They do make wireless HDMI bridges, like this one:

I have no experience with them. I would just run the coax cable, and use one that is a similar color to the wall/floor, then tack it down very neatly.
Or remove the baseboard and hide the cable behind/under it.
Or see what would be involved in moving the jack.
