Can you tell the difference in 1080p 120Hz?

For a tv < 50"?

I am looking to get a 40" LCD. Based on the armoire it is going in, I cannot get anything bigger than 40".

For what I can tell, I basically have to get a 1080p. Not too many 720p in that size out there. But could I even tell the difference on a tv 40"? For blu ray since 1080p is not broadcast yet.

What about 60Hz vs. 120Hz? That does appear to be something I have to determine.
 
Check out this month's Consumer Reports. They tested HDTVs again and this time tested blur at 60, 120, and 240 Hz. The 240 Hz sets were almost as good as a regular CRT set and the 120 Hz sets were better than 60Hz. There are several good choices so it's probably best if you just check out their report.
 
With an LCD the refresh rate is more important than 1080p, especially if you watch a lot of sports...
 
If you sit pretty close to the TV then the 1080p would be good to have, if you are more than about 10 feet you probably wouldnt be able to tell between a 1080p source and a 720.
 
I haven't done a ton of research on this since I bought my TV 3 years ago, but at that time the issue with LCDs was that fast motion (like sports, action movies, etc) would appear to 'blur' more than on a plasma. I'm of the belief that a faster refresh rate helps combat/eliminate this, plus over the past 3 years I'm assuming that the technology has improved to lessen this issue anyway (kind of like burn-in with plasmas)...you might send a PM to hlaustin...
 
Throwing in my 2 cents...I think 1080p matters when > 50" OR if you're sitting awfully close to the screen. As far as 120 Hz goes, its nice to have since it is the only refresh rate that is a multiple of 24, 30, and 60 which are all of the refresh rates for anything you'll buy. This allows your tv to not have to "guess" what the picture will be or do a 2:3 frame set.

We bough a 61" that has 1080p and 120 Hz. I'm sure that we could do without the 120 Hz but the price difference wasn't that much and I'd rather spend the extra cash to have a tv that will support this stuff well into the future.
 
Related question:
At what rate are signals sent to the TV from cable boxes, satellite boxes, DVD/Blu Ray players and other input devices?

If the refresh rate of the TV is greater than the incoming signal, how do you benefit from the higher refresh rate? Interpolation schemes?
 
i never noticed any blur in my old 32" Sony at 60 Hz, but my buddy bought the same set in a 37" and blur was quite noticeable during sports.

I have a 40" sony with 120Hz now and haven't noticed blurring at all.
 
Yeah refresh rate is important on a LCD if you watch any action. The higher the refresh rate the more smooth the action. Also know that there are starting to be quite a few 240Hz models out now which is supposed to be better than 120Hz.
 
The big reason 120hz is so good, is that your TV can display 24fps signals without having to alter how many refreshes each frame gets, like a 60hz set does.

Here's why:

60/24 = 2.5 = uneven refreshes for each frame.
120/24 = 5 = same number of refreshes for each frame, smoother motion (for 24fps sources)

I think I'm right, if I'm wrong, somebody please correct me...
 
A friend of mine's Dad gets Consumer Reports.. I asked him to look up LCD tvs and he did. He said that apparently CR _loves_ Samsung LCDs.

I ended up getting a 1080p 40" LCD 60Hz Samsung. Paid $750 on it a few weeks ago at Best Buy. It is awesome. I gave my parents my older 30" Samsung CRT HDTV and they like it.

I watched a ton of football on it already and not seen any blurring but basketball season hasn't hit yet.
