DETAILED DESCRIPTION
Under certain limited circumstances, some combinations of C/Ports, monitors, and Multi-Video Expanders
(MVX) may fail to meet ClearCube published specifications. The following combinations of C/Ports, moni-
tors, and Multi-Video Expanders are affected.
Case 1 – When in DVI mode, the monitor blinks on and off. These monitors are known to display this issue:
•
NEC LCD72VXM
•
Dell 1970FP
NOTE: Other monitors that were not tested may exhibit this behavior as well. ClearCube recommends
testing with all the brands and models of monitor planned for your deployment.
These combinations are affected:
•
800x600, 75 Hz
