Cisco Cisco Digital Media Player 4300G Guida All'Installazione

When image signals are transmitted through a composite cable, image quality suffers. When you use a composite cable 
and your DMP shows any web-based media, small text might be difficult to read in TVzilla. To work around this limitation, you can 
lower the browser resolution setting in DMPDM.

With most modern, digital presentation systems, an HDMI cable connection can carry video and audio 
signals together. 

Other such systems might not connect until you combine the HDMI cable with an HDMI-to-DVI adapter 
for video. However, DVI does not support the transmission of audio signals. In this case, you can use the 
provided audio cable for audio. 

A manufacturing error in your third-party presentation system might cause your DMP to render visual 
assets at an unexpectedly low-resolution for playback. This can occur when all of the following 
statements are true for you simultaneously.

Your DMP model is 4310G.

Your presentation system’s media signal interface is DVI, not HDMI.

EDID data in the firmware for your presentation system misrepresents its native resolution.

The falsely claimed resolution is an HDMI standard instead of a VESA standard.

In this case, your DMP 4310G proceeds as if the native resolution is low, to ensure that your digital sign 
shows anything at all. 

This constraint does not affect a DMP 4305G or a DMP 4400G. These models do not use the same microprocessor that a 
DMP 4310G uses.

To work around this behavior, disable the autodetect feature in DMPDM and then choose the actual 
resolution manually.
