= =||| 小的也有這種問題（青雲G4 TI4280＋170S4），也是在看PCDVD時比較嚴重，有時動不動就閃一下，不過其他表現就滿意多了....^^" 不過，這樣的價錢獲得這樣的品質，小弟已經粉滿意了！

再來是剛剛看到相關鍵結漏光的問題，其實薄框的LCD多多少少都會有，小弟的漏光情形沒有在左下，反而是在右側邊，不過不是很嚴重，只有一相當小小的區域而已，閃的問題還是比較苦惱！

對了！剛剛是過70HZ，居然的電源的部分換一直閃....不知道是什麼問題，不過閃的問題變的比較輕微，不過看到他一直在閃...想想還是調回來好了...

我新買了170s4
也是有切換時會閃的問題
切成70 or 75 Hz
會好一點
可是畫面會變大
蠻煩的
果然一分錢一分貨

There is one more interesting thing about this display: the backlight lamp is modulated. To control brightness, the manufacturer used a width-pulse modulation of the lamp power supply (as you know, LCD displays use fluorescent lamps with high-frequency power supply, about 40…60kHz) with a frequency of about 260Hz. This was quite clear in the oscillograms, taken at a low brightness level (when brightness is high, the impulse width gets larger and independent impulses practically converge into one):

Of course, the eye cannot discern such frequencies, so all the things mentioned above are nothing more but just a curious fact.

xbitlabs的評測提過一種背光燈（？）閃爍，亮度低的時候
是不是這種？
