1. Samsung LS27H70DEANXZA – Best Overall
On paper, the Samsung LS27H70DEANXZA is a 27-inch 4K UHD monitor with a high refresh rate, using an IPS panel. Other features mentioned in the listing include HDR10 HDR support.
It works for office tasks too: 4K gives sharp text for documents and spreadsheets. At 4K, you will want a recent graphics card to hold high frame rates in demanding games, but desktop text and video look very sharp. IPS panels keep colours and brightness consistent from wide angles, which suits shared screens and desk setups.
It holds a 4.2-star average from 102 Amazon ratings, which gives a useful picture of build quality and reliability.
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.
2. GIGABYTE MO27Q28GR OLED – Runner-Up
On paper, the GIGABYTE MO27Q28GR OLED is a 27-inch 1440p QHD monitor with a high refresh rate, using an OLED panel. Adaptive sync comes from FreeSync Premium Pro.
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. We do not quote prices because they change daily, so use the Check Price button to see today’s Amazon price and whether it is currently discounted. 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.
It holds a 4.2-star average from 107 Amazon ratings, which gives a useful picture of build quality and reliability.
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.
3. Dell SE2426HG – Also Great
The Dell SE2426HG is a 23.8-inch 1080p Full HD gaming monitor built around an IPS panel. It offers a 240Hz refresh rate. Adaptive sync comes from FreeSync.
For competitive shooters, a refresh rate of 240Hz gives you a clear motion advantage if your PC can push matching frame rates. A 1080p screen is easy to run on almost any graphics card, which makes high frame rates affordable. IPS panels keep colours and brightness consistent from wide angles, which suits shared screens and desk setups.
It holds a 4.6-star average from 314 Amazon ratings, which gives a useful picture of build quality and reliability.
Best for: competitive players with a powerful graphics card.
May not fit if: you need a specification that is not listed in the title, so check the product page first.
4. GIGABYTE M27Q2 – Solid Choice
The GIGABYTE M27Q2 is a 27-inch 1440p QHD gaming monitor built around an IPS panel. It offers a 210Hz refresh rate. The listing quotes a 1ms response time. Adaptive sync comes from G-Sync Compatible. Other features mentioned in the listing include USB-C connectivity and a built-in KVM switch.
A 1440p resolution is the sweet spot for most gaming PCs, since many mid-range graphics cards can drive it at high frame rates. IPS panels keep colours and brightness consistent from wide angles, which suits shared screens and desk setups.
It holds a 4.5-star average from 90 Amazon ratings, which gives a useful picture of build quality and reliability.
Best for: laptop users who want simple one-cable docking.
May not fit if: you need a specification that is not listed in the title, so check the product page first.
5. Amzfast 27″ 4K – Strong Option
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. At 4K, you will want a recent graphics card to hold high frame rates in demanding games, but desktop text and video look very sharp. IPS panels keep colours and brightness consistent from wide angles, which suits shared screens and desk setups.
It holds a 4.5-star average from 1,615 Amazon ratings, which gives a useful picture of build quality and reliability.
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.
6. Z-Edge 27″ 1440p 240Hz – Worth a Look
On paper, the Z-Edge 27″ 1440p 240Hz is a 27-inch 1440p QHD monitor with a 240Hz refresh rate.
This model is flat, so it is a useful comparison if you decide a curved screen is not for you.
It holds a 4.5-star average from 794 Amazon ratings, which gives a useful picture of build quality and reliability.
Best for: competitive players with a powerful graphics card.
May not fit if: you need a specification that is not listed in the title, so check the product page first.
7. ViewSonic VS3225-2K – Good Alternative
ViewSonic VS3225-2K pairs a 32-inch 1440p QHD screen with a 75Hz refresh rate and a VA panel. The listing quotes a 4ms response time. Other features mentioned in the listing include HDR10 HDR support and built-in speakers.
At 32 inches it fills more of your view, which is great for single-player games and for multitasking, as long as your desk is deep enough. A 1440p resolution is the sweet spot for most gaming PCs, since many mid-range graphics cards can drive it at high frame rates. VA panels offer strong contrast, but dark scenes can show slower pixel transitions than IPS, so check reviews for smearing if you play fast shooters.
Amazon owners rate it 4.4 out of 5 across 455 ratings, so there is plenty of real-world feedback to read before you buy. At 75Hz it is better suited to everyday use than fast action games.
Best for: players who want a balanced 1440p screen.
May not fit if: you play fast shooters and are sensitive to dark-scene smearing.
How to Choose the Second Monitor
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.
Panel type
IPS gives accurate colour and wide viewing angles, VA gives deeper contrast, and OLED gives near-instant response and perfect blacks. Choose by what you do most.
Ports and connectivity
Check for DisplayPort and HDMI, and for USB-C if you want a single-cable laptop setup. Look at the listing for HDMI 2.1 if you use a console.
Adaptive sync
FreeSync or G-Sync compatible support removes tearing when your frame rate changes. Most modern gaming monitors include one of them.
