  • Hi,

    Based on my experience, this kind of issue can be related to the display driver or dirty RAM. Please try to reinstall the latest version display driver. Moreover, in some cases this can be caused by RAM, you can send the laptop to computer technical to test the RAM.

  • Hi!

    at the time I wrote this message there was just an older driver dated to 2009/10/15... Today I see that there is newer version so I will try to install it and I will send my experience with it. Thx form notify me...

    Edit: I have downgraded to older version - the same result. I have upgraded video driver to the latest version - same result. I have cleaned up my laptop - the same result. It seems like that the problem is in the graphics driver - because - using standard video driver the blurry problem disapeared.... very strange....

    Edit: Switching off Aero Peek solved my problem... but still.... Definitely it is graphics card driver problem....

  • Did this issue occur with the previous Opearating System? If not, I recommend you to try to install the graphic driver in Windows Compatibility mode to see how it behaviors. If the issue persists, please involve hardware vendor for help as well.

  • Hello,

    I'm wondering if you found a solution to this problem with the blurry desktop/icons?  My screen looks just like the one you uploaded!!  I just upgraded form Vista to Windows 7 and that's when this problem started.  I changed my bios with VT-d enabled and disabled with no change either way.

    So - by that time I use disable VT-d feature and my Windows is working properly. Unfortunetaly - I do not have further information about this issue. I searched over internet for newer graphics driver (Intel chipset) but nothing new was released for my confugration (Dell Latitude E4200,...)... How did you made an update? Clean install or just a upgrade feature?

  • I just ran into this problem with an Optiplex 380 with a Dell 19" LCD Monitor. I solved it by upping the refresh rate on the monitor from 60 Mhz to 75 Mhz.
