Is the Mac Studio compatable with SAMSUNG 49" Odyssey Neo G9 Series G95NA 4K UHD Curved Gaming Monitor

So let me understand if possible. Mac Studio M1 cannot get the full 240hz but an M2 Ultra Studio can get full resolution and 240hz?

• You can connect M2 studio with ONE HDMI Certified Ultra "48g" cable and expect to get a guaranteed 120 Hz, and if you get lucky, even higher.

• You can connect as TWO half-screens using one direct cable AND one Thunderbolt-to-HDMI adapter/cable and expect to get what you asked for, 5K at 240 Hz. It really is seamless provided the display supports Picture-By-Picture (a cousin of Picture-in-Picture), which your display supports. On the Mac, Setup looks like this with TWO Equal half-displays side-by-side. it will be treated as ONE wide display.

--------

There are no DisplayPort to HDMI 2.1 adapters that do not get burn your skin off hot and fail very quickly. HDMI uses higher voltages, and it throws too much heat.

For HDMI:

M2 studio introduced in 2023 (M2 or better in all models) feature an expanded version of HDMI, which produces HDMI 2.1 directly. Good thing, because you can't reliably make HDMI 2.1 using an adapter -- the adapters get 'burn your skin off' HOT and burn out rapidly. But you can make slower, less-demanding HDMI versions with adapters from ThunderBolt.

HDMI 2.1 is rated for up to 4K at 240 Hz on a standard HDMI display. 5K at 120Hz is possible if the display has implemented Display Stream Compression, which is likely, but not specified. There are no HDMI standard specs for 'top half of a 5 K display' as implemented in that model.

--------

Since the display has TWO HDMI inputs. you could also connect a direct HDMI AND an adapted HDMI, where each cable brings in a left or right 'half-display' worth of data, and use Picture-in-Picture feature in the display to re-assemble the complete picture. On the Mac, the Arrange pane in displays preferences supports this, and it works seamlessly.

only in certain cases:

5120 by 1440 means you will be constrained by requirements for a 5K display, but the data display will be like the top half of a 5K display only.

The data rate required (as high as 32.4 G bits/sec) EXCEEDS the maximum 20 G bits/sec data rate available over some USB-C ports (PROVIDED the USB-C port supports that data rate, which the Mac studios USB-C-only ports do NOT). So no adapters from USB-C to DisplayPort 1.4 will suffice to service that display at its full resolution.

The Mac Studio M2 and later model introduced in 2023 (NOT older models) features a HDMI 2.1 output which can support that display directly using HDMI 2.1, PROVIDED you are using TOP spec cables, certified Ultra speed "48G".

For displayPort:

Data rates of 4K at 240Hz are attainable with Display Stream Compression.

Data rates of 5K are attainable up to 180 Hz with Displays Stream Compression. To attain full 240 Hz on 'full size' 5K display, you could have to use compression AND compromise on color representation.

I have laid out what is certain can be accomplished, using several different connection methods to several different models of Mac Studio.

If you need additional information, please ask a more pointed question.

I see now. So basically what the M1 Ultra studio gives me now via one thunderbolt to usb-c 120hz I will not get any better using one connection for full screen even with the new hdmi 2.1 connection. Just not possible unless I split screens.

Direct HDMI:

M1 studio can get 4K at 60 Hz on its built-in HDMI 2.0 port.

M2 and later can use their expanded HDMI 2.1 to get up to 5K at 120 Hz using Display Stream Compression.

if you split the screen into TWO, each is a 2K display, and each can run at 240 Hz refresh rate directly, even in your M1 Mac Studio.

The Mac has supported Extended Desktop across multiple displays since at least 1987. The feature works with every well-behaved Mac application. When you scroll, both screen move together as one, "the right way". It's NOT a hack.

So I’m confused. The M2 basically cannot do it and can only do what the M1 does which is 120hz ?

the pointed question is using a display port to hdmi 2.1 connection, will I get the 240hz refresh rate on am M2 Ultra Mac Studio? Not attainable?

I did not know this. Basically it will be one seamless screen although split into two. I will try when I get home. This would

be great. I wanna try and see this.

<<. although split into two. >>

after setup, you will not know or care about that.

One HDMI to usb-c and the other HDMI to HDMI, correct?

yes.

It is possible it will configure the two displays automatically, but I just don't know.

You may have to set one or the other or both to be "2K" displays.
