Can you explain what you mean by these statements? I'm noticing something similar when comparing my IPS to the VA, but I'm not sure how to articulate it. Why would VA produce a more flat surface versus IPS? I thought it was the low haze unit I'm primarily comparing the VA against, but then I noticed something similar with the matte IPS.I already said different LCD technologies require different eye focus. This was especially obvious to me when switching from VA to IPS. In my case this didn't result in any eye strain however, just in me looking at panel differently and I actually like IPS presentation more even despite there being nothing tangible to focus at or perhaps exactly for that reason.
If some people as it seems are less flexible in these kind of things then it might as well be that VA panels are better for them. I must admit that VA are in some way more like flat surface in that eyes have at least surface to focus at, unlike IPS which seems to be more like watching transparent mosaic of colored glass.
