Dual-mode monitors explained: 4K 240Hz, 1080p 480Hz, and every 2026 model
A dual-mode monitor trades resolution for refresh rate at the press of a button. Here is how it works, who benefits, and the full list of 2026 models.
Dual mode (LG calls it Dual-Hz) is the biggest gaming-monitor trend of 2026. One monitor offers a high-resolution mode for detail and a lower-resolution mode for speed: 4K at 240Hz or 1080p at 480Hz, 5K at 165Hz or 1440p at 330Hz, and even 1440p at 540Hz or 720p at 720Hz.
How dual mode works
In the lower-resolution mode, the monitor drives each block of pixels as a single pixel: a 4K panel showing 1080p groups pixels two by two. With a quarter of the pixel data to update, the panel and its scaler can refresh far faster. The image still fills the screen, but at a lower effective pixel density, so it looks softer.
Switching usually takes a button press or a menu setting, plus a few seconds for the signal to resync. On the LG 32GS95UE, for example, the button sits under the bottom bezel.

What GPU do you need for each mode?
The fast mode only helps if your graphics card can render that many frames. Esports games like Counter-Strike 2 and Valorant reach 400 to 500 frames per second on high-end GPUs at low settings; most single-player games will not get close. The high-resolution mode is the opposite problem: 4K at 240Hz or 5K at 165Hz takes a top-tier card in demanding games, and upscaling such as DLSS or FSR does a lot of the work.
Ports and bandwidth
LG's GX9 and GM9 and ASUS's PG32UCWM have DisplayPort 2.1 inputs, which carry more data than DisplayPort 1.4 or HDMI 2.1. LG notes that its 330Hz modes depend on GPU support. Other models, including the 32GS95UE and the XG32UQWMS, reach their top modes over DisplayPort 1.4 with Display Stream Compression, which is visually lossless for most people.
Who should buy a dual-mode monitor
- Buy one if you play both detailed single-player games and competitive shooters on one screen.
- Skip it if you only play esports: a native 1440p 500Hz-class OLED is sharper at speed. See our LG 27GX790B vs Odyssey OLED G6 comparison.
- Skip it for consoles: PS5 and Xbox Series X top out at 120Hz, so the fast mode does nothing for them.
- Mac users get the 5K modes' sharp text; the fast modes are a Windows gaming feature.
Questions we get
What is a dual-mode monitor?
A monitor that can run at two resolution and refresh-rate combinations, such as 4K at 240Hz or 1080p at 480Hz. In the lower-resolution mode the panel drives groups of pixels as one, which lets it refresh roughly twice as fast. You switch modes with a button or the on-screen menu.
Is a dual-mode monitor worth it?
If you split time between high-detail games or work and competitive esports, yes: you get a sharp high-resolution screen and a very fast low-resolution one in a single monitor. If you only play esports, a native 1440p 500Hz-class monitor is sharper at high refresh. If you never play fast shooters, the second mode adds nothing.
Does 1080p dual mode look blurry on a 32-inch monitor?
It looks soft. 1080p on a 32-inch screen is about 69 pixels per inch, well below the roughly 140 ppi of 4K at that size. Competitive players accept it for motion clarity, but for anything else you will want to switch back to 4K.
Do I need DisplayPort 2.1 for a dual-mode monitor?
Not strictly. Many dual-mode monitors reach their top modes over DisplayPort 1.4 or HDMI 2.1 using Display Stream Compression. DisplayPort 2.1 (UHBR13.5 or UHBR20) gives more bandwidth headroom, and on some models it is what unlocks the highest refresh rate with full color depth. Check the manual for which input supports each mode.
