I have this annoying sync problem on multi display clone setup where the PC can only sync with 1 display and the other display is tearing. It might be a Win8 problem or AMD problem (Kaveri). I think I don't have this problem on XP using AMD IGP (Athlon X3). Because of my problem, it got me thinking...
What's going to happen with this A-sync or G-sync in multi display environment? The scenarios are:
1. 2 or more display all sync capable (exactly same spec).
2. Same as above, only different spec (one maybe tops at 60Hz, other at 120Hz).
2. Only 1 display is capable of sync.
I assume for no. 1 shouldn't be a problem but you never know.
For no. 2, if I remember correctly, for A-sync they propose several range of sync. Can the higher refresh rate display adapt to the lower range of the lower refresh rate display? This is probably a display manufacturer problem, but again, you never know for sure.
For 3, maybe you can't use sync at all and just use it as regular v-synced display. Or it will sync at the expense of tearing on regular display?
Edit: sync capable is A/G-sync display. Regularly display is non A/G-sync display.
