I need help with Samsung 740BF. When I turn the monitor on it keeps flashing words analog and digital in the upper right corner. After few moments it shows only analog in the upper right corner and shuts down. I checked the user manual and everything but i didn't find any answer. Does anybody know how to fix this?
Try replacing your video cable that leads from your video output on your computer, to your video input on your monitor.
This can basically be one of three things.
1. The cable is screwed (get another one).
2. The graphics card in the computer is screwed (test it with another monitor).
3. The monitor is screwed (test it with another PC).
2 and 3 can be interchanged as it's unlikely both will have failed, so if you test your PC with another monitor and it works, it shows that the video card is ok, so you know it's the monitor.
