Sierra screen sharing poor resolution

Hi,

Since Sierra, using screen sharing to access my iMac (also on Sierra) has been hard on my sight!

Indeed the remote screen keeps refreshing all the time and is pixelized a lot and display a bunch of small "ghosts" everywhere, compared to an almost perfect screen sharing display before Sierra.

The only thing that has changed are the OS on both my iMac 2009 and MacBook Pro 2014.

Of course I've setup the Quality to : "Show the screen at full quality" but that doesn't change anything

I've played with my iMac res, but no change.

Any idea?

MacBook Pro (Retina, 13-inch, Mid 2014), iOS 10

Hello johnnygoodface,

Thanks for that info and choosing the Apple Support Communities. Based on what you stated, it seems you are experiencing issues with screen sharing. Based on what you described, I would adjust settings in Preferences like View > Turn Scaling Off or View > Turn Scaling On and “Adapt quality to network conditions” under Quality.

You can figure out if unexpected behavior is related to a user file or setting by trying to reproduce the issue from another user account. This process includes creating a new user account, logging in to it, and testing for the issue.

Thank you

But I've already tried your recommendations

The best solution for me was to lower my iMac's resolution.

Since I'm less and less in front of my physical iMac, this makes it much easier to remote control my iMac from my MBP

Cheers.
