Jagged Lines


Usually, when drawn lines look jagged or jittery, your SMART Board interactive whiteboard has a grounding issue. This issue can be caused by an outlet or powerstrip. We resolved this issue by chaning outlets after observing the "no ground" light illuminated on a powerstrip. Once, we switched outlets the light turned off and the jagged lines went away.

The symptom can have multiple causes, but all push the SMART Board interactive whiteboard’s electrical characteristics outside the controller module’s design specifications.

You can test for this by removing the SMART Board interactive whiteboard from its mounted position, and propping it up on a wooden surface (such as a table). Then try drawing on the whiteboard.

Please note that your SMART product is no longer under warranty with an expiration date of 12-9-12

We can provide you with some general hardware recommendations. We can also assist with you any software issues for supported versions of our software. 


To troubleshoot your orientation issues, please first delete old Orientation settings from the Windows Registry, which can sometimes contribute to orientation loss. You will need administrative privileges to complete this task.


To do this, please first stop the SMART Board service in the Diagnostics menu from:


Start All Programs > SMART Technologies > SMART Tools > SMART Settings > About Software and Product Support > Tools > Diagnostics >Service > Stop


(On Windows 8, you can press “Windows key” and “q” to search for “SMART Settings”, then open it from the search results.)


Once the SMART Board Service has been stopped, you’ll need to open the Windows Registry:


Press the “Windows key” and “R” on your keyboard to open a text (dialogue) box. Type “regedit” (without quotations) then click on “OK”.


**Important Note:

Be careful modifying the Windows Registry. If you modify it incorrectly, you could possibly damage your operating system. Back up the Registry before you make any changes, and if need be, have your network administrator assist you.


Once the Windows Registry editor is open, back up your Registry by highlighting “My Computer” in the Windows Registry editor > click File > Export. A window will appear giving you the option to save your Registry. Please save it to a location you can access at a later time if necessary. 


Once you’ve created the back up, you can begin making changes. The exact location in your Windows Registry depends if Windows is 64-bit or 32-bit. If you are unsure, check both locations in the following steps.


Please navigate to this location:


Windows 32-bit:

HKEY_LOCAL_MACHINE\Software\SMART Technologies\SMART Board Drivers


Windows 64-bit:

HKEY_LOCAL_MACHINE\Software\Wow6432Node\SMART Technologies\SMART Board Drivers


Delete any key entries that have the word ‘Board’, for example “Board1” or “Board2”.


Please also check the following location for Board entries, and if found, please delete them:


Windows 32-bit:

HKEY_LOCAL_MACHINE\Software\ SMART Technologies Inc.\SMART Board Software


Windows 64-bit:

HKEY_LOCAL_MACHINE\Software\Wow6432Node\ SMART Technologies Inc.\SMART Board Software 


Once you have removed each “Board” entry, please close the registry and re-start the SMART Board Service from: SMART Settings > About Software and Product Support > Tools > Diagnostics > Service > Start.


Following the above, re-orient the SMART Board interactive whiteboard with a 9 point orientation.


If the issue persists, would you be able to swap the computer with a known working computer from another SMART Board interactive whiteboard set up?


If the issue persists past the computer swap, there is one last step in narrowing down the point of failure. The system controller (SC9 or SC12) is located on the lower right hand side of the product, and is where the USB and I2C cables connect. Swapping this part out will narrow the point of failure to either the controller or the SMART Board interactive whiteboard itself.
