Ah so the Switch 2 dock has an extra fan? I didn't know that.

Still, what happens if you connect a Switch 2 to a 1080p display? I assume it would render at 1080p, because rendering at 4K and downscaling for output would be too wasteful. Switch 1 even has a setting for that, allowing you to choose between 480p, 720p, and 1080p.

It renders at 1080p and the dock doesn't get as hot.

Note that the cooling fan inside the dock is for cooling the dock and not the Switch 2 itself. The Switch 2 has its own fan for that.

So while not everyone docks the Switch 2 to a 4K display, the Switch 2 dock must support that.

DP -> HDMI conversion hardware is pretty intense. I haven't owned a device that does this and doesn't at least get warm.

> DP -> HDMI conversion hardware is pretty intense.

It can be, but it doesn't have to be. DisplayPort is mostly a superset of HDMI, with different voltage levels. Going from HDMI to DisplayPort is much harder than going from DisplayPort to HDMI, though the hardware to do this is apparently much cheaper than it used to be, which is nice to see.

DisplayPort to HDMI only requires level shifting, as I understand it. I'm sure someone will correct me if they see this and I'm wrong.

		No, it requires active protocol conversion, https://www.exhibitedge.com/how-to-connect-a-displayport-dev... But also yes, most display port implementations also speak hdmi and can get away with simple converters

		This is not true, DisplayPort and HDMI is not compatible, but the dedicated converter chips are quite efficient at their job. One is present inside every USB-C to HDMI cable, dongle or dock, as there is no such thing as USB-C HDMI alt-mode. Heck, even laptop HDMI ports are usually implemented through a DP converter. You might be thinking of DisplayPort++, which is a special port supporting both DisplayPort and HDMI, allowing passive adapters. This is not available in the USB-C DisplayPort AltMode.

It's not. Every USB-C to HDMI cable in existence is a DisplayPort alt-mode cable with a DP to HDMI converter at the end. They don't require active cooling, even if they get a little warm.
