Alienware 240hz, 27 inch& msi curved 165hz monitor

SMASHED screen the last time I turned them on the screen on the MSI curved monitor was majority cracked and had rainbow lines through it and same goes for the alien wear monitor except it had about 50% of the screen was taken up by these rainbow lines because it’s also cracked. I’m not sure if they still turn on they probably do but I don’t have the cable for them so I can’t turn them on. They are also both about maybe 4+ years old and when you pay €80 you get both of them.
