Re: [COOT] 120hz LCDs and coot stereo
Just get a $300 Zalman LCD monitor and use coot with that. No special hardware required and it is OS independent. I'm using it also as my primary monitor as I type this.

My question is can i use one of these new 120hz LCD monitors with the above setup for coot. Basically just switch out the crt for the LCD. Has anyone tried this? I am aware that these monitors with a non-quadro nvidia card plus the nvidia emitter/glasses setup will not work with coot. But i think the reason is that the drivers for these non-quadro cards do not support true quad buffered stereo. -- Michael J Miley, PhD Research Assistant Professor Director, Biomolecular X-Ray Crystallography Facility University of North Carolina at Chapel Hill Dept of Pharmacology, CB# 7365 Medical School Building B, Room 124 mjmi...@email.unc.edu Office: 919-843-7174 Cell: 919-451-3593
Re: [COOT] [ccp4bb] [COOT] 120hz LCDs and coot stereo
I got the information from a supplier that there is a beta driver from nvidia that supports the 120Hz LCD with nvidia stereo glasses. I have not seen it myself but we have a demo scheduled in January. Alexander -Original Message- From: CCP4 bulletin board [mailto:ccp...@jiscmail.ac.uk] On Behalf Of David J. Schuller Sent: Thursday, December 17, 2009 6:19 PM To: ccp...@jiscmail.ac.uk Subject: Re: [ccp4bb] [COOT] 120hz LCDs and coot stereo My current understanding is that 1) The new 120Hz LCD monitors are not compatible with the old goggles. Something about the type of polarization used for the shuttering effect. So if you were going to try out one of the new 120Hz monitors (~ $400) you might also want to spend on the nVidia glasses and emitter kit (~ $200) 2) The 120 Hz LCDs are not supported under Linux drivers by nVidia at present. Whether it might actually work or not, I can't say. I am encouraged by the mention that the nVidia emitter can accept a signal from the mini-DIN stereo port on some Quadro cards. http://www.nvidia.com/object/quadro_pro_graphics_boards.html 3) As someone mentioned already, the Zalman LCD monitors, which are not 120Hz and do not require goggles, but have diminished resolution, are currently supported.

I tried to run it with the normal setup, quadro with emitter via DIN, nuVision glasses, Linux. Here's the problem: I have stereo in the top and the bottom but not in the middle of the screen. The image is stable (no flickering or moving of the part that shows stereo). It seems that I got the right refresh rate (any way to check that?), but I don't understand at all what's going on. Any clues? Jens That monitor appears on the supported displays list: http://www.nvidia.com/object/3D_Vision_Requirements.html So the problem could be one (or more) of two things: 1) The glasses may be incompatible. You could try it out with the nVidia glasses. 2) The Linux driver may not be working properly yet. BTW, I see that some 1920x1080 monitors are listed on the above page, and should be available in January or so. -- === You can't possibly be a scientist if you mind people thinking that you're a fool. - Wonko the Sane === David J.
