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.

I had the same problem with my Lenovo x220. Ended up installing previous version (8.15.10.2769) from http://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles/83d636ww.exe http://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles/83d636ww.exe

Hi,

thanks for confirmation of the issue. FYI I have http://forums.lenovo.com/t5/X-Series-ThinkPad-Laptops/Intel-HD-video-driver-update-forced-antialiasing-problem/m-p/1096325 posted it to the official Lenovo forum as well without any success yet.

I had the same problem with my Lenovo E520 and Lenovo SL510

Thanks. Since other Lenovo HD3000 models are also affected, still no hope to get it fixed other than reverting back to older 8.x driver version ?

There is another report of the issue http://forum.thinkpads.com/viewtopic.php?f=43&t=111111 ThinkPad X220 IPS LCD distortion including very good mockup picture that shows the issue.

On Lenovo SL510 (3 pieces) with x4500HD helped to roll back to the original driver from Lenovo. and all the same thing as you, on my Lenovo E520(2 pieces) one of them with HD3000 and another with HD2000. win7 no difference 32bit/ 64bit

[PVone1]

Do you have any 30 series (T430, E530) to check the issue there ? HD3000 is not the only chip that is affected, weird. Is the issue specific to Lenovo machines or other brands are also affected ? I am wondering how comes there aren't lots of reports of the issue. Maybe majority of customers is not updating the driver ?

Hello Intel,

are you willing to solve / solving this issue, i.e. restore clarity of display as it was with the 8.x drivers?

This is really a pain since all our Laptops need to get stuck on win7 because of that.

Thank you for the information. I will update this thread as soon as I get any details on this lab.

Allan.

[JErns]

Thank you, that would be great.

However, I think also this thread contains respective information to not force one to replicate on the exact machine given in the table.

I could guess the developers would have some clue where this is coming from, since the line is clearly from 8.x to 9.x drivers and not so much bound to HW or OS.

Please bear in mind that I will test Intel® HD Graphics 3000 on Windows® 7 and 8 since you are aware that Windows® 10 does not offer graphics driver support for your graphics controller.

Allan.

[JErns]

Hello,

Thank you!

However, the OS is not so important. For first tryout you can already observe this by just using 8.x vs 9.x in Windows 7.

[Allan_J_Intel1]

Testing results:

Demo: Toshiba Satellite U840

Graphics: Intel® HD Graphics 3000

Windows® 7 64 bit

Windows® 8 64 bit

Graphics Driver version: 4229

After fresh operating system installation, I did not observe blurry images, text, videos, social media.

Can you post graphics driver versions you consider are working or not working for your computer?

Allan.

[JErns]

Hello,

From your description it seems you tested on both os with driver version 4229, so the 9.x version?

The difference is visible between 8.x and 9.x version of the graphics driver. Please also see first post in this thread.

(Win 8 vs win7 is only mentioned because 8.x is only available for win7 and when using win8 you have to use the 9.x driver)

[Mx1]

it seems to be limited to Lenovo thinkpads only. do you have any way to test it on some x220/t420/t520?

I have T520 and the same issue. Look here, you'll find some photos. It's not possible to grab a screenshot of this.

[Allan_J_Intel1]

The closest one I have is the x320 Lenovo system and I do not see this issue there.

Allan.

[JErns]

..but I believe you acknowledge the issue exists, maybe not for the 320 but others, looking at the numerous examples and proof in this thread. Right?

[Mx1]

thsi is 3rd gen Intel. Issue is related only to 2nd gen. Hope you saw my photos in the other thread.

[Allan_J_Intel1]

@smg, you were asking for Lenovo, and that is what I got. As mentioned on post 38 with Intel® HD Graphics 3000. I have not been able to replicate this issue.

No, you can not reproduce it on .30 ThinkPad systems like X230. You need older generation, X220 or T420 laptop.

The importance of the issue has raised with Windows 10 upgrade again. The built-in driver is version is 9.x so the issue is back. Unfortunately the older 8.x driver version does not work with Windows 10. So please either diagnose and fix the issue with 9.x driver family or support installation of the 8.x driver on Windows 10.

Thanks
