Since a 15 inch LCD display contains 2,359,296 pixels, a 19 inch LCD display contains 3,932,160 pixels, and a 24 inch LCD display contains 6,912,000 pixels, having a few “bad” pixels is not considered a defect. It is rare for a monitor to ship with or develop bad pixels. If or when a bad pixel occurs, it is not an indication that more will occur. It is usually a solitary incident. A pixel may be Stuck On or Stuck Off. (Bright or Dim) as shown in the examples below:
The minimum number of defective pixels we allow before we will replace an in warranty monitor is as follows:
- For a 15″ Monitor – 7 or more bad pixels
- For 17″ and 19″ Monitors -10 or more bad pixels
- For 21″ – 24″ Monitors – 17 or more bad pixels.
If your monitor keeps displaying the Blue Screen of Death (BSOD), you should run a self-test on the monitor to see if the problem is the monitor itself or some other portion of your computer or DVD player (or CCTV camera, DVR).
To run a self test, follow these steps:
- Turn off both your computer(DVR) and the monitor.
- Unplug the video cable from the back of the computer.
- Turn on the monitor. Depending on your monitor, one of the Check Signal Cable figures shown below appears.Note : While in the Self-Test mode, the monitor’s LED power indicator remains green and the Check Signal Cable figure moves around on the screen.
If no Check Signal Cable figure appears, there is a problem with your monitor. If you see the Check Signal figure, and one of the colored squares within it (as shown above) does not appear, there is a problem with your monitor. If you see the “Check Signal Cable” figures as they appear above, your monitor is functioning properly.
The BSOD problem you are having is probably being caused by your video controller, video card, video drivers, or computer system. If you did not see a ¡®Check Signal Cable¡¯ figure or a colored square did not appear, your monitor needs servicing.
