Parts Express (a Shack sponsor) has keystone inserts for everyting, including HDMI.
Monoprice also has them.
Home Depot even has some, although I've only seen the hdmi at the larger HD in my area (the smaller one closer to my house does not have as good a selection of keystone -- just speaker, ethernet, and cable tv).
If possible, buy them all at the same location just in case they don't fit. They are supposed to be semi-standard, but I've had some that had to be forced or shaved slightly (usually the locking tab) in order to fit. That being said, I've put the Home Depot Leviton RJ45 inserts into the parts express keystone decora holders with no problems.
Good luck.
