Graphics output from vpcZ12

Hello,
I bought a vpcz12 laptop a while ago, and I'm very happy with it. But I do have a problem I'd like to fix.

I have a large monitor at home (Dell U2711) which takes a native resolution of 2.560 x 1.440. The Z12 does not seem to offer this resolution, but I wonder why the Z12 screen is running at 1920x1080 and at the same time the Z12 can support a second monitor at 1920x1200. Is it not possible to somehow get 2.560 x 1.440 pixels, even by deactivating the laptop screen through software? Must I use some other hardware (i.e ViDock, if those things are still around)?

I have the corresponding docking station, which has a DVI-D connector. But I guess this isn't for "real" DVI-D digital signals but just for converted VGA signals, as it also does not handle the higher resolution.
So HDMI, VGA and DVI-D (on docking station) ports all provide lower res signals that look nice on a monitor with 1920x1200 native resolution, but quite honestly, pretty awful on the Dell monitor (at lower res than 2.560 x 1.440).

the specs:

Product name found under laptop is VPCZ12C5E
(however the order confirmation says VPCZ12V5E, what is the difference?)
Model: PCG-31112M
Display: 33,3 cm LCD, 1920x1080
processor: Intel Core i7-620M
Graphics: NVIDIA GeForce GT 330M 1GB
operating system: Windows 7 Pro.
Ram. 8 GB 1066MHz DDR3-SDRAM
Bios version: INSYDE R3030C3, 30.07.2010
SMBios version 2.4

would appreciate your help!

many thanks,

David

Hi David,

Looking at the Specifiations for the Z12-Series 1920 X 1080 screen, it looks like the maximum external resolution is 2048 X 1536 with the nVidia Graphics.

It is not possible to disable the on-board screen, so it will only support a single external monitor without buying additional hardware.

Screen TypeVAIO Display Premium

Blencogo, thanks!

I wasn't sure if the graphics specs were still accurate - I read on other forums that Sony is very slow in updating graphics drivers, if at all, so I hoped there was a chance. I use 1920x 1200 for an external monitor at work - great resolution, but 2048x1536 does not work on the Dell, and the step down from the optimum supported by the Dell looks really terrible.

So I guess hardware (external graphics solution) is the only way - just that I can't really find a vendor. AMDs AGP (?) isn't anywhere to be found, but maybe I can import from the states.

Thanks for your input!

David

I am rather frustrated to say the least as my old monitor broke down, and I have a VPCZ12Z9E for which I verified the graphical card to be GeForce GT 330M, and on NVIDA's own page, http://www.geforce.com/hardware/notebook-gpus/geforce-gt-330m/specifications, I happily read that it is capable of supporting 2560x1600 as the maximum digital resolution. This is better than the U2711 capable of supporting 2560x1440, so I went out and bought a U2711.

To my enourmous dissappointment it does not work with my wonderful Vaio!!! Can you please explain why it does not work so that a computer scientist is able to understand why we cannot get the full power out of the graphical card the computer is equipped with?

Thanks...

Typo in the max resolution for the GT 300M chip.
