Hi Elliot,
Thanks for your response.
I understand that you have tried all of the possible pen calibrations and none of them seemed to help fix the issue. That's not good. Especially since the pen "jumps" as if it is moved by a magnetic force -- that is not a behavior of a properly functioning pen.
Have you considered trying a refresh?
NOTE: Refreshing Surface reinstalls Windows and keeps your personal files, settings, apps that came installed on your Surface and those that you’ve installed from the Windows Store.
You’ll need to reinstall desktop apps from the websites or from the discs that you used to install those apps. Before you refresh Surface, make sure you have access to product keys and installation files for desktop apps that you want to reinstall (for example, Microsoft Office).
Refresh from within Windows
Step 1: Swipe in from the right edge of the screen, tap Settings.
(If you're using a mouse, point to the upper-right corner of the screen, move the mouse pointer down, click Settings.)
Step 2: Tap or click Change PC settings.
Step 3: Tap or click Update and recovery, and then tap or click Recovery.
Step 4: Under Refresh your PC without affecting your files, tap or click Get started.
Step 5: Tap or click Next, ensure that your Surface is plugged in, and tap or click Refresh.
Surface restarts and the Surface logo displays while the refresh process completes (this can take several minutes).
If this doesn't fix the issues with the pen and screen, your best bet would be to contact **Assisted Support**to get further assistance.
