The flickering video issue is noticed on all GPUs irrespective of how powerful it is, or even if the game runs on a high FPS.

Moreover, this issue is especially prevalent on the dual monitors with 144hz and 60hz refresh rate setups.

In this post, we have listed 7 ways to get rid of video lags on the second monitor. Read to know more.
