It really depends.
Thumb drives are primarily meant to be plugged into a computer and viewed on there.
There are some TVs that have USB drives on them, so give the possibility of playing your thumb drive from that. However, we are not able to guarantee that the thumb drive will work on your TV, as different models have varying requirements that may not be compatible with the specifics of the thumb drive we use.
If you are wanting to watch your precious memories on your TV, we would recommend getting the DVD option as well! Those go directly in your DVD player and work perfectly on the big screen.
