Riiight. That's cute...

Can you typically tell the difference between progressive-scan and
interlaced? (Obviously I've been watching interlaced all my life, and I
don't think I've ever seen progressive-scan - except on computer monitors.)

Actually, normal TV from a digital receiver and then through a SCART cable.
(BTW, do we know why there's so much ghosting on the picture, even from
a DVD? I thought SCART was supposed to be a good way to transport
signals. Similarly, why do I get electric shocks every time I touch our
video equipment?)

Yeah, that's the other thing. Is that TV naff, or does it just need the
settings tweaking?

A lot of the TV descriptions seem to leave confusion as to whether
you're buying a "TV" or a "monitor". Hmm... ;-)

Heh, figures.
So far, I've observed that the very low-price models have almost no
connectors at all, and the expensive ones have lots of them. It's the
only real difference I can see. (Other than trying to interpret the
brightness / contrast / speed ratings.)

Yeah, I think that's probably the best way to get *accurate* data.

would you put gold on a connector? The very first time you use it all
the gold will rub off!)

[I don't know what freeview is either, but apparently some TVs have it
"built-in".]

Yeah. If I was a serious HD nut I might do that. Actually, from what
I've seen, HD doesn't look any different to SD. (Face it, it's only a
slightly higher resolution.) Basically I just want a non-broken TV! ;-)

My sister's boyfriend has a TV the size of a small star system and a
PS3. (And a Wii, actually.) I had a go at playing "CoD4" on it. It
seemed weird seeing such a vast picture all sharply in focus. Seemed a
tad blurry during movement though...
