Recently, a rising concern among gamers has surfaced regarding the Steam Deck's capability to output 4K at 120Hz. The issue has sparked debates on forums, highlighting the limitations some users face when connecting their devices to high-end displays.

The Context Behind 4K Expectations

A Steam Deck owner expressed frustration in forums after connecting their device to an LG C1 TV via a USB-C hub. While they achieved 1080p at 120Hz, the jump to 4K only yielded 30Hz.

User Insights on Graphics Capabilities

Three central themes emerged from community discussions:

  1. Connectivity Challenges: Users emphasized the need to check the specifications of the HDMI/DisplayPort cables and hubs used. One comment pointed out, "You gotta check what version of HDMI/DP the hub supports."

  2. Hardware Limitations: Responses indicated that the Steam Deck might not effectively push 4K 120Hz, with some stating, "The dock might not support 4K 120Hz or 60Hz."

  3. Realistic Expectations: Several users redirected focus from 4K aspirations, suggesting that even 1080p at 120Hz is an achievement for handheld devices. โ€œHandheld devices my manโ€ฆ 4K 120? Thatโ€™s a dream,โ€ one user commented.

Highlighted Concerns and Opinions
