Inf editing help needed to get native 1680x1050 resolution

Hi all,

I have a DC7700 running Intels Q965 and cannot get my Philips 200WS monitor to show the native1680x1050 res. I have the following MonInfo:

*************

Start Component
Name = "Machine"
Start Group
Name = "Monitor Information"
ID = 1
Class = "Moninfo|Monitor Information|1.0"
Start Attribute
Name = "Windows description"
ID = 1
Type = String(50)
Storage = Specific
Value = "Philips Monitor"
End Attribute
Start Attribute
Name = "Manufacturer description"
ID = 2
Type = String(30)
Storage = Specific
Value = "Philips 200WS"
End Attribute
Start Attribute
Name = "Manufacturer"
ID = 3
Type = String(30)
Storage = Specific
Value = "Philips"
End Attribute
Start Attribute
Name = "Plug and Play ID"
ID = 4

End Attribute
Start Attribute

Type = String(30)

Value = "470 x 300 mm (~23 in.)"
End Attribute
Start Attribute
Name = "Raw EDID"
ID = 8
Type = String(256)
Storage = Specific
Value = "00FFFFFFFFFFFF00410C50080101010113110103082F1E782E9345A3554A9827155054BFEF00B300A940950F950081C08140714F818021399030621A274068B03600DA281100001C000000FF0043553130373139303037333235000000FC005068696C697073203230305753000000FD00384C1E5D11700A203230305753000A"

Hi again - Just to let you all know that I managed to solve the issue myself. This is what I did. I copied over the Raw EDID and set it up like at http://isnwiki.jot.com/WikiHome/Articles/111111431. Found the DTD, copied it to the igxp32.inf file as the 5 option. Set the number of options from 0 to 5, saved over the old igxp32.inf file and ran the setup.
After the restart the resolution could be found. Much respect to Archibael and thanks...T

Great news, Thomas. I'll admit I shuddered when I saw the raw EDID in your first message, but you evidently did exactly what I would have done anyway, and did it well. :)

I now have a user who complains that the resolution makes the text too small... So I have tried to also add a 1440x900 resolution but it is not just changing the resolution in the igxp32.inf file.

HKR,, DTD_5,%REG_BINARY%, 21,39,90,30,62,1A,27,40,68,B0,36,00,DA,28,11,00,00,1C,37,01 ;1680x1050@60 works perfect

HKR,, DTD_1,%REG_BINARY%, 21,39,A0,30,52,84,27,30,68,B0,36,00,DA,28,11,00,00,1C,37,01 ;1440x900@60 does NOT work!!

Any ideas?!?

Yeah, you're sending it 77Hz refresh. The refresh is reverse of byte 0 and 1 divided by total horizontal * total vertical:

(3921h) / (5A0h + 230h) * (384h + 27h) = 77Hz

The driver probably thinks that refresh is too high for your monitor at that resolution, so it's not even coming up.

Try

97 29 A0 D0 51 8420 30 50 98 13 00 00 00 00 00 00 1C

Check the registry to make sure it "takes" and populate it manually if it doesn't.

Hi archibael, Thanks a million - that did the trick!
Best wishes, Thomas

Hi! It's my first time here in the site.

I see you figured out the solution for this resolution problem. The problem is that the link you added is broken. can you please post here the way you fixed the problem?

Thanks alot!
