You are absolutely correct, the Alladin has nothing to do with a blurry image from the cameras. The only tie between the Alladin and the monitor is a video coax cable. Sounds like your monitor has an issue. If you want to prove this, remove the input from the Alladin to the monitor, that will be the final proof. I added a separate monitor for my Alladin system so I can have it up all the time as well as my cameras. If you follow this link, here is a mod that Rob Morgan did that is very similar to mine.

Good luck with the issue.
