Published specification
What is true of this model and changes how you fix it
These are the properties that decide which procedure applies. Each is read from the manufacturer’s own published figures for this model, not carried over from a sibling that shares its retail name.
- Type — Switch OLED dock accessory (HEG-007)
- This is the DOCK accessory from the Switch OLED, not a console — it carries power and video (HDMI) to the TV and adds a wired LAN (Ethernet) port. It has no controller, storage, account or game functions of its own, so those symptoms do not apply; it only outputs the docked console to a TV.
- Video is 1080p
- Being an original-generation Switch dock, it outputs up to 1080p to the TV — it does not add 4K (that is the Switch 2 dock). A 'no 4K' expectation here is the hardware, not a fault.
- Wired LAN
- Its built-in Ethernet port gives the docked Switch a wired connection — useful for online stability, and a reason to prefer it over older docks.

Questions that only have an answer for the Nintendo Switch OLED dock
Each answer below uses this model’s own published figures. The same question asked about a different model in the line has a different answer, which is why it is answered here rather than on a general page.
My Switch shows no picture on the TV through the OLED dock.+
Work the dock, not the console: confirm the dock's AC adapter (the high-wattage official one) is in the dock's power port, the HDMI cable runs from the dock to the TV, and the TV is on that HDMI input. Seat the console fully so it clicks in. A green light on the dock and the console charging confirm power. If it still shows nothing, try the HDMI cable/port directly, since the dock only passes the signal — it outputs up to 1080p, not 4K.
