PC não reconhece televisão

Question

Eu tenho uma Sony Bravia tv que eu preciso conectar ao meu computador. Quando tento conectá-lo ao meu laptop, tudo funciona bem. No entanto, quando tento com o meu PC padrão, nem sequer reconhece.

O laptop tem cerca de um ano e tem especificações menores do que o meu PC, então o que estou fazendo errado?

Aqui está uma lista das especificações do meu PC:
