I have a chance to purchase a LM270WQ1-SDDB replacement screen. Will it fit into my 2010 27" imac. I can’t find an answer to this question.
Most likely because we work off of Apples part numbers not the vendors (we don’t try to keep track of all of the suppler #s). The part you are looking for is Apples P/N: LCD Assembly, 27" 661-5568. With that you should be able to cross reference to a vendors part if the supplier offers it. Otherwise, I think you’ll need to find a different part supplier.
