i can do, but could do with an idea of how best to recreate the issue? the guy there on HF suggests it's gone when switching to the uniformity mode as well
It's quite easy if you have a solid background colour, with say purple (maybe not too dark or light) and open something like a browser window to a site that has a lot of white in it.
Another one is to open the lagom.nl
gamma page. This is not white, but has still produced the anomaly for me across the vertical gamma images - I noticed it on my current background which has a very cloudy sky, so a lot of grey.
I noticed the guy said it went away with smart uniformity and your ICC profile, but I was hoping to correct it without using that preset - I have not tried your profile yet, but found that smart uniformity crushes blacks quite severely so avoided it for now.
Plus, this may present itself on other inputs where I won't be able to use a profile, such as console.
I have not done huge amounts of testing across different inputs, etc yet.
Like I said, I can live with it for now, but would like to establish if it's fault or settings issue, etc, so I will know what to go to Philips with down the line.
I can't say I have noticed it in games, nor the couple of movies I have tried.
It apepars to happen only with solid vertical lines of high contrast or some such, so may only appear in desktop use.
It also seems directly proportional to the height of the contrasted area - so a short contrast area vertically won't show it, but a large one will - can be tested by shrinking the size of a browser window.
Edit: wow, that was long-winded! Sorry
