We bought a bunch of them at DISQUS, our current failure rate is about 20-30% failed within the first three months of use. Would not buy again.

- pavel_lishin 14y agoIf they're less than half the price of a comparable Dell, a 30% failure rate seems acceptable. Just buy some spares, right?
- scott_s 14y agoIt depends on how much you value the extra time and effort it takes to replace them. If you buy spares ahead of time to negate that time and effort, then have you really saved money?
- pyre 14y agoThe point is that a 30% failure rate is less than the 50% discount so you only end up saving 20%, with the spares included in the purchase.
- ZachPruckowski 14y agoBut if 20-30% failed in the first few months of an expected 5+ year life cycle, that's indicative of a >50% failure rate in the medium to long term. You'll probably come out a loser in monitor-years/dollar.
- jff 14y agoThat does not necessarily follow. See the "bathtub curve".
- excuse-me 14y agoSee also "time value of money" - if you don't have to buy the spares until they fail, all that extra money is worth something to you. There is a reason Toyota and co don't have 6months of parts on hand - and it isn't due to shortage of shelf space
- ww520 14y agoIt's 30% failure in 3 months. How high can that go in 6 months, in 12 months, or in the expected life span of a Dell monitor?
- HeyLaughingBoy 14y agoManufactured products tend to have two spikes in their failure rate: soon after being put into service (manufacturing defects showing up when the product has been used a bit) and near end of life (parts are wearing out due to long usage). In the middle, the failure rate is pretty flat. Monitors failing within 3 months suggests that you're seeing the infant mortality part of the curve. If a particular monitor lasts 3 months, it will likely last for many years.

- cjdavis 14y agoIt's more of two slopes rather than two spikes: https://en.wikipedia.org/wiki/Bathtub_curve https://en.wikipedia.org/wiki/Bathtub_curve
- dvdhsu 14y agoTangentially related, but still interesting: most people think hard drives have a bathtub curve when failure rate is plotted against time. Turns out this isn't true. Schroeder and Gibson: "Contrary to common and proposed models, hard drive failure rates don’t enter steady state after the first year of operation. Instead failure rates seem to steadily increase over time." http://www.pdl.cmu.edu/PDL-FTP/Failure/CMU-PDL-06-111.pdf http://www.pdl.cmu.edu/PDL-FTP/Failure/CMU-PDL-06-111.pdf
- Xcelerate 14y agoAll the same brand, or from multiple Korean sources?
- fuzzythinker 14y agoIf that's true, the HP ZR2740w is a much better choice. Got mine for ~$650 few months ago, so it'll be < 2x of these prices but no need to worry if they will fail or not.
- bradfa 14y agoHow do you like the anti-glare on the ZR2740w? I've found it to be rather intrusive and annoying, especially compared to the ZR2440w's coating.
- fuzzythinker 14y agoI think it actually helps reduce eyes strain. I have it setup in a standing desk like setup so it's ~15" in front of me, so distance is just few inches apart than a standard distance to a laptop screen. My eyes don't get tired at all, where as looking at my laptop screen does, but that's probably due to the pixel density in addition to the reflectiveness.
- hastur 14y agoHow did warranty claims / returns work for you? Did the seller honor them properly?
- ntaylor 14y agoWhich model did you buy? (make, etc)
