gaming makes a few of these issues really pop out, some may be applicable to screens in general, esp small ones.
1)FOV - a very common fix for nausea in first person shooters is increasing the field of vision to > 100degrees. Supposedly a narrow FOV makes your brain think it's been poisoned.
2) high contrast colors. a lot of newer games are bringing a high-contrast look (less dark/grunge)- nice look, but consistently causes people problems in the forums
3) weapon 'bob'. things move around at different rates, this can sometimes be disabled. seems similar to the screen overlay (3d look) issue.
