RMBP 15" - Terrible noises when using external display.mp4
RMBP 15"
BenQ XL2420T
MiniDP - DP
開在100Hz的時候沒什麼問題，開到120Hz之後螢幕上會出現大量的橫向雜訊
同樣的問題在以Bootcamp跑Windows的情況下並不會發生
奇妙的是，螢幕剛接上去的時候，OS X預設是輸出60Hz，Option可以調到100Hz，沒有120Hz
但是一旦開到了100Hz，這時候就會多出120Hz的選項可以在調上去
不確定是不是其實OSX並不支援120Hz，UI會跳出來其實是個Bug....
The external display works fine when it runs under 60Hz and 100Hz.
Once it's configured to 120Hz, horizontal noises flys out.
Weird part is, when the external display first attaches, there're actually only 60Hz and 100Hz options.
Once 100Hz selected, then there's 120Hz shows up.
Not quite sure if OS X actually not supporting 120Hz, and it's a bug to show 120Hz option...
Same issue does not happen when running Windows with Bootcamp.
