Monitor Fades out with certain programs and websites not all.

Connect your laptop to an external monitor and switch to monitor. If the external monitor shows the desktop, then the complaint is in the lcd/led display unit means the screen. Replace the screen. If the external monitor also shows the complaint, then it is normally due the mch(media controller hub) . It comes as separate card unit in some models and onboard for some other models.Only an experienced technician can solve that issue. In some rare cases it is due to a corrupted BIOS. Reply if this helped you.

If you can try hooking it to another computer, if the problem persists then it's probably the monitor. If it works correctly then a new video card may be in order.

Have you verified that the problem is indeed your monitor and not the video card on your PC? i would start by connecting the monitor to a laptop or another PC to verify that the same issue occurs no matter what the source. Once you've verified that, you're likely dealing with a monitor that requires repair or replacement. Hopefully it's under warranty. Hope this helps a bit.

Simplest solution first; check your cables. If the connections are good, but it still doesn't work, try your monitor with another computer. If it works, you need to update the drivers on your computer. If it doesn't, the problem is with the monitor. If your computer needs drivers from LG for the monitor, you need access to another computer (or another monitor to go online). Go to LG's website and look for SUPPORT. Download drivers for your monitor specific to your operating system (Windows, Mac OSX, etc.) and install.

Connect the monitor to a different desktop/laptop, and see if it still "fades". If it does, the monitor is the problem.

If it fades linearly, it is probably the high voltage inverter for the backlight fluorescent lamp. Generally, the lamp dies over time with some flickering of it first.
That inverter is normally on a small, separate board and once the unit is open, it is easy to locate and replace.

its the fault of R.A.M. , change the R.A.M. and check it out.
