The dock which ships with the Switch OLED is capable of outputting 4K 60fps, it has been suggested.
The claim comes from YouTuber
Nintendo Prime, who managed to get hold of a console ahead of its official release on Friday. When comparing the revised dock with the original one, it was found that not only does the dock itself have the HDMI 2.0 controller required for 4K output, but the cable it ships with is also 4K-ready.
By way of comparison, the HDMI controller inside the original dock adheres to the older HDMI 1.4 standard, as is the cable it ships with and is not capable of 4K 60fps.
Nintendo Prime also points out that while there's an ARM-based chip on the dock's motherboard, it does not have the power required to upscale a 1080p image to 4K, so any upscaling would need to be handled by a more powerful Switch console.
