I have checked the specification sheets but I can't find much of any differences between the 29UC88 and the 29UC88-B. Considering the first named is somewhat cheaper in my area I wonder if I should go with that one. I believe they were both released at the same date.

It does say this:
29UC88: Freesync Yes (DP 48~75Hz) &
29UC88-B: Freesync Yes (DP 40~75Hz)
But it also says this:
29UC88: V-Frequency (DisplayPort) 56~75Hz (FreeSync 40~75Hz) &
29UC88-B: Display Port(V-Frequency) 56 ~ 75Hz (FreeSync 40~75Hz)
