--- Comment #10 from Kevin Brace <kevinbrace at gmx.com> ---
Xavier, I made some improvements in supporting DVI of MSI Fuzzy CN700G
mainboard.
The reason the code never worked well is because,

1) VT1632A DVI transmitter's I2C bus is connected to GPIO pins
2) GPIO based I2C bus appears to suffer from communication issues
3) There are issues with older X Server's I2C bus handling

Try the latest version code (Version 0.6.175) which improves the issues,
although there are still some issues with standby resume.
