What to look for in a HD TV???

py2006

Hi guys,

I hope this is the right section for this.

I was wondering what I should be looking for when buying a HD TV. I came across a tv with the following spec:

Huge 40" Samsung LCD panel with anti-reflective coating
Fully HD Ready LCD TV with HDMI interface - no loss of picture or sound
1366 × 768 pixel resolution
Includes 2 HDMI ports
Contrast ratio 1200:1
Brightness: 500cd/m2
HDTV (480i, 480p, 1080i, 720p) with HDCP decoding
Digital audio amplifiers with 2 × 15W speakers
Nicam stereo
Teletext
99 programme memory
3D comb filter
Digital noise reduction
Child lock
Sleep timer
Headphone socket
Remote control - batteries included
FREE tilting wall bracket (±15°)
Dimensions: 1013 × 310 × 735mm (with stand) or 1010 × 125 × 690mm (without stand)
Weight: 25kg (with stand) or 21.3kg (without stand)
Scart lead and RF lead included
Free 3 year warranty typically worth €299.00


Is this a good HDTV??

It needs to be pointed out that that unit is not a Samsung , its a Tevion , there is a world of difference between a Samsung TV and a Tevion.

And before anyone mentions it , it may well use a samsung Module from the factory ( as do Sony ) but there is a huge amount of electronics to be added to this to make a TV. All of them critical to the quality of the final product , such as scalers , interface electronics etc.

There have been similar posts on this issue before , just so as ye know before parting with your cash lads

So whats the difference between 1080i * 720p and 1366 * 768 and which is the best to go for?

That's what I was wondering, I never heard of a samsung LCD yet with 2 HDMI inputs.

1366x 768 is the native resolution of the LCD. Quite capable of showing a 720p (progressive) picture.

1080i (interlaced) again is another resolution of which this LCD cannot display natively but can downgrade to its native resolution.

Interlaced is where every second line is scanned, but in LCDs it needs a deinterlacer. This is why LCDs don't flicker.
Progressive is where the image is displayed line after line. All LCDs and plasmas are progressive.

The Samsung M7 Series now has 2 HDMI ports!!

Is 1080i better than 720P? From what I read no it's not, but I have nothing to back me up on this. As Sparky said it displays every second line at incredible rates, so my understanding is if you pause the TV you will in fact only see 540 lines. But with 720P you will always get 720, its the newer more expensive technology. I have also read that if you are watching slow moving pictures, perhaps Golf, 1080i might be better than 720P, but as soon as things quicken up Progressive is the better option. I gues it also depends on what you are watching, e.g. Sky broadcast in 1080i I think, so you would think that getting a 1080i screen you would see an improvement, but again, the feedback seems to be that nobody can see a difference.

As for the ALDI TV, I see it says its a Samsung screen, and that's obvious cause it looks exactly like the older Samsung screens. I also see it mentions LG, so it could be that they are running the electronics, but I dont know this, and that's the main ingrediant IMO to good LCD's. A bit like comparing video cards in PC's to a degree.

I wonder if it would be a good idea if someone would post what to look out for when buying a tv such as minimum specs what each spec means etc. and maybe a mod could sticky it. Id do it myself but I dont think I know enough about it. Any takers ???

I'd do it, but I'm off out tonight.

YoYo, I would think 1080p would be better over all.

Interlaced was only really intended to save bandwidth, I would say a 1080p data feed would be some size compared to a 1080i feed.

Pausing a 1080i picture would result in you seeing the old picture every odd line.

But seeing as most 1080i material is de-interlaced onto a screen, you wouldn't see it.

Actually wikipedia has some good info.
