LVDS – CRT Switching
Problem:
915GM/GMS/GME and 910GML/GMLE LVDS interface may hang while switching
between LVDS and CRT outputs.
Implication: Once LVDS interface hangs a system reset is required.
Workaround: Fixed in VBIOS, Please refer to release notes for VBIOS version 1220 or Newer.

NOTES:
Table reflects Intel tested Vos specification limits and the Mobile Intel
915GM/GMS/GME & 910GML/GMLE specification for Vos values. Intel may make
changes to specifications, release dates and product descriptions from time to time.
Implication: LVDS Panels sensitive to Vos range may not detect transmitted LVDS data. Potential
visual anomalies on LVDS display panels may occur, although no visual anomalies
have been reported due to Vos levels in the above tested range.
Workaround: None
Status:
For the steppings affected, see the Summary Tables of Changes.
