Hello,
We have recently had a SMART GX065 V3 installed into one of our classrooms and it appears to be really flaky with our Dell WD19s Dock in terms of the HDMI connection. When we connect a HDMI cable directly to the laptop it works as expected however when connecting the laptop to the dock and running the HDMI through the dock the board flickers on and off the display, We have gotten the SMART GX65 series before but it appears to be an older model not the V3 but just the GX series and this has worked fine through the dock.
We can fix this temporary by going into the display settings within windows and changing the board refresh rate from 30hz to 60HZ while on the android screen on the board and then flicking back to HDMI however as soon as the board turns off this setting gets reset and the next teacher will have to update these settings, also the board works fine off a 30hz refresh rate when connected directly to the laptop via just an HDMI cable.
We have tried with both a 130W and 180W Dell Dock but get similar results.
We have updated the Laptops BIOS and Display Drivers, updated the firmware on the docks as well as checking the GX Smartboards firmware is up to date
Is this just because the V3 of the SMART GX boards will not work smoothly with the Dell Docks when previous GX Boards had or is there something I am missing.
Any Advice would be appreciated.
