Confirm the model first

Which units this covers, and how to tell yours is one of them

Every answer below is scoped to these model identifiers. A neighbouring model in the same line can use a different part, a different reset sequence or a different radio, so matching the identifier before following a procedure is the step that decides whether the rest of the page applies to you.

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.

Model — Switch OLED (HEG-001): The premium original-generation Switch with a 7-inch OLED screen (richer handheld picture), 64GB storage, a wired-LAN dock, and better speakers/stand. It docks to a TV at up to 1080p and plays handheld/tabletop — the same games as other original Switch models, just a nicer screen.
Storage — microSD expandable: 64GB internal (double the older models) plus a microSD card slot for more games — storage-full is solved with a microSD card.
Display — OLED is handheld only: The OLED benefit applies to the built-in screen; docked to a TV it outputs the same 1080p as other original Switches. It is not 4K (that is the Switch 2).

Exact questions

Questions that only have an answer for the Nintendo Switch OLED Model

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 OLED looks great handheld but the same on TV — is that right?+

Yes — the OLED screen only improves the handheld picture; when docked, the Switch OLED outputs the same up-to-1080p image as the standard Switch, because docking uses the TV's panel, not the OLED. So identical TV picture between an OLED and a standard Switch is expected. For a higher-resolution docked image (4K) you would need the Switch 2.

Structured depth, not empty permutations
