So, do you need HMDI with ferrit core?. Is it better/worse/uneccessary?.
Is there any compatability issues?. What's it for anyway?.

It's for EMC - ElectroMagnetic Compatibility purposes ; basically it's to minimise possible interference issues.
You may well have seen similar lumps of ferrite on VGA leads, laptop power supply leads etc.
It is impossible to predict whether or not it will be necessary in a given situation - safest to have it unless you're able to borrow one without and check first.

You can always buy ferrite clamps from maplins for a couple of quid each and fix at each end of the cable. Personally I have never found they make the slightest bit of difference but I still use them on digital equipment rather than throw them out. Any way experimenting is half the fun :)
