Inf-editing help needed: Resolution of 1680x1050 with a 945GM

[mail3]

Hello,

I just bought a 22" Acer Widescreen Monitor and it is sometimes working with my PC. 3 times up to now - by chance... I just read this, but I don't know what to do, because the DTD is not in my driver. Can someone help me editing my .inf file to get this thing working for every time? I copied the MonInfo-report and my driver below.

This is from MonInfo:

Yeah. I've copied it. You can delete it now so it doesn't get spam farmed or anything. I may have something for you later.

[f00sh00]

Okay thanks, i really appreciate you helping me out.

So i shouldn't go ahead and uninstall my drivers and reinstall the new drivers? I guess i'll just wait for what you have to say and do that as a last resort.

[calivyper]

Hi,

Is this the same driver for the 945GM/GU GMA950 chip ?

This what I have in my toshiba satellite A105-S4094. The funny thing is that when I installed the driver for the 22" hp w2207 lcd, the w2207 works fineand the 945GM card outputs 1680x1050 to it and displays that resolution as a choice. But when I connect the Viewsonic 22" lcdVX2235wm and install the viewsonic drivers, the card no longer shows 1680x1050 as a resolutionfor use withthe viewsonic.

So what is the hp driver doing right that the viewsonic driver is not ?

Is there a link for an updated 945GM/GU driver that has all of these wide screen resolutions ?

Anyway, any help would be appreciated.

Thank you very much.

[Aaron_B_Intel]

Difficult to determine why some monitors are working and others are not. I suspect there's something non-standard or out of spec about how some companies time their EDID reads, and that when they are queried by the Intel drivers they're coming too late and the driver times out on its checks. But I'm guessing, here.

Assuming you can get an EDID out of your monitor and a driver which is newer than 14.25, you should be able to get the monitor to work with registry tweaks.

Hi archibael:

I have a Dell 1520, hooked up to a Viewsonic VX2235. Same issue as most i have seen on these blogs. Can't get 1680x1050 to work.. I have used the Mon Info, but cant get any results out of it to be useful (( as you satated in a post in Aug )) I followed some of your directions for attempting to edit the INF,..(( HKR data not in the INF )) searched registry...(( Can't find anything in the reg for DTD values )).. I am at a loss .... using Vista Ultimate.... Tried getting lates intel drivers for the chipset...and the inf instal utility wont let me install ((( Dell again ))

I can however get 1680x1050 without monitor connected...but once i hook up to the vx2235....cant get the resolution. I am pulling my hair out on this ......any suggestions...

below is info from the intelinformation med graph driverwithout viewsonic vx2235 hooked up.... i can't seem to get the info when it is....

I am open to any details you can provide....

Brian....please email back ...qtrmile69@hotmail.com

I'm a little confused... 14.10.1272 (as found on the Dell website) has the DTD values in the registry. I know regedit can be annoying in that it only searches the structure you have highlighted... try highlighting the top level inregedit("My Computer" in XP, not sure what it is in Vista) and doing your search from there.

Hello,

I have the same problem with a laptop with 945GM chipset and an external monitor LG M208WA: the 1680x1050 resolution is not displayed as possible.
I'm trying to solve with the suggestion posted here, but the link to instructions http://isnwiki.jot.com/WikiHome/Articles/111111431 is broken (the browser remain waiting for isnwiki.jot.com).
It's possible to hope in a new driver version fixing this bug?

[Aaron_B_Intel]

The Wiki has moved. Try

softwarecommunity.intel.com/Wiki/Graphics/239.htm

Let me know if you have trouble.

[qtrmile69]

OK..... I found the INI file.... I found the HKR entries ... Now ....what do I enter to get the 1680 x1050 setting with the adapter when using the VX2235 ???

I ran moninfo....but not getting edid from monitor when connected ...

I know there have to be other with the same monitor and same 965gm chipset i have to add to the ini .....

