Try the IEGD drivers as per

Thats what I already did. I can choose moren resolution, but not the one i want to. 1920x1200 (16:10, but too high res) and 1280x800 (16:10, low) are available, but 1680x1050 is missing:(

Can you get the EDID information out of the display using MonInfo? I can see how to probably get you 1680x1050, but it's damned complicated. Not having the right EDID parameters would make it nightmarish.

Hi guys, I have the same problem :( I would like to buy new LCD but resolution 1680x1050 is missing in configuration, I hope you can help us. Thanks REALLY a lot !!!

Here are my EDID info.:

Raw EDID base
00: 00 FF FF FF FF FF FF 00 06 AF 01 0C 01 01 01 01
10: 01 0E 01 03 80 FF FF FF EA 00 00 A0 57 49 9B 26

70: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 03

(it's from MonInfo with a internal monitor /i don't know if there is any difference)

I tried to do that myself (http://softwarecommunity.intel.com/Wiki/Graphics/239.htm) but I don't have this "HKR,, TotalDTDCount, %REG_DWORD%, 0" in the .inf file. (I've got laptop DELL Inspiron 700m - it has 855GM chipset).

[Aaron_B_Intel]

Actually, we need the EDID from the monitor in question, not from the "internal monitor". That one's 1280x800, which I don't think is what we're looking for.

The 855 appears to have a different structure for which registry entries to modify, so the "TotalDTDs" won't work.

Ok, I'm sorry.Here it is:

I've got also "newest" drivers which Dell offer - DriverVer=07/19/2005,6.14.10.4363 - and I can't install the newer from Intel. (and the .inf file is ialmnt5.inf and it is the only .inf file there)

[Aaron_B_Intel]

Yeah, that appears to be the information for your laptop display. Not gonna help.

It's a Dell? :( They tend to have their own custom version of the drivers, and it's not as easy to modify them.

[zeq]

Oh no :( I've still hoped there is some chance :( But thank you anyway

[zeq]

Don't you know where I can ask some better informed people? I don't believe I'm the first one who want figure out this problem. Thanks

[Aaron_B_Intel]

The entechtaiwan link I posted above should work. The folks there have solved this problem for themselves.
