CAC 1333 with Apple Studio Display and MacBook Pro Early 2013

I am trying to get my MacBookPro (13′, Early 2013) to work with my Apple Studio Display

Connecting the HDMI output to the CAC 1333 the ASD does show a picture, however resolution is low and the picture is blurry. Using the default Display menu, the highest resolution shown is 1600×900

SwitchResX gives the option of 2560 x 1440, however the picture is still very blurry

Can anyone help please? Thank you!

Maximum resolution over HDMI is 1080p60Hz for the MacBookPro early 2013 . Going 2560×1440 will make it go to 30Hz. I assume this is why it’s “blurry”.

You might want to try the CAC-1173

CAC-1173 is for HDMI output.

The Apple Studio Display only takes Thunderbolt or USB-C DisplayPort Alt Mode input.

The MacBook Pro (Retina, 13-inch, Early 2013) may be limited to 2560×1440 60Hz. Maybe it can do 4K30 from the Thunderbolt port or HDMI port?

A CAC-1332 may allow the USB functions of the display to work (brightness control, camera, audio) but for some reason Club-3d replaced it with the less functional CAC-1333.

The CAC-1336 also allows USB and it can allow up to 5K or 6K width (but your MBP would still be limited to 1440p60 or 4K30).

I think the best connection would be to use an Apple Thunderbolt 3 to Thunderbolt 2 Adapter with a Thunderbolt 2 cable. This way you get up to 10 Gbps USB from the USB-C ports of the Apple Studio Display instead of just USB 2.0 (480 Mb/s).

For full 5K60, you would need an eGPU. Check for examples/solutions.

Thank you. I tried the Thunderbolt 3 to Thunderbolt 2 adapter + Thunderbolt 2 cable, unfortunately it doesn’t work. The MacBook does recognise that something is plugged in (most of the windows disappear from the inbuilt screen) however nothing is visible on the display
