Ready to level up your gaming experience without breaking the bank? The AOC Q27G4ZD QD-OLED monitor is here to prove that premium visuals don't always come with a premium price tag. While OLED gaming monitors are renowned for their stunning color and contrast, many have historically cost a small fortune. But times are changing, and the Q27G4ZD, priced at a competitive $469, is leading the charge. This monitor boasts a crisp 2,560-by-1,440-pixel resolution and a blazing-fast 240Hz refresh rate, putting it in the same league as pricier options like the MSI MPG 271QRX QD-OLED and the Asus ROG Strix OLED XG27AQDMG. It's an Editors' Choice winner for a reason!
Design: An OLED for the Everyday Gamer
Sporting a generous 26.5-inch screen, the Q27G4ZD measures 16 by 23.9 by 9.4 inches (HWD), with an adjustable height up to 21.1 inches. Its design includes a sleek two-pronged stand, similar to the ViewSonic XG275D-4K, but with a more streamlined look. Weighing in at a manageable 14.5 pounds, it's easy to set up and move around. The stand even features a clever hole for cable management and offers a full 90-degree pivot, perfect for those who like a vertical setup.
The monitor's back is predominantly black, lacking the flashy RGB lighting found on more expensive models. The only splash of color is the red circle around the stand's insertion point, keeping the design clean and focused.
Connectivity and Ports
On the connectivity front, you'll find two USB 3.2 ports (plus two extra USB-A ports on the side), a USB-B connector, two HDMI ports, and one DisplayPort. However, it's worth noting that it does not have USB-C ports. The HDMI port is version 2.0, while the DisplayPort is version 1.4.
But here's where it gets controversial... Premium monitors often feature the newer HDMI 2.1 or DisplayPort 2.1, along with USB-C. DisplayPort 2.1 offers more than double the bandwidth of DisplayPort 1.4, allowing for higher resolutions and refresh rates without compression. HDMI 2.1 offers similar advantages. While the Q27G4ZD's lack of these newer ports isn't a deal-breaker, given its 1440p resolution, it does mean you're limited to 144Hz at 1440p over an HDMI 2.0 connection. To unlock the full 240Hz refresh rate, you'll need to use a DisplayPort connection.
The Q27G4ZD uses a QD-OLED (quantum dot organic light-emitting diode) panel with a 2,560 by 1,440p resolution, similar to those found in monitors like the Alienware AW2725DF 360Hz and Asus ROG Strix OLED XG27AQDMG. This resolution on a 26.5-inch screen results in a pixel density of 111 pixels per inch (ppi). While this delivers sharp images, clear text, and excellent detail, it won't quite match the sharpness of 4K monitors like the Alienware 27 4K QD-OLED (AW2725Q) with its 166 ppi.
And this is the part most people miss... You might notice the display's glossiness, which can be reflective when turned off, but it doesn't significantly impact image quality during gameplay.
The Q27G4ZD is equipped with DisplayHDR True Black 400 certification and is Nvidia G-Sync Compatible to reduce screen tearing. It also features a Low Input Lag mode, designed to optimize response times. While we didn't observe a noticeable difference with this mode enabled, it's a welcome feature.
Performance: Colors That Pop and Low Input Lag
Given the Q27G4ZD's competitive price, we don't have many direct comparisons. However, we put it through rigorous testing using Calman calibration software and a Klein K-10A colorimeter. We also tested it with a variety of games to assess input lag and overall performance.
In our brightness tests, the Q27G4ZD achieved a maximum brightness of 240 nits in its default gaming profile over an SDR signal, falling short of its 450-nit rating. Peak HDR brightness reached 247 nits at a 2% window size. This is with the default settings, so there is room for improvement through calibration.
The Q27G4ZD boasts a rated contrast ratio of 1,500,000:1, which is crucial for creating deep blacks and bright whites, enhancing image quality.
Color Gamut Coverage
The Q27G4ZD covers an impressive 99% of the Adobe RGB color gamut, 142.5% of the sRGB gamut, and 99.1% of the DCI-P3 gamut. This excellent color coverage is what you'd expect from an OLED panel.
Gaming Performance
Input lag is crucial in competitive gaming. We used the Leo Bodnar 4K Input Lag Tester to measure the Q27G4ZD's performance across different refresh rates and resolutions.
Here are the results:
- 1080p/60Hz: 14.6ms of input lag
- 1080p/120Hz: 6.3ms
- 1440p/60Hz: 7.5ms
- 1440p/120Hz: 9.1ms
We were unable to test above 120Hz due to the DisplayPort requirement for the 240Hz refresh rate. These results compare favorably with the premium Alienware 27 280Hz (AW2725D), which has 13.8ms of lag at 1080p/60Hz and 7.5ms at 1440/60Hz. Input lag of up to 16ms at 60Hz is generally considered playable. However, for those seeking the absolute fastest response times, esports monitors like the Sony InZone M10S and the LG 27 UltraGear OLED (27GX790A) may be a better fit.
The Q27G4ZD's high refresh rate and low input lag make it an excellent choice for fast-paced games like Doom: The Dark Ages. The OLED panel also makes graphically rich games with vibrant colors or deep blacks look incredible. Games like Clair Obscur: Expedition 33 and Cyberpunk 2077 truly shine on this monitor, showcasing the detail of an OLED panel.
