Configure desktop resolution higher than display resolution GMA 3150 D525MW

bongo Sep 22, 2011 1:49 AM

i have an atom D525MW running in a remote location, which is accessed using TightVnc.

the display attached locally does only have a low resolution (1024x756), as there is no space to attach a big tft.

nevertheless, i would like to run the D525MW (GMA 3150 graphic unit) at a high display resolution as the software, running there, is optimized for 1600x1200, and i would like to get this resolution when accessing with TightVnc.

from older notebooks, i know that there is (was) a way to run graphic cards at a higher resolution than the display is able to show. the part of the desktop shown then follows the mouse pointer. the monitor then always shows a limited region of the desktop, like a window moved over the desktop.

unfortunately, the driver i got for the D525MW does not seem to allow such a configuration.

how can i solve this? i.e. is there an alternative driver or a utility which allows me to have a 1600x1200 desktop with a 1024x756 display monitor attached?

thanx for your help!

Hi,
The graphics controller drivers will support just about any video modes as long as the monitor’s EDID (Extended Display Identification Data) supports it. I'm just concerned you are using a 1024x756 display monitor in respect to the resolution you are trying to accomplish.

hi
maybe you misunderstand me.
i don't want to show a 1600x1200 resolution on a 1024x756 monitor!
i want to run the display adapter in a way that allows to have a 1600x1200 desktop, which i can see in it's full size using tightvnc.
but as there's only a 1024x756 monitor attached (unfortunately, there's no room there to have a bigger monitor), this locally attached monitor shall only show a section of the desktop.
i know this was possible some time ago (i had this on several notebooks, was probably with win95) but i don't know how to configure.
can this be done using a special display driver or is there any add-on software that allows to do so?
thanx for your help!

Thanks for the extra details!

I confirm for the specific configuration you refer to, you may want to check with the developer of TightVNC. From the part of Intel, the video driver, per se, does not allow such configuration.

What you are wanting is the ability to 'pan' your desktop and although the Intel driver doesn't have this ability built in (unlike an old Matrox card I used to own), there are third party products out there that attempt to perform this function. Whether they work reliably with your hardware to give you what you want is something you'd need to try out for yourself. If you search for desktop panning software, that should set you in the right direction (as well as contacting your software publisher as already suggested by Salem_Intel).

got it!
by simply unchecking the ' hide modes that this monitor cannot display' a higher desktop size can be selected enforcing the display to pan.
so simple, without any addon software!

Be aware that (as already inferred) running a TFT monitor in other than its native (recommended) resolution can (possibly) cause the monitor to fail prematurely so I'd suggest you use this approach with caution.

with this setting, surprisingly the monitor is still running at it's native resolution, just being a window into the much bigger desktop area.
