The telly program is set around the same time time as the first two books (collections of short stories) I think, but then they weren't released in chronological order anyway with The last Wish being released 2nd but being set before Sword of Destiny which was released first, then there's 6 novels with the first 5 being in chronological order, the final one was set sometime between the 2 books of short stories and first novel, the three games are chronological and are set after the telly program, if the telly program follows the books then the next series should be based on Blood of Elves which takes place around 2 years after Nilfgaard invades Cintra
