Does Thunderbolt 5 mean the mbp can now support 7680x2160 at 120hz?

I've had my eye on the Samsung Odyssey Neo G9 (the 57-inch mini LED monitor), but I know people have faced issues getting the full resolution at 120Hz through a single Thunderbolt cable. Many have reported needing to use the HDMI 2.1 port to achieve 7680x2160 at 120Hz.

Now that the new MacBook Pros support Thunderbolt 5, does this mean I should be able to get the full 7680x2160 resolution at 120Hz through just a Thunderbolt connection? If so, that would be a game-changer for me.

Would it support the full res at 120hz with the lid open too?

Also, does anyone have recommendations for a Thunderbolt 5 dock that would support 7680x2160 at 120Hz?

It's possible you would even get the full 240hz if you can find a cable that will pass TB5 to DP2.1, since this monitor is 240hz capable over DP2.1. These things often need to be tested to be sure because the handoff between cables and adapters can get screwy, but the bandwidth is definitely there.

I'm just hoping my Samsung CRG9 5120x1440 @ 120hz is going to be supported! These oddball aspect ratios aren't listed in the Apple Tech specs. The monitor only has HDMI 2.0 so that means 60hz... but DP 1.4 supports the 120Hz... if MacOS will drive it.

Specs page says the Max will do DP2.1, but it also says displays are limited to 8K @60, or 4K @240.

I will really be disaapointed if a 5120x1440 at 120 wont be supported..is it not supported with thunderbolt 4?

Do you mean hdmi 2.1? Or DP through a dock?

• One external display supported at 8K resolution at 60Hz or one external display at 4K resolution at 240Hz over HDMI

M4 Max

• Simultaneously supports full native resolution on the built-in display at 1 billion colours and:
• Up to four external displays: Up to three external displays with 6K resolution at 60Hz over Thunderbolt and one external display with up to 4K resolution at 144Hz over HDMI
• Up to three external displays: Up to two external displays with 6K resolution at 60Hz over Thunderbolt and one external display with up to 8K resolution at 60Hz or one external display with 4K resolution at 240Hz over HDMI

If anybody happen to have gotten their hands on a new MBP (m4+) and happens to have the 57inch g9 and also has a thunderbolt 5 dock, let us know the resolution/frame rate you are getting.

Greatly appreciated
