Mac Studio (base spec M1 Max)
LG C2 42” OLED

I have a problem with this. I can’t for the life of me get 4k 60 10 bit connecting this from hdmi to hdmi. Apple website states this can do 4k 60 with a billion colours (ie 10 bit) when connecting to an external (non pro xdr) display.

Anybody have any ideas? Does connecting this with a usbc/thunderbolt 4 to hdmi 2.1 cable enable 4k 60 10 bit?

Yeah the cable was a hdmi 2.0 cable. Also tried a hdmi 2.1 cable and still the same. I can get 4k 60 no problem. It’s 8 bit only. I can’t get 4k 60 in 10 bit.

Pretty sure all M1 product, including Studio, is HDMI 2.0 only, not 2.1. I think 2.0 should be able to do 10-bit but I've not tried. If you can easily get a USB-C/TB cable/adapter to try that out it's worth a shot, cause yeah it should definitely be able to do 10-bit

It doesn’t say that. It says it can do 10 bit but only at 4:2:0 sub sampling. I’m fine with that but I don’t have the option to use that on this mac which goes against the hdmi standard.

I don't think macOS will send out 4:2:0 or 4:2:2. It may be possible to force it to with something like SwitchResX, but I think macOS in general deems that a way worse experience than just running in 8-bit with full RGB

Yeah mine defaults to 8 bit no matter what. I’ll just return the Mac Studio and buy a pc I think. I will only use this for video editing anyway so don’t really care what os it’s running. Why they put hdmi 2.0 ports in these I’ll never understand as it’s obviously aimed at professionals and I don’t know a single video editor that edits in 8 bit. Not one.

Is there a Thunderbolt to HDMI 2.1 cable?

Sure thing.

As far as I see it, the main display output is intended to be the Thunderbolt/USB-C ports that easily do support full 4k60 10-bit without with full colour sampling. Of course it would be nice for the HDMI port to also be higher spec but much like HDMI on the laptop I more see it as an emergency "need to plug into a projector for a presentation" than main display out since the DisplayPort Alt Mode for the thunderbolt ports is overall superior.

I must admit I also don't much see the point of 10-bit when also having 4:2:0 or 4:2:2 chroma subsampling. Increase the colour encoding space but reduce the number of pixels for which colour information is encoded in the first place. Surely if it is important to have 10-bit it would also be important to have full colour. Though I guess it would make sense if you're working with footage that is itself 4:2:2 or 4:2:0

So this would give me 4k 60 10 bit on a monitor that took usbc as an input? So basically a monitor, not a TV

Monitors are kinda just TVs without TV tuners in them, right?

Can also just use something like this if you only have HDMI on the monitor/TV

Already tried scripts. Made no difference. Bought that Apple adapter and another variant. Both made no difference. Returned both the oled and Mac Studio this afternoon and ordered a pc instead. Why Apple put a hdmi 2.0 port on a £2000 desktop I will never understand. Even there much higher priced MacBook Pros are the same. Form over function and penny pinching by Apple these days. Just ordered a mega powerful pc and will use that.

Are you talking about a TV?

HDR TVs claim to be 10 bit but usually they are 8 bit FRC.

macOS and Windows will detect them as 8 bit displays.

macOS and Windows both have a HDR toggle option that enables HDR but that shouldn’t be used computer usage. Mac and Windows GUIs aren’t supposed to be with ST 2084 gamma profiles.

I’ve done tests with videos and it’s clearly only 8 bit through macOS

Just a little thought for people,Apple designs Mac systems to work with Apple external devices. That includes monitors. It’s make to work with a Pro XDR or a Studio Display. Any thing else is a crap shoot.

8 bit + FRC. It simulates the wide gamut of 10 bit but they aren’t true 10 bit displays.

Most if not all HDR TVs will be picked up at 8 bit + FRC displays by macOS and Windows. This is universally known.

You can enable HDR in both systems but that will mess up the look of the GUI.

That’s just the way it is. They aren’t computer monitors even though they can be used as an OK monitor.
