I bought a Dell 5150 recently and got a 17" TFT with it. They were both on a 1 year Euro-wide warranty.
I was about to sell the monitor (boxed new) as I already had one.
I emailed Dell to ask them their warranty status (as the potential buyer asked me for it).
Dell said (received an email earlier today - 24hr turnaround which is OK for Dell) that the Monitor would have NO WARRANTY as the warranty came with the 'system' as a whole.
