[visionlist] LCD Monitors suitable with suitable temporal response

All LCD panels, particularly the fast panels used in gaming displays, in
addition to uniformity problems, have serious temporal nonlinearities.
Our pragmatic approach has been to pick one (Samsung R2233RZ, no longer
available), thoroughly characterize it (all gray-to-gray transitions)
and keep experiments within the narrow linear range.
We tested one OLED TV, LG 55EC930. Spatial and temporal response are
stellar but could not drive it past 75 Hz and could not disable the
automatic dimming features to prevent burn-ins. Dell has plans for an 4K
OLED monitor, which they stopped because of burn-ins.
