Auros CV27F has 1ms response time as displayed on amazon ( https://www.amazon.in/dp/B07Z2S4MMM/ref=cm_sw_r_cp_apa_i_7-0fEbH0GQ0BT )but according to this video
it's 8.4ms (at 8:30 min into the video). Should i buy this monitor? Also are there any other good monitors under 450usd (requirments: 144hz, 1ms response time, AMD free sync, 27in 1080p display)
