I ended up buying this monitor because of this review, and I have to say I'm extremely disappointed in the G-Sync capabilities. It has terrible inverse ghosting/overshoot. This is with an EVGA RTX 2070 through displayport @ 240hz.
How does something like this get labeled as G-Sync compatible; the fact that you can physically enable the feature?
The effect is minimized greatly if you're getting over 200fps but in a game like The Division 2 where I hover in the mid 80's, it's unbelievably apparent and actually rather nauseating (not to mention unusable). Even in COD MW I'm getting ~160fps and the issue is still quite apparent, especially on the night missions such as 'Clean House'. Shades of green show it the worst, even at 240fps you can see the overshoot clearly.
Edit: Amazon ended up sending me a replacement unit and it's exactly the same, just going to have to return it as it really isn't G-Sync compatible in the slightest. Running without G-Sync results in an extremely smeary experience. It's a real shame as it does have some of the inkiest blacks I've seen and the colors + contrast are truly impressive.
I even tried using CRU to limit the VRR range to force it to double but it ends up looking extremely smeary and feeling rather slow, regular 240hz mode is better (which isn't saying much).
