Recommend maintaining aspect ratio of source and following usage
guidelines regarding window/button placement.
Network congestion can cause video glitches. AMX recommends the
Multi-Preview Live and Modero X touch panel be installed behind a smart
Ethernet switch to filter multicast packets reaching the panel and
consuming panel resources.
The MXA-UENET video accelerator cable (
FG5968-74/75/76
) may also
improve performance in cases of network congestion.

The MXA-UENET video accelerator cable (

) is strongly
recommended for this application.
Network congestion can cause video glitches. AMX recommends the
Modero X touch panel be installed behind a smart Ethernet switch to
filter unintended multicast packets reaching the panel and consuming
panel resources.
Recommend maintaining aspect ratio of source and following usage
guidelines regarding window/button placement.
• AAC <= 192Kbps @ 48KHz
• H.264 video 720p max (D1 for best results),< 30fps max and a 4Mbps
bitrate
• UDP Transport protocol only (RTP not supported)
• Multicast and/or unicast addresses
• SAP disabled
May require transcoding to H.264 baseline profile and reducing
resolution/ frame rate/bit rate per recommendations above.
Recommend transcoding source material to MPEG2 if Audio/Video sync
issues still occur after following above guidelines.

The MXA-UENET video accelerator cable (
FG5968-74/75/76
) is
recommended for this application, especially HD streams.
Network congestion can cause video glitches. We recommend the panel
be installed behind a smart Ethernet switch to filter unintended multicast
packets reaching the panel and consuming panel resources.
Recommend maintaining aspect ratio of source and following usage
guidelines regarding window/button placement. Best results are
obtained with standard definition (NTSC or PAL) sources.
Minor audio/video irregularities may be noticed depending on network
performance, video source content, and window size. Note: Video frame
rate can be affected by network performance.
MPEG-2 video streaming Settings:
• MP2/MP3 audio <= 192Kbps @ 48KHz
• MPEG2 video 720p max < 30fps max bitrate of 8Mbps
• UDP Transport protocol only (RTP not supported)
• Multicast and/or unicast addresses
• SAP disabled
