Since upgrading to Win 10 my Surface 4 Pro has been mad (the mouse pointer just disappears all the time and weird bubbles along the right side of the screen). And the display scrolling at will, or not, and so on.
I managed to set everything as was recommended but to no avail.
The keyboard died ages ago, but it works fairly well, when it wants, with a Bluetooth Apple keyboard. Lacks a few keys but there are go-arounds.
When it goes warm the display starts to flutter.
The tips I've found on the net about how to stop the Surface 4 Pro's behavior, most of them from Microsoft themselves were mostly weird, or worse, like "
You can also try resetting the touchscreen’s calibration. Use Windows Search to search for “Calibrate.” You should then see an option to “Calibrate the screen for pen or touch input,” which you should select. Choose the Reset button and use it if possible. If you cannot select Reset, tap the Yes button to start the re-calibration test."
When I eventually managed (after numerous tries) to get the computer to accept the 'Calibrate' search word and that got me to the calibrate page there was only one option, to calibrate the display's color balance. Sigh!
Other suggestions were to do a total reinstallation, nice if you have another PC to help you (no, I don't have a second PC), and so on.
One guy suggested changing the display, a job easily costing as much as the computer itself, if you don't have the tools needed, the display needed, and the skills needed yourself to do it. And that's for sure not me!
Hyper-V can be the culprit, what the heck is that?!
Then you do this:
If updating your system doesn’t work, people have tried a number of other approaches, with varying degrees of success. One of the more reliable solutions is to disable Hyper-V, a visual feature that may have gotten turned on accidentally. The quickest way to disable it is to go to Command Prompt in the Start menu and paste the following command: “exe /Online /Disable-Feature:Microsoft-Hyper-V“.
My problems started after I upgraded to Win 10, so that's definitely not the route to success!
But now I found the trick that made it a sane, standard-like touchpad. I had been using the recommended screen resolution, but, on a whim, I lowered it to 1856 x 1392 (from the recommended 2736 x 1824) and all problems just flew out the window!
By now it has been on for hours without the slightest problem, so just in case you have a naughty Surface 4 Pro, this might help you, too!
