Tomshardware has made an inquiry about the warranty policies of several LCD manufacturers. Although there is an iso standard which explains when an LCD screen should be replaced due to dead pixels, it looks like there are just a few manufacturers who use this standard.
They contacted several (if not most) of them, and discovered that there are some major differences about when warranty is appliable:
“Their answers, when they come, are simply staggering. While some say they replace the panel, no questions asked, at the first sign of a dead pixel (Lite On), others wait until there are ten before acting!
Even more worrisome is the response from IdealVision, the leading French dealer for CTX, Neovo and Relisys panels: a point-blank refusal to release this information. This, however, was their second stance, as they had previously told us some Relisys monitors were not replaced before they had seventeen defective pixels. Could this be why they clammed up?”
