Not so simple. Many manufacturers advertise a long warranty and then, when things break, drag their feet, blame improper use or wear and tear, offer workarounds instead of repairs, etc.

A long warranty is only good if the manufacturer is trustworthy. But untrustworthy manufacturers are one of the causes of the whole problem.

A fix might be warranty terms defined by law, where the manufacturer can pick the duration and nothing else. Disputes should be settled in court or by a neutral board of experts.

I have not found it to be the case, one of my displays lasted 7 years and still works, the other gave out in 3, both had 1 year warfanty. Dell and asus respectively.

Think of it the other way round. Long warranties are indicative of a durable, long lasting product. A short warranty, however, does not necessarily indicate a crap product.

Of course this is not a perfect measure, but I do think that a correlation would exist here.

Or, they may also be indicative of the company making its money elsewhere, and thus willing to eat the cost of regular warranty replacement just to keep you tied to their hardware, so that they can exploit you elsewhere.
