Unable to view a 1920x1080 second monitor with my Toshiba Portege m400.

[ Edited ]

I am unable to use my new monitor at work.   The monitor is an Acer h233h 23" monitor with native 1920x1080 resolution. 

The chipset is the Intel 945GM Exprss, with the Intel GMA 950 graphics card.  The driver is version 7.14.10.1217

 

Initially the monitor was seen as a Generic PNP Monitor, and the maximum resolution allowed was 1400x1050.

I installed the Acer h233h monitor driver, and the maximum resolution that is offered continues to be 1400x1050.

 

At home, I am able to extend the desktop onto a Samsung 21.5" 226BW monitor at 1680x1050 resoultion.

 

Can the graphics card power the larger 1920x1080 resolution?

Could the monitor driver be the problem?

 

Any help with this problem would be great.

thanks.

Re: Unable to view a 1920x1080 second monitor with my Toshiba Portege m400.

Have the same problem with m405-s8003.

 

I can set 1400x1050, 1440x900, 1600x1200, 1680x1050, 1920x1200, 1920x1440, 2048x1536. But I can't set the native resolution of my ViewSonic VA2413wm - 1920x1080 :smileysad:

 

BIOS version is 3.80 (latest available), chipset is 945GM, video driver version is 6.14.10.4926 (latest available on Intel). Operation system is Win XP SP3 Tablet PC Edition with all available updates.

 

 Can any body suggest something?

 

Thank you.

I too have the same issue with my M105-3041 laptop. I updated 945GM driver from Intel website, and it still cannot go to 1920x1080. All other laptops I have at home works fine and displays 1920x1080 with this new monitor I got.

 

Any solution? Does this intel chipset capable of displaying 1920x1080?

Thanks for the suggestion. The page you referred is describing the issue I ran into. I updated both BISO (from Toshiba website) and Intel driver (intel website), and still not able to display 1920x1080.

After hours of research I found the SOLUTION.

Toshiba blocked the resolution 1920x1080 in their outdated video bios. They blocked exactly THIS resolution.

So you can run with 1918x1080 which shouldnt be a recognizable difference.

 

The whole procedure is described over here:

 

http://www.avsforum.com/avs-vb/showthread.php?t=947830&page=1

 

Download the program DTDCalculator (Powerstrip wont work) - open it with admin rights and set the resolution to 1918x1080 (probably 1922x1080 doesnt work). Then click to the Hack Registry Folder and Add a resolution (more). When done click on Write in registry. Restart and set the new resolution 1918x1020 through the normal method in Windows. I tested it on Windows 7 and it works. The other users in the community over there tried it with XP and 2k. Works fine too.
