Cab-FL-1159-250 doesn't work .
I bought the product http://www.primecables.com/p-337582-cab-fl-1159-250-thunderbolt-mini-displayport-to-hdmi-vga-adapter-primecables?_ga=1.81066911.969993683.1468064075so that I could work with two external monitors with my macbook pro. the monitor connected via VGA does not display anything when the monitor with HDMI is connected. Both monitors are brand new. Each monitor has been tested independently with the macbook pro and works correctly when connected both HDMI to minidisplay port and VGA to minidisplay port. The issue is not with the monitor or macbook pro.
Thanks for contacting shopper+family .
It indicates attention "This adapter contains 2 chipsets and support both digital ,and analog signal .But the HDMI and VGA port can not be used simultaneously "