I would go as far as to send you the ini to mod if you could

here is the extract from the INI

Brian,

Fortunately, we've encountered your monitor before, so I know the DTD.

Fill in the DTD_1 entry with

21,39,90,30,62,1A,27,40,68,B0,36,00,DA,28,11,00,00,1C,37,01

Some laptop vendors are evil and specifically disable certain resolutions-- and 1680x1050 is a common one to disable (in all fairness I think they do it out of ignorance and not malevolence, but I digress). If 1680x1050 doesn't work, try 1672x1050:

21,39,88,38,62,1A,27,40,68,B0,36,00,DA,28,11,00,00,1C,37,01

[qtrmile69]

I appreciate it greatly .... Thanks for the 411

[qtrmile69]

All: If your Running Vista, and you have a Intel GM965 and happen to have a Viewsonic VX2235 hooked up to it...I have the solution now.

Thanks to "Arch" ---

First: edit your inf file -- If a dell, get your latest drivers, and run the .exe to the point the files are extracted. (typically the file is named c:DELLDrivers"driver download name"Graphics"inf file"(only one in there)

Second: edit the .inf with:
HKR,, TotalDTDCount, %REG_DWORD%,5

HKR,, DTD_1,%REG_BINARY%,

21,39,90,30,62,1A,27,40,68,B0,36,00,DA,28,11,00,00,1C,37,01 ;1650x1080...interlaced

or

21,39,88,38,62,1A,27,40,68,B0,36,00,DA,28,11,00,00,1C,37,01;1672x1050...Interlaced

save, and continue with install. (may have to select "Install Driver Anyway")

Restart, and see if resolution is in there.

If not, run regedit, and search for DTD_1

Once you find it, do modify binary, and addDTD from above to add the 1680x1050 or 1672x1050 DTD's.

Scroll down to the TotalDTDCount, and modify, and enter 6. The reasoning is that there are additional entries that go from DTD_1 through DTD_6. (( I suggest those entries where there are 6 DTD's to add both the 1680 and the 1672, and the ones that have DTD_1 thru DTD_5 to add the 1672. ))

You will have to use F3 to find all the occurences, but once you have your DTD's added, and modified your TotalDTDCounts, and restart....your in business.....

I would like to thank "archibael" for his latest info, and to everyone who has posted their info. It helped, and I am in business with good resolution.

Good Luck

[Aaron_B_Intel]

Glad it worked, Brian.

[msjones1985]

Hi,

I too have the the AL2216W which should run at 1680x1050 running on a HP6710B with a x3100.

I cannot get the card to output to 1680x1050. I have changed the DTD counts/strings as mentioned in a previous post, but windows gave me an error saying that I am using old drivers. This is not true, I am using the latest intel drivers for windows vista business 32bit. I had to reinstall the latest drivers downloaded from intel.

Does anybody know the right DTD code for windows vista?

Thanks in advance,

Matt

[Aaron_B_Intel]

Matt,

If you're getting an error for "old drivers", the DTD's not the problem (and it's the same DTD for both Vista and XP). What drivers are you using and where did you get them from?

AB

[msjones1985]

Hi,

I got them from the intel support site??

Matt

[Aaron_B_Intel]

Go to the Intel Graphics Tray, click on Information, and then Save to File. Paste the result here.

[msjones1985]

Hi,

No need to post the output, I hadmissed a DTD string in the registry. After reinstalling the new drivers and re-inputting the DTD strings I am now working at 1680x1050!

Thanks alot guys!

Matthew

[Aaron_B_Intel]

Good to hear!

Hi
I'm having the same exact problem, I'm using a Dell Inspiron 1505/6400 and trying to run a Westinghouse 22" (LCM-22w3) widescreen monitor. I have the most updated drivers for video and the BIOS. I tried changing the registry information like the people in the posts above, but there was no change. I also have absolutely no background in coding or anything like that so I was unsure how to alter the VBios hexidecimal code like the wiki explained. I've been trying to fix this for over a month and am extremely thankful for any help.
