Samsung Announces Zero Dead Pixel Policy

Kez writes "A result for the consumer as Samsung declares any TFT that they sell from today onwards should be guaranteed dead pixel free. Until now, purchasing a TFT has been a gamble, given that dead pixels, while extremely annoying, did not necessarily entitle the consumer to a replacement monitor. Unfortunately, anybody who bought a Samsung TFT before today is not covered by the new policy." Update: 01/01 19:49 GMT by M : The new policy only applies in S. Korea. Suck.

      Many people aren't aware that font sizes and pixel sizes are independent issues, and get a bigger display so that the same pixel-size graphics are "bigger". Silly, I know, but the problem is particularly acute on Windows, because of Really Stupid (tm) windows third-party application coders who hardcode pixel sizes everywhere.

      First rule of modern GUI design: Natural Units and Vector Graphics, not Pixels!

      An 8 POINT font should be the same SIZE - 8 points (duh!) - on a 1280x1024 or 1600x1200 display - it should just be a bit clearer on a 1600x1200 display. When I set my document zoom to 100% and hold an A4 sheet up to the display, the A4 sheet on screen better be the same size as the physical sheet, or there'll be a bug report filed!

      Actually, the Display size is usually autodetected from DPMS these days (check output of xdpyinfo command for DPI information).

      However, if DPMS is wrong (can happen, particularly on cheap monitors), or you just want to fiddle, in your X config file, you put e.g.

      DisplaySize 400 300

      Where 400 and 300 are the X and Y screen dimensions in mm in the relevant "Monitor" section of the file. Yes, this is documented in the f-ing manual, but hey.

    Why anyone would ever actually believe that you couldn't return an LCD (or laptop) with a dead pixel. This is a manufacturing defect, plain and simple. Every customer expects there will be NO dead pixels, so my guess is that proving to a court of law that a dead pixel is a de facto breach of various implied warranties (and probably express warranties that come with the unit as well) would not be difficult.

    Any decent credit card will likely supply the consumer with enough tools to reject a charge for such an item, if refused. Further, if pushed, I sincerely doubt any company would believe that they could win in a case where they're trying to foist an obviously defective monitor on someone by claiming that the defect is really bad enough to be a defect. Right. Most states provide a damages multiplier for unfair business practices such as this. This means if push actually did come to shove and you had to go to small claims court, you'd get double or triple your money back.

    My guess? Samsung realizes the above to be true, and is trying to play this to their advantage.

      In the UK you have no inherent right to return something no questions asked, unless as covered under the Distance Selling Act as stated above. If you made this purchase instore, then you are only covered under the Sales of Goods act, or store policy. Basically the Sales of Goods act says you can return an item for refund if the goods are not fit for the purpose they were sold for, not bought for (common mistake, they have to be sold for a purpose and fulfil that purpose, they can be bought for any reason at all).

      As most LCT/TFT are sold as Class 2 items, and state so on the box or the unit themselves, certain number of dead pixels are allowed for on the screen, and this does not affect the requirement that the item be fit for the purpose of viewing, IE you cannot return a Class 2 device that is within teh ISO 13406-2 Class 2 limits. Your local Trading Standards office will confirm this.

      The reason this ISO class system was created was because TFT screens were incredibally hard to make without dead pixels, even todays manufacturing lines have a low yield of perfect screens. So you have a choice, accept the possibility of a few dead pixels and get a cheaper screen, or demand a perfect screen and pay more for it. The consumer cant always stamp their feet and demand high quality for low price. A certain level of quality, yes, but not perfection 100% of the time.

In almost all electronics stores I patronize, you could just take the monitor back for a refund, even if it wasn't actually defective. Retailers would rather not buy items that get taken back all the time, so manufacturers have a motivation for improving display quality.

      It is the very act of "whining" that drives improvements in both product and service. If manufacturers could get away with foisting crappy products on everbody, you'd better believe they would (see: Microsoft :P), and Samsung's new policy never would've happened. It is only because customer whining can have a tangible impact on profits that these companies realize they have to work harder to stay competitive.

    Sorry, but that's just not true. "dead" pixels do one of two things. They either stick open or stick closed. The end result is that you have a dot on the screen that either is very obviously dark when the surrounding material is light, or vice-versa.

    While this isn't terribly noticible when playing movies or video games, it is quite noticible when using most traditional 2D desktop apps. A dark pixel in the middle of your otherwise mostly white word-processing session becomes obvious.

    Case-in-point is the support wires in Sony Trinitron monitors. Very, very fine horizontal lines at the 1/3 and 2/3 levels on the screen are used to hold a mesh in place which gives the Trinitron series a great display. Every Trinitron style screen I've ever sold, I got asked, immediately, what the story was with the lines. Most customers balked somewhat, but all eventually agreed to live with it.

    Dead pixels are, in fact, defects. I don't intend to purchase a defective product out of the box. A product should be free of manufacturing faults for the period of its warranty, or be replaced/repaired. Cosmetic damage to say a bezel, or a power cord is trivial to ignore, but a dead pixel is a flaw in the display's ability to display accurately what it's told to.

    As such, I will never buy a laptop or LCD without being allowed to first verify its display is without flaw. A retailer who refuses to allow me to confirm the proper functioning of the device before purchase/departure is a retailer who loses my business. Period.
