For many gamers, especially in the world of competitive gaming, a high refresh rate is often considered more important than resolution or size, as it provides smoother gameplay and possibly an advantage over their lesser-equipped opponents. So far, there aren't many monitors with a 240Hz refresh rate, and most of them have had TN panels, though IPS panels are starting to make their appearance as well. Our list is short for now, but we'll update our recommendations when more of these monitors are released and tested.
We've reviewed more than 100 monitors and below are our recommendations for the best 240Hz monitors to purchase. See also our recommendations for the best gaming monitors, the best 27 inch monitors, and the best ultrawide gaming monitors.
The best 27 inch 240Hz monitor that we've tested so far is the Acer Nitro XV273X. This monitor provides a smooth and immersive gaming experience with its high refresh rate and large screen size. It has a 1080p IPS panel with wide viewing angles and its out-of-the-box color accuracy is one of the best that we've seen.
This monitor has native FreeSync support and it's certified to be compatible with NVIDIA's G-SYNC as well. Its response time is outstanding, and the input lag remains low whether you play at its maximum refresh rate or at 60Hz. There's HDR support, but it can't display a wide color gamut, and although it has a great SDR peak brightness that fights glare easily, it isn't bright enough to truly bring out highlights in HDR content. The IPS panel provides wide viewing angles, which is great for sharing content or for some co-op gaming. There are also four USB 3.0 ports for charging and the monitor has integrated speakers.
Unfortunately, like most IPS panels, its low contrast ratio makes blacks look gray, especially when viewed in a dark environment. Its black uniformity is decent, though, and aside from some minor vignetting at the corners, there's almost no visible dirty screen effect. On the whole, this is a great monitor that even serious gamers should be happy with, making it the best 27 inch 240Hz monitor we've seen so far.
If you want a monitor with better build quality, then check out the Dell Alienware AW2720HF. Although it doesn't have built-in speakers like the Acer Nitro XV273X, it feels extremely well-built and the stand has very little wobble when nudged. The 27 inch, 1080p monitor has a stylish, modern design that fits well in any environment, and there's some RGB lighting on the stand to set the mood. Unfortunately, this monitor also has a poor contrast ratio, and its bad black uniformity can be rather distracting when gaming in the dark. On the upside, it has wide viewing angles and you shouldn't have any issues using this monitor in a bright room thanks to its good peak brightness and great reflection handling.
Overall, the Acer has better performance and has more features like HDR support and built-in speakers, but if build quality is important to you, then the Dell is a better choice.
If you prefer a smaller 25 inch monitor, then the HP OMEN X 25f is the best 25 inch 240Hz monitor that we've tested. Like the Acer Nitro XV273X, it has a 1080p resolution, though it's less noticeable at this size due to the increase in pixel density. It supports FreeSync and will work with recent NVIDIA graphics cards.
Its TN panel has a superb response time and decent color accuracy, but contrast ratio and black uniformity are mediocre, resulting in blacks that look like gray when viewed in the dark. It has a flicker-free backlight to help reduce eye strain during long gaming sessions, and an RGB Ambient Lighting feature which aims to improve the appearance of dark scenes.
Although this monitor has an excellent build quality, its ergonomics are rather disappointing. There are tilt and height adjustments, but it can't be rotated to portrait mode. Overall, this is one of the best 25 inch 240Hz gaming monitors we've seen so far.
The best 1440p 240Hz monitor we've tested so far is the HP OMEN X 27. It's a good overall monitor with great gaming performance, and although it supports FreeSync VRR, it's also G-SYNC compatible with newer NVIDIA graphics cards.
As is the case with most TN panels, the response time is fantastic so motion looks very clear, but there's no black frame insertion feature to reduce any motion blur. The input lag is also incredibly low, responding to your actions quickly. Although its resolution is 1440p, allowing you to see finer details in your games, the picture quality isn't very good with a poor contrast ratio, bad black uniformity, and disappointing viewing angles, so it doesn't perform well in dark rooms and you lose image accuracy when viewed from the side. Luckily, it has good peak brightness and great reflection handling if you want to place it in a bright room.
Unfortunately, even though it supports HDR, its color gamut is limiting and it can't get bright enough in HDR to make highlights pop the way they should. Still, this is the best 1440p 240Hz monitor we've tested so far.
