When connecting the video card to the monitor via HDMI cable, I have to wiggle the case-side connection in the attempt to get the picture. Sometimes it works, sometimes it does not. Other connections (DVI and VGA) give me no trouble.
Now, I've noticed that the HDMI port on this card sits too close to the edge of the case opening and there is a screw holding up the HDMI input on the outside, just below the input. Could it be that, because of the closeness to the edge and the existence of this misplaced (in my opinion) screw, the HDMI cable is not making a succesful connection? Or should I be thinking about changing the card?

It certainly could be that the HDMI cable is not making a good connection. Are you able to remove the screw that is in the way? Is there any flexibility in the card/case that would allow you to re-position?
