Re: [visionlist] LCD Monitors suitable with suitable temporal response

Since a number of people have mentioned monitors that they have
tested and found to be good/bad, could remind people of the
i-Reviews section of i-Perception.

i-Reviews was originally created solely for reviews of web
resources (and can still be used for that) but we decided that
it should also be a useful place to send brief reviews of kit.

If you’ve collected data on a monitor, button box, or similar
device that you think would benefit others then please think
about sending a brief report on it as an i-Review. They are free
to publish, with peer-review but lighter touch than traditional
papers. There isn’t a formal limit on length but we are talking
brief. They are still indexed in the usual ways (pubmed etc) and
can be cited too.

It seems a shame that people are collecting all this useful
data but it isn’t being seen by others. And that people aren’t
taking advantage of this easy way to get a citable,
peer-reviewed manuscript for free!

So if you bought a piece of kit, or saw a web resource (youtube
video?) that you think could use a review then get in touch. You
can email me directly to discuss an idea if you aren’t sure.

best wishes,
Jon

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.

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
