Troubleshoot LCD Monitor Flicker only on HDMI?

[smangular]

I sold a PowerColor 280x Video Card on ebay... Now the buyer refuses to call the manufacture tech support and is not a native English speaker.

ben-q gl2460hm....resolution 1920 x 1080 ....win 7
asrock fatal1ty with fx8350 ,,psu 1000watt corsair. Updated drivers.

The LCD connected with the HDMI cable flickers, but DVI/DP work fine. Any suggestions?

Have he tried the other GPU video output ports to see if the monitor flickers using other types of cable? - I am assuming he is using a PC Monitor and not a TV

Yes, Correct he has the flicker using HDMI only connected to the BenQ Computer Monitor. He also reports it flickers connected to his Vizio TV.

DP/DVI works fine. It happens connecting only one LCD Monitor to HDMI or all three connected to various port (still just HDMI flickers).

Is that a card defect or a configuration issue?

Has he tried with multiple HDMI cables?

What sort of flicker?

Good point will try to push him to try another HDMI cable (reported it was brand new).
Asked him about how often and where the flicker occurs.

What type of flickers are common?

The only "flicker" I have ever seen on an HDMI display is when the display goes black, then turns on, then black, etc. In every instance, the cable was at fault - either not connected well or just a bad cable. Bad connectors on the display and the GPU are possible, but not as likely.
