945GM not working with my 1680x1050 monitor

945GM not working with my 1680x1050 monitor

Hi, just got me a nice new shiny tft, but the intel driver does not list 1680x1050 as a resolution. Usually installing the correct monitor drivers should fix this but, xp does not show "new hardware added" on my laptop(tosh SP-A120) when i plug it in as it does when i plug it into my desktop pc. I have installed the latest display drivers from the intel downloadcenter(version 6.14.10.4820, 16/04/2007) but this still has not resolved anything

Interestingly (or not) when I try to install the monitor(viewsonic VG2021wm) drivers on the laptop, the install fails because it does not find the monitor installed

at the moment running 1400x1050 but text is being streched horizontaly, I do alot of development text based work and it is hard on the eyes

Anyone any ideas???

Manney,

Please run MonInfo and report back with the EDID results. (http://www.entechtaiwan.com/util/moninfo.shtm)

From there we should be able to help.

I'm having the same problem with my new LCD! I want to use 1680x1050 (60 Hz) and 1440x900 (75Hz), but those resolutions are not available.

I run MonInfo, and these were the results.

Would really appreciate some help ;) Thanks in advance!

Forgot to say that my tft monitor is a fujitsu siemens scaleoview l22w-3 (22'').

Are you sure you're selecting the right monitor? MonInfo has a dropdown box at the top, allowing you to select which monitor it scans. Your results look like they're from a laptop flat panel rather than an external monitor.

The last part seems to be from the notebook lcd, because the one i'm connecting is not 13''! Can you help?

manney,

You'll want to use the Wiki here http://isnwiki.jot.com/WikiHome/Articles/111111431and use the following DTD for 1680x1050:

21 39 90 30 62 1A 27 40 68 B036 00 B1 0E 11 00 00 1C

ajfer,

Yeah, that appears to be the laptop monitor: it's looking for 1280x800. Damn, I really dislike when monitors are stingy with their EDIDs.

Can't find a Modeline for your exact model, but maybe we can find something similar.

Thanks archibael,

that worked a treat, after I realised that cut and pasting the values in your post directly into the inf was causing the driver install to fail because of there were no commas between the values :-)

Thanks again

Manney

archibael,

First, thanks very much for your attention.

I manage to solve the problem in another way. It seems like the reason for this problem was due to the cable I was using. The laptop's only graphic connection is DVI and I using a VGA cable (because it was the only one the tft came with) and one DVI-VGA adapter.

I bought a DVI cable, connected it and the intel software detected a digital lcd and all the resolutions available are now correct!

Thanks again for your help and time spent!

Great news, ajfer. Sorry I couldn't be of more help, but glad you've got it fixed.

-------------------------------
I can;t use a DVI cable since the Toshiba doesn't have a DVI connector, so the last person's solution can't work!

Any ideas - I'd be very grateful

Rough one. It's another IEGD driver solution, and it's much more clumsy than the 915/945/965/G3x... I can't make this my number one priority, but I'll look into it when I have some time.

Great, thanks, I'll look forward to any help.

Hey archibael,

Thanks in advance!

Actually, your problem is more like olegliber's in that you are using the 855 chipset, which uses a different method of specifying custom resolutions. Moreover, your monitor, unlike his, is reporting 1600x1200 as its resolution, even though you say you want 1680x1050. AsI told him, I will work on this soon, but I can't dedicate the time to it right now. Sorry!

Note that the following method is for chipsets predating the 915G/910G. It can be used with later chipsets all the way through GM965, but in my opinion it's more kludgy of a process and you're better served on newer chipsets following the Wiki on how to modify the .inf DTD values directly on the standard Intel drivers for those chipsets.

This method uses Intel's embedded graphics drivers, which are meant for specialized applications. They may not have as much functionality as the normal Intel Graphics Drivers youwould ordinarily download from your laptop vendor or from Intel. These tools are meant for system builders and I do not recommend doing wacky things like generating your own VBIOS. (Although if you are clever enough to be able to incorporate that into your regular BIOS, you shouldn't even be reading this because you shouldn't need my help!) Use this to generate graphics drivers only in the event you can't get your monitor resolution in any other way on an older chipset.

Okay olegliber and Benson, here we go. The new embedded graphics drivers have made it rather easy (from my perspective) for Do-it-Yourselfers. If it works, that is: I don't have the chipset, so I'm just going by what the instructions say.

Go to the Intel Download Center:

http://downloadcenter.intel.com/default.aspx

Type "IEGD" into the search window. Up will pop a list; grab the IEGD 7.0.0 driver. Download it. Double click on it, extracting it to some directory on your machine.

