resolution? or how do you connect them to the machine - cable or power
source?
I don't have experience with 2 LVDS - how do you connect them - curious?
LVDS is
Low Voltage Differential Signalling output (typically a laptop LCD panel).
Available properties:
BACKLIGHT - current backlight level (adjustable)
By adjusting the BACKLIGHT property, the brightness on the LVDS output can
be adjusted. In some cases, this property may be unavailable (for example
if your platform uses an external microcontroller to control the
backlight).
scaling mode - control LCD panel scaling mode
When the currently selected display mode differs from the native panel
resolution, various scaling options are available. These include
Center
Simply center the image on-screen without scaling. This is the only scaling
mode that guarantees a one-to-one correspondence between native and
displayed pixels, but some portions of the panel may be unused
(so-called "letterboxing").
Full aspect
Scale the image as much as possible while preserving aspect ratio. Pixels
may not be displayed one-to-one (there may be some blurriness). Some
portions of the panel may be unused if the aspect ratio of the selected
mode does not match that of the panel.
Full
Scale the image to the panel size without regard to aspect ratio. This is
the only mode which guarantees that every pixel of the panel will be used.
But the displayed image may be distorted by stretching either horizontally
or vertically, and pixels may not be displayed one-to-one (there may be
some blurriness).
The precise names of these options may differ depending on the kernel video
driver, (but the functionality should be similar). See the output of
xrandr --prop for a list of currently available scaling modes.
