I have an HP AIO touchscreen computer that comes preloaded with win7 pro and works fine. It also has a vga in, so i can plug it in as a secondary monitor on my other computer, but touchscreen doesnt work when i do. I called HP and asked for the touchscreen driver (some touchscreens have special drivers), but they had no clue of anything like that. I thought WiN7 was supposed to come preloaded with it, but if i look for "tablet" settings in my computer, its just not there, even though i see it on my AIO. I dont get it, where is the driver for touch? And will touchscreen still work plugged in as a VGA?
