1440x900 resolution on 945GM (GMA 950)

[brymaster]

I'm trying to get my external LCD widescreen monitor to use 1440x900 with my laptop. Here's my specs:

Windows XP
Toshiba Satellite A105
Intel GMA 950 with 945GM/GU
AOC 19MVWk 19'' LCD

I'm not positive that my LCD reports any EDID information and I'm trying to modify my igxp32.inf file like others have done but I can't figure out the DTD hex codes nor find any modeline information. Any help with this would be much appreciated! I noticed archibael seems to be the expert around here and I'm hoping to catch his attention ;)

Very glad it worked for you, abw11. I know it can be a struggle, but sometimes it's worth it.

This problem is driving me crazy!

We got in about 20 Acer x173w monitors and hooked them up to our machines. Half of them that we hooked up to the HP DC5700 machines worked out of the box. The other half wouldn't show 1440x900 as an option. Sometimes installing the most recent driver worked, other times it didn't.

Searching for a answer to this problem I came across this forum two weeks ago, read the wiki on how to do it as well as all 6 pages of this post. Someone else had posted the DTD for the x173w so I modified the inf file and installed it and lo and behold it worked.

A few days ago I found another DC5700 that had this issue, but after I installed the drive under a local admin account and then installed the modified driver. I left after the install was done and the user called me up the next day saying it still didn't give her the option of 1440x900. I thought this might have to do with the fact that she logged in as a user and not a admin so I put it on my "To Do" list and haven't gone up there to work on it yet.

Skip forward to today. I put my laptop into my docking station (a nc6400 with the same graphics chip as the DC5700, the dreaded GM945) and I no longer have 1440x900 while running in "Dual Monitor" mode for my desktop. The odd thing is my LCD on the laptop runs at 1440x900 and is fine, just the Acer x173w doesn't work.

So I downloaded the newest driver since the laptop is Windows Vista and the Desktop is XP(modified June 20 somthing) and made the same modifications, reboot and I still don't have 1440x900. I have posted exerts from my INI files below.

One of my techs here also has a HP laptop (HP Pavilion dv6000) and he had the same issue but he had a different graphics chipset. He found a monitor driver for the Acer and installed it and now his works fine.

I tried doing the same and I still have the same issue.

Any insight on what could be causing this?

Dear all,

thanks so much for sharing all this information. It was interesting, unfortunately hasn't been enough for me to solve my problem yet. I have a Samsung 920NW plugged on my Dell laptop (with a 945GM).

I tried a lot of different things, starting with Moninfo (but no EDID info available). Then I tried PowerStrip, but I can't access the "Advanced Timing options" window for my second display. I also tried the driver specially created by Intel to solve this problem. Then I manually tried various DTDs found on this forum, either through the ini file of the driver, either directly in the registry.

None of these worked... Did anyone manage to get the Samsung 920NW run in 1440*900? Or have another idea?

Thanks so much,

ghilus

I'm having a similar problem. I'm using a toshiba A100 satellite and I'm trying to run dual monitor with a Viewsonic 19" display monitor. I know I need a 1440x900 resolution, and strangely enough it allowed me to do this one time, and one time only.

I tried all of the options I personally knew (BIOS update, driver updates, even tried making a custom .INF) and I was wondering if I could get a hand. Thank you!

[Aaron_B_Intel]

I'm on a 945G system and I don't personally have this problem.

First, have you unchecked "Hide modes this monitor cannot display" under Properties | Settings | Advanced | Monitor? I know, it's a dumb one, but I have to ask.

Second, uninstall Powerstrip. If you want to reinstall it later, that's fine, but it can interfere.

Third, make sure you're not trying to display on both monitors at once in "Clone" mode-- you will be limited by the resolution and refresh of the less capable monitor.

Fourth, you're not getting an EDID off the monitor you're trying to work with. That should be our first step. Try enabling it as the "Single Display" in the Intel Graphics Tray, then see if you can get an EDID using the usual methods (Information button, Save to Disk).

Fifth, even if you do get an EDID, it's possible the laptop BIOS has been set up to refuse that particular resolution. Use the .inf hacking method to specify 1438x900, which would not be affected.

There's other stuff to try, but let's do that first.

That EDID is from the laptop screen, it won't help you. Try the stuff I suggested in the previous post and we'll go from there.

Hello!

I can see this has been asked about a million times before in this thread, but I have the same problem as the person in the beginning: I can't get my Benq FP92Wa monitor to work on the resolution 1440x900.

I have a brand new Intel DG31PR motherboard and I'm using the onboard graphics adapter and Win XP. I've updated the BIOS and downloaded the graphics card latest driver for this motherboard.

The basic problem is that Moninfo won't give me any decent info on my monitor, it just gives four Display IDs all marked as [sample].

I've tried making my own INF file in PowerStrip but I can't get the Windows hardware manager to update the driver, it says it the current driver is already the best.

Please help me, I've completely ran out of ideas :-(

[Aaron_B_Intel]

I'd try using the custom resolution tool listed in the sticky at the top of this Forum, specifically using theDTD

AB 22 A0 A0 50 84 1A 30 30 20 36 00 2F BE 10 00 00 18

which works for some 1440x900 monitors.

I am using a LG W1942T which the Native Resolution is at 1440x900 but I could not set it after trying everything.

I am curious why it is showing Native/preferred timing.. 1280x800p at 60Hz while the advertised resolution is at 1440x900.

Any help is appreciated, thanks.

[Aaron_B_Intel]

Good question. The EDID itself does not offer a timing for 1440x900, only for 1280x800, which is probably why it gets listed as "native"-- it's the only one listed. It's possible your monitor can accept 1440x900-- you'd have to search for a modeline or similar timings information from someone who has gotten it working at 1440x900.

But max. res. for my monitor is 1024x768! :-(

I tryed few numbers in DTD and write to registry, but no results.

Can somebody help me?

Hello I am tryng to get a dell Monitor to work and have tried a few combos of Intel drivers and Monitor drivers but no joy on getting the native 1600*900 resolution. Could someone help me please? I am a middle weight PC user but not advanced like some of you guys, so please be gentle with me :)
