Hello,

I have a Wacom Cintiq Companion Hybrid, which can behave as (an almost standard) touchscreen. When I connect it to PC, touch functions are activated by Windows.

Unfortunately Windows seems to do that by random: sometimes main display reacts to touch (input on Cintiq, but response on other display), and sometimes it's right and Cintiq responses correctly.

When I go to 'Tablet Computer Settings' and then for Cintiq selected (in display options):

Configuration->Settings(UAC)->What type of display do you want to indentify->Pen input (translation of path might be not accurate - I use polish Windows)

and I'll choose Cintiq as active display, all is fine (by touching it when prompted). Problem is that I need to do it many times when I am connecting Cintiq to PC (it is annoying). It looks like Windows doesn't store any information about defining Cintiq display as the one with touch abilities. Any help would be awesome. Tested on PC and laptop (home and work) - in both cases problem exists.

Beg You pardon for my rusty english - I don't use it very often.

Hi qb.pl

I found your device is actually an Android tablet with a feature as touchscreen, does it connect to PC by using USB or traditional display output port such as HDMI?

The best suspect is that computer Identify your device as an android device instead of a touch screen if you are using USB port.

As you mentioned if same issue occurs on different Windows 8.1 machines, we suggest your contact device manufacturer for support because similar cases could be found.

Check with manufacturer if there is a driver support for this.

Hi Deason Wu,

Thank you for your reply.

It is indeed Android tablet. It has to be connected by both HDMI (video/audio) and USB (probably drivers, touch functions, storage, etc) ports.

I've contacted with Wacom before posting here, and they've send me to MS.

It looks like Windows recognizes display (HDMI port) as independent device and then touch functionality as another independent device (via USB port). In this case Windows pins touch functions to 'first screen in the row', which in this case is Dell without touch functionality.

When I contacted manufacturer about this, they said, that they cannot control Windows behavior and suggested to contact with MS. :(

Best regards,

qb.

Unfortunately Windows seems to do that by random: sometimes main display reacts to touch (input on Cintiq, but response on other display), and sometimes it's right and Cintiq responses correctly.

Which screen is primary?  On W8DP I found that it would get confused about where Touch was going apparently based on which screen was primary.  E.g. I would tap on my TouchSmart and see signs on my wide-screen monitor that the taps were actually ending up there.  Switching the primary screen to be the TouchSmart fixed that.  In fact, I got so used to having the Tablet as primary that I still do with my Surface Pro.  I think the real problem was probably the Ntrig driver for my TouchSmart but I suppose as a test I should make my wide-screen (non-Touch) monitor primary for a while to see if W8.1.2 still gets into that strange state.

Oh.  I just thought of another possible factor, assuming yours is an Extended display same as mine.  Maybe more important than which screen is primary could be where is the primary?  E.g. on the right or on the left of the non-touch monitor.  In my case I always have my Tablet on the right.

HTH

In work I also have my touch monitor on the right of main. But at home it is under main monitor. So it is not the issue. With primary/secondary theory I'll do some testing and get here after. Maybe it would help..

Edit:

I was hoping that testing would last a little bit longer... :)

Unfortunatelly it is no matter if touch monitor is primary or secondary for this issue. But I am thinking about another theory:

Dell monitor is plugged with DVI port and Cintiq is plugged with HDMI. DVI might be a 'primary' port for Windows, and therefore it gains the priority in getting functionalities (ie. touch functionality). I remember that it was important with multiple monitors, which ports were used for which mo

Hi qb,

It seems to me that they said this device was designed as this way and Windows should change for that.

Your suspect makes sense, this device is not a real touch screen indeed.

I found that for real touch screen this issue also occurs when set up a touchscreen as the non-primary monitor in a dual monitor situation. The reason you're not seeing anyone talking about the touchscreen function is that the touch screen is simply a mouse built into the monitor. The only reason it lines up with your finger is that it's calibrated to do so. If you run multiple monitors with touch screen or run one with and one without neither screen can calibrate properly for both screen areas and the touch mouse is locked to the primary active monitor logical location.

Control Panel/TabletPC/calibration - a dialog pops up, press the settings button, and there you can select which screen the touch works for.

The only way I've seen this done effectively is to use the touchscreen as default primary screen however your device might could not.
