I have a new AMD Radeon RX580 8GB GDDR5 PCI-E 3.0 in a NEW computer.
Also, I do not do any gaming. I just wanted a faster up to date computer.
I have a HP Pavilion 27xi 27-inch Diagonal IPS LED Backlit Monitor (with resolution set to 1920 x 1080) & at first had it cabled via the DVI-D (Dual Link).
I have as a 2nd monitor that is an AOC 27V2H & had it cabled via HDMI.
When I went to Settings > Display, the AOC 27V2H was set as #1 & I can/could not get it to change.
Both monitors had background color & pictures. But the mouse would/will not go between the monitors.
The reason I got this card was because it should be able to use two (2) or even three (3) monitors. And I am thinking that the mouse should/would go between all monitors.
There are no instructions on how to do this.
When I had an EVGA GeForce GT 730 w/2GB in the NEW computer, the HP Pavilion 27xi & a AOC 2217V cabled via DVI-D (Dual Link), I had background color & pictures on both. I could take and open an Excel spreadsheet and it would be seen on both screens along with the mouse going between both. I could take a .txt file and put it on either monitor. I guess what I am saying is that I could use the two (2) monitors as one (1) big monitor.
Why can I not do this with the AMD Radeon RX580 8GB GDDR5 PCI-E 3.0???
How can I get the two (2) monitors to become one (1) big monitor using this card??
