I have Lenovo X220 notebook (Core i5, HD 3000), Windows 7 x64 SP1. I can't stand any kind of antialiasing so I use Windows Classic theme and have ClearType disabled in Performance Options.
After video driver update from version 8.15.10.2769 to 9.17.10.2843 (Lenovo specific versions) I noticed the black text on grey background is blurry and some kind of antialiasing (different than the Windows one) was applied after the update. I couldn't find any way to disable it, no such option in Intel Graphics panel. The only way to get rid of it was rollback to old 8 version. Notice I'm talking about Windows desktop, not a 3D games.
Is there any solution for it (at least edit a value in registry) ? I don't want to use older (possibly buggy and vulnerable) version but this kind of forced antialiasing is blocking issue for me. Attached screenshot (poor image quality) shows the difference, it needs a fullscreen view. Notice the forced red "ghosting" on the right edge of black pixels.
More observations. It affects all output on the notebook display, not a text rendering only. For example BMP or PNG image with screenshot of Start menu without antialiased text also looks blurry now. On the other hand digital output to external monitor is not affected (not blurry). It seems as the new driver set some kind of hardware antialiasing (or less sharpness) in the notebook display controller, is it possible ? I've tried all advanced Intel Graphics panel settings and nothing helped.
The change (non-blurry to blurry text) happens in the middle of a new driver installation, even before restart.
Thanks.
