1、投影机连接视频信号源(如电脑等)后,按电源按键开机,投影画面提示“无信号”。
2、按“Source”按键,选择输入信号源(与信号线连接投影机的接口一致)。
例:视频信号源通过VGA线与投影机的“Computerin-1”接口连接(如下图红框), 不能与“Monitor-Out”接口连接(如下图绿框)。
按“Source”按键,选择输入信号源为“计算机1/YPbPr1”
3、将视频信号源(如电脑等)的视频输出分辨率设置为投影机的真实分辨率。以MS3081与电脑连接为例:MS3081真实分辨率为800*600,则将电脑分辨率设置为800*600。
Windows XP系统操作 方法:在电脑桌面点击右键-属性-设置-调节“屏幕分辨率”-确定。
Windows 7及以上系统操作方法:在电脑桌面点击右键-屏幕分辨率-调节“分辨率”-确定
4、若视频信号源为笔记本电脑,则: 方法一:切换笔记本电脑显屏模式(同时按FN+FX(X=1~12),如下图);
方法二(Windows 7及以上系统):控制面板-显示-连接到投影仪-选择“复制”(如下图红框)。
5、视频数据线使用标准线材(随机附送)。 若使用自行定制线材,可能会因接头焊接不好、线材质量不好或线材过长,导致信号强度衰减严重,投影机无法识别到信号。
6、如情况依旧,请您尝试将投影机连接其他视频信号源(如其他台式电脑等)及视频数据线投影,再按步骤2至步骤3操作。
7、以上操作均无法解决问题,需联系明基服务网点检测,www.benq.com.cn-服务支持-信息查询-服务网点。
