I am assuming that you are thinking of buying from Amazon.com (US) website. The US TV will have 110V/60Hz and NTSC colour system. You will have to check what is compatible in Nigeria. If I am not mistaken, Nigeria is 220V/50Hz, PAL country. In this case you will have to buy a 220V=>110V step down transformer and a PAL to NTSC converter. Then the TV will work.
