If you are certain that the monitor has nothing to do with signal problems, and you have exhausted all you other options. First check and test the outlet that you are plugging the systems into to make sure it works. Secondly, verify the systems that are giving you these signal problems is compatible with the video cards that you have installed. (The video drivers are correctly installed in the computer). Then, check the video connection port, which could also be the possible source of the problem.
