我之前既mon既像數係1024x708,但而家既新mon1280x1024.....

19" LCD (4:3) 原生解象度為1280X1024，所以SET 1280X1024 是認該清過1024X768 的
你可以 SET 1280X1024之後，於MON 上按下 AUTO ，等它辨識訊號。
如無改善，請檢查 MON 和電腦之間的接線是否有問題(如不是使用跟機的那一條)

19' monitor optiomal resolution should be 1280x1024, if your computer cannot show it clearly, it may related to the "power" of your display card, try to set it back to 1024 x 768 to see the difference , if the result is 1024x768 clear and 1280 x 1024 not clear, then you may need to change display card la.
