Will a 1440p Monitor Affect Gaming Performance With a 1080p Second Screen?

Asked by MellowCedar42
I currently use a 1080p monitor and want to add a 1440p display as my main gaming monitor, while keeping the 1080p screen as a second monitor. My planned system has a Radeon 9060 XT 16GB, an Intel Core i5-14400F, and 32GB of RAM. I'd mainly use the second screen for manga, Discord, music, or occasionally looking up a guide while the game is paused. For anyone using a similar setup, does the second monitor cause noticeable FPS drops or make it harder to stay above 60 FPS at 1440p?

That setup should work well. Iโ€™m using the same GPU with a 1440p 180Hz main display and a 1080p 75Hz secondary monitor, and the second screen doesnโ€™t affect performance in normal use. Youโ€™d mainly notice a difference if both screens are running demanding programs and youโ€™re already maxing out the CPU, GPU, or RAM.

MellowCedar42: Thatโ€™s reassuring. What 1440p monitor model are you using?

A second monitor usually has almost no noticeable impact, especially when itโ€™s only displaying a browser, Discord, or music. Performance may change slightly if you run another GPU-heavy application on it, play video with hardware acceleration, or use something like an animated wallpaper, but normal desktop use should be fine.

MellowCedar42: So gaming at 1440p should be fine if I keep the second screen to manga, Discord, music, or occasional guide searches while the game is paused?