Find the folder you extracted to, and double click on

iegd-ced.exe

A dialog will open up to generate a "custom driver" for your purposes. Click the New Configuration button. Name your configuration. Doesn't matter what. Select your chipset (855 or 852 or what have you) from the pulldown menu, and choose how you want this to operate: as a single monitor, as a dual head monitor, as cloned or twinned monitors, etc.

Click "Enable" by "Display Detection", then choose which port type your monitor is on. "CRT" is VGA, most DVI and TV stuff will be on SDVO, and laptop monitors will be on LVDS. DVI might also be on LVDS... not certain. Anyway, click on the monitor type(s) the resolution will apply to and send it to the Port Order. Click Next when done.

Name the Port. Don't think it matters what you call it. Under EDID options, leave everything checked that is, and add checks in both "Use user defined DTDs" as well. Under "Select DVO device", I think for most purposes you're going to check "None". If you have an SDVO DVI or TV card you'll need to figure out what chip is in it and select that. Click the "New DTD" button.

First name your DTD. "1680x1050@60Hz" is a good name, but you could call it "MyRez" and not run into trouble.There are several different ways to specify a DTD here; if you want one your monitor is telling you it supports natively in the EDID, go with the DTD Type of "EDID Block". Scroll down to the EDID Block section and fill in the 18 blanks withthe DTD you want. olegliber, for you it's

7C 2E 90 A0 60 1A 1E 40 30 20 36 00 B1 0F 11 00 00 1A

Benson, your monitor is claiming it li
kes 1600x1200 timings. Don't know why, if its native rez is 1680x1050, but if you're willing to accept 1600x1200, fill in

48 3F 40 30 62 B0 32 40 40 C0 13 00 98 32 11 00 00 1E

If this is unacceptable to you (looks distorted, etc.), you might want to try choosing 1680x1050 timings from the Philips 200WS:

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

I couldn't find a Modeline or DTDs from your exact model, sorry.

Alternatively, instead ofselecting "EDID Block" for DTD Type, try selecting "Simple Parameters",and then filling in HorizontalActivewith "1680" and VerticalActive with "1050". Refresh in Hz should be "60". That's about as simple as it gets... but if your monitor is finicky it won't accept that, so be forewarned.

When you're done specifying the DTD, click Finish. You can create several DTDs this way, each with a different name, and when you return to the Configuration page you can checkbox the ones you want available. You can also choose which gets given the "Native DTD Flag" using the pulldown box if you want that resolution labelled "Native" in the driver.

Once you've chosen those, click the Finish button. You now have a Configuration.

Click the New Package button. Name it whatever you want. Choose your target OS (Vista isn't available; you'll have to use XP drivers in Vista, so check Win2000/XP/XPe) and check the Configuration file you'll want touse (there's probably only one: you justmade it). Click Finish. You now have a Package.

On the IEGD Configuration Editor sidebar, expand the + next to "package". Click on the package you just created, then click the Generate Installation button. You will now have an Installation, aka a custom driver. In fact, it even puts it in a .zip file for you. You should be able to open this .zip, click setup.exe, and have it install for you.

The biggest area for concern I have here is which port to choose (CRT? LVDS?) and how to deal with multimonitor situtations... I'm sure one monitor is relatively easy, but you're on a laptop, and that means you might want more than one.

I hope this helps you guys.

Archibael, huge thanks. It was a bit of a struggle - first I ended up with only the external monitor working, and had to repeat the process to include settings for the laptop screen (1024x768). Then the external screen insisted on being the primary monitor, so that when the laptop was disconnected I couldn't log on. But now all is good. It would be much better if laptop/monitor companies provided drivers in the first place!!

Thanks again

I am also having this problem. I have a 945gm/gu. I trid the inf modification but failed to get it to work. Any suggestions would be greatly appreciated.

I am trying to achieve the 1680x1050 resolution.

Lester,

Hopefully the latest 14.31.1 drivers will work for you.

Make sure

21 3990 30 62 1A 27 40 68 B0 36 00 DA 28 11 00 00 1C37 01

is in all instances of DTD_1 in the registry and that TotalDTDCount is set to 1 in all the instances as well (there are a lot, so keep hitting F3 on your search for "DTD". :) )

Alternatively, if your notebook BIOS is refusing 1680x1050, use 1672x1050:

21 3988 38 62 1A 27 40 68 B0 36 00 DA 28 11 00 00 1C37 01

Archibael,

Thank-you for your quick reply, much appreciated. I will try the suggestions and post back.

-Lester

You are the man Archibael!

