想問NVIDIA GeForce 6150SE支唔支援1680x1050解像度? *10分*

請放心，一定可以支援。

至於你出現現時這個設定，是因為你在顯示器內容的進階選項內，選取了「隱藏此監視器無法顯示的模式」一欄。
因為你現時所使用的是17" LCD，所以該選項最大的解像度便為1280 x 1024，這是17"正常顯示的模式。
你祇需要取消該選項，便可以看到其他選項的了。
方法是︰
係桌面空白的地方right click，選「內容」→「設定值」→「進階」→「監視器」
這時你便會看到該選項了。

你的問題我不寫多, 因有GeForce 6150SE 硬件資料, 看下面說明, 要再詳細資料, 到下面Link去看.
