Display issues. Possible bad USB cable?

Hey guys! I just received my new USB 3.0 UGA in the mail today from Amazon. Installed latest drivers prior to plugging in to computer. Win7 failed to recognize device at all (no acknowledgement of insertion). Flexed the USB3 cable around a bit and was able to get it to recognize, but now have flickering green dots on HDMI monitor display. Dots are not there when using DVI from other video card. I can get the device to fail & return to operation by flexing USB cable part way down. Pretty sure I have a bad cable, possibly more but can’t tell for sure.
