I've heard that on Linux, at least, spatiotemporal dithering is disabled and only spatial dithering is used. You can see the Intel Graphics mailing list post here about eyestrain, quoted below:
I'm really confused about what could be causing this. Resolutions don't matter; you always get the eyestrain. My first thought was temporal dithering (or spatiotemporal dithering), but my reading of the intel driver source is that the kernel drivers have disabled ST dithering in favor of spatial dithering.
I wrote to the gentlemen who made that post, it took him about 3 months to get used to the display, but after that, he was fine. He did not get any diagnosis of a BVD nor pursued vision therapy nor prism glasses.
But, I wrote to another gentlemen who replied on that Intel eyestrain thread. He wound up going to an orthoptist and he had to get eye exercises which resolved the issues. Just another report of vision therapy working! He adds:
...my conclusion is that there was indeed something different with that machine. However, the muscles of my eyes should have been able to change positions in order to be able to adapt myself to that difference. Therefore, the problem was myself and not the machine.
I should add that the ditherig
program is open source and available here.
