AOC just launched the U27G4F gaming monitor in China, bringing dual-mode functionality to very interesting price point. At 1,799 yuan (approximately $252), this 27-inch display lets you toggle between ultra-sharp 4K visuals at 190Hz and lightning-fast Full HD at 380Hz. While high refresh rate monitors have been getting more accessible, finding dual-mode capability at this price breaks new ground in the budget gaming segment.
The standout feature here is of course the dual refresh rate system, which sidesteps the old conflict betweeb pixel-perfect clarity or buttery-smooth fame rates. If you own the current AOC U27G4, there is no need to consider upgrading, because most aspects of the U27G4F are identical.

Both monitors share the same 27-inch Fast IPS panel technology, DisplayHDR 400 certification, and 450 nits brightness. The fundamental color accuracy also remains consistent between generations. What’s changed is AOC’s ability to push the refresh rates higher, likely through improved panel binning and more aggressive firmware optimization.
That earlier model maxed out at 4K 160Hz and FHD 320Hz, whereas the new U27G4F bumps those figures to 4K 190Hz and FHD 380Hz. The 30Hz increase at 4K is modest, but the 60Hz jump in FHD mode might be more significant for competitive esports gamers in Counter-Strike 2 or Valorant.
Even regardless of the refresh rate upgrades, the U24G4’s 10-bit Fast IPS panel delivers 99% sRGB and 95% DCI-P3 color gamut coverage, which puts it in respectable territory for both gaming and content creation. Each unit ships with factory calibration achieving Delta E less than 2, plus an individual calibration report verifying that precision.
Fast IPS technology deserves special mention here. Unlike traditional IPS panels that once struggled with response times, Fast IPS delivers that signature IPS color accuracy while matching the speed of older TN panels. It’s why AOC can credibly claim 1ms response times without resorting to aggressive overdrive settings that introduce ghosting.
Features Galore for Competitive Gaming
Beyond the core specs, AOC loaded the U27G4F with gaming-focused extras. The AI dynamic crosshair provides customizable reticle overlays, while sniper zoom assist magnifies distant targets. There’s also an FPS counter, real-time visual engine that adjusts brightness and contrast on the fly, and MBR Sync technology for enhanced motion clarity.
Additional gaming tools include Shadow Control for revealing details in dark scenes, Game Color tuning for adjusting saturation, and Game Tone Adjustment. Picture-by-Picture and Picture-in-Picture modes let you view multiple sources simultaneously, handy when you’re monitoring stream chat or watching build guides while playing.
For eye comfort during marathon gaming sessions, AOC included hardware-level low blue light filtering and DC dimming without flicker. The stand offers comprehensive adjustments: tilt from -5° to 23°, swivel up to ±30°, pivot rotation up to ±90°, and 130mm of height adjustment. It’s also compatible with standard 100×100mm VESA mounting if you prefer a monitor arm.
The Real Stand-Out Feature: Price
At $252, the U27G4F undercuts virtually everything in the dual-mode space. You could actually buy two of these monitors for less than a single Alienware AW2725QF. That value proposition becomes even more striking when you consider the U27G4F actually offers higher refresh rates in both modes compared to many pricier alternatives.
What curbs our enthusiasm somewhat is the China launch factor. Launch pricing in the Chinese market often runs lower than eventual international releases, so expect some upward adjustment if and when the U27G4F reaches other regions like North America and Europe. Still, even with a 20-30% price increase for global markets, this monitor would remain competitively priced.
