How We Chose These 1440p 240Hz Monitors
Each pick was assessed across 4 criteria weighted for real-world use.
- Panel
- We noted panel type and the trade-offs it brings for motion, contrast and burn-in.
- Resolution and refresh
- We compared listed resolution and refresh rate against the graphics power each needs.
- Connectivity and stand
- We checked ports, USB-C and stand adjustment where the listing states them.
- HDR and colour
- We recorded DisplayHDR certifications and listed colour gamut.
What to Look for in a 1440p 240Hz Monitor
Key buying criteria so you get the right fit the first time.
Pick the panel type
IPS offers wide viewing angles and good colour. VA has higher contrast but slower dark transitions. OLED has perfect blacks and very fast response but carries a burn-in risk with static content.
Choose a refresh rate you can reach
A higher refresh rate only helps when your PC delivers matching frame rates. 144Hz to 180Hz suits most players; 240Hz and above rewards competitive shooters.
Match resolution to your graphics card
1080p suits entry and mid-range cards and high refresh rates. 1440p is the balance for most gaming PCs. 4K needs a high-end card to hold high frame rates.
Pick the resolution your card can drive before looking at refresh rate.
Size for your desk distance
24 to 25 inches suits 1080p and competitive play at a typical desk. 27 inches pairs well with 1440p and 4K; 32 inches suits 4K at a deeper desk.
Read HDR labels carefully
HDR10 means the monitor accepts an HDR signal, not that it displays it well. DisplayHDR 600 or True Black 400 certifications say more about real HDR performance.
Check ports and cables
High refresh rates at 1440p and 4K need DisplayPort 1.4 or HDMI 2.1. Consoles need HDMI 2.1 for 4K at 120Hz.

Frequently Asked Questions
Does a 1ms response time rating matter?
Makers measure response time differently, so compare panel type and independent reviews rather than the headline figure.
Should I use HDMI or DisplayPort?
On a PC, DisplayPort usually supports the highest refresh rates. HDMI 2.1 is equivalent and needed for consoles.
Is HDR worth it on a budget monitor?
Rarely. Budget HDR10 monitors accept HDR but lack the brightness and contrast to show it well. OLED or DisplayHDR 600 models do it better.
Do I need a GPU that matches the refresh rate?
To benefit fully, yes. A 240Hz monitor still feels smoother at 150fps than a 144Hz one, but the gains shrink when frame rates are far below the refresh rate.
Is 1080p fine on a 27-inch monitor?
It works, but text and detail look softer. 1440p is sharper at 27 inches; 1080p is best at 24 to 25 inches.
Is OLED burn-in still a problem?
It is a risk with static elements over many hours. Current OLED monitors use pixel-refresh routines to reduce it; check the maker's warranty for burn-in coverage.
Bottom Line
The MSI MAG 271QPX QD-OLED E2 is the pick, the LG 27GX704A-B is a strong alternative, and the GIGABYTE GO27Q24G is the cheapest OLED.
The Alienware AW2723DF suits IPS buyers, the AOC AGON PRO AG276QZD2 is another QD-OLED option, and the KTC H27E6S is the budget choice.
