After purchasing and connecting my Apple Macbook M1 to my external monitor I've experienced (like many many others) some delays/lags - cursor jittery etc etc.
I've tried:
Alogic USB-C to HDMI 4K
Alogic USB-C to DisplayPort 4K
Apple USB-C to HDMI
Satechi USB-C Slim v2 - connected via an HDMI
None at first, seems to fix the issues until I adjusted the display settings as seen on the video.
Please let me know in the comments if this works out for you as well!
