This sort of damage would not be covered by the Dell monitor warranty. Dell does not repair monitors or offer disassembly instructions for this AW2518H. You will have to seek a local Monitor/TV repair center to see if they can disassemble. Then look for the LCD panel on 3rd party sites. Note, the cost of diagnosis and repair might outweigh the current used market value of the AW2518H.
My third party monitor stand broke off and the AW2518H hit something on the table and cracked the screen on the top right corner. Does anyone know how much or if it is possible to replace it since I want to use it as a second monitor?
AW2518H, cracked screen, replace options?
