In 1997 there was the Pure3D graphics card, it was a 3DFX Voodoo 1 that could do TV output. Of course it could only do it on games as it still needed the 2D pass through for VGA output, but it was neat to see the PC doing what consoles could do.

Credit to HDMI, it finally standardized the IO systems that means PC to TV is trivial nowadays.
