If you want a newer, faster screen rather than an exact 300Hz model, ASUS’s ROG Swift OLED PG27AQWP-W runs at 540Hz at 1440p and also offers a 720Hz mode at 1280×720. That OLED is a different, more demanding and higher-risk ownership choice—not a 300Hz monitor.
For a US price reference, ASUS’s store displayed the XG27AQMR at $449 in the available page snapshot; that is an observed price, not a guaranteed current price or availability. Check the ASUS product page for current regional availability. Specs and connection limits below are based on ASUS’s XG27AQMR specifications.

Best exact 1440p/300Hz monitor: ASUS ROG Strix XG27AQMR
The XG27AQMR is the clearest recommendation when 300Hz is a firm requirement. It combines a 27-inch, 2560×1440 Fast IPS panel with a stated 300Hz maximum refresh rate. ASUS lists a 1ms GTG response-time claim, Adaptive-Sync, G-SYNC Compatible operation, FreeSync Premium Pro, and ELMB Sync. The response-time figure is a manufacturer rating, not an independent measurement of every pixel transition or total input latency.
#1 Best Overall
- High-Resolution QHD Gaming Display: 27-inch QHD (2560x1440) gaming monitor with 300Hz refresh rate designed for professional gamers and immersive gameplay
- Fast IPS Technology with Rapid Response Time: ASUS Fast IPS technology enables a 0.3ms (GTG) response time(min.) for sharp gaming visuals with high frame rates
- Advanced Motion Blur Reduction: ASUS Extreme Low Motion Blur Sync (ELMB Sync) technology enables ELMB and variable-refresh-rate technologies to work simultaneously to eliminate ghosting and tearing for sharp gaming visuals
- Convenient Settings Management: DisplayWidget Center enables easy monitor settings adjustments with a mouse
- Enhanced Dark Scene Visibility: Shadow Boost enhances image details in dark areas, brightening scenes without over-exposing bright areas
Why it fits competitive PC gaming
QHD gives more desktop and in-game detail than 1080p at the same screen size, while 300Hz can make rapid camera motion and tracking feel smoother when the PC delivers high frame rates. Fast IPS also avoids OLED burn-in as a central ownership concern and is generally a more straightforward choice for static desktop use.
ASUS specifies 1000:1 typical contrast, 350 cd/m² typical brightness, and 600 cd/m² HDR peak brightness. Those figures do not make it equivalent to an OLED for black levels or HDR contrast. In a dark room, IPS blacks can look gray, and glow or backlight bleed can vary by unit.
Who should skip it
- Console buyers seeking 1440p/300Hz: ASUS lists the HDMI inputs at up to 1440p/144Hz.
- Players whose games usually run well below roughly 180–200fps, for whom a less expensive 240Hz screen may make more sense.
- Buyers chiefly seeking deep blacks and high-impact HDR, who may prefer OLED and accept its trade-offs.
- Players of demanding cinematic games who value image quality or price more than very high frame rates.
See the official specification page for signal and feature details.
Faster alternatives: 540Hz and 480Hz OLED
ASUS ROG Swift OLED PG27AQWP-W: 540Hz at QHD
The PG27AQWP-W is the more ambitious alternative for buyers who want to go beyond 300Hz. ASUS lists 2560×1440 at 540Hz and a dual-mode 1280×720 setting at 720Hz, plus Tandem TrueBlack Glossy OLED, DisplayPort 2.1, OLED Care Pro, and a proximity sensor. The advertised 0.02ms GTG response time is a manufacturer claim; it should not be read as a universal real-world latency result.

Its OLED panel can provide per-pixel black levels and very fast transitions, but it costs more in ownership considerations: long-term burn-in risk, brightness behavior, reflections from a glossy surface, and text appearance all matter. It is also difficult to exploit 540fps at native QHD in demanding games. Independent coverage is available in the RTINGS PG27AQWP-W review; RTINGS says the review was updated to Test Bench 2.1.2 on March 17, 2026. RTINGS also lists it among leading options in its best 1440p gaming monitors coverage.
ASUS ROG Swift OLED PG27AQDP: 480Hz at QHD
The PG27AQDP is a 1440p 480Hz WOLED alternative with a manufacturer-stated 0.03ms GTG claim, DisplayHDR 400 True Black, G-SYNC Compatible support, OLED Care+, and a custom heatsink. Consider it as a high-refresh OLED—not an exact-300Hz pick—and judge its value against the newer 540Hz option using live local pricing. Its specifications are listed on the ASUS PG27AQDP page.
When a 240Hz or 360Hz screen is the better buy
A good 240Hz QHD monitor can be a better-value fit if your PC cannot regularly exceed 200fps, or if you prioritize OLED contrast over the last increment of refresh rate. Some 360Hz QHD OLED and IPS models may also be better-balanced alternatives, but model-specific pricing, availability, and performance are not established here. RTINGS’ 1440p monitor guide discusses 240Hz OLED examples including the Dell Alienware AW2726DM and HyperX OMEN OLED 27q; verify their current specifications and local availability before buying.
What 300Hz changes—and what it does not
At 300Hz, a refresh interval is about 3.33ms. At 240Hz it is about 4.17ms, and at 360Hz about 2.78ms. The 240-to-300Hz step is real but much smaller than moving from 60Hz to 144Hz. It is most useful in fast competitive play when frame delivery is high and consistent.

