Here's an example asking perplexity something I've already researched a lot. I asked what's the best PC monitor for work. It cited several sites including Rtings and Forbes. It then told me the best was a Dell monitor based on the Forbes site. Rtings is definitely the better site for monitor reviews and didn't even rank that monitor as one of the best. I then asked Perplexity, what's the best website for pc monitor reviews. It responded Rtings was the best, listed a few others, and didn't even mention Forbes.
