Mine doesn't have LFC I never notice any frame issues but I am on an RX 580 with an i7-7700k. I have no games that my system can't at least keep in the low 40s.
Confirmed listing error.
LFC can be supported on any monitor with an upper FreeSync range 2X above the minimum. It is enabled automatically at 2.5X. Anything below 2X is apparently a non-starter and mislabeled in the database.
