3. Amzfast 27″ 4K – Also Great
The Amzfast 27″ 4K is a 27-inch 4K UHD gaming monitor built around an IPS panel. It offers a refresh rate of up to 320Hz at a lower resolution.
It works for office tasks too: 4K gives sharp text for documents and spreadsheets.

Best for: gamers who want the sharpest picture.
May not fit if: you need HDMI 2.1 confirmed in the title for 4K at 120Hz on a console.

On paper, the Z-Edge 27″ 1440p 240Hz is a 27-inch 1440p QHD monitor with a 240Hz refresh rate.

6. ASUS ROG Swift OLED PG27UCDM – Worth a Look
On paper, the ASUS ROG Swift OLED PG27UCDM is a 27-inch 4K UHD monitor with a 240Hz refresh rate, using a QD-OLED panel.
OLED is the main reason to look at this one: each pixel lights itself, so blacks are truly black and motion looks clean at high refresh rates. OLED gives per-pixel contrast and very fast response, but static HUD elements can raise burn-in risk over time, so vary your content and use the screen-saver and pixel-refresh features.
Amazon owners rate it 4.5 out of 5 across 233 ratings, so there is plenty of real-world feedback to read before you buy. The title does not state the HDMI version, so check the listing before assuming 4K at high refresh rates on a console.
Best for: players who want deep blacks and very fast response.
May not fit if: you leave static windows on screen for hours or play mostly in a bright room.
7. Samsung Odyssey OLED G8 27″ – Good Alternative
On paper, the Samsung Odyssey OLED G8 27″ is a 27-inch 4K UHD monitor with a 240Hz refresh rate, using a QD-OLED panel. Adaptive sync comes from FreeSync. The listing quotes a 0.03ms response time. Other features mentioned in the listing include HDR HDR support.

How to Choose the 27 Inch 240Hz Monitor
Budget and value
A trusted brand and a solid review history matter more than a long spec list. Check the current listing for the latest offer, because prices change often.
Eye comfort
Look for flicker-free and low blue light features if you spend long hours in front of the screen. They are standard on many modern monitors.
Warranty and support
Check the warranty terms on the listing, and read recent reviews for notes on dead pixels, backlight bleed and support.
Resolution and size
Resolution decides how sharp text and games look at a given size. 1440p is a strong balance for most desks, 4K is sharper but needs a stronger graphics card, and 1080p is the cheapest option.
Refresh rate
A higher refresh rate makes motion and scrolling smoother. 144Hz is a good starting point for gaming, and 240Hz or more helps in fast shooters if your graphics card can keep up.
