Not sure if it will help with a laptop, but the Intel fix file win2k_xp14323bb.exe certainly worked for me. Supposedly corrects a problem with the 945 driver not recognizing the resolution of LCD panels under some conditions. I got it from here:

I was looking for someone able to help me with my problem. It seems it is the only place in internet I can hope to find it.

I have problem with resolution on my screen. I have recently bought HP w2007v and tried to connect it to my sony Vaio (vgn-n38e) with intel 945GM Chipset.

For some reason image is blurred - it is not the matter of setting resolution - I can pick 1680x1050 @ 60Hz.

Windows shows as if I was displaying that resolution, however when I check on monitor OSD - it says 1400x900 @ 60Hz. (I checked myself and 1680x1050 fits exactly on my screen). Monitor was checked with other laptops and only mine has problem with it so at least I know it is smth. with laptop

I tried the trick with DTD setting in inf file (i don't think that applies in my case, but just for experiment) but it didn't help.

Other thing is I cant install latest drivers - when I download them they say - i have to look for ones from my computer manufacturer.. so I have to stick to version 7.14.10.1295. Maybe latest ones fix this problem, but sony support doesn't have them...

Pretty sure the "blurriness" at 1680x1050 is due toa panel fitting bug which was supposedly fixed on one of the 15.7.x releases, but if you're dealing with an older driver there could be problems in that case. My suggestion is to try to get Sony to upgrade their drivers to something more modern.

Other suggestion is to try the DTD trick with 1678x1050 (lower the third byte from 90 to 8E and raise the fourth byte by 2). I think the custom resolution is not subject to the panel-fitting bug, but that if you try to set a custom resolution of 1680x1050 you'll get contention between the driver's defaultand your customsetting andit's probable the default will take precedence.

Hey, is this where the cool kids come looking for help?

I've got a Dell Inspiron 6400 w/ an intel 945gm express that I'm trying to hook a Dell e288wfp 22"w/s monitor up to (native 1680x1050).

Problem is it won't let me get any higher than 1024x768 on the monitor.
The laptop monitor runs fine at 1280x800.

I've tried various different tricks that I've read online to get this working right... including trying every compatible driver (windows xp). It's weird because this laptop and monitor used to belong to someone else in my office and it worked fine for them. After they switched machines this machine was wiped and now it will no longer work.

Moninfo won't give me an useful information on the monitor but it will give me all the EDID info from the built in display (the laptop display).

Any ideas?
Thanks,
Sev

Thanks for the info. I eventually managed cheat a little bit andto update the drivers to the latest ones -15.7.3. It says 7.14.10.1409 for driver version. But it didn't help. Everything is still blurred. Is there any newer driver for this card? Is there another way of getting around this bug?

Yes, unfortunately it won't install on this laptop because it's dell and they want you to only use their specific drivers. I've dug around Dell's site as well and I just don't see anything similar for Dells.Unless you know a work around.

Aaron Brezenski (Intel)'s picture

I don't, particularly; however, I just saw this

http://software.intel.com/en-us/forums/showthread.php?t=57516#54898

which is how to do it on a Sony VAIO (another vendor with their own version of Intel drivers).

This metod works on Vaio. That is how I installed latest drivers from Intel. The bug you mentioned remained though. Do you have any other suspicion what maight be the cause for blurness on my screen and resolution mismatch? Windows shows it is set to 1680x1050 and monitor 1400x1050 - it makes me think there is some way graphisc card says monitor what resolution it is set at the moment - and it says it wrongly - if there would be a way of correcting that...

I was able to get the CS-028366 patch installed on this Dell by skipping the setup.exe. As soon as I ran the exe and it automatically unzipped files into my temp directory I updated the driver manually through device manager pointing at the .inf in the temp directory.

It installed and didn't give me any "Use Dell Drivers or else" messages. Unfortunately, no dice. It still won't read the monitor or give me the option to run it any higher than 1024x768. Also, when I first plug the monitor in... I can sometimes force the machine to go to a higher resolution (not 1680x1050 mind you... closest I can get is 1400x1050) but the monitor creates a virtual resolution (i.e. it still displays at 1024x768 but it will slide the screen around for the full 1400x1050). This was happening before I installed the new 945gm driver.

Hi Archibael,

I found this forum and felt that my resolution problem can be resolved now .

