For the most part those kinds of things come to monitors before they arrive in TVs,
Don't think I've ever seen a monitor with multiples of the same input, never mind the five HDMI inputs my TV has. A monitor is usually assumed to be a dedicated device, which is why we need KVM switches when we want to share them. It seems the monitors in your locale are rather different to those available in NY.
The flatscreen monitor I recently purchased had one HDMI input and one DVI input.
But I fully believe yours has more, Cuddles.
