I had two samsung d8000 tvs and they both had severe cases of it along with flashlighting.(picture was fantastic)
I then moved on to sony and bought an ex723 which still had the DSE problem...but the picture was not as good as the d8000... so i returned that set..
now i have had a xbr909 for about a month and it has fantastic picture, zero blooming when viewing straight on.....no flashlighting but it still has minor DSE!!
question is there a fix? its very minor on the set....but it pisses me off that a 3000+ tv has these issues....
has anyone fixed thier dse?
1. Banding is a special case of DSE
2. DSE is the perception of the actual luminosity uniformity distribution across the panel's display area.
3. Any and all LCM layers and casings can contribute to the resultant uniformity issues of the composite set.
If you agree with the above definition of DSE, there is a fix, that I have seen in the patent literature:
Map the actual luminosity uniformity levels at each pixel, and correct the display stream. (LG Display)
Practically speaking, we can consider the following cases:
Case 1. Some models are architecturally prone to DSE/Banding - not much you can do about it.
Case 2. Some models have a varying amount of DSE - try to find a unit with a minimal amount of DSE.
Tweaking or calibrating your set may result in a reduction of discernible DSE (by minimizing the observable nonuniformity).
Some people are not sensistive to DSE, due to variances in perceptual acuity (including, but not limited to motion tracking and image stabilization mechanisms) -http://www.perceptionweb.com/ecvp/ecvp07.pdf
