Still loving mine and now i've upgraded from a 1st gen i7 to a 12th gen i7 I can finally make good use of that high referesh rate.
However, i've been experiencing the black screen for a second or two issue in some games that others have commented on here and elsewhere.
Seems to boil down to a gsync issue possibly at native res.
My old pc had a 970 which is does gsync but not gsync compatible. The 2721dgf is gsync compatible, so I guess I was blissfully unaware of this issue. New pc has a 1080 which is gsync compatible.
Turning gsync off fixes any issues with black screen during games, but of course thats not a proper fix.
I have learnt that a firmware upgrade for dp ports may sort this out, link below:

Will try when I have the chance.
