Hi, We facing one similar problem in our computers i.e we are newly constructed our design department after that shifted our computers but our computer desktop screen is vibrating. we are conducted our electrical maintainance person he told that is UPS problem, then we changed the UPS also again we are facing that problem in that room only. then we put lcd monitors that problem is solved. But in other monitors why the computer desktop screen is vibrating please give a suggestion to me. Regards, Raju.N.G