I have a desktop with Intel 945G graphics adapter and 'Samsung SyncMaster 920NW' widescreen LCD monitor. Monitor's native resolution is 1440 X 900. But I am not able to set it because its not there in Display Properties.

I am surprised to see that no EDID is being read from monitor. I checked with MonInfo and it returned the following data:

Raw EDID is not there.

Even EDID editor of ViewSonic showed - "Unable to locate EDID Data".

So is there any problem with the monitor?

I read your 'Custom Resolution' page and found that the resolution issue can be fixed with Modeline even if EDID is not there. I searched for Modelines of my monitor and found few different modelines:

Modeline "1440x900@60" 106.47 1440 1520 1672 1904 900 901 904 932 +hsync +vsync
Modeline "1440x900" 108 1440 1520 1672 1904 900 903 909 934 -HSync +Vsync
Modeline "1440x900_70.00" 126.98 1440 1536 1688 1936 900 901 904 937 -HSync +Vsync
Modeline "1440x900_60.00" 106.47 1440 1520 1672 1904 900 901 904 932 -HSync +Vsync

I am not sure which one is correct. However the maximum resolution which is there in monitor's driver inf and PowerStrip shows is 1440 X 900 at 75Hz.

I even tried with PowerStrip to get the custom resolution 1440 X 900. But I am not aware of other fields like porch, sync width, pixel clock etc so could not create a proper viewable resolution.

It would be helpful if you could let me know the DTD for 1440 X 900 to put in igxp32.inf.

Thanks & Regards,

Sumeet

Weird that the actual resolution is set to 1152x864. Huh.

To calculate DTD, use the tool suggested in

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

The panel at the left of that tool can be filled in with the Modeline parameters in order as they are listed, and the DTD will appear in the "Calculated DTD portion.

This was happening before I installed the new 945gm driver.

Did you try at any point to install a .inf file for the monitor (different from the .inf file for the graphics driver). Sounds to me like it's encountered what it thinks is a limitation of the monitor (.inf files for the monitor usually contain details on the limits of the monitor's horizontal and vertical frequencies, and are sometimes wrong about it)... or possibly there's some default behavior when it can't read the EDID and it assumes the monitor can't go over 1024x768 so it moves you to the virtual (aka scrolling) desktop. I don't have much else to offer here, alas. Sorry!

Hi Archibael,

I had set it to 1152 X 864 deliberately coz other resolutions were giving blurred picture.

But now the issue is resolved . Thanks a lot for the help. The DTD calculator is a nice & useful tool. I inserted the DTDs generated through modelines directly into registry by Registry hack. I have a clear display now at 1440 X 900 @ 60Hz and 1440 X 900 @ 75Hz. However other refresh rates like 70Hz gave blur display.

Anyways issue is resolved. Thanks for the guidance.

I am also interested to buy a 22" lcd monitor and all the information that u wrote helped me in taking a good decision.Thank you!

Alas, I can't find 1440x900 timings for your monitor anywhere, or even any indication in the user manual (or the monitor's own self reported EDID) that the monitor can do 1440x900.

Can you get someone who has gotten this working at 1440x900 to post Powerstrip or Modeline information?

Ok...I somehow got the 1440x900 to work on this monitor and here's the info from MonInfo...does this provide any more insight?

For that particular monitor, the EDID is saying it wants timings:

Thanks very much.

Senior Arch.,

I was hoping you might be able to give me some pointers regarding this issue. I was just surfing here at work in our IT dept. when I happened upon this thread. We have a couple of ladies in the office next door who just got new Viewsonic 1703wb's. Upon first connecting, it auto adusted to the native 1440x900 res. However, upon bootup the next day, the 1440 res was gone. Nothing a normal person would try has worked, and I myself am more of a hardware freak and builder, and minor network trouble shooter. I've never delved into registry tweaks, certainly not of the type you've been displaying here. Are there any drivers out there that would save me from having to run the monitor info prog. you've posted here? I tried to newest intel chipset driver release (as they are both on toshiba laptops using the 945gm), but it appears (if I read correctly) to resolve issues with digital connections, and theirs are connected using the standard analog. Any ideas would help.

