Further evidence has suggested that the Nintendo Switch OLED model’s updated dock can support 4K/60fps, even though the Switch hardware currently doesn’t.
Last week it was reported that the updated Switch hardware comes with a new HDMI 2.0 cable (compared to the original’s 1.4 lead), which means it could theoretically transfer a 4K signal at 60 frames per second with HDR applied.
The discovery would suggest that the Switch OLED dock definitely has new hardware inside to support HDMI 2.0 and upward. “It should also be noted that the Tegra X1 featured in the Switch does in fact support 4K60fps output over HDMI2.0,” Kawlun notes.
Curiously, Nintendo has also recently added an “update dock firmware” function specifically for the OLED dock. This could potentially indicate that Nintendo could decide to add a 4K option in future, similarly to how it recently added Bluetooth audio support via an update.
