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

Hi Phillip,What you can accept in terms of LCDs really depends on your requirements. If you just want a reliable 120 Hz update, then there are plenty of gaming-level LCD monitors that won’t drop frames. That’s the easy part of monitor characterisation though.Apart from the Display++ and ViewPixx (which are both excellent, and no I don’t have an interest in either company) we haven’t found any non-CRTs that meet our relatively simple requirements of:- Uniform luminance and contrast across the entire monitor surface, from a wide range of viewing angles- Rapid onset and offset, such that you get good luminance and contrast control for single frame stimuli.
If you’re just interested in reliable 120 Hz to present long-duration, non-moving stimuli, you have plenty of options. If you want static stimuli that are presented for 3+ frames, then you’re also reasonably safe. If you want moving stimuli, as long as you don’t care about contrast too much, then I think you’re also safe. If you care about contrast, then make sure your stimuli are small and always presented in a small part of the monitor so you don’t get viewing angle artefacts. At this stage, I don’t care about colourful things, so you’re on your own there! 

Basically, whatever monitor you get, you’ll still need to characterise its timing and luminance outputs (at a minimum). For my money, it’s worth the investment in a Display++ or a ViewPixx. nic

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 https://www.ncbi.nlm. 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?
