Difference between 720p and 1080p

Tompior · 01-20-2008, 05:20 PM

Hello, I was always wondering. Is there ANY difference in the game view between for example COD4 in 1080p on 37" TV and COD4 in 720p on 32" ?
I know that on 32" everything is smaller, but is there any graphick difference?

(i'm sitting 3meters from tv)

There is no visible difference from 1080p and 720p.

The human eye cannot differentiate them, and anyone who says they can see a difference, is seeing a placebo. They're told It's better, so they'll think it is.

Get a 1080i/720p TV. Cheaper, and just as effective.

Nah, i have my panasonic tx-32 lx70p ^^
Games in 720p looks awesome and i just wanted to know, did i lose something ^^

1. Your wrong.

2. Your just a plain moron if you believe the crap you just typed.

People can tell the difference. In fact there is a difference. Now not everyone can see the difference this is true. But a lot of people can. I can see the difference. Did I say it was a big difference? No. However there is a difference. Details of games and movies are just that much more enhanced.

If you can't see the difference that isn't my fault nor the manufactures fault. However don't go around spewing fourth that there isn't a difference and that no one can see a difference. Because there is a difference and people can see the difference, just not everyone.

Wow, there is a post? Stickied? It PROVES the fucking human eye cannot even see the difference between 720p, and 1080p.

You stupid moron.

Really COD4 crazy. And wheres the scientific proof. You probably sit 1cm away from the screen, an anytime you look away from it you cry blood. Dick.

You stupid moron.

Seriously that thread is a joke. I know which one you speak of. And honestly those screen are huge and anything would be distorted on them. As you go bigger in screen size you do loose definition. Simple concept.

That thread doesn't proof anything. It proved that those people that where there couldn't tell the difference. Did they take into account the entire world? No, they didn't.

Next time you come into a thread to try and bust on me. Don't. Your a stupid fuck for even trying to do so.

And it doesn't prove a damn thing. Again did they test the entire world of people? No they didn't.

1080p and the Acuity of Human Vision

1080p resolution

"1080p provides the sharpest, most lifelike picture possible." "1080p combines high resolution with a high frame rate, so you see more detail from second to second." This marketing copy is largely accurate. 1080p can be significantly better that 1080i, 720p, 480p or 480i. But, (there’s always a "but") there are qualifications. The most obvious qualification: Is this performance improvement manifest under real world viewing conditions? After all, one can purchase 200mph speed-rated tires for a Toyota Prius®. Expectations of a real performance improvement based on such an investment will likely go unfulfilled, however! In the consumer electronics world we have to ask a similar question. I can buy 1080p gear, but will I see the difference? The answer to this question is a bit more ambiguous.
Measuring Human Vision

To fully understand the implications of high resolution and high definition we must first explore the limitations of human vision. The Dictionary of Visual Science defines visual acuity as "acuteness or clearness of vision, especially form vision, which is dependent on the sharpness of the retinal focus within the eye, the sensitivity of the nervous elements, and the interpretative faculty of the brain." Simply put, our eyes have a resolution limit. Beyond our ability to see it, increased image resolution is simply an academic exercise. It can have no real part in improving the viewing experience. Unlike hearing, our visual acuity is unambiguous and relatively simple to measure.

Vision is measured using a few different tools. The most familiar is called the Snellen chart. Using this tool an optometrist or physician would ask you, from a standardized distance of twenty feet (six meters in countries that use the metric system), to read the "letters" on the chart. The smallest line that can be read accurately defines the acuity of vision, which is expressed in a quasi-fractional manner. 20/20 means that a subject can read the line that defines average vision from the prescribed twenty feet away. 20/10 means that same subject can read, from a distance of twenty feet, the line that a subject with "normal" vision could only read from ten feet. 20/10 vision is therefore twice as good as 20/20. Similarly, 20/40 is half as good with the subject being able to read at twenty feet what someone with normal vision could read at forty.

The next part of the puzzle is applying this understanding to a video display or other image composed of heterogeneous elements. The human eye’s resolution (acuity) is directly proportional to the size of the elements of the image and inversely proportional to distance from the elements. This relationship is best expressed in degrees.

It's common knowledge that people have a finite field of view, which is normally considered from its upper limit. Technically this is said to be the angular extent of the observable world that is seen at any given moment. Roughly put, we can see things that exist within a known angle with the apex being our nose. Staring straight ahead the average person has a stereoscopic field of view (not including peripheral vision which allows nearly a 180 degree field of view) of about 100 degrees. In a similar manner we have a lower limit to our field of view. Scientists express this as an angle as well, but because that angle is less than a degree we have to use the language of engineering and describe this lower limit in minutes of arc.

Everyone knows from their high school geometry classes that a circle is 360 degrees (360°). For angles smaller than 1 degree we use arcminutes and arcseconds as a measurement. An arcminute is equal to one sixtieth (1/60) of one degree. "Normal" visual acuity is considered to be the ability to recognize an optotype (letter on the Snellen chart) when it subtends 5 minutes of arc. We can most certainly see objects below this level, as this describes only our ability to recognize a very specific shape. Taking this a step further, we find that the lower limit of "resolution" of average eyes equates to roughly ½ the limit of acuity. In other words, the average person cannot see more than two spots (pixels if you will) separated by less than 2 arcminutes of angle.
