I guess it's down to personal preference whether you like that dynamic
contrast or not. I think it makes some really dark scenes look better if
you are watching in a dark room, but I can notice when the backlight is
changing brightness and it annoys me.

Not really (at least I've never noticed any difference), all TVs will
display a progressive scan picture, it's the electronics that converts from
the interlaced picture to a progressive scan one. Some TVs are capable of
accepting real 24 Hz video data (for watching films), so that might be a
good feature to look for. I guess they are really running at 48 Hz and just
doubling the data, but it is certainly better than running at 50 or 60 Hz
and trying to display 24 Hz data.
Also some newer TVs run at 100Hz or even 200Hz, this *does* make a
difference to fast moving objects. Even if you have a response time of 0 ms
you will still get motion blur on LCDs because of the way they work (the
pixel is always on, not just a burst of light like a CRT). Doubling the
refresh to 100Hz or higher by inserting extra black frames or using some
clever interpolation certainly reduces blurring on fast moving text and
images.

I think you'll find that most (all?) LCDs have a digital receiver built in,
just plug the aerial straight into it - no need for an extra box or scart
cables.

No, sounds like a dodgy TV to me, or maybe some earth-loop problem?

Find somewhere that will let you take it home for a few days and then take
it back and exchange it for a different one. I find that smaller
independent shops seem to be much more up for this than places like Currys.

Makes sense, I imagine the actual display panels cost about the same. Oh
and on that front, watch out for bright pixels! I've not seen this with TVs
yet, but some cheap manufacturers might be trying to shift cheap panels with
bright pixels - make sure the place you buy it from will let you return it
if you find one, once you've found one you will never stop looking at it!
Yeh well that figures. I bought a long DVI->HDMI cable to connect my PC to
the TV for under a tenner. If you look on amazon there are loads to choose
from. HDMI is used to transport digital video and audio information,
anything you buy that can give digital HD output will have this connector
(all bluray players, HD satelite/cable boxes, PS3, some new DVD players
etc).

You put gold on there to stop the copper corroding that is in contact with
the environment. Why do you think the gold will rub off the first time you
use it? It's usually plated thick enough to last at least a few thousand
connection cycles!

Freeview is what your digital box receives and converts to analogue for your
current TV. New TVs do this internally.

It won't look much different if you sit 4 metres away from a 20" TV. But
sit closer to a 40" TV and there will be a huge difference.

For most TVs the pixel response times are well below the display refresh
rate now, so the only way to get less blur is to use higher refresh rates
(eg 100 and 200 Hz) to try and mimic the CRT style of "impulse" drive. THe
problem only gets worse with larger TVs because the pixels are bigger and
you therefore see more blurring.
