SOURCE: Shadowing on right side of TV

i had the same problem. it was the small mirriors (light tunnel)only one or two of the four mirriors have the tape. mine only had one taped. one of the other ones came loose blocking the light passing thru the tunnel on that side. you can fix this yourself (if like mine you are out of warranty) but it does involve taking some of it apart to get to the tunnel. then remove it and glue or epoxy it in place. mine has lasted for two months so can go to and put in samsung shadow on screen it discribes the repair(alot of pages, it happens alot)

Try clicking the auto adjust button on the screen. If this doesn't work it may be in demo mode, so click the fENGINEbutton on the monitor and make sure it is selected on the normal setting.

Try also resetting the your monitor back to factory settings from the forteManager software that comes with it. It's under Options, Restore. I had a similar problem and this fixed it for mine.

Screen Half darker

It sounds like your backlight isn't working properly. LCD screens have backlights that illuminate the colors produced upon their surfaces, so that you can easily see the screen without an external light source. In your case, it sounds like your backlights either aren't cailbrated, are damaged, or were produced unevenly.

There is most likely not a fix for this, though most all LCD screens have some form of light distortion. My own LCD screen is slightly brighter around the edges, where the backlights are located, but this is only noticeable when displaying a completely black screen.

I believe that the board/chip which controls the LCD is defective. I have never seen this but this is the only thing that I know that would explain your problem. Probably going to need a tech to look at it to verify.
