HD 3000 driver forced subpixel antialising after update to 9.x version

[PVone1]

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.

This issue might happen on older graphics controllers since graphics drivers for Windows® 10 are not available at Intel web site. The support for Windows® 10 is available from 3rd generation graphics and above.

So the built-in driver installed by Windows 10 upgrade on HD 3000 is an "unofficial" Intel driver ?

Thanks.

That one would be an Inbox driver provided by Microsoft*. It might not have all graphics feature your computer requires to run properly because again, the operating system is not supported.

Solution:

1. Download Display driver ("DriverVer=01/10/2012,8.15.10.2622") from intel.com.

https://downloadmirror.intel.com/21415/a08/Win7Vista_64_152254.zip https://downloadmirror.intel.com/21415/a08/Win7Vista_64_152254.zip

2. Unzip and modify "Graphics\igdlh64.inf" as following:

Original:

[Manufacturer]

%Intel% = IntelGfx, NTamd64.5.1, NTamd64.6.0, NTamd64.6.2

[IntelGfx.NTamd64.5.1]

; no install on XP

[IntelGfx.NTamd64.6.2]

; no install on Win8

[IntelGfx.NTamd64.6.0]

Modified:

[Manufacturer]

%Intel% = IntelGfx, NTamd64

[IntelGfx.NTamd64]

3. Install this display driver on Windows 8 or 10 (refer to following link).

Found similar thing on T520 (1920x1080), windows 7 pro x64, very annoying.

Particularly for me to have T60p (ATI 1680x1050), T61p (Nvidia 1920x1200) and X1(HD3000, 1366x768) to compare with.

Black fonts in explorer looks just tinted and not as sharp as in all other models.

Tried latest driver from Lenovo, something 2012. and 9.17.10.3223 06-27-2013

I am expecting to get black to be darker and fonts being sharper.

[new] I downgraded to 8.15.10.2769 05-25-2012, it looks much better and closer to Nvidia display now. Although Lenovo driver log said, upgrading to 9.17.10.2843 has fixed issues including crashing. I will take the risk for now.

Thanks

I have the same problem, but I think its a viewangle problem.

Depending on how i tilt my display it looks "normal" as if using previous driver, does a view angle setting exist in registry?

Just to provide update: I tried: 9.17.10.3347 (05 Dec 2013) from Lenovo: http://support.lenovo.com/en_CA/research/hints-or-tips/detail.page?&DocID=HT063271 http://support.lenovo.com/en_CA/research/hints-or-tips/detail.page?&DocID=HT063271

The blurring edge has been improved at least on my external display. Hard to tell on built-in display. But there definitely has been improvement. So someone had worked on the issue. To give credit.

Thanks,

hi, any news on that? I have the same issue with 9.x driver on win7/8/10. Old 8.x driver is fine on Win7 and only this one is not blurry.
