What does "USB-C with DisplayPort 1.4 Alt-mode support; up to 8K @60Hz or 4K @120Hz, USB 3.2 Gen 2" mean?

Under the Specifications page of the Steam Deck, it is indicated under "Expansion" -> "External connectivity for controllers & displays", the following:

USB-C with DisplayPort 1.4 Alt-mode support; up to 8K @60Hz or 4K @120Hz, USB 3.2 Gen 2

But under the "Display" -> "Resolution", it says "1280 x 800px (16:10 aspect ratio)".

What does these all mean? Can I possibly play a game natively in QHD 2560 X 1440p resolution at 120 Hz and use Adaptive Gsync if the Steam Deck is connected to a TV/Monitor that supports it?

I think it means we can play games natively at 1280x600 @ 60 hz and then possibly at higher res with Steam Dock when hooked up to a 4K or 8K display. It could also mean we need a gaming pc to act as streaming host to enjoy 8K @ 60 hz or 4K @ 120 hz gaming through Steam Streaming.

I found this older article interesting for seeing what is needed for a game to run at 4K @ 120 hz though not sure what the newer GPUs are capable of

Steam Deck uses similar hardware to latest gen consoles which support 4K @ 120 hz gaming natively but Steam Deck is much smaller format so really do not think we can expect games to run at that high res and refresh rate - I think we need host pc or cloud gaming vm that is capable of running games at 4K @ 120 hz to stream them to Steam Deck in Dock mode hooked up to a suitable display. Though Steam Deck is compared to last gen Xbone and PS4 consoles in performance so really do think a streaming host is needed for 8K@60 or 4K@120 gaming in Dock mode but have admit your guess is as good as mine. I too am interested in learning more about how gamers can enjoy 8K @ 60 hz or 4K @ 120 hz gaming through Steam Deck + Steam Dock.

USB-C supports video passthrough. Those are the specs of the maximum resolution you could run using a USB-C to DP or USB-C to HDMI adapter. That doesn't mean you could play games at 8k on a 8k tv at a good fps. But you could display an 8k screen on that 8k tv.

I still have the silent hope for thunderbolt support. With that, the device would be absolutely awesome. A decent integrated GPU which could easily handle the resolution of the integrated display and the option for an external GPU for the big screen.

However, since AMD devices with thunderbolt are quite rare, I expect to get only USB-C which is still fine. Hopefully the multi-monitor mode of my Dell WD-15 dock is supported. I haven't had the chance to test this with an AMD GPU, but with an Intel GPU that works fine in Linux and a bit buggy in Windows (but hey, that's what you'd expect from Microsoft).

You all talk about 8k and 4k, when in reality you all are already lost your eye sight because of long term gaming and cant tell the difference unless you push your greasy face on the monitor to the point where you see pixel.

Stop giving a ♥♥♥♥ about resolutions and refresh rates. This will save you so much money.
And in the end, when you game you dont actually care about that stuff unless you watch too many of LMG videos and now cant accept that 1080p @60Hz is still pretty good experience.

the dp supports those resolutions and refresh rates, but no way the mobile igpu can handle gaming at those specs
it might be able to stream at those rates tho

For now, I will actually already be happy if I can play at 2K resolution @ 90-144Hz on the TV while game is being streamed through a similar device like the Steam Link. A bonus would be to also enable Adaptive Gsync if the TV and streaming device will support it. That feature helps the game run a little faster and has better visual quality than without it. It would be great to be able to take advantage of those features that some of us already have in our set up.

If the Steam Deck and/or Dock can help with that, its value would be higher and I would probably just have to get them as an upgrade to my two aging Steam Link hardware.

Well, it's amd, so that means freesync / "gsync compatible". I think some of the newer gsync modules might support freesync as well. If your display is older, then the gsync module probably does not support freesync mode.

So when you say "Adaptive gsync, do you mean true gsync, or freesync variant?

"Freesync variant" I guess. Thus those folks with Nvidia cards has higher chances of also being able to utilize the tech. That would be in tune with Valve's open design of the Steam Deck & Dock. :-)
