Quote from Tums:
I would not buy a LCD monitor with less than 3 yrs warranty.
There are 3 basic components to a LCD monitor:
1. the liquid crystal panel -- making the panel is a very competitive business. There are only a handful of manufactures in the world who can make this at a profitable yield. They supply all the brand names you see on the shelf. You only have to watch out for dead pixels at the time of purchase. After that the panel seldom goes wrong.
2. The electronics -- this is the component that translates the signal from the graphic card and produces the image you see on the panel. Big brands would design their own, while smaller companies will OEM from the manufacturer. If this part goes wrong, it will go wrong on the thirteenth month.
3. Power module -- not the detached power supply that comes with the monitor. This is a module inside the monitor. If this goes wrong outside of warranty, take it to a TV repair shop. You can have it done at 1/3 the price.
