![]() Especially since Duo owners in other threads have had their displays replaced, only to have the issue reoccur. I really hope it's not #3 as I haven't had the unit long and won't exchange it for another and won't bother to send it in for repairs. I had to move my taskbar to the Top of my display so that it doesn't close out the program or browser window that I'm working in and instead just opens the date and time window repeatedly. I haven't been able to reproduce the touchscreen issue in any particular scenario, it just happens randomly and generally doesn't last longer than 10 seconds when it does occur. External mice and keyboards don't solve the issue either (wireless, wired or bluetooth). I also thought the Tap's wireless keyboard/mouse was the issue, but turning it off while the cursor is clicking in the top right of the display doesn't stop it from occuring. I also tried moving it away from electronics in close proximity, including my iPhone, but still no change. However I tested that theory just today by leaving the tablet unplugged during use and I still encountered the issue. The Tap and the Duo do have the same power adapter to my understanding (I'm not using a 3rd party power adapter, I'm using the one Sony provided with the unit). RF interference could be a possiblity, but doubtful. I suppose I could just cover the sensor with tape, but I was hoping to avoid getting tape sticky on the housing of my tablet. However, Device Manager (with hidden devices selected) doesn't list an IR device, nor does Devices and Printers or Vaio Control Panel? There are drivers installed though apparently as it controls our TV fine using Sony's Remote app. #2: I haven't really been able to test the IR sensor theory as I can't figure out where to disable the sensor? It's possible that the sensor could be picking up interference and causing the random touch screen input (does the Duo also have the IR sensor?). But they only have software and drivers for Windows 8 and not 8.1, so that could also be cause for the error during install (compatibility mode did not work). N-Trig's support forum suggests that instances where you recieve that error during install to contact the manufacturer of the unit. A couple of Duo owners did state in that thread that they encountered the same error. But I went to our local Sony store and the listed drivers for their display unit is the same as my config. Mainly because Device Manager and program installs don't list anything labeled "N-Trig". I then thought maybe the last 12/17 BIOS update hosed the N-Trig firmware and the touch input was solely being handled by Windows built-in Pen and Touch. io-duo-11-touchscreen-screen-problems.htmlīut when I run the installer it errors saying that "N-Trig hardware was not detected". ![]() #1 seems the most likely as numerous Duo owners have claimed that the issue was solved by instaling the N-Trig Duo Sense software and drivers. I also ran all Microsoft patches for the Windows 8.1 "borked mouse" issue and still no change.Īfter much troubleshooting and research, I've narrowed it down to the following: ![]() So the issue was probably there prior to upgrading. The random touchscreen issue seemed to arise after the upgrade, but I'll admit that I didn't have the Tap long before upgrading to 8.1. Everything updated fine with no issues or errors during install. When I purchased the Tap last November I updated the drivers and BIOS through Vaio Update, ran all Windows updates and then upgraded from Windows 8 to 8.1. I purchased a Sony Vaio Tap 11 (model number SVT11213CXB) and actually have been experiencing a similar issue with the touchscreen as Duo owners, but with the mouse cursor going to the top right (instead of the left) of the display while in landscape mode and clicking randomly. ![]()
