EIZO的5年保只有零件,面板3年保
DELL 的東西就比較一般,當初27吋那台18~19k多(光華賣22~23k) |

看來似乎可以期待..
LED死白的問題真的會影響爽度. 看久了眼睛也常會不舒服.

校正後的brightness是在26% 所以看起來可以避免閃爍問題? 引自原文: Out of the box the screen gives a luminance of ~114 cd/m2 at the 20% brightness setting (See our brightness and contrast stability tests) which should prove adequate as a lower level of adjustment for those who still want to avoid the use of PWM for lower brightness levels. 比較起其它TFT有測的螢幕 ASUS PB278Q - Pulse Width Modulation Used Yes Cycling Frequency ~240 Hz Possible Flicker at 100% Brightness No 50% Brightness Yes 10% Brightness Yes U2713HM - Pulse Width Modulation Used No Cycling Frequency n/a Possible Flicker at 100% Brightness No 50% Brightness No 0% Brightness No 這代表U2713HM是PWM-free的嗎 看到這個蠻有趣的, 我也拿我的螢幕來試 用手機的相照找看看有沒有因為亮度的改變水波紋能有改善 結果brightness要到100%水波紋才會消失 看起來真糟糕  倒是ipad3怎麼用都拍不出水波紋, 難不成ipad本身是比較PWM-free的性質嗎 此文章於 2013-02-18 01:34 AM 被 oScARSh 編輯. |

引用U2713HM測試的原文:
Interestingly the Dell U2713HM appears to not use PWM at all for dimming of the backlight. Even at 0% brightness there was no sign of the usual splitting of the white line that you'd expect to see in these tests. We carried out the checks at an even slower shutter speed which returned the same result. This is great news for those who are affected by flickering backlights and suffer from eye fatigue and eye strain. 看起來我如果要買2560x1440螢幕 可能要改選U2713HM了 |

市價會打牌價幾折，
團購的話不知U2413有沒有機會逼近10K。 |

太難了∼∼∼這個規格給10k的機會可能有點渺茫∼ 能在12500以內就該高興∼∼ 雖然我猜台灣的售價大概要14-15k... |

有一點要注意 評測雖提到均勻性補償在U2413有作用，但也僅限於某些模式 而且這功能開啟的時候亮度是不能調整的 亮度會固定在出廠預設值50% 這亮度對一般人來說很明顯是太亮了 總之如果你希望調整亮度的話Uniformity Compensation就會無法開啟 問題是一般人不可能受的了原廠預設亮度的吧 結論是：跟U2713H一樣，這功能基本上是雞肋，有等於沒有 原文: "On the U2413 you cannot even change the brightness setting if you want uniformity compensation turned on! If you switch to the 'custom color' mode, the brightness control can be changed in the OSD, but it makes no difference to the actual visible luminance of the display. This was another odd choice from Dell. Not only can you not enable this feature in the main factory calibrated or hardware calibrated modes, but if you do enable it in the other supporting presets, you're locked at a very high luminance without the ability to change it!" |

可能要在 EIZO ev2436w 和 Dell U2413 選一台。
大家會選？ |

關於這件事我問過TFT那篇review的作者了 他說他測了三次都是一樣的結果，也就是Uniformity Compensation是無效的 但他測U2413這功能卻是有作用的 所以他不排除可能是他手上那台U2713H有瑕疵  |
