It seems some misinterpretations are floating around regarding the next Switch model. Since I was asked to clarify, here's what we know so far about it: 1) A new retail model is definitely being worked on for release. There have been references to it since firmware 10.0.0;

3) "Aula" will feature an improved display of some sort and it bundles a dp2hdmi chip from Realtek (likely RTD2173 or from the same family). Communication with this chip is done by the "nvservices" system module using new ioctls for sending/getting panel messages via DPAUX;

4) The new display requires special handling in code, suggestive of OLED/MiniLED technology, and is tied to a new manufacturer;

5) The SoC is still Mariko/T214/T210B01/TegraX1+; 6) DRAM is now being produced with 10nm process, but no new sizes or types can be observed. This means "Aula" will keep the usual 4GB LPDDR4X.

Considering the information we've extracted and observed, we speculate this new dp2hdmi chip is designed for upscaling HDMI output to 4K. This is further corroborated by changes in the HDCP DRM ("nvhost_tsec" firmware inside "nvservices") and by looking at RTD2173 as example.

It's still unclear how the output signal will be generated (new dock?), but the evidence suggests the dp2hdmi chip lives *inside* the new display and not in an external PCB.
