DVI is the port with screws for locking down the output. If you want full resolution on your TV you need high speed HDMI 2.0 cable. [URL] Only the HDMI 2.0 port supports the 3120 x 2160 60hz With combination of adapters you can convert all of the ports to HDMI  Then you can use 3 monitors all the same 1920 x 1080 aka Full HD. Up to 1080P  1920 x 1080 you can convert to video only DVI to HDMI. Display port is NOT bi directonal. DVI Male to HDMI Female You may need 2 of these [URL] You will need one of these.

A year ago I purchased an Alienware Aurora Ryzen Edition R10 with an NVIDIA GeForce RTX 2060 SUPER.  The video card has 2 outputs, one DVI and one HDMI.  I have two VIZIO 4K HDR Smart TV | V405-H19 attached to each output, one HDMI to HDMI and one DVI to HDMI.  I have them setup as extended multiple displays in Windows at 1920x1080.  HOWEVER... 1) these are NOT the recommended settings of the software, and 2) everytime I shutdown and restart, or, just turn off and on the monitors I "play monitor roulette", I never know what the settings will be or the display will look like.  Is there a fix??? Like DVI to an adaptor for multiple displays???
