No it's not "weird", it's based on overwhelmingly common usage patters. Proportionally speaking, very few people use their PC with a TV vs on a desk with a monitor, and very few people use a console on a desk with a monitor vs with a TV.It's weird that people have this idea that a console must be in the living room connected to a TV, and a PC must be on a desk connected to a monitor... there's a lot of cross-over these days. People using their PC with a TV; people using a console with a monitor. Etc, etc.
It's not rocket science.
