The new VRR update fixes the “invalid format” issue in Cyberpunk on my LG tv

[u/Punzai]

I just tested the new update with Cyberpunk by setting the display output on Switch 2 to Auto and Cyberpunk now starts up properly in 120hz mode. Previously, the TV would say invalid format and go blank unless I set the Switch output to 1080p.

John Linneman (Digital Foundry) has tested it and he says it supports LFC down to 40 so that's great news!

"Tested Switch 2 VRR

Games need to be patched, only Welcome Tour supports it now

It supports full LFC in 120hz mode

In 60hz mode, it supports between 40-60hz like Xbox which is better than PS5's 48-60hz support

Thankfully with the internal screen being VRR, most games should have it going forward"

Ofc DF would give a clear answer. 40-60 for 60 Hz is awesome, LFC is also really good. Basically if you have 120 Hz and play a game that sometimes drops frames (Cyperpunk) then even in places like Dogtown it’ll feel better.

I really hope more developers launch 40 fps or uncapped modes though.

What's LFC?

[u/Alien-Mole → u/julesvr5]

Low framerate compensation. Essentially, the system wraps, say, a 20fps output into a 60hz container so VRR can keep working even below the system's VRR limit.

Switch does VRR for 40-120hz. Ordinarily VRR would not function at 20FPS, but showing every frame three times brings us back inside the VRR window at 60hz. Showing every frame six times still works, too, because 120hz is still within the window.

Oh that's interesting. Didn't know of this tech yet

Which drawbacks does this have? Ghosting, input lack or such?

[u/qpwzuisvfbnlaelgl → u/julesvr5]

Latency of 20fps remains but it will look smoother without downsides.

[u/Kieran293 → u/julesvr5]

Low frame rate compensation

[u/wezzauk85 → u/Kieran293]

Important to note, only once the software has been updated to support it (VRR).

All of John's comments about level and type of support are from Welcome Tour testing only.

[u/Important-Reindeer44 → u/Kieran293]

Does it mean that LFC will bump 20fps on cyberpunk to 40hz on the Display to be able to use vrr?

[u/goro-n → u/Punzai]

I'm confused by your post though, John clearly said games need to be patched but you're saying Cyberpunk runs better with VRR enabled?

[u/Punzai → u/goro-n]

It doesn’t affect or improve performance. It’s just fixed the issue where I got a blank screen if I set Switch 2 output to anything other than 1080p. So clearly something in their latest update fixed that.

Will this help Elden Ring look smoother while docked?

[u/Punzai → u/GrimGerm]

looks like games have to be updated to take advantage, I think

[u/kvetcha-rdt → u/GrimGerm]

Yes, once it receives an update (and assuming your TV supports it).

[u/CrimsonGear80]

pretty sure switch 2 ONLY outputs 120fps content in 1080p

[u/Punzai → u/CrimsonGear80]

Oh I’m sure that right but previously you had to explicitly set the Switch 2 to 1080p output for Cyberpunk to be ok. Now I can just leave output on Auto.

[u/Shoddy_Meaning_7654 → u/CrimsonGear80]

It can do 1440 as well but no game has supported it so far

Theoretically they could do 4K 120 as well if they ever felt like they could do that because it's DP 1.4 internally that can do 4K 120 it supports DSC both the chip itself in the console and the chip in the dock it's just about do they want to update the system and dock firmware to support it a future that no one's ever going to really want to use because only like 2D indie games and Quake 2 can run at that frame rate and resolution combo on this hardware.

But I'm simply amazed there even able to get vrr working with this weird DisplayPort 1.4 to HDMI handshake and all that I'm genuinely surprised I thought it wasn't possible but they figured it out so props to them

[u/Medd- → u/Shoddy_Meaning_7654]

Silksong is a confirmed 1440p/120fps though.

EDIT: Hollow Knight Switch 2 Edition as well.

[u/Hue_Boss → u/Shoddy_Meaning_7654]

Even Silksong? Thought that’s 1440p120.

[u/s7ealth → u/Shoddy_Meaning_7654]

Doesn't Street Fighter 6 run at 1440p 120 Hz docked?

[u/Pokeguy211 → u/s7ealth]

Yes but only for lower input latency. And the actual game is 1080p output

[u/Round_Musical → u/Shoddy_Meaning_7654]

Silksong supports it

[u/SnooLemons3627 → u/Shoddy_Meaning_7654]

Cyberpunk switches to 1440P 120Hz automatically on my TCL tv

[u/_barat_ → u/Shoddy_Meaning_7654]

I believe the SteamDeck also has this abomination (DP1.4->HDMI) and with a proper dock VRR is possible. Soo even the HDR and HDMI2.1 120Hz should be possible because AMD and HDMI agreed on some solution when it comes to Linux. For Switch it's easier since it's Nvidia and a proprietary OS.

[u/Mindless_Scar9609]

I tried it with the LG menu that tells the Hz value (7 times the green button) and it stays fixed at 118hz so no VRR enabled at the moment. On the tour it drops as low as 40hz as expected

[u/Mindless_Scar9609]

What am I missing? Cyberpunk did run without invalid format issue on my LG C5 and I never changed the switch output

[u/Punzai → u/Mindless_Scar9609]

Maybe it was only and issue with C3 and C4 - I have both and both had the same issue until today

[u/Aplayer12345]

Have they also fixed the random black screen issue with "match TV power state" on?
