As shared by Nintendo Life, YouTuber Nintendo Prime has recently got their hands on the Nintendo Switch OLED a few days before its official launch. In a video discussing the console’s components, Nintendo Prime has noticed a few clues in the console’s HDMI cable that hints towards potential 4K output.

According to Nintendo Prime, the cable that the Nintendo Switch OLED ships with is a HDMI 2.0 (which is required for 4K output), and the cable is also 4K ready. In the same video, it is revealed that the new Switch console features an ARM-based chip on the dock’s motherboard. However, it isn’t able to upscale to 4K and would need a more powerful console to do so.
