解决办法

检查电源线的连接和电源。

(D-sub接口连接线连接)

检查一下电脑是否都连接正确了。

(用交互式数字视频系统(DVI)连接线连接) 如果你的显示器都连接正常,但是这时屏幕 上还是出现错误信息,请检查一下显示器的 状态是否设在Analog上。 (进入/信号源) 按 钮重新让显示器检测一下输入信号源。

如果出现初始屏幕 (登录屏幕),在应用模式 下启动计算机(Windows ME/2000/XP是安 全模式),然后改变视频卡的频率。(参考当前 计时模式)

注:如果初始屏幕 (登录屏幕) 不出现,则与 服务中心或者与你的经销商联系。

当来自视频卡的信号超过最大的分辨率和频 率时,你能看到这个信息吗。

如果显示屏超过 SXGA 75 Hz,则显

"非最佳模式 推荐模式 : 1680 x 1050 60

Hz"消息。如果显示屏超过 85 Hz,则"非最 佳模式 推荐模式 : 1680 x 1050 60 Hz"消息 出现一分钟,然后消失。请在这一分钟时间 内改回建议模式。(如果重新启动系统,则 会再次显示该消息。)

如果你在连接交互式数字视频系统(DVI)连接 线之前重新启动了系统,或者在系统正在运 行(一些图形卡并没有发送视频信号)的时 候拔出然后再连接上交互式数字视频系统连 接线,显示器将出现黑屏。这时请接上DVI连 接线并重新启动系统。

按下菜单按钮至少5秒钟来解开对 OSD 的锁 定。
