Frequently Asked Questions

How does Dual Frame work?
A dedicated button toggles between native 4K (3840x2160) at 160Hz and pixel-binned FHD (1920x1080) at 320Hz - one screen handles both AAA and esports.
Will PS5 / Xbox Series X run at 4K 120Hz?
Yes - HDMI 2.1 with VRR and ALLM supports 4K 120Hz from PS5 / Xbox Series X for supported games.
How does it compare to the Gigabyte M27UP?
U27G4R uses Fast IPS (sharper motion) vs Gigabyte's SS IPS, both at 4K 160 / FHD 320 Dual Mode. Gigabyte has KVM + USB-C, AOC has dual HDMI 2.1 + 4-port USB hub.
Does it have USB-C?
No - the U27G4R uses HDMI 2.1, DisplayPort 1.4 and USB-A only. For USB-C laptop docking choose the AOC CU34P3CV or Q27P3CW.
Singular Expert Insight
Choose the U27G4R if you want dual-mode 4K 160Hz / FHD 320Hz gaming with Fast IPS motion at AOC pricing. If you need USB-C laptop docking step to the Gigabyte M27UP (KVM + USB-C); for OLED contrast choose a QD-OLED gaming model.