Chris

wellsdaddy,

Supposedly the latest drivers (15.7 and later) should support 1440x900 without trouble. If not, you can add it using the DTD method detailed; best bet is to use the EDID given by MonInfo or the Information button in the Intel Graphics Tray and post it here.

Arch,

Thanks for the reply. I will venture into the MonInfo route should the drivers prove unworthy. I was just on the Intel website, however, and saw the latest graphics accelerator drivers for the 945gm were labled 14.xx.xx. What driver are you referring to thats 15.7 or later? Is this a beta driver for the graphics accelerator or is it a different type of driver all together. Thanks in advance for any help.

Arch, here is the display properties INFORMATION tab. Again, the viewsonic monitor is connected to the toshiba laptop with the 945gm chipset. In the display properties, the primary display is set as "monitor" and secondary is "notebook or laptop" Not sure if those settings matter, but just fyi. here is the INFO:

The fact that the viewsonic isnt showing up makes me think something isnt configured right, but I didnt do the initial config so theres noway for me to know what was done.

I guess it would help to mention also the laptop---->flatpanel monitor setup is running winxp pro. I found the 15.7 drivers I believe you were referring to, but they are for vista it would appear. Thanks again

Aaron Brezenski (Intel)'s picture

Yeah, sorry, didn't get that you were using WinXP.

Have you tried this yet?

http://www.intel.com/support/graphics/sb/CS-028366.htm

Interesting. The version I found the other day was build 14.32, and yet the date of 14.33 that you just posted is feb. 15th. I will definately give this one a go and check back in. Dont know how I missed that last week, but thanks much!

Sure. Which resolution do you want that the Intel driver is not providing?

Hello,

I hope you can help me I have HP compaq nx7300 with945 experess chipest family which supports resolution 1440 x 900, and I gota new external family HP L1908w. when I connect the labtop to the monitor, I can select resolution 1440 x 900 but what is happening is that I got a black hiden area (about half inch in the right of the screen which hides the clock and closing x in all windows application, I can't see anything in this area but i can imagine the position of the closing x to close any application). I tried to use another labtop with this screen, it works fine (labtop use R 965) and another Toshiba labtop and it works fine.

Here is the monitor data :

What is the resolution of your laptop screen? I suspect what's happening is either 1) the driver is using a generic 1440x900 that is not working well with your monitor, 2) the 1440x900 resolution your monitor is provided is not actually optimal for the monitor, 3) the resolution is mismatched between the laptop screen and the monitor and the OS/drivers are reporting that it's sending 1440x900 when it's actually sending something else.

I'd try using the DTD trick (found elsewhere on this forum) with a 1438x900 resolution based on the 1440x900 timings:

9A 299E D2 51 84 22 30 50 98 36 00 9A 00 11 00 00 1C

If it looks much better, you can rule out 2), and you could use this one instead. You'll lose 2 pixels on each line, but in the big scheme of things it's probably not highly noticable.

Hello,

thank you so much for your reply.

the resolution of the labtop screen is 1280*800 pixels. I did tried to change the DTD, but whenever i try to install the driver after change the DTD with the new one, an fault appears the the setup will be cancelled.

I tried also to uninstall the driver, the labtop used some thing called VGASAMA or something like that and the screen worked fine but without an ability to swap between the monitor and the labtop screen.

So, what do you think i shall do. if it posiblle you change the file for me and send the modified driver so that i install it, maybe I didn't understant well how to edit the required file.

it will be highly appreciated.

my e-mail is : noureldeen81@hotmail.com

Thanks again for your support.

Modifying the .inf file by hand can be error prone. I'd try DTDCalc, as discussed in

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

Should be able to paste the DTD I gave you into the "Reverse Calculate" tool, and then Write To Registry.

Hiyou are doing really a great job... I am also stucked with the same problem... Please sugest me what to do.. I also changed the inf file as archibael suggested in wiki but guess missed something.. hereis my moninfo data... I have a 19" wide samsung sync master monitor,

Hardik,

It seems from what other posters with your monitor have done that you should try running on DTD

97 29 A0 D0 51 84 20 30 50 98 13 00 00 00 00 00 00 1E

If you edit the registry directly or use the .INF file, don't forget to add "37 01" to the end.

Hi,

My monitor has a bogus edid, my monitor is an al1916w from an oem acer workstation
my pc is a shuttle sg31g2

what mode should i use to get 1440x900 @75hz ?

