If this is a brand-new (less than 30 days from shipment) system purchased direct from Dell, you have two options:  return for refund, or return for replacement.

If the system was purchased more than 30 days ago, call Dell for warranty replacement of the display assembly.

If it was purchased other than from Dell directly, contact your seller.

definitely had it for longer than 30 days and still under warranty. I haven't done any thing to bend it either it usually stays on a table unless I'm moving it to another table. it also bends inward's like a dent meaning it couldn't be from heat. so it was probably like that from the factory and I'm just noticing it now. also its on the bottom panel not the display
