Hi,
It’s possible that the power supply unit for the HDLink Pro is faulty so you should speak to your reseller about getting a replacement.
I don’t believe there’s any chance to the DVI/HDMI port behaviour but could you check if running the v2.5 driver and see if there’s a difference with the projector you’re using? BTW, what make/model is the projector?
If the utility application is active, it means that the hardware is detected so the firmware should be installed properly. If the firmware is corrupted, the utility application should not even see HDLink as being connected.
