Can't set HD (1080p) resolution on my lenovo n100 - Intel 945

Hi,

I have Lenovo 3000 N100 (T5500, 4GB), Moblie Intel 945 Express Chipset Family.

Both bios and display adapters driversupdated.

I've bought a new HD screen - BENQ E-2200HD.

I can't set 1920x1080. The max is 1680x1050.

I've understand that I need to change a little bit the inf file of Intel's setup,

but I have no idea how.

The very stange thing is that on my second laptop - Lenovo S10-2 - I can see clearly with 1920x1080!

here is what moninfo have to say about this monitor:

I've tried to change some bytes to 94 43 80 90 72 38 28 40 80 C8 35 00 DC 0C 11 00 00 1E but it didn;t work:

kit20477.inf

[NonEDIDMode_AddSwSettings]

HKR,, TotalDTDCount, %REG_DWORD%, 1 ; This shows number of DTDs to be used. ; 0-->Disable the feature.

;Following keys have 20 bytes (18 byte DTD + 2 Byte flags).

HKR,, DTD_1,%REG_BINARY%, 94,43,80,90,72,38,28,40,80,C8,35,00,DC,0C,11,00,00,1E,37,01 ;1920x1080@60...Interlaced

someone? please?
