Nintendo is telling third-party builders to focus on 4K decision, sources inform Bloomberg, hinting the brand new Change mannequin revision might output to 4K decision. How will this be dealt with? We now have a couple of concepts.

Stories point out Nintendo is making a brand new upgraded Change console that targets larger decision. We initially interpreted that the brand new Change would have an upgraded handheld show, however it seems as if the upgraded mannequin will goal 4K decision output for UHDTVs.
There’s a number of methods Nintendo might do that, however let’s check out the most affordable and most cost-effective answer: Upgrading the Change dock’s built-in video output converter and utilizing NVIDIA’s AI upscaling tech.
Nintendo has stated repeatedly it would not care about higher-end specs. Nintendo’s most important ethos facilities round enjoyable being extra necessary than energy. What’s much more necessary is making a revenue on hardware. To try this, Nintendo has to give attention to low-cost manufacturing.
It is doable the brand new Change mannequin coming in 2021 might merely be a 2019 Change revision with an upgraded dock. Present customers might purchase the brand new dock which might enable improved efficiency on 4K TV units. This manner, Nintendo would not should work with NVIDIA to make one more Tegra revision (or presumably adapt its Pascal SoCs) and fully re-design the Change.
If a 4K-based Change have been certainly coming, it’d possible be a devoted console. The warmth generated from 4K gaming (even upscaled) would prepare dinner the Change’s present setup. In actual fact, that is a giant cause why the Change’s GPU speeds are halved to 302MHz in handheld mode; to make sure the console would not overheat.
So how would this work?
New Change dock and AI-powered 4K upscaling
To grasp how this might work, we’ve got to take a more in-depth take a look at the present Change dock.
The Change makes use of DisplayPort Alternate mode over USB Kind-C for video output, which is facilitated through a particular converter chip, the Megachips STDP2550 Mobility DisplayPort (MyDP) to HDMI Converter.
DP Alternate Mode permits USB-C cords to transmit USB three.1 knowledge, energy, and A/V indicators by means of one wire.
If you dock your Change, the video sign is distributed by means of the USB-C connector through the DP over USB-C (Mobility DisplayPort) protocol.
The STDP2550 then converts that video sign into HDMI 1.four video out sign which is transmitted by means of the HDMI wire and to a HDTV. The dock is mainly an adapter that allows you to play Change video games on a display.
This specific chip is proscribed to HDMI 1.four and solely helps 1080p 60Hz.
This is extra data on the STDP2550:
The STDP2550 makes use of MegaChips’ newest era DisplayPort receiver know-how that helps a single AV stream at HBR2 pace, an information charge of 5.four Gbps per lane. Additionally, the HDMI transmitter in STDP2550 relies on superior high-speed TMDS know-how supporting hyperlink charge as much as 2.97 Gbps and the stereo 3D codecs.
It may ship 1080p 60 Hz video with a shade depth of 24 bits per pixel and audio as much as Eight-channel at 192 Kb pattern charge from a MyDP supply to HDMI TV. This system complies with the HDCP 1.three content material safety scheme with an embedded key possibility for safe transmission of premium digital AV content material. It may additionally act as an HDCP repeater for the downstream sink when utilized in a dongle software.
- DisplayPort to HDMI bridge for TVs and projectors
- Audio-video accent (dongle) for Notebooks, Good telephones/Tablets
The STDP2550 chip would not obtain the total USB-C Alternate Mode capabilities, although, which technically helps as much as 4K decision at 60Hz, full with HDR, and HDCP 2.2.
Megachips additionally has a 4K chip which converts DisplayPort 1.4a video indicators to HDMI 2.zero, permitting for 4K 60Hz video output on UHD screens.
The chips is known as the MCDP2900 DisplayPort 1.4a-to-HDMI 2.0b Converter:
The MCDP2900 is a complicated DisplayPort1.4a-to-HDMI2.0b protocol converter focused for TVs, Recreation consoles and different client gear in addition to for cell PC, pill accent purposes. This system is an lively protocol converter with HDCP1.x/ HDCP2.x repeater supporting HDR video high quality for deep shade media content material playback. This system is appropriate for video sources corresponding to BD gamers, Recreation consoles and STBs for streaming 4K HDR protected content material over HDMI2.0b interface. It’s also a seemly answer for AV sinks and department gadgets corresponding to TVs, Displays, docking stations and dongles with DP enter or USB Kind-C enter supporting DP Alt mode.
The MCDP2900 helps UHD video codecs, resolutions as excessive as 4096x 2160 @ 60 Hz in RGB/YCbCr video shade codecs with a shade depth of 16 bpc so long as it matches inside the DP and HDMI hyperlink bandwidth. This system helps pixel encoding conversion from RGB or YCbCr444 to YCbCr422/420 perform and due to this fact HDR video with deep shade as much as 12bpc at 4Kp60Hz is supported by means of the conversion of RGB/YCbCr444 over DP hyperlink with horizontal enlargement to CEA timings to YCbCr420 on the HDMI TX output.
This may very well be the chip Nintendo makes use of on this theoretical new dock.
The thought could be to make use of the converter chip to output 4K decision. However there is a lacking piece right here: Upscaling.
Fortunately the Tegra X1 and Tegra X1+ each help NVIDIA’s AI-upscaling, which might drastically enhance visuals, together with boosted decision, larger distinction, and rather more element.
One of the best half is you would not all the time should be on-line to make the most of the AI upscaling.
You’d merely join the Change on-line, play a sport, and NVIDIA’s AI server banks would decide the right picture upscaling algorithm for that exact sport/decision. Then that algorithm could be downloaded to the firmware
Nintendo might additionally pack in an inner upscaler into the dock and even an HDMI wire fairly than depend on an UHDTV’s inner upscaler. Textures would not be upgraded to native 4K as a result of the Change could not deal with it. They’d simply be up to date to look higher in 4096x2160p.
This could be like Marseille’s mCable, which improves the Change’s 1080p visuals on 4K shows. That is admittedly costly, however Nintendo might possible discover a viable mass-production chip possibility.
Moreover, the Tegra X1 chip, which is what the bottom 2017 Change and 2019 Change revision are each primarily based on (newer mannequin makes use of 16nm TegraX1+ refresh with extra energy effectivity), was constructed with 4K in thoughts and helps HDMI 2.zero output.
