Investigate whether rotating the screens is required #5

Last meeting we discussed the possibility of avoiding moving the physical screens, and instead using a configuration that would cover the entire visual field of the animal, e.g. four orthogonal screens or a surround screen, either curved LCD or projection.

@ederancz did you have a chance to check what was the original concern with a static screen configuration? If it were possible to use a static screen configuration this would significantly simplify the engineering but also will affect the choice of slip-ring and other parts of the project so it would be great to confirm if we could go ahead with this option as soon as possible.

the only real concern was the ability to generate and display VR content as apparently available solutions required “VR goggles” approach vs “VR CAVE”. If BonVision operates as CAVE, then stationary screens are perfect.

And here is my previous postdocs' take on this:

Well we chose to run the 5 screen setup under Windows - and that turned out to be not straightforward at all. While basic display worked, the various programs had trouble working out the fact that there were screens related to different graphics cards/chipsets and drivers, and which one to use when. 4 screens only on one card should work. But operability will be the question.

Regarding the video card, just a note that I have an NVIDIA Quadro RTX5000 available, in case it fits the bill. By no means do we have to use this one though.

Closing issue as I believe we are settled on the screen surround approach.
