Okay, so you want a quality gaming monitor for your FPS games. Look no further—you’ve come to the right place. I see you’re trying to skip ahead… please don’t.
With a budget of under $400, you should expect a gaming monitor with a high refresh rate, fast response time and at least a 1440p resolution. I won’t judge if you still prefer a 1080p monitor, though. Many professional esports players (or pros, for short) still choose 1080p displays with extremely high refresh rates and incredibly low response times because they prioritize maximum FPS and the slightest competitive advantage during tournaments and ranked matches.
At this price range, you’ll also find monitors with better image quality, true HDR support, faster response times, and significantly improved motion clarity thanks to lower MPRT (Motion Picture Response Time). The overall gaming experience simply feels smoother and more responsive.
One thing to keep in mind is that these monitors are best paired with mid-range to high-end gaming PCs and gaming laptops. If you own an older GPU like my GTX 1650 Ti, I wouldn’t recommend buying one just yet unless you’re planning to upgrade your graphics card soon. While the monitor will still work perfectly, your GPU won’t be powerful enough to consistently push the high frame rates that monitors like these are designed for. Cards such as the RTX 5070 or Radeon RX 9070 XT are much better suited to take full advantage of a high refresh rate display.
That said, what should you expect from a gaming monitor under $400?
What To Expect From a Gaming Monitor Under $400
At under $400, 1440p is the standard resolution, with most monitors featuring a 27-inch display. A 27-inch monitor offers the best of both worlds, delivering beautiful visuals for immersive single-player games while still being an excellent choice for competitive FPS games.
You should also expect 240Hz or higher refresh rates. When paired with a mid-range or high-end gaming PC or gaming laptop, these monitors can display every frame your GPU produces, resulting in an incredibly smooth and responsive gaming experience.
Most monitors in this price range feature Fast IPS panels, which provide excellent motion clarity with minimal ghosting. When comparing response times, pay close attention to MPRT (Motion Picture Response Time) rather than just GtG (Gray-to-Gray). MPRT measures how quickly moving images appear on the screen, making it far more useful for fast-paced FPS games where reducing motion blur and ghosting is important.
You’ll also benefit from excellent color accuracy, with many monitors covering up to 98% of the DCI-P3 color gamut. This isn’t just great for gaming—it also makes these monitors an excellent choice for content creators who edit videos, work with 3D models or use software like Adobe Photoshop.
Modern connectivity is another advantage. Most gaming monitors under $400 include HDMI 2.1 and DisplayPort connections, providing the bandwidth needed for high resolutions and refresh rates.
To eliminate screen tearing and stuttering, these monitors also support Adaptive Sync technologies such as AMD FreeSync Premium and NVIDIA G-SYNC Compatible, ensuring a smoother gaming experience even when your frame rate fluctuates.
Finally, you’ll typically find fully ergonomic stands with height, tilt, swivel and pivot adjustments, making it much easier to position the monitor comfortably whether you’re gaming, working or creating content.

Common Mistakes When Buying a Gaming Monitor Under $400
1. Buying an OLED Monitor Expecting Miracles
Many gamers assume an OLED monitor is perfect because of its infinite contrast, true blacks and lightning-fast response times.
Why it’s a mistake: While OLED monitors deliver an incredible gaming experience, they aren’t without drawbacks. Static elements such as game HUDs, taskbars or desktop icons can eventually cause burn-in, although modern OLED monitors include features that greatly reduce this risk.
Advice: If you mainly play immersive single-player games or watch movies, OLED is an excellent choice. However, if you spend thousands of hours playing competitive games with static HUDs, a Fast IPS or Mini-LED monitor may be the better long-term option.
2. Buying a 4K Monitor Under $400
Many buyers are tempted by the words “4K Resolution.”
Why it’s a mistake: At this budget, many 4K monitors sacrifice refresh rate, HDR quality or overall panel performance. You’ll often end up with a slower monitor that isn’t ideal for competitive gaming.
Advice: For around $400, a 1440p 240Hz gaming monitor offers a much better balance of image quality, refresh rate and overall gaming performance. Save 4K for a higher budget if you want the complete experience.
3. Ignoring Monitor Calibration
A lot of people plug in their new monitor and never touch the settings.
Why it’s a mistake: Factory settings aren’t always accurate. Colors may appear washed out, brightness may be too high, and the monitor may not deliver its full image quality straight out of the box.
Advice: Spend a few minutes adjusting the brightness, contrast and color profile. You can also use calibration software or your monitor’s built-in picture presets to achieve a more accurate image.
4. Using the Wrong Cable
Many gamers unknowingly connect their high-refresh-rate monitor using an older HDMI cable.
Why it’s a mistake: Older standards like HDMI 1.4 may not support the monitor’s maximum refresh rate or features such as Variable Refresh Rate (VRR), AMD FreeSync or NVIDIA G-SYNC Compatible.
Advice: Whenever possible, use a DisplayPort cable or HDMI 2.1 if your monitor and graphics card support it. This ensures you get the highest refresh rate and all the gaming features your monitor offers.
5. Forgetting to Enable the Maximum Refresh Rate
This is one of the most common mistakes new PC gamers make.
Why it’s a mistake: Even after buying a 165Hz, 240Hz or higher refresh rate monitor, Windows often defaults to 60Hz, meaning you’re not getting the smooth gameplay you paid for.
Advice: Open Windows Display Settings, go to Advanced Display Settings, and select your monitor’s highest available refresh rate. Then enable AMD FreeSync or NVIDIA G-SYNC Compatible for the smoothest possible gaming experience.
