Whether or not the portable drive is readable has to do with if it was formatted a certain way. I know exFAT can be read by PC and Mac, so best to check the user manual to see what format is needs.I always have issues getting a TV because they don't all come with a variety of ways to connect devices anymore. So to find a TV with all the proper AV inputs for my vintage gaming systems is always a pain. I recently got a 55 LG that had it all tho. Before that, i would always buy Samsungs. The other thing is I need USB readers that can read most Portable Drives for the shows and movies I have downloaded.
Also, I am needing more than just 3 HDMI ports. I still use PS3, PS4, now got PS5, Apple TV, and sometimes use TV for extra computer monitor.
