well, if You are readyto continue theexperiments, try this strings:
[NonEDIDMode_AddSwSettings]
HKR,, TotalDTDCount, %REG_DWORD%, 5 ; 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%, 02,3A,80,18,71,38,2D,40,58,2C,45,00,13,2B,21,00,00,1E,37,01 ;1920x1080@60...Non-interlaced
HKR,, DTD_2, %REG_BINARY%, F3,39,80,18,71,38,2D,40,58,2C,45,00,13,2B,21,00,00,1E,37, 01 ;1920x1080@59.94...Non-interlaced
HKR,, DTD_3,%REG_BINARY%, 01,1D,00,72,51,D0,1E,20,6E,28,55,00,13,2B,21,00,00,1E,37, 01 ;1280x720@60....Non-interlaced
HKR,, DTD_4, %REG_BINARY%, FA,1C,00,72,51,D0,1E,20,6E,28,55,00,13,2B,21,00,00,1E,37,01 ;1280x720@50.94....Non-interlaced
HKR,, DTD_5,%REG_BINARY%, 00, 00, 00 ,00, 00, 00,00, 00, 00,00, 00, 00,00, 00, 00,00, 00, 00,00, 00 ;Fifth DTD
If 1920x1080 resolution will lost again, then interesting to see if 1280x720 widescreen entry appears in list.
Alsocould be thatDellblocked 1920x1980 resolution in the BIOS, for some reason (such oddity known about them).
Thenyou can try:
[NonEDIDMode_AddSwSettings]
HKR,, TotalDTDCount, %REG_DWORD%, 1 ; This shows number of DTDs to be used.
HKR,, DTD_1,%REG_BINARY%, 02,3A,7E,1A,71,38,2D,40,5A,2C,45,00,13,2B,21,00,00,1E,37,01 ;1918x1080@60...Non-interlaced
or:
[NonEDIDMode_AddSwSettings]
HKR,, TotalDTDCount, %REG_DWORD%, 1 ; This shows number of DTDs to be used.
HKR,, DTD_1,%REG_BINARY%, 02,3A,7E,1A,71,38,2D,40,58,2C,45,00,13,2A,21,00,00,1E,37,01 ;1918x1080@60...Non-interlaced
