Re: [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.

How about OLED screens?

I have been looking into these, and wonder about people’s
experience with these for vision research.

I am also
curious about noise effects on electrophysiological recordings.

Best, Martin

I was wondering when this would come up. 

These folks did a nice eval/review a few years back.

Also,
see this paper on temporal/motion issues.

Phillip,
Since you’re at Berkeley I was going to suggest that you talk with
Marty Banks but I see that you already work together. Are there specific
issues re: time/motion that you’re concerned about that aren’t
addressed in these papers or are you just polling the community for
broader info?

Hello,

I’m wondering if there are alternatives to CRTs and the
ViewPixx3D ($12,000 each) displays that can be used when fast response
times are required for temporally varying stimuli. From this paper http://ift.tt/2llIYuM
it seems that certain gaming monitors may be approaching the required
quality level, are there any specific high framerate gaming panels that
have come out in the last two years that approach parity with CRTs? 

Thanks,

Phillip Guan
