10.1 Graphics Interface

10.1.1 DVI

Monitor

The Android

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

H.264 Baseline (BP) / L4 1920 x 1080 / 30 fps

10 Mbps

H.264 Main (MP) / L3.1 1280 x 720 / 30 fps

H.264 Main (MP) / L3.1 1280 x 720 / 30 fps
