I have taken a few photos to show you my improvement on the yellow blob issue before and after VSUS change.
I have also noticed that the blobs reduce if you leave the white screen on for a period. It is like they fill out and slowely become whiter. Of course they come straight back after a darker screen is shown, so this doesnt really help, but is interesting. You can also see on my right hand blob it has quite a bit of blue around the bottom of it, and also some green. Quite ugly.
Vsus changed to high
This is much better with the blobs all but gone. The photo makes it look like the white has quite a bit of tint in it. This is just the photo and looks much whiter in reality. I can notice like some others have said a little magenta around the very outside edges. This is not evident in regular viewing anymore as it was before, unless a commercial comes up on the TV with an all white screen with limited text.
I have still not been able to fix the dark screen issue with light blobs Here is a photo in professional picture mode 1 where the problem mainly is:
It is very hard to get a nightime shot, but here is an attempt. you can see the light blobs in the same zones as the yellow ones.In the middle of this image I have displayed a 1% grey test pattern as a comparison. You can see that the blobs and the 1% grey are much the same MLL.The funny thing is as you leave this dark screen image up the blobs get worse over time. This is the complete opposite to the yellow blobs fading with time. IIt happens over the first few seconds.
These two issues must be related. If I can change voltage to improve the yellow blobs I wonder how I can change a different one to improve the dark screen ones. Maybe the secret lies in the other VAD trim pot.
The good thing is I can watch my DIY calibrated THX cinema with the improved yellow blobs with far better blacks than Pro1 and less of this light blob issue. My main reason for wanting to improve the light blobs on dark screen now is they show up quite badly in 3D mode for some reason.
