We have an experiment that works everywhere except on the computers in the lab. The error message we get is: "DirectRT can not determine your display's refresh rate which is critical for accurate timing. The cause of this problem is usually an outdated or disabled video driver, or disabled hardware acceleration in your video settings. Error #6. Overflow"
We have tried to update the video driver to the latest available, but is still didn't work. We also checked the dxdiag display-tab for errors but none were given. Next we checked the video settings which seemed ok, hardware acceleration has been set to full and the screen was set to 1024x768 in 32bit mode with a 60 and once with a 75Hz rate. We also tested with 1280x1024 mode, but all resulted in the above error message.
Thanks in advance,
Jane
