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.

The DTD for your monitor I got from a Linux forum:

21 39 90 30 62 1A 27 40 68 B0 36 00 D9 28 11 00 00 1C

For the hex impaired, I highly advocate the use of the software discussed here:

Hi Archibael

I read some hours about that topic and tried the regedit thing. It did not help.

I use a Asus PW201 with Vista and 965 Express graphics card.

Can you help me?

Would be great

Werner

[Aaron_B_Intel]

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 .....

There were indeed:

Change these:

HKR,, DTD_1,%REG_BINARY%, 01,1D,80,18,71,1C,16,20,58,2C,1A,00,00,00,00,00,00,86,37,01;1920x1080@60...Interlaced

to

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

If you find that this doesn't work, it's probably because the registry is not being updated by the installer for some reason; in that case, use regedit to modify the registry directly for TotalDTDCount, DTD_1, and DTD_2. Remember that there are a lot of these, so use the Find function in regedit (F3) until you are sure there are no more you have not modified.

Reboot after the registry gets modified and you should have your monitor settings.

Hi,

unfortunaletly the link to the wiki does not work any more. Is there a new one or could anybody please post the wiki?

Thanks a lot, Tobi

Hi,
I edited my registry
I change all DTD_1 to 21,39,90,30,62,1A,27,40,68,B0,36,00,DA,28,11,00,00,1C,37,01
I change all DTD_2 to 21,39,88,38,62,1A,27,40,68,B0,36,00,DA,28,11,00,00,1C,37,01
and tolalDTDcount to 2
But after reboot I still have 1024*768 as maximum resolution for my 2232BW ( samsung )-
My pc is a compaq preasario c737EL.

I tryed to install also winvista_158bb.exe. Intel relases this driver to enable 1680*1050 resolution on 965 Express chipset. Nothing change.

I have also powerstrip but I can't do nothing. I can't add a new resolution.

What can I do now ?

[Aaron_B_Intel]

Two things...

1) in the registry, are the numbers comma delimited? In the .inf file they should be comma, but in the registry they should just be one after another.

2) Does your monitor have a driver? Like a Samsung.inf file? It might be adding limitations where there needn't be.

Using the DTDs and having Powerstrip installed are mutually exclusive, so you might want to deinstall Powerstrip if it didn't work for you.

[carnauser]

Thanks archibael.
I solve the problem with DTD Calculator . Now i can select 1680*1050.....but first with another CRT monitor!!!

I'll explain better :

1 ) I connect a crt montor
2) I can select 1680*1050 with intel control panel ( not supported by 17" crt monitor)
3) I turn off the crt and plug-in my Samsung 2232BW.

Now it work perfectly at 1680*1050 until I turnoff my laptop....

If I connect first Samsung 2232Bw I can only select 1024*768 as maximum resolution.

I unistalled samsung driver.


Why is it possible ?

Hp answer me that the adapter does not support this resolution.......................

[Aaron_B_Intel]

Yes, HP is clearly wrong when it claims there's no support for 1680x1050.

For some reason Intel drivers after about 15.6.1 or so are struggling to maintain resolutions beyond a reboot. In 15.7 the drivers changed the way they do mode persistence, and it is my opinion this somehow messed up resolutions in general.

Of course, I have neither source code nor a decent debugger, so I am no certain what change was made to screw this behavior up.

[carnauser]

sorry lan problem / double post

[carnauser]

Great archibael .... :(

Is it possible to download somewhere some old drivers to solve the problem ?

Now I use 158bb drivers.

Thanks a lot.

[Aaron_B_Intel]

I think the ASUS website has 15.6.1. Intel used to keep a set of older drivers around if you wanted to go backward, but they seem to have ended the practice.

[carnauser]

I hope this can help someone.

I solve my problem...it wa a really a stupid problem.
It was the cable.
This, is the pins disposition in my new cable...

| O O O O O |
| O O O O O |
| O O O O O |

This is the pins dispostion in my last cable...

| O O O O O |
| O O X O O |
| O O O O O |

the X pin was missing both side, but the cable was not broken or damaged, it has been made in that way.
I checked in the shop, where i buyed it, and a lot of VGA cables are like it.
Now I can use 1680*1050 and the video card recognize the monitor and all its proprieties.


Maybe some one has the same problem....

[helenchennewmarket]

archibael and others

The solution you provided here really solve my problem (I have a Dell Latitude D630, Intel GM965 card and ViewSonic VX2035wm LCD.

I first used regedit method and changed DTD_1 and DTD_2 and the totalDTDCount number to 5. However, it does not work. I later went into the driver's INF file, in my case, the file is in C:DellDriversR181739Graphicskit12928.inf (I guess the number changes according to each vendor's agreement with the company - I have a company-provided laptop). Then I re-executed the driver exe file, and the magic has finally arrived!

Thanks so much for all who contribute information here. I found themvery helpful!
