found my problem, after install resolution was set at 2160p at 24 and when I switched to 1080p at 60 everything was normal. I know my tv will do 2160 at 60 but I did not have the option. Is this due to the problems with the converter chip?

Have you done the firmware upgrade for the LSPCon chip? You'll need to do it in Windows unfortunately... There should be no issues with the LSPcon after upgrage to 1.66.

Yes I installed windows 1st and updated the bios and the firmware to 1.66

This is a vizio E43u-D2 and according to the specs, it should do 2160 at 60

HDMI 1 Tech Spec600MHz pixel clock rate:
2160p@60fps, 4:4:4, 8-bit
2160p@60fps, 4:2:2, 12-bit
2160p@60fps, 4:2:0, 12-bit

but when I use the xrandr command I get this