Refresh rate is only one part of motion clarity and responsiveness. Pixel transitions, overdrive tuning, overshoot, VRR behavior, display processing, game-engine timing, GPU load, CPU limits, and the render queue all affect the result. A well-tuned 240Hz OLED can look clearer in motion than a poorly tuned 300Hz IPS screen. A 540Hz panel running a game at 150fps does not turn that game into a 540fps experience.
Adaptive sync can smooth fluctuating frame delivery within the display’s supported range, but it does not create extra rendered frames. Total system latency also includes the mouse or controller, game processing, GPU workload, drivers, and sync settings. A monitor alone cannot guarantee a competitive advantage.
Fast IPS versus OLED for gaming and desktop use
| Consideration | Fast IPS, such as XG27AQMR | OLED, such as PG27AQWP-W or PG27AQDP |
|---|---|---|
| Motion | Can perform well with suitable overdrive; check independent response and overshoot testing | Very fast pixel transitions can deliver especially clear motion |
| Contrast and dark-room blacks | Lower native contrast; blacks can look gray | Per-pixel illumination enables deep blacks and strong dark-scene contrast |
| HDR | Certification and peak brightness do not overcome limited native contrast | Strong contrast can improve HDR impact; brightness behavior varies by content and protection features |
| Static desktop use | Generally lower concern about permanent image retention | Burn-in remains a long-term consideration; pixel-care features and warranty terms matter |
| Text and screen surface | Typically familiar IPS pixel behavior; unit uniformity can vary | Text clarity and reflections depend on pixel layout and coating |
For OLED, check warranty coverage for burn-in, pixel-refresh behavior, automatic brightness limiting, and how much static desktop content you use. Burn-in is a risk to manage, not an inevitable outcome. For IPS, inspect the return and dead-pixel policy because glow and backlight uniformity can vary between units.

Use DisplayPort for the XG27AQMR’s full refresh rate
ASUS specifies DisplayPort 1.4 with DSC for 2560×1440 at 300Hz. Its HDMI inputs are listed up to 1440p/144Hz, so HDMI is not the route to the full refresh rate on this model. Use the supplied cable where possible, connect the graphics card directly to the monitor, and verify that the GPU output supports the required DisplayPort mode and DSC.

Rendering 300fps is different from outputting a 300Hz signal
A graphics card may send a 300Hz-capable signal while a game renders far fewer than 300 frames per second. Esports titles at competitive settings are more likely to approach that frame rate than demanding AAA games at native 1440p. Results depend on the game, CPU, GPU, graphics settings, upscaling, frame generation, and whether you care about average frame rate or 1% lows. No single GPU recommendation applies across all games and settings.
For the PG27AQWP-W, ASUS specifies DisplayPort 2.1; the PC must still render enough frames to benefit from the 540Hz mode. Laptop output limits and adapters can also restrict available modes. Confirm the port path and the selected display mode rather than assuming any DisplayPort connection can provide every resolution and refresh combination.
Set up and troubleshoot the XG27AQMR
- Connect the PC to DisplayPort. Use the GPU’s DisplayPort output, connect directly where possible, and select the matching monitor input. HDMI is specified only up to 1440p/144Hz on this display.
- Select 300Hz in Windows. Open Settings > System > Display > Advanced display, choose the XG27AQMR, and select 300Hz if offered. If it is missing, check the cable, GPU port, drivers, and monitor’s DisplayPort mode.
- Enable adaptive sync if useful. Turn on the monitor’s Adaptive-Sync option and configure G-SYNC Compatible or FreeSync in the GPU software. Check behavior in your games rather than assuming all modes and refresh rates work identically.
- Test overdrive instead of automatically choosing the highest setting. Compare response-time options at several frame rates. An aggressive mode can cause overshoot or inverse ghosting.
- Try ELMB Sync separately. ASUS lists ELMB Sync, but blur-reduction strobing and VRR can have compatibility limitations. Compare VRR for variable frame rates with strobing at stable frame rates; do not assume every feature works simultaneously in every mode.
- Check the game’s frame cap and performance. Remove an unintended 144Hz, 165Hz, or 240Hz cap if appropriate, then check actual frame rate and frame-time consistency. A 300Hz desktop setting does not mean the game is rendering 300fps.
- Set SDR and HDR deliberately. Calibrate SDR separately; enable HDR for supported content and assess it in a game with a sound HDR implementation. IPS contrast can make HDR look less dramatic than expected.
If the screen appears blurry
- Compare overdrive levels for overshoot and trailing.
- Check actual game frame rate; low frame delivery can look blurred despite a 300Hz desktop mode.
- Distinguish display motion blur from blur or smearing produced by the game itself.
- Test ELMB and VRR as separate configurations if their behavior is unsatisfactory together.
If HDR looks worse than SDR
- Confirm the game supports HDR and that its HDR settings are configured correctly.
- Check Windows HDR and monitor picture modes; enabling HDR for SDR desktop content may not improve the image.
- Keep expectations aligned with the panel: DisplayHDR 600 certification does not provide OLED black levels.
Which 1440p high-refresh monitor should you buy?
- Choose the XG27AQMR if you specifically want native 2560×1440 at 300Hz, prefer IPS’s simpler static-use profile, and can connect over DisplayPort.
- Consider the PG27AQWP-W if you want 540Hz at QHD, value OLED contrast and motion, and accept the hardware demands and OLED ownership trade-offs.
- Consider the PG27AQDP if a 480Hz OLED fits your priorities and its current local price is compelling relative to newer options.
- Choose a strong 240Hz model if your games and PC rarely sustain high frame rates, or if a better panel or lower cost matters more than moving from 240Hz to 300Hz.
Availability and pricing vary by country and retailer. The XG27AQMR is the exact-match recommendation; the OLED models are faster alternatives, not substitutes for the literal 300Hz specification.
