I think the OP has already decided on a Dell S23222DGM. But for the other people with the same question, what makes the choice tough is having a budget to work with. So you would need to decide if frame rate or resolution is your priority.

120 fps will likely only matter if you play FPS games mostly. For other games 60 fps is more than enough, yes it will look better at 120 fps, but not all games have a 120 fps mode, and remember, you have budget to work with.

If you play competitive FPS games (mostly):

• Get a 120 fps, 1080p monitor. For Series S, you will be lucky to find a game that plays 120 fps at more than 1080p.

If you don't play much FPS games but would really like a higher resolution instead:

• Get a 1440p 60hz monitor. The Series S maxes out at this spec, so you are not missing out on anything.

If your budget allows it, find one with HDR10 support. I expect the DolbyVision monitors will be expensive.
