A snippet on Alienware Arena teased Alienware's new AW2521H, a 24.5" 360 Hz monitor with G-SYNC. I'm presuming this monitor uses the same panel as in ASUS's ROG Swift 360 Hz, but Alienware spilled the beans about it being an IPS panel, something that ASUS and NVIDIA didn't reveal back in their January announcement.
As for availability, Alienware used the same phrase as ASUS: "later this year."
So piecing both announcements together, we now have two monitors using a new 360 Hz FHD AU Optronics panel, both with hardware G-SYNC. I originally speculated that ASUS had to be using a TN panel to reach response times that would allow quality 360 Hz operation, but after reviewing the VG279QM, a 280 Hz IPS, I'm at least optimistic that AU Optronics will be able to get close enough.
For the VG279QM, at 280 Hz with the ideal overdrive setting of 80, I measured an average full-scale response (not 10% to 90%) of 6.6 ms. Clearly that doesn't fit in a 280 Hz window of only 3.6 ms, but motion clarity is improved even with partial transitions. If AU Optronics can get this new panel down to an average of around 5 ms, 360 Hz should show marked clarity improvements over 240 or 280 Hz.
I'm very excited to see both of these monitors in action.
