Intermittent fuzzy monitor display

[vegasrwg]

I have a 19 inch Likom monitor that works great except recently it goes fuzzy every few minutes when viewing photos. If I reset the power to the monitor all is well for another few minutes then fuzzy again. What can I do to solve this problem.

Is this a big fat, heavy monitor or a slim light LCD monitor?
