Thanks all for the comments. Received the TV at 6 pm yesterday. Firstly, the TV could not fit on my elevated stand I used for my 40" TV. So had to opt for a wall bracket. It was a good thing that the delivery guy has spare wall bracket.
Once installed, tested it with Transformers 2 BD. It was superb. Very close to the quality that I saw in the store (Yes, I did compare with the Demo mode and normal viewinh when I was in the store).
Then, I tried Love Actually DVD. Slight drop in picture quality but of course, the DVD was just upscaled by my DVD player. So cant really compare it with BD. BUt still much better than my previous 40" Full HD TV.
Last but not least, tried it with my satellite. I connect my satellite in 2 ways. I know that the picture quality for this will not be the best. And the store did mention this to me as well.
1. Using the RF antenna conncetion - picture was of course not the best. Comparing to my 40" TV, the picture was a bit fuzzy and grainy.
2. Via my Philip DVD recorder (analogue to Philips and HDMI from Philips to TV) - Had to connect like this because of the limited input on the TV. The TV only has 4 HDMI and 1 composite. I use the composite to connect my iPod Dock. Improvement on the picture quality. Less grainy and smoother.
Next I tried the internet. Suuupeerb. I have not purchased the wifi dongle so connected it with cable directly to my router. Youtube is superb. Speed was good. Typing using the remote a little bit difficult but still manageable.
One negative side though, the AnyNet+ on the HDMI ,only works with Samsung product. A bit odd since my 40" was a Samsung as well and worked fine with my Sony BD and DVD player. Read the manual and it did say only works with Samsung products. Well, my BD and DVD players does turn off when I turn off the TV. But if I turn off the BD or DVD player, it does not go to my satellite channel as my previous 40" TV. I still have to switch to the Satellite channel manually.And it also does not automatically switch to the corresponding HDMI input whenevr I turn on my DVD or BD player.
Overall, fully satisfied. Although the first hour, I was starting to develop a headache due to the large screen.
Fully recommend LED TV despite theso called 'wrong' information by Samsung.
