We have been asked to supply 3 Intel NUC and 6 x 24" 10 point touch screen using 10mtr HDMI Cables. Connecting 2 screens to each of the 3 Intel NUC. When testing in the workshops we found the touch screen did not work as a touch screen. We found the only way we could get this to function was to connect a USB cable to the monitors, this did work. We have now installed at the customers premises but the customer is now saying he is getting drop outs on screens. Here is what he sent us today. "As a matter of note they appear to be worse when two monitors are attached. With one monitor the problem only happens after a few hours."
We connected two 5mtr extender USB cables to the original supplied USB cable, the HDMI cable is a good quality Gold connector. The HDMI cables are converted from the two outputs on the Intel NUC to a full size HDMU connection.
Any thoughts on why this is happening. We have asked the supplier but seem to be getting no where and they are reacting to slowly with any answer. The monitors are rebadged Samsung screens. We have asked the supply to get a statement from Samsung but they seem reluctant to do his. Would a powered USB hub over come the issue as we believe its a USB power issue.
