Monitor hadana kenekuta deela hadaganna eka thamai thiyenne. oyaa eka eka eeva karanna yana ekata vadiya eeka godak hondai.

Can't exactly say what the problem is, most likely the monitor; but it also could be the VGA cable or even the graphics card.
Can you test it on a different PC with a different cable?
