Re: [求助] PHILIPS BDM4350UC

BDM4350UC 43英寸4K顯示器 IPS高清窄邊電腦液晶顯示屏
這款我作過一些搜尋，以下是將大陸及各國的網友的評論搜集而成的筆記，版權屬於原作者：

3.該顯示器為鏡面屏。雖然相對於霧面屏，鏡面屏有反光的問題，但是鏡面屏的色彩鮮豔度，通透度卻是霧面屏不能比的。
4.把顯示器的亮度調到最低後，用相機測試未發現閃爍現象，該屏應該是不閃屏。
5.網友測試該顯示器在最大亮度時功耗為90多瓦，比20多寸的顯示器高出不少。但在實際使用時個人感覺亮度在10%~20%就完全夠用了，所以實際使用功耗應該會比測試值低一些。
6.在4k解析度下，刷新率30Hz時有較明顯的拖影，提高到60Hz後，拖影現象大為改善，看上去和普通電視差不多。所以強烈建議：4K，60Hz。
7. 顯示器上所有介面都搭配有原裝線， bizlink的。
8.關於自帶音箱。。。。對音頻有要求的同學還是老老實實的外接音箱吧。

這台不建議在淘寶買,我曾經入手過很短一段時間
使用不到2天就掛了,完全沒徵兆,就完全沒畫面也沒通電的感覺
另外這台有個缺點就是反光嚴重

(老外網友表示)
有 burn in 問題，以及在全淺色的背景上有 dark clouds。
burn-in issues usually happens only in the first 100h of usage.
沒有 FreeSync.

(調校的參考)
A BGR (Blue, Green and Red) stripe subpixel layout is used. This is a less conventional subpixel than RGB (Red, Green and Blue) as ‘expected’ by operating systems including Microsoft Windows and Apple’s MacOS. Windows users should therefore run ClearType to optimise text clarity

the default ‘6500K’ setting was actually pretty decent on our unit and will hopefully be quite useable on most units.


Although ‘2.2’ is reported in the OSD, the monitor actually switches to ‘2.4’ for the gamma setting if ‘User Define’ is selected for ‘Color’. If you cycle to a different gamma setting and then back to ‘2.2’, the monitor will use ‘2.2’ as reported. If the monitor is switched off and the ‘User Define’ setting is being used, gamma will again revert to ‘2.4’ even if ‘2.2’ is displayed. In other words, you have to cycle the gamma setting to something else and then back to ‘2.2’ if you wish
to customise the colour channels and also have correct tracking of the ‘2.2’ curve.

As mentioned above we reduced brightness and made (significant) adjustments on the ‘User Define’ ‘Color’ setting. Be aware that individual units can vary, so these settings aren’t necessarily going to be optimal. Also be aware that we had to re-select ‘2.2’ for the gamma every time the monitor was switched on, as noted previously. If the monitor lost signal for any reason it was not necessary to re-apply this – if you don’t want the hassle of this, the default ‘6500K’ setting was actually
pretty decent on our unit and will hopefully be quite useable on most units.

Brightness= 40 (according to preferences and lighting)
SmartResponse= Fast
Color= User Define
R= 100
G= 84
B= 52

→ DavidChiou: 麼厚，很笨重。支架不能調高低。相較之下，BenQ 32吋
→ DavidChiou: 那台就新潮多了，控制是作得蠻不錯的。
→ Parodius: 支架固定應是尺寸使然，雖然定位是螢幕，不過看看隔壁棚
→ Parodius: 的電視，40"以上應該也沒幾台官配支架是能調整的(？
→ DavidChiou: 的確。我看了下家中電視，厚度的確也是一個拳頭厚。
→ DavidChiou: 這台43吋算是電視改來的 :D
