Currently the EPIC works with Projected Capacitive Touch screens only. The issue is with the calibration, and the PCAP touchscreens do not require calibration out of the box. We are working on incorporating a calibration method into groov Manage to accommodate the standard resistive screens. Also, be aware, that you could also have display issues when using a converter(HDMI to DVI/VGA). Some have had success, while others have not. For consistency, it is recommended that the display being used have a native HDMI port.
