So is it 1080p or 720p?

I just bought myself a LG 32" 720p LCD Model number 32LD350, or so i thought. Best buy advertises it as a 720p but LG's website (before they removed it off of their site) said it is 1080p. The box doesn't list a resolution on it and for every web site I find that says it is 720p I find one that says it is 1080p. My playstation treats it like it is a 1080 too which only adds to my confusion. Any clarity someone can bring to this would be great. Thanks

ThanksThe limited information i can find on the net shows the actual screen resolution for the 32LD350 to be 1366 x 768, and if that's true then the TV is a 768p model (not 720p or 1080p). As such, it will accept 720p, 1080i, and 1080p signals but will scale them to it's native resolution of 768. And at that low of a price, it most likely is not a 1080p set (they tend to be several hundred $$ more than the 768p models).

Does your owner's manual state the actual resolution of the screen in the specs? Does it say 1366 x 768?

Believe it or not the manual doesn't list a single resolution any where in it. Me being a HDTV noob I have to ask, It being an off resolution like that is it better to have my ps3 and such run on 720p, 1080i, or 1080p when on this tv? Thanks for all your help by the way.

Sorry about asking a question for the million and first time. Just ran across this forum on google and just jumped right in.

There have been a lot of debates on the topic, I have both.

The 720p upconverts dvd way better!

A real 720/60 has more than double the frame rate than 1080p.

I seen a real 720p/60 on a 720p set and there was no difference on the 768p set.

At a distance of 11 feet you're not going to see much of a difference, with a 1080 signal.
But a1080 signal still looks better on a 1080p set.

If you have a good 1080p set a 1080i signal will not look much different then a 1080p signal, they are made to paint both fields of 540 on the screen at the same time.

Since there isn't too much of a difference at 11 feet with average sets, I wish all signals were 720/60. I like the 60 FPS. You're seeing 60 different pictures a second rather than 24 SMOOOOTH!!!
I still say 720 looks better on my 720p set than on the 1080p. Even though it's an LCD.

So where does that leave us?

Keep in mind LCD only displays 600p of moving resolution where the 2009 Panny plasmas passed all 1080 lines!

Like comparing a sports car to a cadillac, the 2 signals are great in different ways.

1080/24 2 million pixels 24 frames
720p/60 1 pixels million 60 frames

720p/60 on a 768 set is as smooth as honey.

But a 1080p set has to add 1 million pixels when a 720p channel is on it!

But doubling the pixels does not result in double picture quality because of the limits to the human eye.

But doubling the frame rate is perceptive to the human eye, I read all this, forgot where. But not all 720 signals are 60 frames some are 30.
What I do is DVR all the 720p channels on my Sony, 768p, and the 1080 channels on the 1080p Plasma. Keep the DVR in native and disable the 480i option, so it makes all 480i into 480 progressive.
Watch all standard DVD on the Sony 768 as it upconverts DVDs better.

I hate interlaced signals.
But what are you going to do, we have 3 HD formats.... TOP 2 is 1080p and 720p they are great in their own way.
Again if you have a good de-interlacer like my Plasma, it displays all of 1080i as progressive.
I looked at the 2 signals very closely, 1080i pushes green tint, where 720 pushes brown/tan colors, flesh tones. I don't know why. The bark of the tree looks better in 720p, where the leaves on the tree look better in 1080.
There is more of a difference in Plasma over LCD rather than 720 vs 1080. That is what you should be looking at. That is where I made my mistake, through 5 LCDs sets I now know how much better plasma is than LCD!

1080 or 720........Get both! But make sure it's a plasma!

That was a difficult read. Not sure what all it had do to wording and context though. Hmm. I think 1080p/60 is still 60 as is 720p/60. How are they different again?

Yea you're right I misread the OP,
either way... I'll explain it this way, where are you getting 1080p 60?
Games maybe, getting the frames from two fields of 540 is not real 60 frames, because the 1080i signal pumps at 30 frames.

Blu ray is 24 frames, I don't care if you double triple it, it's still the same frames.

"1080p/60 is essentially the same frame repeated twice every 30th of a second. (Enhanced video frame rate.)
http://hometheater.about.com/od/televisionbasics/qt/1080ivs1080p.htm

The shutter speed is still 30 frames where the shutter speed for ESPN 720 is 60. So you're seeing 60 differerent pictures rather than the 30 twice. When you're box is set to 1080i it is pumping 30 frames, the frame rate from the box is not as fast.

720p/60 are 60 different frames, not the 2 fields of 30 repeated twice.



What station broadcasts at 1080p/60?

What station broadcasts at 1080p/60?720/59.94 is not always 59.94 frames per second. If it is film based it is still only 24 frames per second with a 3:2 pulldown added to it and it could also be cross converted from a 1080i/29.97 signal.

I said that above
"But not all 720 signals are 60 frames some are 30"

But there is a real 60 frames and it's in 720p.
When you're watching Monday night football, that is 720p/60, and the NFL on fox, and if you're box is in 1080i, you're getting half the frames.

This is why I rather watch 720p/60 on a 768 set, a 1080 set has to to add 1 million pixels to the broadcast that are not there.


1080/60... you're seeing the other field of the same frame.
ESPN is thinking of 1080p/60, until that day comes 720p/60 still has a feature 1080p does not have.

So even though a system is 29.97 (30) frames per second it really is 59.94 (60) individual pictures except when shooting 29.97PsF then it's only 29.97 pictures per second. That is why if you still frame a picture and DT is set for frame mode not field there will be jitter in that still frame. So a 1080i/29.97Fps video based show will really have 59.94 pictures in that second.

On a side note I saw part of a soccer game that was shot in 1080p/59.94 and it looked awesome. The way HD should look. But the problem with that is it is double the bandwidth so broadcast would be a real problem.

The box is still at 30 frames, I read every where
"1080p/60 is essentially the same frame repeated twice every 30th of a second. (Enhanced video frame rate.)
http://hometheater.about.com/od/tele...80ivs1080p.htm

"Almost all HDTVs that accept a 1080p input signal directly can accept what is known as 1080p/60. 1080p/60 represents a 1080p signal transferred and displayed at a rate of 60 frames-per-second (30 frames displayed twice per second). This is a standard progressive scan 1920x1080 pixel video signal."

http://hometheater.about.com/od/televisionbasics/qt/1080ppitfall.htm

Different than 60 consecutive frames per second.

And I believe 1080i scaled down to 768 looks better than 720 upscaled as the missing information has to be guessed at which leaves room for errors and artifacts.

Thanks for all your help by the way.It can be subjective so try the various output resolutions and see which one looks best to your eyes on your TV with your content.

FWIW, on my two 768p LCD TVs, one 768p Plasma, and two 1080p Plasma TVs i've found that setting my Tivo HD and SA8300HD to output everything at 1080i Fixed and it makes all the 480p, 720p, and 1080i channels look crisper and more detailed. If i set them to output all the same channels at 720p, they are comparatively softer and less detailed (mostly visible in facial detail and closeups like blades of grass or a Rolex watch mechanism etc). My "wife" prefers the softer 720p setting, but i much prefer the crisper 1080i setting.

Try both and see which one you prefer :)

Now you know what I mean about watchiing a 720 channel on my 1080p set.
This is why I watch it on the 768 one.
I once had a 720 set, but this 768 one looks better.
Trust me, the 720p channels won't look any different on a 768 monitor than a native 720p one. You can round both of them off to 1 million pixels.
Sony has good scailers.
