10.1 Graphics Interface
10.1.1 DVI ® Monitor
The Android TM graphic driver does not offer full EDID support. In most cases two supported resolutions
(SXGA and Full-HD) are enough. You need to add the entry ' persist.tegra.hdmi.resolution ' in the system file
' build.prop ', detectable in the directory /system . The driver accepts following values:
Vga, 480p, 576p, 720p, SXGA and 1080p
Example for Full-HD:
persist.tegra.hdmi.resolution=1080p
10.1.2 LCD Panel
There are no restrictions regarding the supported resolutions. With DisplayID all panels with single channel
can be attached.
10.2 Video Decoding
The integrated video player in the operating system allows hardware accelerated video decoding but this
player offers only some video formats. Another good choice represents the MX Video Player.
The following table gives an overview about the limitations:
Video Format Profile / Level Max. Resolution / Frame Rate Max. Throughput Comment
DivX 4/5/6 1080p HD 1920 x 1080 / 30 fps 10 Mbps
Xvid Highdef 1920 x 1080 / 30 fps 10 Mbps
MPEG-4 Advanced Simple / L4 1920 x 1080 / 30 fps 10 Mbps
H.264 Baseline (BP) / L4 1920 x 1080 / 30 fps 10 Mbps
H.264 Main (MP) / L3.1 1280 x 720 / 30 fps 4 Mbps CAVLC
H.264 Main (MP) / L3.1 1280 x 720 / 30 fps 4 Mbps CABAC, CAVLC
H.264 High (HiP) / L3.1 1280 x 720 / 30 fps 4 Mbps CAVLC
H.264 High (HiP) / L3.1 1280 x 720 / 30 fps 4 Mbps CABAC, CAVLC
Please note that the maximal throughput data are peak values not average values. You may need to re-
encode your videos with parameters above to get smooth video output.
ATTENTION
The VC1 video codec is not supported
