Yes, I understand there's no way to turn on and off the dithering in Intel graphics. Is that correct?
Also:
Regarding VA:
"The static picture quality was good, with a bright, clear image. However, any animation played would leave 'trail' of ghost images behind it as a type of 'smearing'. This has the affect of a very unpleasant blurring of images during scrolling a web-page, watching video, or playing a game.
And the speakers are quiet, sound bad, and the volume is buried in a menu. Even when maximized the speakers emit very little sound, and the quality is low. This is the audio quality I would expect from a speaker purchased at a dollar store. That is not an exaggeration.
I would avoid this product and spend an additional $50 on something of a higher quality. This monitor is terrible for nearly any modern purpose. I tend to do a lot of work on the command line in Linux, and while the screen is static most of the time, when scrolling text, even at this task, it is unbearable."
This is another clue about why VA could be more comfortable. The other display types are more designed for movement. The slowness of VA probably is directly related to what about it makes it more comfortable for extended viewing.
