Question about Dell UltraSharp U4025QW

Yes, a 14" MacBook M2 Pro can actually support a refresh rate of 120 Hz. The M2 Pro can reach up to 240 Hz via Thunderbolt, while it can reach a maximum of 120 Hz via HDMI 2.1. In contrast, previous models such as the M1 (including Pro and Max) could only output up to 60 Hz via Thunderbolt and HDMI 2.0. For the best results and additional benefits such as Power Delivery, USB hub functionality and 2.5Gb LAN, you should connect the display via Thunderbolt :)
