service provider.
Check to see if the flat panel monitor and computer are turned on. (Press the power button on the front of the monitor.) The flat panel monitor takes about a minute to warm up to full brightness.
Check the color of the LED on the front of the flat panel monitor and look for a possible cause in Table 2-1.
Make sure that the DC power cable is connected securely to the flat panel monitor.
Check that the correct AC power cable for your country (110 V or 220 V) is connected securely to the AC adapter and to a working wall outlet or power strip. (See “Connecting the Cables”.)
Check that the interface cable is connected securely to the flat panel monitor's adapter's connector on the computer. (See “Connecting the Cables”.)
If you recently installed the flat panel monitor's adapter board in your computer, the board may not be installed correctly, or the software may not be installed. Follow the instructions in the installation manual that came with the board to make sure you installed the hardware and software correctly. Also, you can reseat the adapter board in the computer to make sure that the board is making proper electrical contact.
If the flat panel monitor was not connected to the computer via the interface cable when the computer was turned on, reboot the computer so that the correct timing table is used for the flat panel monitor.
The images on flat panel monitors look lighter or darker when viewed from different angles (especially from highly oblique angles). Check that your line of sight is as close to perpendicular as possible. See “Recommended Use and Viewing Angles” on page 11 and Table 3-1.
Considerable development has been done to ensure that your flat panel monitor has the widest possible viewing angles without compromising such features as displaying fast-moving video. For more technical information, see “Technical Specifications” on page 26.
It takes about one minute for flat panel monitors to warm up to full brightness from a cold start, so at first the image may appear dim or faded. This is because the ambient air temperature affects the startup brightness of the flat panel monitor. For example, when the air temperature is about 77 °F (25 °C), the panel is initially at about 80% of its maximum brightness. However, at 50 °F (10 °C), the light output can start with as little as 30% of its maximum brightness.
Eventually, as the backlight lamps warm up, the monitor should reach its maximum brightness, as long as it is being operated within the proper temperature range. See Table 3-4 for the operating temperature range.
Occasionally you may notice some bright dots on the monitor that remain in the same place regardless of the image being displayed on the screen. This is intrinsic to thin-film transistor (TFT) liquid crystal displays (LCDs) and does not indicate a defective screen.
A wealth of information is available through SupportFolio, the SGI online technical support tool available at http://support.sgi.com/nt. SupportFolio lets you browse frequently asked questions, search for technical information, and download SGI's latest software updates.

If your service provider instructs you to return the flat panel monitor, follow the instructions below.
| Note: If you are instructed to return the adapter board for your flat panel monitor, check the documentation that came with the adapter board for removal and return instructions. |
Turn off your computer. Disconnect the power cable from the rear of the flat panel monitor.
Disconnect the interface cable from your computer.
Replace the original protective plastic film over the monitor's screen. Be sure the plastic film is clean and free of grit that may damage the monitor's screen.
If your service provider instructs you to do so, remove the flat panel monitor from its base. See “Removing the Flat Panel Monitor From Its Base” and “Replacing the Flat Panel Monitor On Its Base”.
If you receive a replacement flat panel monitor, use that shipping carton and packing materials to return the faulty monitor, or use the flat panel monitor's original shipping carton and packing materials.
