- mattgreenrocks 6y agoI’m guessing this is why the cursor seems to visibly ghost when hooked up to my MBP.
- iamacyborg 6y agoI've not seen that, the bug I'm referring to is to do with putting the mac to sleep when it's connected to the screen.
- mattgreenrocks 6y agoOh, I think I’ve had that: it’s a total crapshoot as to whether it wakes? I thought it was a USB power problem for the longest time.
- arafsheikh 6y agoSounds like for some reason the monitor is running at 30Hz. You can confirm that using an app like EasyRes.
- bartvk 6y agoSystem Preferences can also show this, check my other comment in this thread.
- bartvk 6y agoYou can check the refresh rate as follows. Open System Preferences, then click on Displays. There's a radio button, titled "Scaled". Option-click that radio button, and you'll see a pull-down menu, titled "Refresh Rate". It should be 60 Hz or higher.
