Compared to Full HD, this panel displays roughly 1.8 times more detail, which makes it easier to spot enemies and track fast-moving action in competitive shooters. The high refresh rate also contributes to smoother motion, reducing the visual strain of rapid camera movements. At the heart of this display is an AHVA panel with 178° viewing angles in both directions. Colors and contrast remain stable even when you view the screen from an angle, which is a practical benefit for shared viewing or multi-monitor setups. The monitor also supports AdaptiveSync, a variable refresh rate technology that helps eliminate screen tearing and stuttering during gameplay. Response time can be pushed down to 1ms (GTG) by setting the Dynamic OD function to level 3. Internal frame latency is rated at approximately 0.05 frames (about 0.16ms), which keeps input lag low in fast-paced titles. Positioned as an entry-to-mid-tier gaming display, the EX-GDQ271UA offers a well-rounded feature set for gamers who want high refresh rates without stepping up to a premium price bracket. ## Compatibility Guide The monitor provides HDMI and DisplayPort inputs. To take full advantage of the 275Hz refresh rate, a DisplayPort connection is generally the better choice, as it offers the bandwidth needed for high refresh rates at WQHD resolution. Check your graphics card's output specifications to confirm which ports support the full refresh rate. VESA mounting is supported, so you can attach the monitor to a third-party arm or wall mount. The included stand offers tilt adjustment, letting you set the screen angle to your preference. This flexibility is useful for users with limited desk space or those who want to build a multi-monitor arrangement. To drive WQHD at high refresh rates, a capable graphics card is essential. While the monitor itself handles the display side, your GPU must be powerful enough to render frames at the target resolution and refresh rate. A mid-range or higher graphics card is recommended for a satisfying experience. ## Product Info The EX-GDQ271UA was released on October 27, 2025. It features a 27-inch AHVA panel with WQHD resolution, a 275Hz maximum refresh rate, and 1ms (GTG) response time. HDR support is also included, allowing compatible content to be displayed with a wider dynamic range. In the current monitor market, this model sits in the entry-to-mid tier. It delivers a combination of WQHD resolution and a high refresh rate that appeals to gamers seeking a balance between visual detail and smooth motion, without the premium cost of flagship models. ## Best Use Cases - Competitive FPS and TPS players who need smooth motion and low latency. The 275Hz refresh rate and minimal internal delay help track enemies more accurately. Not ideal for those who prioritize 4K visual fidelity above all else. - Creators who want more screen real estate than Full HD offers. The WQHD resolution provides a larger workspace for editing and design tasks. However, professionals requiring factory-calibrated color accuracy should look at higher-end models. - Users who want a single monitor for both gaming and everyday use. The high refresh rate and wide viewing angles cover everything from games to video streaming. Not suitable for those who need a portable display for travel. ## Things to Consider To get the full 275Hz experience, you need a graphics card and cable that support the required bandwidth. DisplayPort is typically the recommended connection for high refresh rates, so verify your setup before purchasing. The 1ms (GTG) response time is achieved with the Dynamic OD function set to level 3. Depending on the setting, response time may vary, and aggressive overdrive can introduce overshoot or ghosting artifacts. It is worth testing different levels to find the sweet spot for your eyes. WQHD resolution places a heavier load on the GPU compared to Full HD. If your graphics card is older or entry-level, you may not reach high frame rates in demanding titles. Consider whether your current PC can handle the resolution and refresh rate you expect. ## FAQ Q: Can I use this monitor with a PS5 or Xbox Series X? A: Yes, the HDMI port allows connection to game consoles. However, the maximum resolution and refresh rate may be limited by the console's output specifications.
