Fastest Refresh1 of 5
AOC C27G4ZH Curved on Amazon (opens in a new tab)
AOC's C27G4ZH curves a 27-inch 1080p VA panel and runs it at 280Hz on a height, tilt and swivel stand.
Best for
- Esports players with a GPU that can feed high frame rates.
Skip if
- Pass on it if a VA panel that can smear dark transition rules it out for your setup.
Why we like it
It trades resolution for speed. On refresh rate it leads this guide at 280Hz, ahead of the 25G51Z (260Hz). It matches the Q27G41ZE and the Q27GAZDV on screen size (27 inches).
It shares a 1920x1080 (1080p) resolution with the 25G51Z; the Q27GAZDV goes with a 2560x1440 (1440p) resolution. A VA panel is unique to it among these picks, while the Q27G41ZE uses an IPS panel. It also comes with 280Hz on a 1500R curve and VESA mounting.
At 1080p, 280Hz is within reach of mid-range graphics cards in esports titles; use DisplayPort if your card's HDMI port is older. When we checked, only the Q27G41ZE and cheaper picks cost less, and the Q27GAZDV cost more.

Skip if
- Skip it if screen size matters most to you; the C27G4ZH offers 27 inches.
Why we like it
On refresh rate it sits mid-pack at 260Hz: the C27G4ZH offers 280Hz, and the AG276QZD2 comes in at 240Hz. Its 25 inches screen size is the smallest in this group; the C27G4ZH leads at 27 inches. It shares a 1920x1080 (1080p) resolution with the C27G4ZH; the Q27G41ZE goes with a 2560x1440 (1440p) resolution.
It shares an IPS panel with the Q27G41ZE; the Q27GAZDV goes with a QD-OLED panel. At 1080p, 260Hz is within reach of mid-range graphics cards in esports titles; use DisplayPort if your card's HDMI port is older. G-SYNC Compatible works on NVIDIA cards over DisplayPort, and FreeSync covers AMD cards. No other pick here cost less at our last price check, and the Q27G41ZE was closest.

Skip if
- Skip it if price comes first: the 25G51Z cost less when we checked.
Why we like it
It is rare to see that combination at this price. It matches the Q27GAZDV and the AG276QZD2 on refresh rate (240Hz). On screen size it ties with the C27G4ZH and the Q27GAZDV at 27 inches.
Like the Q27GAZDV and AG276QZD2, it has a 2560x1440 (1440p) resolution, while the C27G4ZH uses a 1920x1080 (1080p) resolution. Like the 25G51Z, it has an IPS panel, while the AG276QZD2 uses a QD-OLED panel. It also offers DisplayPort 1.4 and HDMI 2.0 inputs.

On price it sat second of 5, between the cheaper 25G51Z and the pricier C27G4ZH, at the time of writing.

How We Chose These AOC Gaming Monitors
Each pick was assessed across 4 criteria weighted for real-world use.
- Resolution and refresh
- We compared listed resolution and refresh rate against the graphics power each needs.
- Connectivity and stand
- We checked ports, USB-C and stand adjustment where the listing states them.
- Panel
- We noted panel type and the trade-offs it brings for motion, contrast and burn-in.
- HDR and colour
- We recorded DisplayHDR certifications and listed colour gamut.
What to Look for in an AOC Gaming Monitor
Key buying criteria so you get the right fit the first time.
Decide on refresh rate first
Among these picks, refresh rate runs from 240Hz on the AG276QZD2 to 280Hz on the C27G4ZH. Settle how much you need before comparing prices, since paying for more rarely helps if your use never reaches it.
Choose a refresh rate you can reach
A higher refresh rate only helps when your PC delivers matching frame rates. 144Hz to 180Hz suits most players; 240Hz and above rewards competitive shooters.
Check ports and cables
High refresh rates at 1440p and 4K need DisplayPort 1.4 or HDMI 2.1. Consoles need HDMI 2.1 for 4K at 120Hz.
Consider the stand
A stand with height, tilt and swivel adjustment saves buying a monitor arm. Check VESA mounting if you plan to use one anyway.
Pick the panel type
IPS offers wide viewing angles and good colour. VA has higher contrast but slower dark transitions. OLED has perfect blacks and very fast response but carries a burn-in risk with static content.

Frequently Asked Questions
Which of these monitors has the largest screen size?
The C27G4ZH, at 27 inches. The Q27G41ZE follows at 27 inches, while the 25G51Z has 25 inches.
What is the least I can spend on one of these monitors?
Start with the 25G51Z, the lowest-priced pick when we checked. The AG276QZD2 is the premium end, so the spread between them shows what extra money buys here.
Is 1080p fine on a 27-inch monitor?
It works, but text and detail look softer. 1440p is sharper at 27 inches; 1080p is best at 24 to 25 inches.
Does a 1ms response time rating matter?
Makers measure response time differently, so compare panel type and independent reviews rather than the headline figure.
Does a FreeSync monitor work with an NVIDIA card?
Most do as G-SYNC Compatible over DisplayPort. Check the product page or NVIDIA's compatibility list for the model.
Bottom Line
Our first pick is the C27G4ZH. Look at the 25G51Z for a lower price than the Q27G41ZE and the rest when we checked, the Q27G41ZE for an overclocked 260Hz mode above its 240Hz native rate and the Q27GAZDV for HDMI 2.1 and DisplayPort 1.4 inputs for PC, PS5 and Xbox Series X if those matter more to you.
