Samsung G80SH 27″ 4K OLED 240Hz Gaming Monitor

The Samsung G80SH combines two features that gamers previously had to choose between: high 4K resolution and a refresh rate suitable for fast competitive play.

At 240Hz, the monitor can refresh its image every 4.17 milliseconds, compared with 8.33 milliseconds at 120Hz and 16.67 milliseconds at 60Hz.

This creates opportunities for smoother motion and more frequent visual updates, particularly in fast-paced games.

The 0.03ms response time also helps minimise visible pixel-transition blur, although overall motion clarity depends on refresh rate, game performance and display settings.

For games such as Counter-Strike 2, Valorant, Apex Legends and Call of Duty, the G80SH is particularly attractive to players with powerful gaming PCs capable of producing high frame rates.

At the same time, its 4K resolution provides detailed visuals for story-driven games, simulations and open-world titles.

The Samsung G80SH provides connectivity for gaming PCs, consoles and compatible laptops.

Its two HDMI 2.1 inputs and DisplayPort connection offer options for high-resolution gaming devices.

USB-C connectivity supports up to 98W Power Delivery, making the monitor useful for setups that combine a gaming desktop with a compatible work laptop.

The integrated USB 3.2 Gen 1 hub provides two USB-A downstream ports for compatible peripherals.

This makes the G80SH relevant for users who want one monitor for both high-end gaming and everyday productivity.

Is a 240Hz OLED monitor worth choosing over a conventional 4K 144Hz display?

The answer depends on your graphics hardware and the games you play.

Feature	Samsung G80SH	Typical 4K 144Hz LCD
Resolution	3840 × 2160	3840 × 2160
Refresh Rate	240Hz	144Hz
Frame Interval	4.17ms	6.94ms
Panel Technology	OLED	IPS or VA
Pixel Response	0.03ms advertised	Varies by model
Black Levels	Pixel-level light control	Depends on backlight
OLED Burn-In Risk	Yes	No OLED burn-in mechanism

Choose the Samsung G80SH if you want both 4K image quality and very high refresh rates, especially for a mixture of competitive and visually demanding games.

A conventional 4K 144Hz monitor may be sufficient if you primarily play slower-paced games or your PC cannot regularly exceed 144 FPS at your preferred settings.
