Calibrating Samsung SUR40 for Microsoft® Surface®

  • Comments 27

I’m glad to see so many people excited to get their Samsung SUR40 for Microsoft Surface (“SUR40”) units delivered. SUR40 is reaching customers in over 20 countries right now, and some of the unboxing videos, like this one, have been really fun to watch. I’ve also seen that a few people have questions about when to use the Calibration Tool found on the desktop. Hopefully I can help clarify those questions:

Calibration instructions are available in the Microsoft Surface 2.0 Administration Guide (located here). One of the most important things to note is that you should always have a proper calibration board when calibrating.

If you try to calibrate without the board, you’ll likely mess up your touch input. If you’re curious like me, your instinct might be to double-click the “Calibration Tool” icon located on the desktop just to see what it does. My recommendation is to leave it alone unless you already have your calibration board and you really need to recalibrate your unit.

The best thing to do if you are experiencing any kind of touch performance issues with your unit is to first run the Environmental Light Optimizer tool (instructions here) and see if there are any light sources that may be causing issues. Samsung also provides a Venue Readiness Guide (found here) that has recommendations on optimal lighting which can also help.

Some customers have noted receiving SUR40 units without calibration boards. The good thing is that most units won’t need to be re-calibrated for at least 1,000 hours; as they come calibrated from the factory. Customers that haven’t yet received calibration boards should be getting them from Samsung in the days ahead – well ahead of most customers ever needing them.



  • Guys, you probably should include some verbage in the calibration tool that says something about the fact that running calibrate without having the calibration board handy will effectively trash the device. It would also be nice if the Samsung SUR40 shipped with said board. Not real good to ship a product that is fairly likely to disable itself when the user does reasonably expected things.

  • Better yet, a way to restore the previous calibration would be nice.  I didn't receive a calibration board either.

    I'm also quite disappointed with the response time of the SUR40/Surface 2 compared to the original Surface, and especially compared to my Samsung Developer Preview tablet running Win8.  I'm afraid that technology is moving so fast that the Surface 2 already feels dated; the first comment I get from usability testing is "my iPad doesn't lag like this".  I can't blame it on WPF either, as the XNA scatterview sample has similar issues--dragged objects trail the user's fingers by as much as a foot sometimes.  Any chance of improvement in touch response from software upgrades in the future?  

  • James,

    Our SUR40 Surface 2 unit did not come with a calibration board. Where can we get one? It the Surface 2 calibration board the same as the Surface 1 calibration board? Can we download a file and print a board out ourselves?



  • Hi James,

    sorry for being another one who brings this issue up, but we just received a Surface 2-table which is very badly calibrated. Touch does not work and we also do not have a calibration board for recalbration. Can you contact me about fixing this issue? At this price, one should really expect to have a calibration board shipped with the table. I hope you can help. Please contact me at:

    Greetings from Dresden University of Technology.

  • Hi we have recieved an SUR40 without a calibration board and accidentally went through the process without it and have now lost calibration.

    Is there a way to restore default calibration?

  • Hi,

    In window 7 mode, the mouse does not response in the normal way, always jumps to one corner of the screen therefore difficult to do any operations. Then somehow it becomes normal. Then  jumps again.

    After restarting, still the same.


    Does this mean  that calibration is needed?

  • the local distributer  provided me the calibration sheet, but still the response is not ok, during presentations the SUR 40 responds to the audions movements   (without physical touch) that causes a miss during the presentation.

  • Hi,

    I don't have any board to calibrate it. And we didn't receive from Samsung any board within the following days.

    I have send an email to Samsung support department to request it.

    Any advice to obtain one?


  • Hi James,

    we have received our SUR40 without a calibration board and accidentally went through the process without it and have now lost calibration.

    Is there a way to restore default calibration?

  • James,  I have noticed here that people were requesting ways to restore the calibration data after a bad calibration/not using a calibration board.  Is there a way to save calibration data following a good calibration and exporting the saved calibration data like you could with Surface V1, or is there a way to restore the factory settings of the calibration?  

  • We received a Surface 2.0 without a calibration board. Like so many here,I calibrated it without the board. Now nothing works!

    Can you help me James.

    My id is

  • our SUR40 also came without a calibration board. Someone try to calibrate it without it an now it is a mess.

    can you help us ?
