Connecting a flat panel display
The 5266 video supports most standard
TFT
flat panels through BIOS Setup
configurations. The 5266 support
s
flat panel resolutions from 320 x 240 up to 1024 x
768. Note that 3.3V flat panels are supported through the connector, while 5V
panels require an alternate power source. See “5V flat panels” in this chapter for
information on connecting a 5V flat panel.
Note
The 5266 does not support LVDS flat panels. Also, EL panels, and some quarter
VGA panels are not supported. Call Technical Support for information.
BIOS Setup for flat panels
In the BIOS Setup Custom Configuration menu there are four fields that you must
set to match your flat panel. These fields are Video device mode, which sets the
resolution; Video data width, which sets the pixels per clock; and FP HSYNC
Polarity and FP VSYNC Polarity, which set the respective sync signals as active
high or active low. Refer to your flat panel documentation for the appropriate
settings for these fields.
Figure 10–2 shows a flat panel connected to the 5266. Table 10–2 shows the pinout
for the J501 flat panel connector.
Flat panels requiring bias voltage
Some flat panels require a bias voltage. To determine if your flat panel requires
bias voltage, refer to your flat panel documentation. If your flat panel requires a
bias voltage, refer to the manufacturer’s documentation for procedures on
supplying the proper bias voltage.
WARNING!
Since improper voltage levels can severely damage the flat panel,
make sure the bias voltage is correct before the flat panel is
connected to the 5266.
5V flat panels
The 41-pin VESA connector provides 3.3V to power flat panels through pins 39 and
40 (see table 10–2). If your flat panel requires 5V, you will have to do the following:
1.
Clip the wires on your cable that correspond to pins 39 and 40, so that 3.3V
does not feed through to your flat panel.
2.
Use the 3.3V from pin 39 or 40 as an input to a FET or a power supply control
to create a controlled 5V supply.
3.
Bring your 5V into the FET or power supply control, and use the controlled 5V
output to power your flat panel.
