Hello! I have had my Asus Taichi 31 for about a month, and since I have updated to Windows 8.1, the touch screen has not worked. Only the normal screen works. I’ve tried googling a fix, but I am not very tech savvy at all and have had difficulties finding solutions. Apparently it might have something to do with Windows 8.1 updating Intel to 9.18 or something? I would love some help – but try to explain it in very simple terms please!

How to fix dual screen problems in Windows 8.1 on Asus Taichi

First of all, make sure that you’re running all the latest audio and video drivers related to your specific device, but also that you have done the same to Windows with the Update function. If so, then follow this:

Try the troubleshooter

  1. Run the hardware troubleshooter by pressing the ‘Windows + W’ key on the keyboard and then type troubleshooting in the search box
  2. Now go to hardware and sound and run the Hardware and Devices Troubleshooter
  3. Restart after following the instructions

Tweak the touch screen drivers

  1. Press “Windows Logo” + “X” keys on the keyboard
  2. Now select “Device Manager” from there
  3. Go to “Human Interface Devices” and expand it, look for the Touch Screen device from the device list
  4. After finding it, right click and then select “Uninstall”
  5. If you encounter the “Delete the driver software for this device”, you can go ahead and do that
  6. Follow the instructions and restart
  7. Now go to Device Manager again and then click on the “Scan for hardware changes” button

Now, this should do it. If you know of another working method, don’t hesitate and let us know by leaving your comment in the box from below.

  • And of course nor Microsoft. They make you spend lots of money, then they forget you. Now it’s my time to forget them. Not even a single Euro to them. Nevr again.

  • I’m on the phone with ASUS at the moment. Their tech assistance people are telling me the problem is that Windows 8.1 doesn’t support the back (tablet) screen. They are suggesting a BIOS flash, which would void the warranty on my 5 day old machine. I told them I’m not happy about that, and I’m waiting for a response…. The response is that I can ask the service centre if they will do it under warranty. If not, I can try to revert back to Win 8.0, go without the tablet functionality, or flash the BIOS myself.
