It is a rather large disparity...
so many calibration profiles for the LG thread, yet a total of 20 posts for Samsung's calibration thread.
Yes, looking at the posts seems like Samsung Panels are great out of the box.
I have an LG panel and after a few days of tweaking the profile, I got it to where I am perfectly happy with the colors and performance.
Its the shimmering text (text only) while scrolling thats driving me nuts.
