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.
That's from Newegg.com themselves, if you want Samsung's replacement policy, you don't contact the merchant, you would call Samsung.
I can't seem to find a samsung source that says this? But it is very very nice, and about time, I think! Nowhere else do you buy products that are slightly defect (and still very expensive!)...
Any technology distinguishable from magic, is insufficiently advanced.
P.S. does anyone else think op is trying to bring that forum down...

This link here is to Samsungs page on dead pixel policy (last updated 2004-06-18) and has no mention of this "new" policy. It still stands that they won't replace an in warranty monitor as follows:
I have to agree with you here...
In the UK atleast and if you buy online we have a legal right to return any bought product before 14? days have passed with no questions asked, as long as its still worth selling.
I have a 20" HP LCD which has no dead pixels... 1600x1200 of pure sexyness..
But I'd feel robbed if I thought I'd paid the money for that and got more than say 3 dead pixels in conspicuous places.
I laugh at Sony's PSP dead pixel policy and honour Nintendo's 0 tolerance offer...
woopy do how many pixels there are on a monitor -- it does not give companies the right to sell faulty products. If they cant sell them perfect they shouldnt be selling them at all.
In the uk I think I can legally return any product by law if I'm not happy with what I bought... but I also think you *need* to kick up the shit in the showroom you bought it from to do so. (trading standards would come down on them like a ton of bricks) And bad publicity usually makes any store stand down.
Rather than making it up to the consumer to put their own money up front to ensure satisfaction.. I believe it should be law that you recieve (for the same price) a product in the same condition someone else could. Because if I can get a TFT with no dead pixels... why the hell should I buy another that might?
There are several classes for TFT displays which precisely state how many defective pixels the display may have. The ISO standard for this is 13406-2. Most displays sold today do not belong to the no-dead-pixel-at-all class, so customers cannot whine. It usually clearly states on the box somewhere with the other technical data to which class a certain modell belongs.
So no unfair business tactics at all.
Yes -- look for dead pixels on a white background, then change the background color to black and look for pixels that are stuck on. The latter part may be easier if you try several backgrounds with different solid colors.
What the anonymous coward said about a checkerboard does not make sense to me -- how is it easier to look for dead pixels when every other pixel is off? (And same logic applies to pixels stuck on.) However, his method is good for auto-adjusting LCD color, which is another discussion.
The zero dead pixel policy is currently only available in Korea.
Apple's policy is not on the public record, but it can best be summed up by "the more annoying the pixels, the more likely it is to be considered unacceptable". (I've read the policy, it's quite reasonable) You have to take a display into an Apple service center for the tech to reference the policy to determine if the display is considered defective. This is probably to take the burdon off Apple where customers might try to stretch the wording of a quality policy beyond reason. They may say yes or no to a description given to them over the phone, but I haven't tried that. But for certain, Apple does not have a zero-dead-pixel policy.

None ... The United States make absolutely nothing in the entire computer industry entirely in the United States. Assembled from others part yes , manufactured none , even the PowerPC from IBM have some parts made oversea and in Canada.
There are only two company making LCD or ODM:
Samsungs
Phillips
the rest are sub-brand from the two above.

In the UK atleast and if you buy online we have a legal right to return any bought product before 14? days have passed with no questions asked, as long as its still worth selling.
Yes, this is called the distance selling act, you have up to 14 days to signal your intention to return the product citing the aforementioned act, and you are responsable for carraige charges. The goods have to be as new for this to apply.
In the uk I think I can legally return any product by law if I'm not happy with what I bought... but I also think you *need* to kick up the shit in the showroom you bought it from to do so. (trading standards would come down on them like a ton of bricks) And bad publicity usually makes any store stand down.
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.
thats because when they are testing the cpus, they test them before certain things are setup, they test them with a certain amount of cache for example, if it passes it can be sold for more money if it fails they have to reduce the cache until its stable, either making it a xeon, p4 or celeron. (depending on the cache and bus speeds they set) since all 3 cpus use the same core and very similar pin setups they can test these before the final product is done.

Display size in real units is not a matter of "UI hack", it's a system setting in X on Linux. Any recent Qt or Gtk linux GUI application should respect it at the toolkit level (provided you're not doing anything really wierd like deliberately not using "new" (antialiased etc.) Xft font rendering) - if they get it wrong, it's a bug, so report it!
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.
Also, in GIMP (2.2) Display settings, I note that "Get Monitor Resolution" has a "from windowing system" option, you don't need to calibrate the GIMP separately from the system wide setting if you've got the system-wide setting right!
Additionally, most modern chips are still partially functional with some sections disabled. Budget chip lines can be created by disabling failed parts of chips and selling them with a reduced feature set. Examples of this include the 486SX (a 486DX with a failed FPU), some Celerons (Pentia with half of the cache disabled), and the Athlon 64 (an Opteron with only one working HT bus).
Or that a 3200 XP is just a really good 1900 XP?
I haven't been following AMD's line closely for over a year, but it's certainly possible, although the wrong way around. I would not be surprised if a 1900 XP is simply a 3200 XP that was not stable at the full clock speed. This was certainly true of the 1-1.4GHz Athlons.

Oh, when you said "gimp" I assumed linux, slipped my mind there was a windows port.
Windows 2000 and XP, however, do also have system-wide DPI settings. As is usual in windows, they're in a bit of a strange place to my linux brain, but they do exist - they're associated with font settings, not monitor settings. You know when you select "small" or "large" fonts in Windows Display Properties? They actually change the screen dpi between 75 and 96 dpi or something like that (might be 96 and 120, I don't have a windows box anymore), the _actual font size_ is a separate parameter set in the GUI theme!
If you select "Custom" (or mayber "Other") instead of small / large , you actually get a little ruler you can calibrate the DPI of your screen on!
So, in summary:
Use the display "font size" setting in windows to customise the system-wide DPI. Obviously. Not.
Then use the font preferences for the different GUI elements (i.e. what font in the titlebar etc. to set the natural-unit point sizes for the fonts you want on-screen.)
You are a little off.
You go to Display properties->Advanced->General
There you can change the DPI of your screen. It is very logical. In Gnome, however, the DPI is under font setting - which isn't really logical as DPI is a physical feature of the monitor hardware. It applies to anything that you want to display, not only fonts.
" since all 3 cpus use the same core"
Not correct. Although Celerons are busted P4s, the Xeon is a different CPU.
The P4 (currently "Northwood" or "Prescott") cores and the Xeon cores (currently "Gallatin" or "Prestonia") are different. They have the same basic design (Northwood ~ Gellatin, Prescott ~ Prestonia) but the Xeon has additional L3 cache and a different layout. The P4 "Extreme Edition" is based on the Xeon.
Also note that the Opteron ("SledgeHammer") and Athlon 64 ("ClawHammer"/"Newcastle"/"Winchester") are different cores.
I bought a Dell Inspiron with the WUXGA screen (1920x1200) and was suprised to find not a single dead or stuck pixel. I found one that was dimmer than the rest (and on the edge at that), but was plesently suprised to find a nearly perfect screen. Judging by the returns to Dell (i.e. what shows up in their outlet), there aren't many bad panels showing up on these high resolution panels. I don't think the notebook panel makers are sharing their secrets with the desktop guys. How else to explain all the 19" LCD's with 1280x1024 resolutions?
