Isn't this one of the few specific technical specs Nintendo themselves released back on 4/2 after the Direct? I could've sworn it's been known to be 2.1 for some time by now.
Switch 2 dock output is HDMI 2.1 not 2.0

Are you connecting it straight to the TV?
I had to do that and while you cannot set that resolution, the game will switch to it if needed. Try the SF6 demo and then check with the remote controller code the HDMI info.

are there tests done with different docks to see what type of concerter chips have issues?
also, the Deck works with the Switch 2 dock (you of course need a female to male cable to get to the usb port)... has anyone tested connecting the Deck, through the Switch 2 dock and enable VRR?

Nintendo would need to do a firmware update to enable it.

VRR is disabled in the dock…not going to work probably, that's the whole point of a possible firmware upgrade in the dockare there tests done with different docks to see what type of concerter chips have issues?

, but the chipset is 100% capable of VRR.

The RTD2173 does not support VRR. For example the Intel Arc A770 uses it and does not support HDMI VRR. It only supports VESA adaptive sync. So the monitor/TV it connects to on HDMI needs to support VESA adaptive sync for VRR to work. If the RTD2175N is a rebrand it may have the same issue.

well, do we know this? did anyone test the dock with a Steam Deck for example?

The Switch 2 uses the RTD2175N-CG and yes, the RTD2173 supports VRR, some PS5 Slim have that chipset.

Going to ask a friend for a test. But probably is not going to work for obvious reasons.

Source? As far as I can find Sony uses a Panasonic chip.
It also contradicts Intels information:
Variable Refresh Rate (VRR) 'Not Supported' in Intel® Arc™ Control
Describes an issue with enabling VRR when connecting a VRR capable display through HDMI port.

Intel Arc A770 Review - Finally a Third Competitor
With the amazing-looking Intel Arc A770, the blue team is making a push to offer a capable mid-range graphics card product at affordable pricing. Intel is including a lot of modern tech like AV1 video encode, hardware-accelerated ray tracing units and more on their newest release.

it could be simply not supported on a software level on the console itself due to complications with the conversion.
for all we know the Dock will output VRR just fine with a source that supports it.
if I had a female to male USB-C cable handy I'd test it myself

I don't think it's a predecessor, although it could be. I think it more likely that the RTD2175N-CG is the RTD2173, but firmware/hardware-optimized for the Nintendo Switch 2 dock. The "-CG" is normally used by Realtek when the product is customized in some way. Since the RTD2173 is already a DisplayPort 1.4 to HDMI 2.1 adaptor, it makes more sense that they customized this chip for the Nintendo Switch 2 instead of developing a completely new chip that is already doing the same thing but with a few more bells and whistles.

Btw,
called it
Opening the package you see HDMI ULTRA HIGH SPEED on the included HDMI cable, that's 2.1 speed
If Nintendo would be too cheap for a chipset and choose HDMI 2.0 standard, you better believe they would also cheapen out and include an HDMI 2.0 cable which would just be HIGH SPEED like the Switch 1 OLED got.

That's probably on the Intel side but chip is capable of VRR via HDMI forum 2.1, this is from a old article:Source? As far as I can find Sony uses a Panasonic chip.

The RTD2173 converter will enable makers of notebooks, motherboards, docks, and other applications to build devices supporting next-gen HDMI output using current-generation graphics processors that only support DisplayPort 1.4 outputs. Meanwhile, such products will have certain peculiarities.
A number of modern high-end televisions featuring an 8K resolution are outfitted with HDMI ports that are technically ready to receive HDMI 2.1 signals, but are not marketed as HDMI 2.1 because they have not been certified by the HDMI Forum. Once the certification program for HDMI 2.1 is available, producers of Ultra-HD TVs can validate their devices and issue appropriate firmware updates to formally add HDMI 2.1 support. Makers of HDMI cables will release their Ultra High Speed HDMI (48G) cables around the same time.

Also this a proof that the certification is needed to enable HDMI 2.1 features, like HDMI 2.1 forum VRR.

I assumed this was something to do with firmware issues or certification, given then said it could do vrr docked up until very close to launch.
I still hope they add it in a future firmware update.

HDMI 2.1 support does not automatically mean HDMI VRR support. The two are not linked. eARC, ALLM, VRR are all optional. Even the article you linked has no mention of VRR.That's probably on the Intel side but chip is capable of VRR via HDMI forum 2.1, this is from a old article:

Yes VRR is a HDMI forum 2.1 feature… Doesn't need a special chip like the Nvidia Gsync or the AMD solution Freesync. (Obviously the chipset bandwidth need to be capable)

Ultra High Speed cables and Premium High Speed cables cost almost the same. UHS cables basically nearly erased premium high speed cables from the market. only for very long ones there's a tangible price difference.
they probably included a UHS cables because it was either the same price or in fact even cheaper, as I don't think anyone mass produces Premium High Speed cables that are shorter than 10m. they have become almost impossible to find in online stores from what I can tell.
also the fitting cable for the current capabilities would have been the aforementioned Premium High Speed standard, not a High Speed cable like the Switch 1 had.
Premium High Speed is 4k 60hz/1440p 120hz capable. High Speed is only 1080p 60hz and 4k 30hz

GerAlt-Right. Ciriously.
Yes, they refuse to allow AMD GPUs to use HDMI 2.1 due to the drivers being open source.

So where is VRR?

wow what? Didn't know about that. That's fucked up
Could they be being assholes because g-sync is behind at the display port gate? They can't mention that it is HDMI TM VRR or some stupid shit like that? Wouldn't surprise me to be honest.

Probably Nintendo is waiting for the HDMI forum certification to enable HDMI 2.1 features.

The device outputting to HDMI 2.1 still needs to support VRR. You can have something that is HDMI 2.1 certified and have zero VRR support as it is not a requirement of the 2.1 specification.Yes VRR is a HDMI forum 2.1 feature… Doesn't need a special chip like the Nvidia Gsync or the AMD solution Freesync.

HDMI 2.1 Compliance Certification Explained
The HDMI Licensing Admin says that new HDMI devices can be granted “HDMI 2.1 compliant” status even if they don’t support any of the features associated with the HDMI 2.1 standard. Confused? Read on.
www.audioholics.com
"All future devices with an HDMI 2.x connection will be tested for HDMI 2.1 compliance, even if they would have been considered HDMI 2.0 devices under the old system. These devices don't have to offer ANY of the new HDMI 2.1 features in order to pass HDMI 2.1 compliance testing. Also, the features of HDMI 2.0 are now considered a sub-set of HDMI 2.1. And since all of the newer HDMI 2.1 features have been considered "optional" from the start, a new TV can be labeled "HDMI 2.1 compliant" (and the manufacturer can stamp "HDMI 2.1" next to its HDMI ports), even if the TV has no FRL, no Dynamic HDR, no ALLM, no eARC, no VRR, no QMS, no QFT, no 4K 120Hz, and the ability to accept only 18 Gbps of bandwidth."
Now the lack of HDMI VRR support only applies to the RTD2173, the RTD2175N might very well have it.
