Graphics Cards

I have 2 LG monitors in Freesync @ 3420X 1414

a samsung 4K TV 43" Hooked up to HDMI I use to be able to run it at 4800 x 2120

now I cant take it past 1920X1080  all screens will start going black and on again 

I think the HDMI ports is bad I switch cables and no joy

and some times I do even get an option to increase the screen res on the 4K tv

Windows 10 pro

AMD 3800X 32G of Ram

X570 Aorus Xtreame Motherborad

anyone have problems with the HDMI port ?

Thanks

You say that at some time the TV was able to display properly but now it is not able to do so. What changes happened to the system from when things worked until now when things are no longer working?

Also, what version of Adrenalin are you using? Did Adrenalin update between things working and now? Did you check on Adrenalin to make sure the TV is showing the correct parameters/settings in Adrenalin? Open Adrenalin and go to the Display tab. There are many settings in there that can be determine how the GPU handles the display(s).

Running the latest software and drivers nothing had changed. 

Not at home atm so cant verify the settings
