I am having Dust behind or inside Panel which is quit annoying on three corners of screen Right TOP, Left Bottom and Right Bottom. Is there any process of removing it.
The problem is from beginning of purchase but dust was small amount and is not considered much of a problem but it increased now.
Purchased directly from Dell or from a reseller? Disassembling this 3 year old monitor would void any warranty. What is the 20 digit serial number? Even if still under the purchased warranty period, Dell could not replace this monitor until you could show us via pictures that the plastic bezel has an obvious defect allowing dust in.
