DVI cable/adaptor dilemma

[bowman]

I purchased Fujitsu-Siemens 19" TFT monitor recently but I didn't get DVI cable in package. In documentation there stands that there should be audio, analog and digital cable within. Anyways I found one analog to DVI adapter. I wanted to ask some questions:
1. If analog calbe is plugged in monitor and other side is plugged in analog-DVI adapter and then in graphic card's DVI slot is the signal still analog because when I boot the computer I get OSD resolution and signal message and there still stands analog?
2. If I put DVI adaptors on both sides of analog calbe and plug them into DVI slots in monitor and graphic card, do I get digital signal then?

Which part of the denomination "analog cable" makes you think it transmits a digital signal?

If you want a digital transmission, you need to use a DVI cable. No way around it.

Yes I assumed that too (that I need real DVI cable for digital signal), even before this question. It was kinda logical but I wanted to be sure. Aber trotzdem danke alda! ;)
Actually main reason for trying to change analog to digital transmission was shaking of a picture, interlacing, which was visible after I carefully looked at the letters or grey/white/black background on the screen. I thought that something wasn't ok with the cable, but after I saw friend's Samsung Syncmaster 17" and how it works perfect in 1280*1024 resolution on 75Hz I though it could be something else (nearby subwoofer, wireless mouse+keyboard, 4 things plugged into the socket extension). I plugged monitor power cable into another socket on the other side of the room and picture was ok. I didn't believe that it could be such problem. I will test it now a bit to see if it's surely that problem.

Also I think that it could be because of transformator which is built into the monitor on the upper side of it. Those interlacings are just in upper side of the screen.

I'd have said you need to lower the refresh rate to 60. This won't influence the display at all, but the slower signal frequency may let the re-digitizer inside the unit produce more accurate results.

LCD monitors should always be set to 60 Hz for the best picture quality.
