Dual View Issues

[RasmusDC]

i really don´t get this..

 

i have the following hardware

 

Sony XC85 4K tv with HDMI2.0 and 4K 4:4:4 support (RGB), DEL 2715Q monitor (4K also) and a 1080TI Asus Rog...

Used to run my european KS8005 (American KS9000) as sim rig screen without a hitch in this setup, but now the fun begins..

 

If i use the 4K SONY as a single display and run 444 or RGB 4K 60hz, then i get a grey screen, or if i reboot, a "login" where it seems to be loggin in then the screen flickers, and i loops for ever...  or it locks in a grey screen where i can see a mouse cursor and that is it.

 

If i run it in DUAL view (not spanning that does not work, Dual as same image on each screen), then i can run 4K on both screens without an issue.. (so cable should be good enough it is a 7.5 meter cable with full support for 4K 444 think it is 18gbit, since cheaper cables did fail on me)

 

i can run 1080p single screen on the Sony without an issue, but cannot even run 4k 30hz, or 4K 60hz 420 it gives me the same issues.

 

the Sony runs currently the HDMI port as Enchanced..

 

the setup works perfectly with the KS8005 from samsung..

 

not the issue is, that i am scrapping the 4K Dell 2715Q screen for a 1440p 144hz screen, so that kills my possibility of running 4k on the Sony, which does suck, for simulator.

 

i tried reinstalling, that did not work. i am really at a loss here.

right now it is running dualview 3840x2160 60hz RGB, the instance i just remove the tickmark from the DELL screen, and actually just lets the Sony keeps it settings then i am fucked
