This is a 4K 60Hz machine through and through. Impressive for sure, but not geared towards high refresh rate. Some titles manage 120Hz but in lower resolutions and with reduced settings. The Series X is also an amazing machine, but for a desktop-based study environment it’s not a good fit. For your living room 4K TV or gaming projector, definitely. The Xbox Series X showcases games in a very stable formula, that of 4K 60Hz in high or ultra settings. It’s nigh indistinguishable from PC versions of games other than the PC offering unlocked frames, if you have a powerful enough GPU. We’re very doubtful the Series X will go beyond 120Hz, as that would mean diverting the focus to lower resolutions. Sure, with 12TFLOPS of GPU power the Series X can effortlessly do 165Hz or more in 1080p and 1440p, but that’s not something Microsoft appears interested in.
The bottom line is that if you prefer 1080p high refresh rate to 4K 60Hz, then the Series S is the console you want. Both Series X and PS5 are very firmly 4K 60Hz HDR ultra setting devices and do not prioritize going beyond 60Hz, as the prime directive for both is to avoid sacrificing resolution and visual quality. The Series S is free from those constraints, and has no problem letting loose in 900p 165Hz if developers allow it to do so.
