Nintendo Switch: 4K and 60 Hz support may come to the OLED Model via a dock firmware update
The Nintendo Switch OLED Model may have been a bit of a letdown, but @KawlunDram has noticed a few pointers that have been missed until now. Based on their research, they have discovered that the new Switch Dock, HEG-007, has an HDMI 2.0-capable chip.
Specifically, the chip is the Realtek RTD2172N KBDQH1, a USB Type-C to HDMI converter. Incidentally, Nintendo includes a 4K/60 Hz HDMI cable in Switch OLED Model boxes, an unnecessary accessory if the device only peaked at 1080p.
Additionally, the Switch's Tegra X1 SoC supports 4K/60 Hz via HDMI 2.0. In our opinion, it would make no sense for Nintendo to release a 4K-capable Switch only to cap it at 1080p. Consequently, people have theorised that the inclusion of a 4K/60 Hz HDMI converter could be for 4K video streaming.
Unfortunately, Nintendo has not included any references to 4K support in the Switch's OS. However, it has recently added an 'Update Dock' feature in Settings that Nintendo is yet to use. Hence, Nintendo could add features to the HEG-007 dock at some stage, such as enabling 4K/60 Hz output for some content.