I tried writing the hex above but i think it didn't accepted, funny thing this was workig around january, then
I bought a nvidia card and a 22inch, I recently sold those since I'll be getting a bigger monitor and faster gpu, but when I tried hooking this spare LCD (Acer al1916w) and it doesn't support 1440x900 anymore,

here's the raw edid

05 82 00 54 05 82 00 64 05 82 00 74 05 82 00 88

is there such resolution as 1400x900 ? or is it a mistype, i've search google and there are people have those resolution

and also I manage to get 1440x900 @60, its a little bit squisched,
so i'm thinking is my monitor's native resolution 1400x900 ?

nway just wanted to get a 75hz setting

Community Admin's picture

1440x900 is 16x10 (not 16x9). It's a legitimate resolution, but if you are trying to fit a 16x9 image to this resolution and still fill the screen you will have the slight "squishing" you report.

You are correct in that the EDID you posted is garbage. What DTD did you use to get 1440@60Hz? Youmight be able to just take the first hex numbers in that string, invert their order, multiply by 1.25, invert them again.

So if your DTD is

4A 23 00 1D 04 ...

Take

2348 (hex) = 9032 (decimal)

9032 * 1.25 = 11290

11290 (decimal)= 2C1A (hex)

So, assuming this were a working 1440x900 DTD rather than me pretending, you could replace the first two digitswith 1A 2C and the only thing that should change is the refresh rate.

Of course, this assumes the TV could accept that, but it's worth a try.

Hello everyone,

I am in desperate need of help. I have a toshiba a105-s4114 and am trying to use a 19" Acer lcd with resolution 1440x900

Your monitor is advertising itself as 1280x800, which would explain why you're not getting 1440x900 available. You might want to try 1280x800 instead.

That's an easy one. Your DTD is

28 3C80 A0 70 B0 23 40 30 2036 00 06 44 21 00 00 1A

You can use it by entering it into the registry (append 37 01), putting it in the .inf before install (append ,37,01), or pasting it intoDTDCalc (append nothing).

Thanks for your fast reply!

Sorry, first time this kind of problem, so which registry key should I change?

I do not understand why it is saying that. The monitor's max resolution is 1440x900.

peet111174,

I'd personally use the DTDCalc tool... http://software.intel.com/en-us/forums//topic/56423

But if you want to modify the registry by hand, you can use the instructions at

abw11:I do not understand why it is saying that. The monitor's max resolution is 1440x900.

Could very well be the laptop's screen being reported. Can you go to the Intel Graphics Tray, Information button, and click "Save To Disk" and post the result here?

Hi archibael,

I too am having a problem with the resolution.

My monitor is Viewsonic VA1926w. Resolution is supposed to be 1440x900, but in the display settings it only goes up to 1280x768.

I've been reading this thread, and have tried to look for my EDID in the registry (I'm assuming it's under HKEY_LOCAL_MACHINESYSTEMCurrentControlSetEnumDISPLAYdefault_monitor). the only thing I find there is BAD_EDID.

when I run moninfo, I get:

Monitor
Hardware information........ n/a
Windows description......... ViewSonic VA1926w SERIES

Display adapter
Adapter description......... Intel 82945G Express Chipset Family
Adapter device ID........... 0x27728086
Display settings............ 1280x768, 32bpp

User/computer information
Registered user name........ Dushansky
Registered organization..... n/a
Network user name........... me
Network computer name....... DUSH
Windows version ............ Windows XP
Windows build .............. 5.01.2600 Service Pack 2
Installation date .......... 27/05/2008 12:00:00

what could be wrong?

Many thanks,

Meron

You are right, it is the laptop screen resolution being reported. I am kind of having trouble doing things on the laptop without the monitor because the screen is broken and will only light up if the lid is open about 2 inches. lol

You're not getting the EDID read. I'd try

http://www.intel.com/support/graphics/sb/CS-028886.htm

A lot of Viewsonic monitors seem to have this problem, if the number of issues on the Intel forums is any indication, so that driver may not assist you.

If the alternative drivers don't work at getting the EDID read,I suggest attempting toget it read on another systemand applying DTDCalc or a direct registry edit to force 1440x900 using the techniques mentioned in the "Custom Resolutions on Intel Graphics" thread.
