I have been having an interference problem with a short (1.5m) run of HDMI cable between my laptop and screen for quite some time.
My setup is as follows: I live in a university residence and my laptop (Dell XPS 16), screen (Dell 24" 1080x1920) and fridge are in close proximity to one another.
The problem presents itself as follows: For reference it is remarkably similar to HDMI video dropping out but I have learned some more through experimentation.
The dropouts occur when me or my roommate's fridge's thermostat kicks in or out thus leading me to believe there is some problem with the cable. Also, when placing my mobile phone (Blackberry Curve 8250) on the HDMI cable and initiating a data connection it also drops out.
The Cable: $5 Ebay cable that works fine otherwise. I suspect the plastic molds near the ends are fake and do not contain real ferrites.
Here is a picture:
- Is there some way to better shield the cable or otherwise resolve the problem?
- Should I cut open the molds to see if there are ferrites inside?
- Should I buy a new one?
- What should I look for in a new cable to prevent this?
