> It seems that you still use the DVI to connector the monitor.
This is correct. I use VGA only if requested.

> How about using VGA?
Result is very similar compared to DVI:

- With VGA, mode 0x4a puts the monitor to standby mode which can usually be undo be switching back the previous mode (0x49 in my test). Mode 0x4d causes the "flickering white screen". Sometimes the white screen is about half a second and then it works. But when I switch the second time to this mode the error stays and I can not switch to a working mode again.

- With DVI I have the same results but with mode 0x49 and 0x4c instead of 0x4a and 0x4b.
