Rather strangely my stereo set uses the following Option "AllowDFPStereo" "on"
I look forward to hearing how you get on as all my past experience with stereo and LCD screens was less than positive Hope this helps Mike -----Original Message----- From: CCP4 bulletin board on behalf of James M. Vergis Sent: Fri 22/06/2007 17:10 To: CCP4BB@JISCMAIL.AC.UK Subject: Re: [ccp4bb] Flat Screen and Stereo I don't know if this will help but the NVIDIA readme says it should be a BOOLEAN after ALLOWDFPSTEREO. You have: Option "AllowDFPStereo" "1" Change to:Option "AllowDFPStereo" "true" Hope that helps. I'd be curious as to how an LCD works for stereo.
