3D screen quality compared to 2D?

The question remains, though: does the "different" polarisation of a
passive 3D screen affect its 2D performance in any way?

I think it is possible, based on my own comparisons, that the passive 3D
polarizing screen filter degrades the off-axis contrast ratio. But here
I'm comparing an LG 3D panel with a Samsung 2D panel and not with an LG
2D panel with the same IPS matrix, so the results may not be meaningful.
The difference could simply be due to the superior S-PVA matrix of the
Samsung screen.

Apparently, early passive panels have a defect known as the screen door
effect. I haven't seen this myself but will keep looking...

Passive 3D sets have polarising material on the front of the screen.
This shouldn't make any difference when viewing 2D, but I suppose it
just might. Obviously the eye is insensitive to light polarisation,
but nevertheless passive 3D screens have a slightly different
construction so it's something we should consider.

What if you are wearing sunglasses with polarising lenses at the time?
Only a daft lad would wear sunglasses in t'ouse.

If there's nothing coming in on RF, there's no need for an RF tuner.

In my house analogue UHF TV (from the PVR, VCR and satellite Rx) is
fed to eight rooms via a distribution amplifier in the loft.
Therefore analogue reception capability is a requirement for all our
TVs, despite no 'over the air' transmissions here any longer.

If I had to guess I'd say that about a quarter of UK homes have such an
arrangement.

Really? The only multi-room domestic TV installations I've seen have
either one proper aerial feed to the main TV in the living room and
individual table top aerials for all the portable sets in the bedrooms, or
separate Sky feeds to all the rooms that have TV. I've never encountered
anyone who feeds a PVR or VCR to other rooms.

I agree that does seem a bit odd in a domestic environment. I have one
aerial feed into a 4-way distribution amplifier that then feeds 4
televisions around the house, 2 of which have an internal Freeview
decoder, the other 2 having an attached STB that then connect via Scart.
Isn't that the normal way?

I meant an analogue feed to each room, irrespective of the source. If
the sample is Sky subscribers only I'd say the figure is about 80%.

Hi all,

I've been asked by my dad to look for a new telly for him. He's
currently got a very nice 2009/10 Viera 32" with Freesat HD and
standard freeview. What he wants is essentially the same thing, but
with a bigger screen size - 42 or 47". I've got more or less the same
telly as him, but the 2011 version, so we'd ideally be looking at
another Viera set as we've been really happy with them.

Unfortunately, I have run into a couple of issues, which a-

1) That Freesat now seems to be an option on the top of the range sets
only, with Freeview HD being the default.
2) Those sets are almost entirely 3D in nature.

Obviously, we'd like to keep the cost down and being 76 he doesn't
give a hoot for 3D, so that feature is entirely superfluous for him. I
suspect that he's also going to want to keep Freesat instead of just
Freeview HD, as there are channels there that he likes that are not on
the Freeview platform.

What I would appreciate some guidance on is whether there is any
benefit to focussing on the more limited range of 2D sets or whether
to bite the bullet and just get a passive 3D set. Are the 3D sets
still the compromise solution that they used to be or do they now give
a picture as good as a traditional 2D panel?

Thanks!


Sounds like your talking Panasonic?
I have 37" Freesat from them think they did Freesat HD because it
preceded Freeview HD, so I can see Freeview HD now talking over from
Freesat HD built in.
Because of the refusal at first of Panasonic to do upgrades for these TV
sets with Freesat to get BBC I-player and refusal point blank to now add
the ITV player to my particular model I myself will avoid Panasonic in
the future.
Is your TV model bigger than 32"? If it is then in order to keep your
father happy with Freesat an easy solution would be to give him yours.
Regards
David

Look at LG 42 and 47 inch models from last year, 650 and 550, good
picture on sd and brilliant on hd.Try currys and comet, or John Lewis.
