AE black screen unable use 無法繪圖

The comp  screen always show nothing and black (when I adjust other color or scale also show black screen)
I can't draw and put any graphic on there.(also show me black)
Is it my Graphics card problem? or my AE setting problem?

設定一個新comp 都是黑屏無法做任何縮放（一樣全黑）或更改顏色

也不能在上面繪製圖型或放入圖片都還是看不到
是我電腦的顯卡有問題嗎？還是設定哪裡的問題呢？
