TouchSmart IQ506 Touchscreen Problems

[admineric]

Our company recently got a TouchSmart IQ506 with Windows Vista 64bit, and everything was working fine. We did a fresh reformat, got it in the network and ran all the updates and such. As you may, or may not, know, the IQ506 doesn't have a VGA port to setup a second monitor or connect to a projector, so in order to use the TouchSmart mirroring an image to the projector we purchased StarTech's USB 2.0 to VGA Display Adapter. I installed the drivers and got it working and mirroring the image properly, however, now I am having a problem with the touchscreen.

The touchscreen is responding when I touch it, but the pointer is flushed all the way to the right. The mouse follows my stylus up and down with me, but it doesn't come to the left. It is as if the screen is only reading the y-coordinates of where I am touching, and the x-coordinates are stuck all the way to the right.

The touchscreen was working perfectly fine before I installed the graphics card driver, and the software to get the VGA display adapter to work. The mouse and keyboard is working fine, everything is perfect except for this touchscreen problem. I am 99% sure it is a software issue, and I wanted to know if there is a known issue, or if anyone else has had this kind of problem. I'm assuming it is the software for the VGA display adapter, and was wondering if that is the case, what alternatives I can make so the TouchSmart can support a second display without having touchscreen, or any other, problems.

Sorry in advance if there is already a topic on this issue, I went thorugh the forums and didn't find anything about this.

Okay,

so while trying to fix the problem I was having with my touchscreen, I seemed to have caused another problem. Now I know 100% sure that it is a software problem. I downloaded and installed certain softwares from the HP drivers and downloads site for HP TouchSmart IQ506. First, a handful of the software downloads for the touchsmart weren't able to install, and the ones that were able to install (Touch Screen Calibration, Touch Screen Optimizer) are now casuing my touchscreen to not function at all properly. I tried to go to the calibration and calibrate it hoping that maybe it was some kind of resolution error, or something along those lines. But when I try to calibrate it, the calibration screen doesn't even come up. My mouse, and keyboard still function properly, but the touch screen is now unresponsive. I tried to disable and enable the touchscreen along with playing around with different configurations for the touch screen, but still nothing. Does anyone have a solution for this? I'm not sure if it is a problem with the USB 2.0 to VGA display adapter anymore, but any kind of educated opinion will help. Thanks.

It sound like the calibration screen and the touch "focus" has been shifted to the "primary" display - which is the last added display adapter. I don't have the setup to test, but you might be able to fix by selecting the Touch panel as the primary display (maybe). You may be stuck because the USB adapter will always be enumerated as the last device.

Perhaps...

1) Plug in USB adapter to enable display.

2) Go into display options and select Touchscreen as Primary and make sure "extend desktop" is unchecked.

You may also be able to trick the system by going into DM and removing reinstalling the real primary display adapter.

If all fails, you should be able to unplug the USB device and use MS system restore to go back when it was working properly.

Of course, I am saying all this without having the hardware in front ofme. I've played around with mutiple displays enough to know that you get into some funny behaviour when you have two distinct video adapters installed in the system. The best multi-display solution are those driven from one adapter - one video card with an HDMI and a DVI for example.

If you figure this out, please reply back. I'd like to know if it is possible to keep touch while using another adapter.

Thanks RasterBlaster for your comment.

I wanted to try one thing before your steps and I seemed to have fixed the problem.

The problem with it was that the nvidia card driver wasn't cooperating with the startech driver for the VGA display adapter. I uninstalled the nvidia card driver and everything is working and am now able to see on both screens.

I know that I will be lacking some video qualities, but as of now, everything is working and I think thats whats best. I will try to reinstall the Graphics Card driver, but as of now, the problem is fixed. Thanks.

Excellent! Thanks for coming back and letting us know - to the benefit of others.
