these are the intel graphic driver windows in which i can change the settings.

@ Rik
thanks, i will give it a try later on. i mean it's not so bad, cause i can change the resolution with the intel tool as well, but i would have loved to work with poerwstrip.


Is it really 50Hz???

I couldn't find anywhere info about Intel and option for 50Hz.

Which connection are you using and which driver?

Thanx!

Can you tell me which projector are you using?

Perhaps the projector provides the driver with EDID data that includes 50Hz

I am having a similar problem.

I have a Toshiba A100 Satellite laptop (manufactured May 2006).  The graphics card is a Mobile Intel 945GM Express Chipset. I recently bought a Dell E228WFP monitor (22" widescreen) which has an "optimal" resolution of 1680 x 1050.

I cannot get my resolution settings to match that required by the monitor (i.e. 1680x1050 is not an option I can select). The highest setting possible is 2048 x 1536 but the highest that works with this monitor (and what I'm using now) is 1280 x 1024. But things are a little distorted (little too short and wide).

I updated the graphics driver for the Intel card and spent much of the day on the phone with Dell and Toshiba. I tried MultiRes. Nothing has worked. The advice about updating the BIOS sounds good but when I read this from Toshiba, I was scared to try it on my own since I know a bit about computers but I'm not that savvy.

I really want to keep this monitor (got a sweet deal on it). Help.

Thank you TniX51427!

I use Dell D620 with intel 945GM express. I was previously able to set external monitor (Dell P991) upto only 1024*768@60MHz. I had spent many hours and many combination of setting before, but could not get it success.

After I installed A07 BIOS and changed "Primary Display" to "Onboard  Card". Firstly, the setting couldnot be set. It remain showing the same. I tried to re-boot serveral times but didn't effect to them. Accidently, I took notebook to other place, unplug the monitor, reboot and works. Then I took back to my desk and plug monitor cable while my notebook is still turn on. The display setup shows my many new configuration. Thanks again to everyone here giving me many knowlege and idea.

I have tried every possible combination too and, in a couple of instances, managed to get 1680x1050 resolution on my external display (Viewsonic VX2235wm). However this has been completely random. I was wondering if people can explain in more detail the steps required to enable that resolution. It is getting very frustrating as i read some of the proposed solution and none of them have been completely successful. As of this post i have the latest Mobile Intel 945gm graphics card and chipset drivers. Any help would be greatly appreciated.

****************************
*   I FOUND A SOLUTION!!!!!!     *
****************************

I too have a Dell Latitude D620 laptop which has a 945GM express
chipset.  And I too have developed a HUGE lump on my forehead from
banging my head against the walls of my house while trying to get
resolutions larger than the limiting 1024x760(or whatever it was!)

----------------------
I did TWO THINGS
----------------------

1. Downloaded and installed the latest 945GM driver from
   support.dell.com

2. I updated the BIOS on the D620 from the version it came with, A04,
    to A08. The BIOS update can be downloaded from the support.dell.com
    site.

And WHALA! I get crazy resolution now!

Enjoy!!

I agree with JRFERNAN. The bios A08 give me more stable setting of resolution. With A07, sometime resolution I wanted were disappear, but it doesn't happen on A08.

Thanks again.

I have tried all the recommended solutions to this problem and I just couldn't get anything to work.  I had the same problem where the monitor would default to 1024x768 (1280x1024 native resolution).  After about an hour of pulling my hair out, reinstalling the drivers, trying the intel ones (which didn't work on the dell), forcing the resolution (which gave me a "virtual resolution" where the display would slide across the new resolution), upgrading the bios (to A17) didn't do much on my display, under video i was limited to brightness settings and expansion.  Not sure if its just my model or if i hit the wrong button on the bios (F2).

This is what finally worked for me, might want to try it if you are an unlucky owner of the Inspiron with the 945gm Wink

I downloaded the older drivers for the 945GM from dell's own web site:
http://search.dell.com/results.aspx?s=gen&c=us&l=en&cs=&k=945GM&cat=sup

I haven't played around to find out which version intel screwed up on, so I went as far back as the rabbit hole would go: V6.14.10.4431 (from 1/18/2006).

I am guessing that the 4446 drivers work as well, however I have not tested these.  My previous drivers were 4814 which gave me a migraine trying to get the second screen to work properly.

I hope this helps you guys out.

I have been to many forums including dell and I haven't found a solution to some of the similar problems you guys are facing.  I think I have completely exhausted all my resources.  

I have a dell e1405 with Intel 945 Express Chipset Family onboard video card.  I have updated my drivers from A01 to A10 and still no use.  I have also updated my latest video drivers from the intel website.  

Now my problem is that i get nothing higher than 1024 x 768 resolution, but when I plug in my 19'' lcd monitor i get the 1280?1024 available and everything works fine.  I know my video card can support the 1600 x 1050 because when i first plugged it in, i actually got the optimal resolution.  

I have even tried tweaking the intel drivers to manual output the resolution, but I don't think I really understood what was going on.  Please help if you can!

thanks monk.

4446 worked for my E1405.  This driver crap blows. Why can't they get this shit right?

he trick is that you HAVE to add a mode line to your monitor section. In my case, I added it based on this output from xorg.log:

II) I810(0): Supported additional Video Mode:
(II) I810(0): clock: 119.0 MHz Image Size: 474 x 296 mm
(II) I810(0): h_active: 1680 h_sync: 1728 h_sync_end 1760 h_blank_end 1840 h_border: 0
(II) I810(0): v_active: 1050 v_sync: 1053 v_sync_end 1059 v_blanking: 1080 v_border: 0
(II) I810(0): Ranges: V min: 56 V max: 75 Hz, H min: 30 H max: 81 kHz, PixClock max 140 MHz

Apparently, although it's reported by X, X doesn't know how to automatically apply this; I had to modify my Monitor section to read:

Section "Monitor"
Identifier "SyncMaster"
DisplaySize 474 296
HorizSync 30.0 - 81.0
VertRefresh 56.0 - 75.0
Modeline "1680x1050" 119.0 1680 1728 1760 1840 1050 1053 1059 1080
Option "DPMS"
EndSection

In addition to running the 915resolution hack; if I don't do both of these things, I don't get the correct output.

Also - if you're following along at home - DO NOT blindly cut and paste that mode line! Find the "Supported additional video mode" section in your xorg.log, and get the correct numbers from there! If you give the driver an invalid modeline, you WILL destroy your monitor.

tipped me off to replacing the 1600x1200 mode line in the video BIOS rather than just selecting one at random; although the 915resolution documentation doesn't indicate that it matters, it appears to, at least for my card.
