What exactly do you mean by “watching” on the PC?
If you’re talking about blue TV, then you simply have to be aware that blue TV only offers “small screen” resolution via the web browser, i.e. the transmitted bit rate is geared towards small mobile phone screens, which can of course look quite “dim” on a larger PC screen.
If you want to play blue TV in really good quality on your PC screen, you need to connect a TV box to the HDMI input of the PC screen so that you can also utilise the much higher transmission rates of the “big screen” qualities of the blue TV video streams.
PS: Incidentally, there is no connection at all with the subject of fibre optics here, because blue TV never requires a bandwidth of more than approx. 18 Mbit/sec, even in the very highest resolution, which still runs without any problems even on a rather lame copper line. Incidentally, the “small screen” resolution only requires approx. 2 Mbit/sec
