Never got round to actually swapping out the uniquely keyed usb3 monitor cable, but that was next. I changed the dvi cable to the other dvi port on the amd graphic card and the touchscreen immediately worked fine. Was on the point of putting down failure to broad hardware incompatibility between custom built PC, monitor and windows 7 and shelving the commmercial project until. There was some noise to that effect on the web.Īt this point, all connected hardware was identified as working properly in device manager but computer / advanced settings reported that no touch screen device was available.
Upgrading amd radeon 5700 graphics card drivers and investigating the differnet card settings thoroughly to see if they have a bearing on monitor config. Swapping out screen for a known working t232hl screen (known to be working on windows 8) Upgrading motherboard bios (gigabyte ud3r) For the benefit of users that have tried almost everything trying to get t232hl to work on windows 7 X64.
