imac嘅所謂4.5k係咪只為keep住retina個朵

好哋哋4k唔得嘅係咁屎忽痕
4k mon 睇 4k / 1080p 片係咪會靚仔啲

堅持218ppi

係幾無謂，4k mon睇4k/1080片應該清過4.5k

4.5除4或除1唔可以整數除盡所以做唔到pixel之間一對一mapping咁嘅概念，同2k mon睇2k source就清，睇1080p反而無1080p mon清一樣，數學問題，2520/2160=1.1667，畀apple都唔會整到0.1667粒pixel

m1 mac mini 好似144hz 又4k，好似好好多咁係咪咁話

搞到強逼症發作

你有強逼症就係你唔啱了，用apple產品，係要你就產品唔係產品就你，而家咁小事，唔睇片/只睇4.5K片咪得，睇字係清過4K喎係咪先，有強逼症係用家問題

另外，你因應你嘅個人需要而買更適合嘅mac mini唔去買iMac就會代表你窮

睇片唔full screen 咪得

原來係咁 學到野

不過你咪理 最緊要呃到消費者

此po已完
係for剪片人慳位放toolbar又同時睇到4k畫面
一般用家無對比就無傷害
一般人唔介意多舊嘢嘅話mini + mon 好過，又高hz又4k，而且插usb可以順手啲，touch wood壞mon拎個士啤mon又可以用住先

我覺得係想保住retina個名多d

最大問題都係原生LCD resolution 唔用走去用低resolution 啫
你要咁算死草所有1440p monitor 都唔適合睇片

你由頭到尾都曲解，根本唔會較低resolution去用，個問題係個mon裝4.5K嘅pixels去睇4K或1080p片就必然會遇到所提到嘅問題，pixels數目係整定咗喺硬件上，唔關用咩resolution事，你似乎連個問題係乜都未理解到就喺到話最大問題係乜乜乜

第二點，我指嘅係用隻mon去睇個唔夾resolution嘅片源，無話所有1440p mon都唔啱睇片，1440p mon睇返1440p片源係會正常亦應該清過1080p mon睇1080p或2K嘅片

曲乜鬼解, 你想講pixel to pixel, dot to dot. 咪以為係啲好sophisticated concept
人地video playback upscale downscale 都都大把algorithm

係LCD native resolution to non-native 先麻煩同用唔到呢啲algorithm

第二點就係你算死草既嘢, 1440p 睇1080p 會點？

你都幾撚煩，有algorithm都只係盡量去scale，個問題係mathematically無一個完美solution，所以1440p睇1080p片係會無1080p mon睇1080p片咁sharp

你自己睇我用乜mon隻mon乜resolution，一直講事實唔知你有乜好拗，煩撚過閪，又唔見得你有乜高見，戇撚鳩

你都幾撚煩同戇鳩. 最緊要係理解力低
你試下4.5k mon 較做4k 再睇4k 片同4.5k 直接睇4k 片邊個畫質好啲就係個algorithm 分別
知你冇4.5k 芒, 同理你用1440p 芒較到1080p or any nonnative resolution 原理一樣

仲要貼張自己用緊既mac 同芒成個戇鳩佬咁

你係真傻或蠢，你肯多用吓腦就會知自己幾撚蠢或者google都畀到答案你，我就唔花時間了

好明顯你學藝不精仲要先撩者賤喇
叫人google 連source 都拎唔出

你放心, 我都唔想晒時間教精你

1080p嘅片等於有1920×1080=2073600咁多點

放喺1080p嘅mon到都係出到咁多嘢出嚟

放落1440p係唔會多過2073600咁多原生嘅pixel，1440p嘅mon有3686400咁多點，中間差咗3686400-2073600＝1612800只能憑空由就近pixel填出嚟，已經確定咗係唔會sharp過1080p，除非有machine learning model train好識得補，但有亦都唔會係real time

個問題係resolution唔夾就唔夾，靠週圍嘅pixel補返啲色係唔會按比例完美咁補返，例如2K vs 1080p就因為唔會搵到0.333粒pixel，其實簡單加減乘除就知，不需要google，係因為你蠢先叫你去google，不過我又想睇吓你點樣將math/science扭曲所以貼埋source：

Does 1080p look worse on 1440p monitor than it would on a monitor designed for 1080p?
It can. 1440p increases the number of pixels in the display by 1/3rd in both the X and y axes. That means it needs to stretch the pixels to 4/3 their original size. Since 4/3rds isn’t an integral number, the scaling algorithm is forced to average the color of the pixels. There’s a few ways to do this to try and do it to best reproduce the picture, but the simplest linear scaling method is just to take every 3x3 pixel block, and map them into a 4x4 square by breaking the pixels into smaller pieces and averaging the colors; like so:

You end up with something like this as a result:


Note how the blending of colors makes it a little more muddy. When you do that across the whole image, what it does is make all the sharp features less distinct and kind of fuzzy.

我用緊4k mon
影片縮放algorithm唔會完美
高bitrate嘅片就冇乜事
低質個d會blur

其實你可以唔好講啲咁蠢嘅嘢，你將個4.5K mon較做4K，你隻4.5K mon都係4.5K數量嘅pixels，等於你個較完之後嘅4K source喺隻mon到show返出嚟都係經過upscaling，除非係你留黑邊嗰種較法

你同用返4.5K settings去睇一條4K片再經upscaling出嚟做比較係無意思的，你只係比較緊OS level嘅scaling同條片嘅scaling，根本無撚意思

點解要同個弱智解釋咁多野

咁又唔使咁快拆穿住，我想睇佢表演埋點扭曲空間先

你用imac打開fcp 再睇下你剪片果陣可唔可以點對點4k playback咁剪囉 dllm4.5k入面4k係片佔左8成area 得番果少少位你攝到timeline toolbar果堆野咩

咁講嘅話27吋5k都係多舊魚啦
邊有5k source啫？

好過4.5kmon播4k 因為1440p播4:3係一個好合理好易做compensation嘅比例 電腦行業訂standard果陣係有諗過依d野
不過4k本身d標準就99地 Cinema4k同主流電子行業4k都唔一樣 無論imac個mon咩resolution都唔保證無野
