I want to buy a new 3440x1440 LG display for working with Unreal Engine. I already have a 1080P monitor and GTX 960 card. But I read that GTX 960 does not support 1440 and I also want to keep the other monitor for dual display. Now, I am thinking of buying an AMD Radeon RX5700 which can handle the 1440 display and is also less expensive compared to NVIDIA models. But I do not want to sell my GTX 960 card. So, can I keep the Radeon and 960 both and connect the Radeon to the 1440 display and the 960 to the 1080P display and make an extended screen?
