Best dual-mode monitor

The ASUS ROG Swift PG32UCDP is the best dual-mode monitor for a PC that alternates between detailed 4K games and competitive play. Its OLED panel switches from 3840 by 2160 at 240Hz to 1920 by 1080 at 480Hz. It was £738.83 on Amazon UK at the time of writing (October 2026). The Samsung Odyssey G7 G70F is a cheaper IPS alternative: 4K 180Hz or Full HD 360Hz, at £429.00. Both make the resolution trade explicit rather than relying on software scaling.

LG's official page confirms the ASUS-style 4K/Full HD modes for the PG32UCDP, while Samsung describes the G70F as 4K 180Hz or FHD 360Hz. Those are not identical: Samsung tops out 60Hz lower in either mode. For a fixed-rate alternative, LG's UltraGear comparison lists the OLED GX7 at QHD 480Hz, while Gigabyte lists the FO27Q5P at QHD 500Hz.

What does dual mode change on a monitor?

Dual mode changes how many pixels the monitor displays and how often it can refresh them. At 4K, 3840 by 2160 equals 8,294,400 pixels per image. Full HD, 1920 by 1080, equals 2,073,600. The 4K mode therefore contains exactly four times as many pixels. The monitor's internal scaler and panel operate at a different resolution and refresh pairing when the owner switches modes in the on-screen menu.

That trade suits two different gaming jobs. 4K 240Hz prioritises detail for graphically rich games, cinematic adventures and general desktop work. Full HD 480Hz prioritises fast screen updates in games such as Counter-Strike 2 or Valorant, where players may prefer the higher frame rate to fine textures. Samsung's G70F has a comparable concept, but pairs 4K 180Hz with Full HD 360Hz. In either case, the PC must deliver frames that approach the display's ceiling.

Dual mode does not create detail in the fast setting. On a 32-inch 4K panel, Full HD uses one quarter of the native pixel count, so it can look softer than native 4K. Some monitors offer a smaller 24.5-inch or 27-inch image area in the lower-resolution mode to maintain pixel density and reduce the field of view. ASUS PG32UCDP supports aspect control and image-size options; use its manual to select the option that suits the game.

A fixed 480Hz or 500Hz QHD OLED keeps the higher pixel count while refreshing rapidly, which is a different solution. The LG UltraGear OLED GX7 is 2560 by 1440 at 480Hz; Gigabyte AORUS FO27Q5P is QHD at 500Hz. Those options do not have the resolution toggle of the ASUS, but a QHD image has 78% more pixels than Full HD. That can make menus and scenery sharper while still reducing the workload versus 4K.

Dual mode also affects the required graphics hardware. A game running at 4K has to render four times the pixel count of Full HD before effects are considered. Lowering the resolution can improve frame rates when the GPU is the limit. It does not fix a processor bottleneck, unstable frame pacing or network latency. A benchmark in the exact title and settings is more useful than assuming every esports game will run at 480 fps.

Which dual-mode monitor should you buy?

ASUS ROG Swift PG32UCDP is the top choice if you want the widest rate range: 4K 240Hz for quality, Full HD 480Hz for speed. It was £738.83 on Amazon UK in October 2026. Samsung Odyssey G7 G70F costs £429.00 and gives 4K 180Hz or Full HD 360Hz, a more affordable dual-mode route for a PC that does not need 480Hz. ASUS costs £309.83 more, or 72.2% over Samsung's verified price. The extra money buys OLED, 4K 240Hz and an 80Hz higher Full HD ceiling.

Samsung G70F was £429.00 at the same snapshot and has a different panel type, IPS. Its 4K mode tops out at 180Hz, and its FHD mode tops out at 360Hz. For players who never change resolution, Gigabyte FO27Q5P at £738.98 offers 500Hz QHD QD-OLED with DisplayPort 2.1. LG GX7 at £589.97 trades QD-OLED for WOLED and a 480Hz ceiling. Price alone cannot compare a dual-mode OLED with a fixed-rate monitor; decide whether the switch itself will be used.

Look at desk size before settling on 32 inches. A 31.5-inch 4K panel gives high pixel density and comfortable window tiling, while a 27-inch monitor can be easier to scan in fast play. The Samsung G70F is 27 inches. Its 4K image is about 163 ppi, far denser than its Full HD image at roughly 82 ppi. ASUS 31.5-inch 4K gives about 140 ppi, while Full HD mode drops to around 70 ppi. These calculations use the active diagonal and pixel dimensions; they illustrate the sharpness trade, not measured viewing comfort.

What are the downsides of dual mode?

The lower-resolution mode may look soft on a large panel, particularly if the image fills a 32-inch display. A smaller 24.5-inch simulated display area can make the same Full HD resolution look denser, but it reduces the visible image size and may leave black borders or unused screen area. Check the monitor's image-size feature and try it in a game before assuming that 480Hz will suit your preferences.

Switching modes takes menu access or a shortcut. ASUS says its PG32UCDP can switch through its on-screen display or an LG Switch shortcut; Samsung provides a Dual Mode setting. The change can involve resolution, refresh limit, aspect ratio and sometimes game-specific display configuration. A user who only plays one genre may never switch and could prefer a fixed 4K or QHD monitor with better value for that one use.

Dual mode does not increase a console's limits. PS5 and Xbox Series X support up to 4K 120Hz over compatible HDMI 2.1 connections. The console cannot use a 480Hz mode, and a 360Hz FHD monitor feature does not make a console render 360 fps. A dual-mode screen remains compatible when set to a supported input mode, but make sure the monitor accepts 4K 120Hz from the console over HDMI.

HDR can behave differently between modes and inputs. High refresh rates at high resolution require substantial bandwidth, and some monitors use Display Stream Compression. Verify the exact colour depth and HDR options in the manual. A cable that works at 4K 60Hz may not support the monitor's maximum 4K refresh. The system's GPU output and the monitor's selected port must both support the requested mode.

What PC can run a dual-mode display?

For 4K 240Hz, use a high-end graphics card and check game-specific benchmarks. Maximum refresh is not a target every title can sustain at native resolution, especially with ray tracing. Upscaling technologies can raise performance by rendering at a lower internal resolution, but the quality depends on the game and mode. The PC also needs a display output compatible with 4K 240Hz at the chosen colour format.

For Full HD 480Hz, the lower pixel count helps the GPU, but CPU performance often becomes the limit in esports titles. At 480 fps, a game engine must deliver a frame every 2.08ms. A PC averaging 480 fps with dips to 200 may feel less consistent than one holding 360 fps steadily. Check 1% lows and frame-time graphs, not just an average. A stable 240 fps is already excellent; the fast mode is valuable only if the player and game use the extra headroom.

Connectivity is model-specific. ASUS PG32UCDP lists HDMI 2.1 ports and DisplayPort 1.4 with DSC. Samsung G70F has HDMI 2.1 and DisplayPort 1.4. Gigabyte FO27Q5P uses DisplayPort 2.1 UHBR20 and HDMI 2.1. DisplayPort 2.1 does not make one screen faster unless the specific signal mode needs its bandwidth. Confirm the manual's mode table and graphics-card connectors before buying.

OLED care and warranty should be considered for ASUS PG32UCDP. Its OLED Care functions help reduce image retention, but work users should check the manufacturer's full warranty terms and follow its panel-protection prompts. Samsung G70F is IPS, a less delicate choice for long static desktop sessions. The difference in panel material makes it a plausible choice for users who value mode flexibility and work resilience more than black levels.
