Hello, All!

Having the issue mentioned above, at 30hz and 60hz. Basically, any time I switch over to 4k.  Connecting to an R9 290.  I have a DP to HDMI adapter that works at 30hz, and the HDMI outputs at 30hz.

White sticker on the line reads:

FW: 7.1E

Changed the bit depth to 8, and am now able to get 4k @ 30hz.  No luck with 60hz yet, though…. Still poking…

Hi Starboyk, thank you for joining our forum! 

Unfortunately the Vizio TV’s are picky eaters when it comes to our CAC-1070 adapters. Fortunately we do have quite some users who have been busy trouble shooting and it seems this forum user was able to get his Vizio M43-C1 working. Please check this thread for info:

Thanks! received an email from support with the firmware update.  Did as directed; works smashingly now.