Thank-You very much. It worked. Much appreciated.

-Lester

Thanks archibael for the thoroughly written reply! I tried all that you mentioned, but when I try to install the driver throught the setup.exe file that is created (in the zip), I get an error in during the installation: "All the components are not installed correctly. Please try installing again." and if i restart the computer, I get something like the blue screen of death telling me to shutdown the computer because I driver is looping too much and won't stop. I have no idea what to do and my Dell warranty is up. Any help would be appreciated again!

I'm low on ideas, Benson; I'm barely competent when it comes to the modern chipsets-- when it comes to the older stuff, I'm flying blind because I don't have any hardware here to experiment with. All I can think of is that maybe you chose the wrongchipset when you created the driver? Or that Dell has done something "special" which makes this break.

You might want to ask people on the Powerstrip Forum thread which deals with this, now that it's active again:

http://www.entechtaiwan.net/forums/viewtopic.php?t=3363

They have the older hardware and have been able to get lots of those machines to work. Sorry I wasn't more useful.

hi Olegliber,

i'm having the same problem as you had with the laptop when it is disconnected. what exactly did you do to fix the issue with the laptop not responiding when you were disconnected? and what display settingsdid you:single, clone, twin, or independent head? any help here would be great! thanks!

archibael,

I have 2 questions to ask:)

1. Would you tell me how to find or compute the DTD string from the MonInfo results?

2. I use the IEGD way to build a driver, so the UX27CN(945GM) supports 1680*1050. But it seems something wrong because the laptop cannot enter the hibernation.

Thx in advance!

1. You can read my article at

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

That covers the first block of data in MonInfo. The second block (for HDMI) is more complicated and you can either read the Wikipedia article on the CEA Extension Block at http://en.wikipedia.org/wiki/EDIDor just post it here and I'll help you decode it.

2. Is there a reason you've been using the IEGD? The 945G can get custom resolutions without it.

1. The Raw EDIO base which is reported by moninfo is below:

Raw EDID base
00: 00 FF FF FF FF FF FF 00 05 E3 10 22 40 A4 00 00
10: 2F 11 01 03 68 2F 1E 78 2A C3 D0 A4 55 49 9A 26
20: 13 50 54 BF EF 00 61 4C 81 80 81 8A 81 8C 81 40
30: B3 00 01 01 01 01 08 39 90 30 62 1A 27 40 68 B0
40: 36 00 D6 2C 11 00 00 1A 00 00 00 FD 00 38 4B 1F
50: 50 11 00 0A 20 20 20 20 20 20 00 00 00 FC 00 41
60: 4F 43 20 32 31 30 56 0A 20 20 20 20 00 00 00 FF
70: 00 45 34 32 37 42 4A 41 30 34 32 30 34 38 00 CA

So, the string should be

08 39 90 30 62 1A 27 40 68 B0 36 00 D6 2C 11 00 00 1A

Is it right?

2. Someone said the latest intel driver for 845GM directly supports 1680*1050. But after upgrading I still cannot see it from the list.

By the IEGD way I can use the 1680*1050 res, but as I said, itcauses something wrong with power, like shutdown(halt every time) and hibernation(forbid enter).

Any suggestion?

Thx in advance!

1. That is indeed the right string for 1680x1050.

2. Is it 845GM or 945GM? For 845GM, you're right: IEGD is the only way to get custom resolutions. For 945GM you can use the regular Intel drivers, though. I'm not sure what is going on with halt and hibernate for you, but it's possible it's the IEGD drivers causing problems that would be fixable with the regular drivers instead.

UX27 (called UX280p or UX71 out of PRC) is 945GM.

The lastest intel driver for 945GM should directly support 1680x1050, but in UX27 it cannot. Strange but I don't know why.

IEGD driver can let 1680x1050 displaying correct. But it causes losting of some useful functions like hotkey support.

I modified the igxp32.inf in intel offical driver, replace the DTD string, upgrade to this driver, then use PowerStrip to get the 1680x1050 res at last.

(I tried directly using PowerStrip before upgrading to the modified driver, failed)

Glad you got it working in the official driver. Yes, Powerstrip does not fully support Intel graphics. It's good software, but in this case you're better off without it.

hi all

can u please help me with my problem. i have a toshiba laptop and the monitor is damage so i have to replace my monitor. but when i replace my monitor the resolution is not very clear. its like im using an lcd infact it is crystal display

What resolution are you using on that machine which looks bad?

