Thread: Touch screen problems

I've got a TM-702L in dash monitor with touch screen. The problems is that the touch screen works perfectly in the middle of the screen but as you get to the edge it hangs back from the point of contact.

Is this repairable, is there some calibration software? I'm sure I've seen some screen shots of people with a touchscreen grid to show it working, is this right and if so where can I get the software or do I just need to buy a new touchscreen panel?

I believe the screen is a lilliput thats been put into the in dash case, it's not motorized and not much different to this one: Monitor
