I don't get motion, sea, or VR sick, but if you put a 16:9 27" 144Hz TN panel in front of me, I'll start yawning and drooling in a matter of minutes. If I ignore that, I'll get too nauseous to work until I lay down for bit or take a long walk outside. The cause seems to be twofold. At a reasonable viewing distance, the strain caused by having to constantly focus my eyes differently between the corners and the center begins to give me a raging headache. This isn't true for <22" or >34" panels, though, so it's a function of my lens plasticity. The second factor is related to the panel technology. Scrolling on TN panels makes me feel the same as I do when I watch certain Hulu shows and poorly shot 3D films. Those incorporate subtle DOF that causes eye strain and discomfort on subjects in a scene your brain thinks you should be able to focus on (like trying to read the artistically blurred signage on a door in Avatar 3D). Resisting it makes me almost immediately sick to my stomach. With TN panels, knowing that I should be able to focus on the content as it scrolls yet just barely not being able to read it due to blur and poor panel characteristics (eg- backlight) is highly nauseating. I've used HFR displays with IPS/(M)VA panels for almost a decade with no issue. At work I use a 13" MBP, and at home I use a 39" 4K 120Hz VA panel. I'm actually stuck right now deciding between 13" models of MB Air and Chromebooks because I know deep down I really just want something with a 4:3 or 5:4 display, which would either mean an iPad Pro or modded ThinkPad.

  My guess would be that I place larger displays far enough away that my eyes aren't constantly refocusing. A better answer may be that I also benefit from displays below a certain proportion of my field of view. I try to work in open areas where I can relax my eyes periodically by looking out of windows, and being able to see around the screen is important for that.
