I have a dual monitor setup. Actually only one of them is a monitor of 144 Hz and the other is a 75 Hz TV. My monitor is connected directly to my GPU with a DVI-D Dual Link Cable and my TV is connected directed to the GPU as well with an HDMI Cable.
When I go to Radeon Additional Setting and go to Properties I see: Maximum reported refresh rate: 144 Hz. But when I go to Display settings (right click on desktop) --> Advanced display setting --> Display adapter properties --> Monitor, I see: Screen refresh rate: 60 Hertz.
And whenever I disconnect my HDMI Cable from my GPU the display adapter properties changes to Screen refresh rate: 144 Hertz.
So I would say that it's actually 60 Hz with the TV connected but I'm not sure. What would you say?
And if it is 60 Hz, how can I set it to display 144 Hz while still having my TV connected.
