I'm assuming there is something wrong with the tv and I should swap it out tomorrow? I didn't notice this until I started up my PS3 which has a dark theme, and I then tried out a few movies that had a lot of dark scenes and I can't unsee it now.
My first reaction is that it is clouding but it could be the backlight/brightness/contrast is too high for the given source/input. Did you watch the TV on various input sources before changing the calibration settings? Was it clouding out of the box?
The LCDTVBuyinguide calibrations were not tuned to a PS3. Every source is different and every input can be calibrated for the source. Makes it a real problem when using a DVD Calibration utility and trying to port those settings to the STB input.
Does the effect occur on ALL input sources or just the PS3? If it is just the PS3 as the input source then connect it to a different HDMI input and see if it is just that HDMI input or doe the effect follow the PS3.
If you followed the LcdTvBuying guide instructions then those calibration settings are saved as ISF "Expert" 1 for a specific input. The TV's Picture calibration settings are saved independently for each input/source. If you did not save the Whitepoint settings to "All Inputs" then those settings are per Input/sources as well. Switch your TV's Picture Mode back to Vivid, Standard or Cinematic. Then do a RESET of the picture settings (this may not reset the whitepoint adjustments but you can just change it from 20pt to 2pt). Do you still have the same CLOUDING
effect? If so then you may have a hardware problem.
Next go to HERE
. Scroll down to the WIKI section and download the USB_SCR_TEST,ZIP file. This will test for dead pixels by displaying screens of solid pure colors including black. If you still have clouding then you may have a problem.
Your picture with a pure black, red. green image being displayed should be fairly uniform with maybe some "edge bleeding" a known "problem" or fact with edge lit LED screens. They all have it to some degree,
Also be aware that the Magic Remote cursor creates a "brighter" area around it so turn the cursor off when examining the screen for clouding.
I have used the LCDTVBuyingGuide calibration settings and thus far have am pretty happy with it but I am still tweaking.....
