3.3.2 DisplayID

Restrictions

Depending on the graphic controller not all features can be used. The following table shows the most im-
portant restrictions.

Restrictions for MOPSlcdLX

Panels with dual or quad clock not supported (2 or 4 Pixel per Clock)
Variable power sequencing not supported

DisplayID

is not a solution for every LCD. Many displays center the picture automatically using the DE-

signal. In general the picture is centered automatically in horizontal direction but some displays also cen-
ter the picture vertically using this signal. Only for displays that can be driven with a

fixed mode

timing a

displacement of the picture is possible. For these information please check the datasheet. With the
MOPSlcdLX board the parameters for the typical detailled timing out of the datasheet might not be correct
for centering the picture. In general the exact positioning of the picture has to be obtained experimental.

3.3.3

LCD Panel Selection

The choice of an LCD display is basically defined by two parameters.

Parameter

Value

Pixel per Clock (Channels)

Maximum Pixel Clock

135 MHz

Currently this leads to a maximum resolution of

1024 Pixel

With the AMD graphic driver it is not guaranteed that every resolution can be achieved. KONTRON does not
guarantee the correct function of the board for untypical resolution. In principal the use of DisplayID

allows realizing every special display resolution. For this a valid DisplayID

dataset must be written to the

onboard EEPROM. Additionally the BIOS Setup entry

Advanced Chipset Features/LCD Resolution

must be set to

Auto.
