Microsoft Surface Pro was released alongside the Surface Pen, a handy tool that allowed owners of tablets to sketch, and draw on the screen without the need for third-party options. At the time of its release, Microsoft claimed that it was the “fastest in the world.” The latest generation of the Surface Pen is also more pressure sensitive with lower latency. It is, in other words, what most Surface Pro users dreamed of except that it is also affected by an unexpected bug.
Accuracy issues with the Surface Pro Pen are widespread, and as the following user reported, recalibrating the pen does nothing to resolve the issue.
An Example of a User Experience Involving an Intermittent Pen Inaccuracy with the Surface Pro
“I have a brand new pen/surface pro 2017. If my hand is not on the screen, the pen is perfectly accurate, even at an angle. About 50% of the time, if I begin a stroke with my hand already resting on the screen, there is a significant offset of the pen line to the actual tip position. This makes hand-writing nigh impossible. Calibrating is useless, since if I calibrate to correct the offset, then 50% of the time it is now offset in the other direction.”
Microsoft commented on the issue, noting that it was widespread. They also promised to resolve the malfunction as soon as possible.
Pro Tip: Scan your PC for performance issues, junk files, harmful apps, and security threats
that can cause system issues or slow performance.
What Causes Intermittent Pen Inaccuracies with the Surface Pro?
Per Microsoft, the reason that some users report that the Surface Pro Pen is inaccurate is because of an electrical issue. The company also suspects that a design flaw or a bug in the driver software is to blame. In particular, the Surface Pro Pen inaccuracies seem to register when the pen is tilted and has to correct for parallax. The parallax correction is, however, only affected if there is an electrical contact with the screen when inking. Simply said, placing your hands on the screen is what causes the kind of electrical interference that makes the Surface Pro Pen to act weird.
