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
