Mobile 4 Series - Scale Full Screen option no longer works under Scaling or Panel Fit

[idata]

I'm currently running version 8.15.10.2202 of the 4 series GMA drivers (4500MHD) under Windows 7 Home Premium 64bit and I've just noticed that I can't change the screen scaling any more. In the Intel display utility, I can select Scale Full Screen (or Maintain Aspect Ratio for that matter) and click Apply.. but once I click OK and close the utility it has reverted back to Center Image. Similarly, from the Graphics Options > Panel Fit desktop context menu, I can select Scale Full Screen or Maintain Aspect Ratio but when I check the context menu again, it is still set to Center Image.

I know this worked with a previous version of the driver, though unfortunately I don't know which version that was as Win7 has updated the GMA driver a few times since I last would have noticed it. Has anyone else come across this issue before?

If not I'll poke around the registry under Software\Intel\Display and see if I can find a key to force the scaling option..

Just tried 8.15.10.2226 and I still have the same problem. Found the following keys in the registry:

HKEY_CURRENT_USER\Software\Intel\Display\igfxcui\Configurations\ActiveDevices\4096-SEC5441\PrimaryAspectScaling

HKEY_CURRENT_USER\Software\Intel\Display\igfxcui\Configurations\AvailableDevices\4096-SEC5441\PrimaryAspectScaling

However, changing the values of these keys has no immediate effect on the scaling and the registry changes revert to their previous values after rebooting.

All of the above threads seem to describe a similar issue. It seems like the driver gets 'stuck' on a particular scaling option (and which option seems to be random) and you can't change it back, not even in the registry.

Hi,

It seems somthing wrong with the new drivers from intel. I have faced same problem here on my laptop. For testing I've installed the driver from Microsoft Windows Update and now the Panel Fit Scalling is working fine.

Steps:

1. uninstall the driver from device manager also check "delete the driver software for this device" so that it can't install same driver again.

2. restart your computer

3. after restart go to control panel > windows update > check for updates

4. select Important Update > Intel HD Graphics driver and install.
