Below, crops of photographs of my WD-73640 screen, as it displays 1080p HDMI from my PC. (No matter that it's from my PC: this issue occurs with all HDMI inputs and Component, regardless of the source AND REGARDLESS OF TV SETTINGS, INCLUDING COLOR, but will be hidden by turning TV sharpness up.)
To begin, below is the image as it appears normally on the TV - blurred and full of artifacts.If you can't see the differences at this size, click on the images for a large size.
The only difference between the above photograph and the one below is a change in color in the source image before being sent to the TV: a change in the input signal. (Just as one could do in the color settings of their Blu-Ray player.)No skin tones, no problems
: A slight shift out of reds/skin tones, into less natural greens, and original sharpness is restored, and nearly all artifacts go away:
The PC dialog box in the top left corner shows the color changes made - in terms of "vibrance" (related to saturation) (top slider) and hue (bottom bar), where 50% "vibrance" and 0 degrees hue rotation is normal.
Now, this is just one scene, with a certain range of skin tones.
Below, let's see what a slightly different skin tone results in, by lowering saturation just a tad - oh my, even more blurry!No color, no problems
: Remove all color information, and correct sharpness is restored, and all defects disappear:
Similarly, increasing input saturation also results in better sharpness, as shown below:But notice how the "extreme case" phenomenon, mishandling of pure reds near pure whites, is still visible in the pajamas.
Added 1/28/2012:Test Video Demonstrating Color Decoding Defect in Mitsubishi 2011 DLPsI have made the ultimate test video for demonstrating & testing for the color decoding defect that plagues 2011 Mitsubishi DLP sets.
It is available as an ISO burnable to DVD, a 1080p AVCHD DVD, playable in a Blu-Ray player.
(Like this site's AVCHD version of the AVSHD 709, for those who have done that.)
THIS SHOWS SOME REALLY CRAZY ARTIFACTS if you have the defect.
It shows just how extremely crazy things can get with just the right content.
Even those who know they have the defect should watch this on their Mits to realize how much their picture quality is being degraded.
It'll also be helpful in explaining the defect to a service technician. You're welcome.The 419MB AVCHD DVD ISO file is available here:https://www.onlinefilefolder.com/3savmOPw6gdBGe
(that is the same as clicking on the image above)
Mirror here, but the 1st link should be the fastest: http://dl.dropbox.com/u/1842312/2011...DLP%20Test.iso
(both will probably be very slow)After downloading the ISO, Windows Vista/7 users can burn it to DVD by simply double-clicking it and following the wizard.
Everyone else, (well, except Mac users), I recommend freeware "ISO Recorder":http://isorecorder.alexfeinman.com/isorecorder.htm
-------------------------------Streaming Video for your PC
If you have a PC connected to your DLP, or are impatient with the download,
you can watch a more compressed version in my usual gallery:
(unless you play the 'Full HD' version, and your DLP is set to 1920x1080, you won't get the same effect - some defects, but nothing like the ISO )
Also in that gallery, after the video, are good stills to play as Slideshow.
