why cant I set a higher resolution.  even the intel gma software says the correct display mode but wont let me set it.
I have read other posts where DTDs needed to be changed.  I can do that just dont know what settings to use.

Thanks in advance for helping .

Try

BA 1D 56 15 51 00 04 30 40 4011 00 00 00 00 00 00 18

Also possible: VAIO BIOS may be prohibiting 1366x768. Try 1364x768:

BA 1D 54 17 51 00 04 30 40 4011 00 00 00 00 00 00 18

The third possibility is the persistence bug which has been seen on many systems since driver release 14.33.
