Now, that the Samsung SUR40 for Microsoft Surface ("SUR40") units delivered to coustomer in over 20 countries right now. To help customers, using the Calibration Tool that's located on the desktop -- Microsoft informs that the "Calibration instructions" are available in the Microsoft Surface 2.0 Administration Guide.
"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," explains Microsoft.
Adding, the company notes, "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 and see if there are any light sources that may be causing issues. Samsung also provides a Venue Readiness Guide that has recommendations on optimal lighting which can also help."
The SUR 40 has a 40 inch Gorilla Glass display to prevent damage even when a heavy object is dropped on its surface. Other than the large screen, it also features the AMD Athlon Dual-Core 2.8Ghz and AMD Radeon 6570M and of course Bluetooth, Wi-Fi and WiDi.
