Bug ID: 3291648

The "Maintain Aspect Ratio" is no function on Win 7

NT-Miniport

Windows* 7

Intel® Atom™ N400 Series

Root Cause:

When we select maintain aspect scaling, then driver is properly giving the scaling option and also CUI is sending right scaling option to OS to set display settings. But OS is not giving a commit call. OS is driving Maintain aspect scaling and is thinking there is no change in settings and so not driving the change display settings.

Fix:

PNV graphics driver for Win7 is WDDM 1.0 architecture, so driver doesn’t understands MAR [OS limitation due to lack of CCD support], so a workaround has been implemented in the driver which fixes this issue.

Bug ID: 3176808

SoftBIOS

Windows* 7
Windows* 7 64

Intel® Atom™ D400 and D500 Series
Intel® Atom™ N400 Series

Root Cause:

This is because with latest Win7 build (7600) OS is pruning this mode. Driver is adding this mode in CRT modelist and reporting to OS. But once it is applied, OS does not allow it to set this mode.

Fix:

CUI was modified to be in sync when Hide Mode box is checked.

NT-Miniport

Windows* 7
Windows* 7 64

Intel® Atom™ D400 and D500 Series
Intel® Atom™ N400 Series

Root Cause: 

In the driver, we have a check for Native resolution of the panel (Mode in EDID), which causes this function call to fail for to-be downscaled modes.

Fix:

Whenever call comes for modes greater than Native, driver will handle it appropriately if Downscaler is enabled.
