Lenovo IdeaPad S10-3T - Increase DPI And Enable New Resolutions

Increase DPI

Windows is NOT the most touch friendly operating system.  Text, buttons, and windows are not always easy to access.  There is a way to improve the touch friendliness by adjusting the Dots Per Inch (DPI).  When you increase the DPI text, buttons, and windows will become larger.

How to change the DPI:
  • Hit Win key and type "dpi"
  • Select the "Make text and other items larger or smaller"
  • Select the "Medium -125%" option.
  • Click "Apply" button.

The system may make you "log off" Windows, when you log back in the DPI will have increased, and be a little more touch friendly.  If you don't like the new DPI size you can always go back and change the settings.

If you need a higher resolution continue reading on the next section.

Enable New Resolutions

The S10-3T has a resolution of 1024 x 600, which may be small for some programs. There is a way of changing a registry to increase the resolution up to 1152 x 864.

Before you change this registry I strongly recommend creating a "System Restore Point because there have been a few complaints about this mod. Although I never had problems with it.

How to edit the registry to get new screen resolutions:
  • Hit Win key and type "regedit.exe"
  • Go to 
    • HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4D36E968-E325-11CE-BFC1-08002BE10318}\0000
  • Find "Display1_DownScalingSupported" and open it.
  • Change the value to 1
  • Close the registry and restart your system.

Once the system goes back in to Windows you will have brand new resolutions.

Landscape Resolutions:
  • 1152 x 864
  • 1024 x 768
  • 1024 x 600 (default)
  • 800 x 600

Portrait Resolutions:
  • 864 x 1154
  • 768 x 1024
  • 600 x 1024 (default)
  • 600 x 800

How to change the resolution:
  • Right click on the desktop and selecting "Screen Resolution"
  • Change them via the "Resolution" combo box.
  • Click "Apply" and "OK" buttons.

When you increase the resolution your system can display more stuff, however the text, buttons, and window frame will get smaller. You may need to adjust the DPI to make Windows a bit more touch friendly. The screen resolution modification also will make the system work harder because it needs to render more things on screen.

Higher Resolution + Increased DPI



  1. Was able to use new resolutions to get the new Windows 8 Consumer Preview working well enough on the S10-3T. Blogged about the process here: http://www.richonsoftware.com/post/2012/03/30/Windows-8-Consumer-Preview-on-Lenovo-S10-3T.aspx Thanks Jesse!

    1. I am glad the post was useful. By the way your article is fantastic!

  2. Thank you Rich and Jesse. It was very useful and my s10-3t has a new face now..!

  3. HKEY_LOCAL_MACHINE \ SYSTEM \ ControlSet001 \
    Control \ Class \ равным {4D36E968-E325-11CE-BFC1-08002BE10318} \ 0000

    а у меня не 0000 а 0001

  4. it dies not work on win 8 release version...regkey is not , present under 000 class...just under 001

  5. Is this S10-3t works with default resolution with brand new realesed Windows 8.1 ?
    Is touch screen working on Windows 8.1 update?
    Are All other drivers working with Windows 8.1?
    Are the Metro apps and Windows Store open on default resolution 1024 x 600 on Windows 8.1 ?

  6. a) No. The screen resolution has to be changed via regkey change.
    b) That is the problem. After the past fey days I was not able to get the touch function started. I changed the resolution and that seems to be fine, but the screen is - all of a sudden - not able for stick or finger/touch input. I think that it is the graphics driver (intel 3150). But it is working on Windows 8.0?
    c) yep.
    d) nope.
    Does anybody know the solution for the touch-problem?

    1. Working! Win 8.1 works an my Lenovo S10-3T.
      Screen resolution changed via regedit.
      Important: For activating touch you might have to deinstall graphics driver/software. After a restart just let Windows do a driver reinstall. The same driver is online - but with touch!
      Good luck!

  7. Could you post a link or name the graphics driver that re-enabled touch?

  8. Hi Jesse, please help, why my Lenovo S10-3T touch screen not working after updated to Windows 8.1? Thank you.

    1. Maybe because the S10-3T was not designed for Windows 8. Someone with experience might be able to guide you on how to resolve the issue. Check http://haryoktav.wordpress.com/2013/10/04/windows-8-1/

      or google search "S10-3T and Windows 8"

  9. Please help me it worked for but after I changed the O S again I can't acces the metro app on my Windows 8
