32" TV 720P or 1080P

We will need another 32' tv for the house. We have an old 32' samsung from many years ago and its 1080p and 120hz. From checking online, i see a 2012 samsung 32' tv where it cost 200 dollars for the 720p one and 250 dollars for the 1080p one. Back few years ago i made sure i got 1080p and 120hz but from what i read unless your tv is 40' or above 720p and 1080p is basically the same thing?

I also read that if you watch sports, then you would notice 720p vs 1080p on a 32' tv?

First of all there is NO broadcast or general cable 1080p. 1080i yes. Sports channels tend to be 720p to avoid the interlace issues for fast action.

Because of the interlace 1080i and 720p take exactly the same channel bandwidth.

But yes there is a decided difference between 720 and 1080 even at 32 inch. When you get down to tablet size I would say little and especially for the added CPU and battery drain.

For that little cost difference I would go for the 1080p set. 1080i capable sets if the still are made are upscaled actually 720p screens.

For the channels that are 1080i you will see the actual higher res with a 1080p set, and for some on demand stuff and Blueray will see actual 1080p

But again OTA or general cable there is no 1080p just some 1080i

FOX and ABC are 720p CBS,NBC and PBS 1080i

Re: 32" TV 720P or 1080P

Unless you plan to watch Blu Ray or stream 1080P content then i would not worry about it

Not exaxtly as a 720p set will only downscale 1080i rather than truly display it as it is a 720p display not 1080. That's why many with 720p/1080i capable sets think there is little difference.

DING DING DING DING DING!

That being said, I bought a 32" 1080p set for a guest room out of principle...

Well again I would disagree.... the 32" 1080p I had before my current 40" from 12+ ft across the room I could tell the difference if it was a 1080i channel...remember may aren't! And 720p set will never show better than that, just downscales the 1080i to the 720p native screen. And many will not even display 1080p just i.
Never really done a survey of cable channels, but OTA only CBS, NBC, and PBS are 1080i and its a noticeable difference over ABC and FOX that maybe for sports intelace issues are full time 720p only. Spectrum wise there is no difference, 720p and 1080i take the same channel bandwidth because of the interlace and splitting the frame into 2 sequential fields.

Really surprised any 720p sets are still made unless they are just leftover/refurbs from several years ago. For a $50 or less difference go for the 1080p.

And you will really see the difference in 1080p on demand and Blue Ray.

Then that was likely the function of the scaler in the set/STB or a poor encoder along the way.

The human eye has limits on what it can resolve. And for the most part, we've exceeded all but what Superman can notice.

As comp said, unless you're sitting 3 feet from the (in this case, 32") display, you're fooling yourself (encoding and scaler issues aside). There are TONS of articles and charts out there to back this up.

Taking this to the next level, 4k, most humans won't be able to see the benefit of a 4k display in their normal sized living rooms.

Gets you started on a high-level.

HDTV is no where near what the human eye can resolve.
720 is about 1MP/f
1080 is about 2MP/f

And again on a true 1080p 32" tv from across the room my aged eyes can easily tell the enchanced detail of a1080i channel.

AGAIN though a 720p 1080i capable set DOWNSCALES the 1080 signal to the 720p screen AND not all HD channels are 1080i

The argument isn't about whether or not a set downscales an image.

It's about whether or not your eyes (read: human eyes) can resolve it.

This article also helps explain the resolution-to-display-size-to-distance equation.

At the end of the day MOST eyeballs will not notice if other factors such as contrast, color saturation/accuracy are accounted for.

OK a whole lot of BS in there.... find me a couple of other and ACTUALLY studied scientifically not anecdotally

And again my far from 20/20 aged eyes (though at least farsighted) from 12 ft away from a 32" TRUE 1080p set not 720p 1080i downscaling capable and and actually 1080i or p channel NOT comparing 720p channels (which is most) on a 720p and 1080p set where of course there will be no difference.

Again sorry but a human eye can clearly see the 100% 1 vs 2MP/f res difference between 720 and true 1080 on a 32" screen at across a small room distance.

Even their conclusion literally states "If you are a videophile with a properly setup viewing room, you should definitely be able to notice the resolution enhancement that 1080p brings." then goes on to say you are a clueless typical consumer droid... likely not. Does NOT mean the difference is not actually there.

People used to think AM radio sounded just fine and could not initially appreciate the difference FM made or justify buying a new radio that ultimately KILLED AM music and made it the land of talk crap it is left to today.

And most out of laziness would say McD and other fast foods are the best breakfasts and coffee too.... MOST ALMOST NEVER means better or best. Just mediocre lowest common denominator.