Your monitor appears to want 1280x800. If you're not getting that, you can force the issue by using DTDCalculator with the following settings:

EA 1A 00 A0 50 20 17 30 0C 30 43 00 00 00 00 00 00 1E

my resolution is 1024x768 and it is the maximum resolution.. do u think i bought adifferent model of monitormr. archibael.. is this digital flat panel is an old model ?and also how can i force that DTDCalculator.. can u please help me.. thanks in advance

Use the tool described in

http://software.intel.com/en-us/forums//topic/56423

and use the string of hex digits I provided in the last post.

hi archibael i already installed the DTDcalculator but i cannot run the application because i need to install NET Framework V.2.0.50727.. but when i install this net framework there is an error again which is Content.IE57U40A61Kdotnetfx(1).exe is not a valid Win32 application.

can u please help me with this one.. thanks

Huh. Hadn't heard that one before.

Well, regardless, you can still stuff it in the registry manually. Tack on a "37 01" to the end and stuff it in every instance of DTD_1 you can find in the registry. At the same time, change all instances of TotalDTDCount to 1. Reboot.

delete all internet files in IE

then chkdsk /f c:

then reboot

Well I read over the DTD wiki and did it but it still does not show up as an option. I have 945 by the way. Another problem with my Moninfo is that it does not dectect the name of the monitor or its native resolution like many others. I have the same monitor as the guy in another post (a few post down from this one i believe about editing INF file. I followed the steps there and installed the new driver, but still I got nothing.

" Is there a reason you've been using the IEGD? The 945G can get custom resolutions without it."

How to get custom resolution ?
I use ASUS P5GC-MX + e4500

Regards,

happyxix,

Tell me the steps you're following and what you're seeing. Could be the BIOS, in which case you have to tweak the resolution a bit to get around it.

Hi Archibael,

My name is Ric. I have the similar problem as Olegliber with my
setup: Toshiba portege M300 (not M100), Intel extreme graphics 82852/82855 GM/GME and a Samsung Syncmaster 226 BW (not 206BW) (1680x1050).

I read your post of 09-12-2007, 4:41 PM 30240558 in reply to 30240507. I could not find IEGD 7.0.0 driver but found and used IEGD_8_0_GOLD_1063 instead. I produced a custom driver as described and installed it.

Now neither my Notebook-Monitor nor the external Monitor are working. I have an image for a few seconds when Windows is booting but then all goes black.

Any help would be much appreciated. Many Thanks.

Rico

Hi Archibael,

I just picked up a new monitor and it seems I am having

a similar problem with getting my desktop to support

a 1680x1050 resolution (I have tried it in 1600x1200 and it

won't do). My machine has the 845G chipset and the info

from moninfo is below... I am hoping this is something I can fix

as I like the monitor. Anyhelp/suggestions would be appreciated.

For your chipset I recommend the aforementioned IEGD driver. You can use the settings from your monitor in either DTD format:

21 39 90 30 62 1A 27 40 68 B036 00 D9 28 11 00 00 1C

or in Modeline format:

Modeline "1680x1050" 146.250 1680 1784 1960 2240 1050 1053 1059 1089 -hsync +vsync

It's a steep learning curve, but there's no simple way to do it, unfortunately. :( Sorry.

Hi Archibel,

I am having a similar problem, I have tried pretty much all the solutionssuggested in this forum but could not get it fixed. Please help me out.

Ibought a 19" Dell monitor which supports1440*900resolutionto use with my laptop which has945 Express Chipset, butitonly goes up to1280*1024.

Let me describe what I have tried to fix this problem.

1) installed the latest driver for theadaptor (Intel graphics media accelerator driver for mobile v15.8).After installation, there is a added menu when I right click on the desktop which displays a window that contains all the information regarding the external monitor. It shows the correct list of resolution modes supported by the monitor, so the driver seems to know that the monitor supports 1440*900, but it does not show up in the drop-down list where I can actually choose the resolution mode.

2) From the EDID (attached below) I could read off the DTD, but igdlh.inf (I am using Vista Business) did not have any entry that contains the word "DTD". I could not find it using Regedit either.

3) Using the DTD calculator, reverse calculation using the above DTD seems to work fine but "Write DTDs to Registy" will generate a error message that it does not have the permission to access the registry. (Iwas logged on as adminstrator andthe antivirus program was turned off.)

Any idea what more can be done?

Best regards,

BJ

Hi all,
I also was having problems setting up my monitor and could not get it to work with the information provided here, some confused so I don't know if I did any one step wrong. I juat wanted to let you people know that I while looking for alternative solutions I found a program, PowerStrip, that lets you customize the screen's resolution. Though I should share this for people that were or are frustrated like I was.
