Why pay for another scaler when you've already got one?



well for me its a certain amount of ignorance, I have just heard about
these upscaling dvd players and thoight they sound cool, if the tv can
do the same job then great I wont have to fork out for a new dvd
player!



think about it this way......

lcd tv resolution (for example) 1366x768

dvd resolution 720x576

so if the tv didnt upscale, you'd have a 720x576 image on your tv surrounded
on all sides by acres of black.

the real thing you gain from the 'upscaling' dvd player is that the
connection between player and tv will be digital - which gives you a
superior result to using RGB scart or component.

BUT - even if you do get an upscaling DVD player, with HDMI, you will still
probably get a better picture by leaving the upscaling switched off and
letting the DVD output 576p, The TV will then upscale to fill its display.

In the example above, imagine that you let your DVD scale the 576p signal up
to 720p. When the TV receives this, it will immediately scale it again to
fit it's 768 line display. Now, your image has been scaled twice, which is
really not a nice thing.

Unfortunately, the sales patter of your average salesman in Comet/Currys/etc
will leave you thinking that an upscaling DVD player gives better pictures.
If they do, ask them how the scaler in the £79 DVD player you're just about
to buy can be better than the one in your £1500 - £2000 TV :-)

How do you know it is "not a nice thing"?

It may be that the algorithms in the TV do a better job of processing a 720p
signal to fit the 768 display, than they do a 576p signal.
It may be, as is the case in one of my HD ready tvs that it doesn't attempt
to scale the 720p signal to fit the 768 display at all, but rather leaves a
narrow border top and bottom.

There's no one answer, it all depends....

Im in the market for a large screen tv and I have made my mind
up that I would like an LCD due to the option to connect my pc

42" Screen
PC connectivity
LCD
built in Freeveiw
HD Ready
Pref Black in colour but Im flexible to a point on this.
Budget is up to about £1500 allthough less would be great!

How about a Toshiba 42WLT66 which can be found for less than 1500 GBP.

I have the same dilemma, although wanting to go to 37" max.

Samsung 32/37R74BDX or Toshiba 37WLT66

Samsung has a higer contrast ratio, which is far better than the Tosh's
BUT
the tosh has 2 HDMI inputs!


The single HDMI input on the Samsung can be fixed by using the an HDMI
switch
box. The lower contrast ratio of the Toshiba can never be fixed.

Is the contrast ratio an import factor. Is the Samsung 5000:1 that much
better than Toshiba's 1200:1. An interest point early was made that this
dynamic contrast ratio produces differing black images. Would a constant
ratio, even of 1300:1 be better given that this would not change?

I've heard from way to many Samsung R74 owners that the 'Dynamic contrast'
setting results in unacceptable display behavior. When they disable this
setting (I think you need to select 'film' to disable it), the panel can't
achieve completely black levels in a dark room, much like any other LCD
panel. So what you need to do is find out if 'Dynamic contrast' is to your
liking (visit any store that sells Samsung R74 and have a hard look). If
you like 'Dynamic contrast', by any means, buy the Samsung.
