It seems that the video cards in some of our systems have problems displaying subliminal stimuli. We have some nVidia TNT2 based cards that are listed in the manual as having problems. We're looking to upgrade those cards and I'm looking at the nVidia GeForce2 MX400 based cards from Jaton (Mfgr part # DFORCE2MX-64DDRTV). Are there any problems with those?
