If you can get an HDMI cable to pull to the garage from living room - you better go buy a lottery ticket 😃😃😃. I used to do a lot of wall fishing data wire ect ---
you can get a flex bit at Home Depot and if your good drill down wall in garage to underside run cable under then up to entertainment center - of course you will have to remove belly cover. - this method is a little difficult do to the location of current Jack.
A much easier method would be put a access plate/ hole (4x4 blank plate w wall insert) - under sink cabinet bathroom wall - that way it's hidden under sink cabinet, put access hole close to floor, drill down inside hole, inside wall down through floor -- run cable back to entertainment center for one end and drop a sting with a weight on it from garage outlet down wall to new access point to pull other end of HDMI cable up to new location. Living room could done the Same way cutting a access hole under bed in storage area....
Or even an easier way is to get direct TV with a wireless HDMI receiver
