HI all,
My system has 2 monitors, GetMonitorAttribute() can work normally when first use, but after second monitor unplug, using GetMonitorAttribute() will get error value. I am working in CVI 2017 / Win7.
Below link says this is a bug and fixed in CVI 2015.

But I still have the same situation, do I need send other commands after unplug second monitor?
Thanks for help.
