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 90 monitors and below are our recommendations for the best 240Hz monitors to purchase in 2020. See also our recommendations for the best gaming monitors, the best 27 inch monitors, and the best ultrawide gaming monitors.
The best 240Hz monitor in a 27 inch size that we've tested so far is the Acer Nitro XV273X. It's an IPS monitor with good build quality and ergonomics, and its exceptional out-of-the-box color accuracy is one of the best that we've seen. Viewing angles are great, response time and input lag are outstanding, and there's even an optional black frame insertion feature that helps clear up the image of motion blur. There's support for FreeSync variable refresh rate, and it's certified to be compatible with recent 10- or 20- series NVIDIA graphics cards too.
Like most IPS panels, this monitor has great viewing angles, and it has impressive peak brightness to overcome glare in bright rooms. However, its peak brightness in HDR mode isn't enough to bring out small specular highlights in HDR content. There are built-in speakers if you don't already have dedicated ones, and there's a USB hub that includes four USB 3.0 ports to charge your devices or to plug in other peripherals. If you're concerned about eye strain, the backlight is flicker-fee and there's a blue light filter as well.
On the whole, although its resolution is a meager 1080p, this monitor should satisfy those looking for a large monitor with a 240Hz refresh rate.
If you're looking for something a bit cheaper and you don't need HDR, check out the Dell Alienware AW2720HF. Like the Acer Nitro XV273X, this is also a 1080p monitor with an IPS panel, with great viewing angles and reflection handling. Contrast ratio isn't as good and black uniformity is terrible, but its build quality is excellent and its impressive ergonomics allow for all manner of adjustments. As mentioned, this monitor doesn't support HDR and it doesn't have black frame insertion, which the Acer has. Response time and input lag are outstanding, and there's even RGB lighting on the back of the monitor to give it some flair.
Overall, the Acer performs better and has more features, but if you don't care for HDR, you can save some money by going with the Dell.
If you prefer a smaller 25 inch monitor, then go with the HP OMEN X 25f, 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 variable refresh rate, and will work with recent 10- or 20- series 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.
Although this monitor has an excellent build quality, its ergonomics are rather disappointing. There's tilt and height adjustments, but it can't be rotated to portrait mode. 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. Overall, this is one of the best 240Hz gaming monitors in a smaller, compact size.
The best 1440p 240Hz monitor that we've tested so far is the HP OMEN X 27. It's a larger, 27 inch variant of the HP OMEN X 25f. The increase in resolution and size make it perfect for nearly every type of games. It's also suitable for productivity, with plenty of screen real estate to have multiple windows opened at the same time. Unfortunately, like its little brother, it has a sub-par contrast ratio and bad black uniformity, though this is expected of most TN panels. Viewing angles are disappointing; however, it does have great SDR peak brightness and impressive reflection handling for a well-lit room.
Response time is simply outstanding and there's almost no blur trail behind fast-moving objects. There's support for HDR as well, but the monitor's peak brightness in HDR mode isn't high enough to really bring out small highlights. The backlight is technically not flicker-free, but its frequency is so high that most people won't notice it and it doesn't cause any artifacts. Like all monitors with a high refresh rate, it supports FreeSync for a nearly tear-free gaming experience.
If you want a 240Hz monitor without compromising on resolution, this is the one for you.
