Like a million other folk I have been investigating TV's for some time regarding going through the whole LCD/LED, 100hz, big screen size etc. I am replacing a peach of a TV, a Panasonic 32inch 100hz with in-built 5.1 - but it's ten years old and I decided I had to finally remove the sandstone block and replace it with one of these funky flat screens.
Long story short - picked this TV finally and it is simply jaw-dropping - if you buy it for the right thing.
Type of Viewing
===============
I am predominantly a Standard Def viewer, from a Sky+ box, combined with a huge library of standard def DVD's. I have an LG standard def recordable DVD for capturing mainly movies off the Sky+ planner - or direct.
Distance
========
For myself I discovered that the most important aspect of buying the TV is the screen size. As I expect the TV to do all the upscaling - thereby giving consistency, getting the screen size correct to remove visible artifacts was really important.
I would recommend this TV for someone who sits 12 feet away - yes that's right 12 feet - if you are watching SD inputs. Viewing from the DVD you can go to 9 feet, viewing from Sky or Freeview then 9-12 feet.
Sound
=====
The set comes with standard sound, and TruSurround HD. Having been used to the 5.1, then the sound without TruSurround is very tinny, and with TruSurround, you could live with, but you would always feel that was what you were doing. I would not downgrade the TV because of this - basically all of the LCD's seem to suffer from this aspect. However there is an analogue L/R channel output that I popped into my old Arcam analogue amp and played through the two standard speakers and bingo - great sound - so the limitation is the speaker output from the TV and not the sound processing.
Now for the overall review.
Colours to die for
==================
I have a Toshiba 32inch Regva with Resolution+ - the 635DB - and this Samsung blows it away with depth of colour. Viewing movies from Standard Def DVD have simply stunning depth of colour and brilliant upscaling - truly best-of-breed. You will sit spellbound watching old movies take on a new lease of life, with detail and clarity that just was not presented before. I cannot stress this enough - truly phenomenal colour depth - no need to get a LED to see the depth of colour - blacks truly are blacks.
Overall upscaling
=================
Again fantastic job done by Samsung. The image processing is spot on. The only weak spot, as always, is fast-moving sport - however the level of detail is still great and easy on the eye. I tried the next model up - the 650 with 100Hz - makes no difference. The 550 with 50Hz displays the same - at least to me. If you run HD sport through it - e.g. Sky Sports HD then the detail is stunning. Watched the Formula 1 yesterday - handled it superbly - lovely crisp clean images on standard BBC1 signal.
Connectivity
============
I have connected all my bits and bobs with SCART - yes good old SCART - to get the above results. No need for HDMI - as I am not doing any fancy digital sound processing - just simply analogue feeds out to standard amp. The set has loads of HDMI and Optical Output for sound, so that when I do eventually move to full 5.1 or 7.1, with HD, then the TV has everything I need.
So in summary - superb and fantastic TV - delivers everything you want and then some. The key is buying the right size to match the type of TV you watch. I suspect the majority of purchasers are like me - built up a large amount of standard definition DVDs, watch a lot of standard definition TV - either Freeview or Sky, and sit about 9-12 feet away - usual size of living room. If that's you - buy this TV - do not waste your money on fancy gimmicky stuff like 100Hz, 200Hz, LEDs - this TV delivers what you need - not what the salesman wants to sell you - and it delivers it a price that is simply astounding.
If in doubt - go to a store - Currys, Richer Sounds etc. - get the salesman to put the Freeview digital channel on, measure the floor distance and stand and look at it for ten minutes. If after that time all you are left feeling is - wow - then buy it, if you are left feeling - picture not quite sharp, little artifacts appear, jaggy lines in sports - just think how you will feel watching it every night for five years. That's what led me to the 37 inch rather than the 40 inch, or even a Phillips 42 inch.
So in summary - pick the right size TV for what you predominantly watch - and if like me thats 9-12 feet with a need for high-quality standard definition - then at this price there is simply no other TV that comes close.
