I am loving my new LED cinema display - except, I notice a very slight odor of "warm electronics" when it's on. The case certainly gets quite hot - about as warm as my MBP, really.
Its New. All Electronics have some smell to them when they are new. By next week you won't smell anything and be looking for something else to buy to get that smell back.
Sorry to bump this, but mine has this same smell after a good 3 weeks of use. Anyone else's persist this long? I'm a bit paranoid after the reports of toxic Mac Pros, hehe.
