How to force the 1600x900 resolution on a 1920x1080 screen?

I want to switch the resolution of my Vaio FW with a 1920x1080 screen to a lower one namely 1600x900.

I remember the first model of FW11 had this as native resolution. However, the drivers for the follow models do not contain this resolution in the list.

Is there a way to enable/add it somehow to the driver?

The videocard is ATI 4650.

P.S. I know that the picture will not be as crisp as with the native resolution. That's not the issue here.

 

Load the updated drivers form this link.
Graphics Drivers & Software
Select thru the options menus -model of card etc.
Unzip the package that downloads - remember where it unpacks to - default is C:ATI
unistall the old version
Go to control panel
Update the driver and browse to new unpacked driver.
Let it load - you'll have several options for screen resolution, altho may have your desired 1600x900. (not available with my 3650m card)

 

Open your CCC, go to Information Center
see the "2D Driver File Path"
then navigate to that folder in regedit
in my case, its HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4D36E968-E325-11CE-BFC1-08002BE10318}\0000
Then on the right side, find "DALNonStandardModesBCD1"
double click it, then enter this number on lowest line
16 00 09 00 00 00 00 60
then click OK, then restart
Then try again to adjust your resolution...

 

Right click on desktop, click on personalize (below), then click on display settings (also below) and you can chose any resolution you want.

 

It worked! Man it worked! I love you!

 

What is CCC? I looked in all the Vaio and vid settings, and don't see anything with an information center.

Thanks!

 

Catalyst Control Center

 

Oh... I have Nvid 330m on mine, no ATI.

It screwy, there are no 16x9 preset resolutions other than 1920x1080.

Thanks!

 

nVidia should be able to create custom resolution under nvidia control panel, try look around....

something like this

 

Mine doesn't have the "manage custom resolutions" choice. I tried monkeying around with the "change flat panel scaling" options with lower non 16x9 res, but nothing looked very good.

Not a big deal. Thanks for the effort!
