Hi to all,
I have a Lenovo L14 as workstation that I want to connect to my personal Apple Studio Display.
To do this, I buyed a CAC-1333.
I connected the HDMI side to Lenovo and the USB TYPE C side through the thunderbolt cable of the Apple Studio Display.
The result is that the ASD flicker a lot and it s not usable at all.
What is wrong? Could you guys help me?
A CAC-1332 might be preferable because it includes a USB 2.0 connection to support the USB devices of the display (audio, camera, brightness control, USB ports, etc.). I don’t think club-3d makes the CAC-1332 anymore. In that case, there’s the CAC-1336 which can do 5K, unlike the earlier adapters, but that depends on the GPU.
I don’t know if the CAC-1332 or CAC-1336 will work better with the Apple Studio Display than your CAC-1333.
One thing I would try is replacing the Thunderbolt cable with a normal USB cable (10 Gbps).
Another thing I would try is putting a Thunderbolt 4 hub between the adapter and the display. It helps with the CAC-1336 for non-USB-C displays.
Exactly which Lenovo L14 do you have?
The Lenovo L14 only has HDMI 1.4? That might be good enough for 1440p60.
Doesn’t the Lenovo L14 have a USB-C port that supports USB-C DisplayPort Alt Mode? I would try that.
Hi joevt, firt of all thanks for your reply.
I already tried to replace the thunderbolt cable with a belkin cable and the apple ipad usb-c cable but both of them do not work at all. I mean the ASD do not power on at all.
I can try with the Lenovo HUB but honestly i do no undesterstand how it can help.
The Lenovo L14 in my knowledge has this ports:
HDMI 1.4b
x1 USB-C first gen
x1 USB-C second gen
this is the link of the tech specification of the lenovo: https://psref.lenovo.com/syspool/Sys/PDF/ThinkPad/ThinkPad_L14_Gen_1_AMD/ThinkPad_L14_Gen_1_AMD_Spec.pdf
Then what u suggest to do?
I just tried with the Lenovo Usb-c mini dock (lenovo 40au0065it) but the result is the same 🙁 flickering all time
The spec says both USB-C ports support DisplayPort 1.2 so that’s what I would use to connect the display.
The USB-C cable needs to be able to support 10 Gbps data transfer.
Some USB-C cables are only for charging which means they are USB 2.0 only (480 Mb/s). I suppose if you used such a cable then you wouldn’t see any image at all – no flickering – just black – like no connection.
Have you verified with another computer that the Apple Studio Display works without flickering?
Update graphics drivers?
yes obviously with my Mac Studio it works perfectly but… what is the difference between a cable 3.1 and the thunderbolt 4. I mean I do not want to buy another useless cable… are u sure that could be some differences?
No, I am not sure.
A Thunderbolt 4 cable should work. But since it doesn’t, then what is there for you to do?
Basically, when trouble shooting a problem, it helps to find what works by replacing parts – drivers, computer, gpu, cable, display, etc.
Have you verified with another display that the L14 can output a signal from its USB-C ports?
The Studio Display is not Thunderbolt 4 so it might not have a Thunderbolt 4 cable. It might be a Thunderbolt 3 cable.
Hi joevt and herringbur,
I just tried with a Belkin Thunderbolt 3 cable retro compatible with usb-c 3.1 at 10gbps.
the result is that only the audio of ASD works… no image at all….
:'( idk how to do
Is the display detected at least? Maybe you need to check the display mode. Choose a 4K or 1440p mode, RGB. Check the EDID with Custom Resolution Utility.
Maybe search elsewhere for help. Google the following:
“apple studio display” “windows”
