How to enable a 70" IR touch overlay to provide touch on a certain lesser size display?



  • My IR touch overlay size is 70 inch and the display I am using is 43 inch. Since the overlay comes on top of the mirror, and the size of the mirror is 70 inch, is there any way to configure a 70 inch IR overlay to provide touch support only on the 43 inch size display I am using??
    How to fix this problem???



  • Would be nice to know this too…



  • Interesting, I have been looking at buying the correct size overlay for my project. I’ve found larger ones cheaper which is annoying. I’ve been wondering if it’s possible to re-calibrate the overlay to a smaller screen?



  • wondering as well…i have a spare 50" IR frame to use with a 40" lcd tv.



  • @joela85 Hi, wondering if you learned a solution for this? I just managed to get my 42 inch IR Touch Overlay set to portrait on my MM. I have a 32 inch LCD monitor for this project.

    Where can I set or adjust this? Any thoughts?



  • @peemoeller Hi, I never went down this route in the end. It might still be something I might try in the future.
    In the end I found a cheap good quality 24" monitor which was going to be fine for my project.
    I found some tutorials somewhere on calibrating a touch display but hadn’t found anything with about calibrating for a smaller monitor.
    Have you tried experimenting with normal calibration to see if it will calibrate to a smaller display?
    I’d be interested if you find a solution to this as I might well be tempted to try it in the future.
