My understanding of clipping is when the input level to the amp is too high.
Distortion, I would say, is when the amp is delivering more power than the speakers can handle.
I happen to have a Samsung L.C.D. T.V. and agree that the sound quality is poor, obviously in the older C.R.T. tellies there's more room for bigger speakers, plus more room for the sound to resonate behind the speaker.
The sound quality is bearable but occasionally we switch on the amp, only an old JVC thing but it does the job.
I'm happy with the picture quality from the set, no issues from the in-built freeview even though the aerial signal is not the best, and it's connected to the computer (sorry P.C. ... I'm just catching up, this is my first computer since my Commodore 64!) via a 15 meter HDMI cable so I can view HD content such asMILF college girls 12the B.B.C. HD channel.
If your p.c. has a separate graphics card I'd try and update the software via the manufacturers website, any problems I've had when connecting to different displays have been down to the graphic cards software.
