Vaio TZ11XN won't display 1920x1200 on new Samsung 24" 2443/BW Monitor

I've just bought a new Samsung 2443 BW monitor for my wife.
I've plugged it into her laptop and the flipping laptop won't display resolutions greater than 1680 x 1050.
The laptop is a Sony Vaio TZ11XN [PCG-4L2M]
I've tried updating my monitor and graphics card drivers to no avail.
The graphics chipset (Intel 945/GMA950) is definately capable of displaying this resolution.
The laptop is running vista business edition.
The Intel driver recognises that the monitor is capable of displaying 1920 x 1200.
I'm starting to think that the Sony laptop BIOS is crippling the display modes available to me.

Help!!!

be aware that that is almost always limited by the drivers the notebook manufacturer provides. You'll have to get modded drivers (usually) to get above 1600x1200.

Also see site of intel:
Static modes for non Plug and Play monitors without an EDID. The set of basic static display modes (at 60Hz and up to 32bpp colors) include 640x480, 800x600, 1024x768, 1280x1024, and 1600x1200.

Thanks for the response.

I've been on the Intel website and tried a couple of different driver updates.  Neither have made any difference.  The laptop still only offers up a maximum resolution of 1680 x 1050.  

The Intel driver seems to be talking to the monitor and the Intel Graphics configuration tool seems to correctly recognise the monitor and its capability to display resolutions up to 1920 x 1200.

If you have any idea where I might get modded drivers that would be helpful.

Thank.

ok I will try to look for modded drivers, but did you also checked your refresh rates? Put them on 60HZ and try to get those resolutions? Or did you already tried that?

Make sure you have your monitor settings configured to extend your desktop onto the second display and not to duplicate the contents. If you have it set to clone the displays, you'll be limited to the highest resolution of the smallest display.

It should work fine without modding drivers...

I'm already configured to extend the desktop onto my external monitor.  The little laptop screens 1366 x 768 resolution isn't the limiting factor.  I've seen another thread on this forum with a Toshiba laptop user who has a laptop with the same Intel graphics chip set who ultimately received a bios update from Toshiba that allowed him to use all the available resolutions.  I'm starting to think that Sony have limited the graphics capability of the machine at the BIOS level in a similar way in which they also disable the virtualisation features of the CPU on some of their machines in the BIOS.  I emailed Sony at the same time I posted this thread... still no response from them.

I have read that one as well. You might try that:
http://support.vaio.sony.ie/downloads/updates/updates.asp?site=voe_en_IE_cons&c=0&s=VGN-TZ&m=3659

all drivers/bios updates/utilities etc. can be found there.

Good luck

Thanks for the link.  I've tried that one.

Sony have got back to me.  They say that the laptop will only support a maximum resolution of 1600 x 1200.  Odd then that I can only get 1680 x 1050 out of the laptop even though my monitor supports 1600 x 1200.  I'll continue to chase them on this until they either issue me with a fix or replace the machine with one that does support 1920 x 1200.

Thanks for your help.
