Hi
Why the resolution 5120x1440 Doesn't work with the New Apple M1 ...
You indicate on the website '' One display with up to 6K resolution at 60Hz connected via Thunderbolt and one display with up to 4K resolution at 60Hz connected via HDMI 2.0 ''
But I can only use the resolution 3840 x 1080 not my native resolution 5120 x 1440.
Can I have a explication please ?
Thanks in advance
Mac mini 2018 or later
May I know which cable do you use and which version of macOS? Tried on 11.2 RC3 and it breaks the previously working setup.
May I know which kind of cable do you use? Thanks.
macOS 11.1? Which type of Caldigit dock is that?
Caldigit TS3+
Thanks however by right it should works with just USB C/TB3 to DP directly - it was worked for me until I tried the 11.2 RC3. Somehow something in that update brake this configuration :(
Latest Big Sur update gives me 5120x1440 120hz and freesync but only with Display Port 1.2. If I change to Display Port 1.4 I any get a blank screen. Any idea why? Samsung CR49
Are you on Big Sur 11.1? What brand & type of cable do you use?
Yes 11.1
Just noticed that my cable may not be a true 1.4.
New one being delivered today. I’ll let you know.
Correction to my post above. I’m running 11.2
My display now works with 11.2 (so far) at 5120 x 1440 @120hz SDR on DP1.4 wFreeSync on.
New mid-Rez modes also seem to exist (HDPI?). More to test.
Which make of cable are you using?
yah good to know what is the brand/type.
Weird, I have the same cable but doesn't work for me.
Did you ever figure this out or get a cable that allowed you to get 120hz?
I got it working. Macbook M1 pro with Samsung CR49 monitor, 120hz, DisplayPort 1.4 and Freesync to Ultimate Engine. I got a CallDigital TS3 Plus.
