反向思考：Why 4K TVs are stupid
 

http://asia.cnet.com/why-4k-tvs-are-stupid-62213238.htm

Brace yourself for some math
The human eye, for all its amazingness, has a finite resolution. This is why you can read your computer screen from where you're sitting, but not if you're on the other side of the room. Everyone is different, but the average person with 20/20 vision can resolve 1 arcminute. One arcminute is 1/60th a degree. If you assume your field of vision is 180 degrees (it's not, but go with me here), and you take 1 degree of that, you're able to resolve a 1/60th sliver of that degree.

Close up this means you can see hairs on your arm, wrinkles on your thumb, and so on. At distance, these fine details disappear. If a friend waves at you from across a field, you can probably see the person's thumbs, but not any wrinkles or hair. Far enough away, you probably won't even be able to see thumbs, unless those are some really, really big thumbs.

One arcminute of resolution is a best-case scenario. On a black on white vision chart, this holds true. Reduce the contrast of the object with the background, add color, and many other factors limit your ability to resolve resolution.

This math, or just looking at your TV, tells you that you can't see individual pixels.

看到展式是用sony的顯示器，
現在已經有那麼高解析度的顯示器了嗎？
那麼高的解析度如果是42吋的螢幕應該也沒多大效果吧 :ase

這就要用賈伯斯提出的視網膜解析度來衡量了
離手機的距離,用300 PPI可以看不到網格
那離螢幕的距離要用到多少PPI?
反算回去就知道有沒有差異了

panasonic之前有展出145吋8K的PDP
Youtube上的4K我用42吋PDP看其實還是看得出跟1080P的差別

連攝影機都已經有8K解析度了，看來膠捲過幾年就會完全被淘汰掉了

雖然膠捲的色澤和光影質感仍舊無可取代，不過數位的便利和低成本才是趨勢...

你忘了算上近視/老花度數.... :rolleyes:

這一點我就真的比較納悶，
不管訊源的解析度多高，
在顯示端的解析度是多少我們眼睛看到的就是多少呀，
也就是不管影片是2k、4k或8k，
只要電視是1080p那我們看到的也就是1080p呀，
有可能因為訊源高就比較清晰嗎？

你看到的是使用1080P 的螢幕

顯示著 480P 的畫面 ~ 這樣懂沒? :D

不好意思，你的比喻我更加看不懂 :ase

上面seraphic兄提到在1080p的顯示器上看4k的影片及看1080p的影片有差別，
意思應該是4k比較好，
不過我認為應該不至於，
就我在720p解析度的螢幕上看720p及1080p的影片來比，
其實兩個解析度的影片看起來差不多，
也就是高解析影片在低解析的顯示器上表現並不會比1：1mapping來的好
