I've got a couple of Macs that I regularly screen share to using the build-in Screen Sharing app:
A month or two ago, both started looking very pixellated when viewed — text is very difficult to read.
Here's an example:
My first thought was that this was related to Screen Sharing's scaling or quality settings, but I've tried all combinations of both to no avail.
I shrugged it off as a broken update or something, and didn't think anything of it.
Until I screen shared from a different Mac, and both of the remote Macs looked great again:
The problem source Mac specs:
macOS Sierra 10.12.2 (16C67) MacBook Pro (Retina, 15-inch, Early 2013) NVIDIA GeForce GT 650M 1024 MB Intel HD Graphics 4000 1536 MB Screen Sharing v1.7.1 (494.15)
The working source Mac specs:
macOS Sierra 10.12.2 (16C67) Mac mini (Mid 2011) Intel HD Graphics 3000 Screen Sharing v1.7.1 (494.15)
Any idea what's going on here? How do I make screen sharing great again?
