A:AnswerI run a 980 TI and that card does not support either of what you are interested in. I am not unhappy with the results and I play Lost Ark, Diablo Immortal, large group WvW in GW2 etc. The cost of the monitor I would say would be well worth it but my cost was approx. 175.00. Not sure if that is any help. Good Luck!
A:Answerthere are 2 HDMI ports on this monitor, a 2.0 and a 1.2. You have to use the 2.0 port, then your console should support the 1440p/120 hz when you apply the correct settings.
A:AnswerIf you have any of the ECO modes selected except "Standard" all the other settings will be decided by the preset, so it greys them out.
The same thing happens with Color Temp if anything besides "User" is selected.
A:AnswerNot as far as I can tell. Besides the USB ports, all the ports are just for connecting the monitor to the computer and cannot send a signal to another monitor.
