Adaptive refresh is most useful when the correct standard, refresh setting and game profile work together. Optimising NVIDIA and AMD adaptive sync at 500Hz starts by proving QHD 500Hz operation, then enabling the graphics-platform path and watching how it behaves when frame rate moves. The R23,899 XG27AQDPG supports both ecosystems.

Quick Answer

Set the ASUS XG27AQDPG to 2560x1440 at 500Hz before changing sync controls. On a supported NVIDIA system, enable the G-SYNC Compatible path; on AMD hardware, configure FreeSync Premium Pro. Test each through its own graphics control panel and one repeatable game scene. Adaptive sync changes refresh timing around delivered frames, not the panel's maximum or the game's rendering speed.

🔌 Prove QHD 500Hz without sync

Connect the graphics card directly through an appropriate HDMI 2.1 or DisplayPort 1.4 route. Open the operating-system display controls and select QHD plus 500Hz. Confirm the monitor's information screen agrees. This baseline prevents a missing refresh option from being mistaken for an adaptive-sync fault.

Use Evetech's gaming display category to compare inputs, refresh ceilings and resolutions before assigning a cable.

Launch the game, select the same display and refresh value, and close any frame cap that was created for an older monitor while establishing the baseline. Record the original cap so it can be restored for later testing.

🟢 Configure the NVIDIA route

Enable the monitor's adaptive feature, then open the NVIDIA graphics controls and select the G-SYNC Compatible option for the XG27AQDPG. Apply it to the display mode you intend to use. Some games treat exclusive full screen and borderless windows differently, so test the actual mode used in competition.

Run a repeatable camera pan through a scene where frame rate changes. Look for tearing lines, uneven motion and sudden cadence shifts. Keep resolution and picture settings fixed while judging the sync change. A 0.03ms GTG panel can change pixels quickly, yet frame pacing still depends on when the GPU completes each image.

🔴 Configure the AMD route

On an AMD system, activate FreeSync Premium Pro in the appropriate graphics controls after confirming that the display is recognised. Use the same game route, scene and graphics preset chosen for the NVIDIA-style test. The labels and control panels differ, but the diagnostic principle is identical: compare one sync state while the rest of the chain remains stable.

The OLED monitor collection provides context for panel technology alongside adaptive-refresh support.

📈 Tune the frame relationship

The 500Hz ceiling does not require a constant 500fps for adaptive refresh to have value. Use a frame-rate overlay and record minimum behaviour as well as a headline average. Sharp drops often explain a stutter more clearly than the highest observed figure.

A measured frame cap can sometimes keep delivery within a more stable region. Compare uncapped performance with a cap that the system can sustain. Do not copy another player's number without testing the same game, GPU, processor and settings.

🌈 Keep picture controls out of the first pass

Leave HDR, colour presets and shadow controls unchanged while proving sync. The QD-OLED panel supports DisplayHDR 500 True Black and 99% DCI-P3, but picture calibration introduces separate variables. Once motion is stable, build an HDR preset and confirm that it does not change the game's display mode.

OLED Anti-Flicker 2.0 is part of the monitor's feature set. If visible flicker remains, note whether it follows a particular frame-rate swing, menu, cable or sync state. Change only one item before repeating the scene.

The curved gaming monitor range can help buyers compare shape decisions without confusing them with the sync standard.

🧾 Save two platform baselines

Record input, resolution, refresh, graphics driver, sync label, display mode, frame cap and game preset. If the PC later changes from NVIDIA to AMD or vice versa, rebuild the corresponding path rather than assuming the old control-panel choice carries over. The physical monitor supports both standards, but only the installed platform's route is active during a session.

🧪 Compare timing without changing the picture

Create a short route with a constant-speed pan, a rapid turn and a scene that causes a predictable frame-rate drop. Run it once with the platform's adaptive sync disabled, then enable G-SYNC Compatible or FreeSync Premium Pro and repeat. Keep QHD, refresh, HDR state, picture preset and game quality identical. Record tearing, cadence and frame-time spikes as separate observations.

If uncapped output repeatedly crosses a wide range, test a cap the system can sustain through the busiest part of the route. The goal is not to make the frame counter resemble the 500Hz label; it is to establish consistent motion with the shortest practical delay for that game. Save the cap beside the sync setting instead of copying it to every title.

After a driver update, confirm that the monitor remains selected in the correct control panel and that the game has not changed from exclusive full screen to borderless or another mode. Then rerun only the short route. This small regression test catches a lost adaptive-sync configuration before a match and keeps platform changes distinct from QD-OLED picture adjustments.

Frequently Asked Questions

Which adaptive-sync standard does this monitor support?

It supports G-SYNC Compatible and FreeSync Premium Pro.

What should I configure before adaptive sync?

Confirm the intended HDMI 2.1 or DisplayPort 1.4 connection and select QHD at 500Hz.

Do NVIDIA and AMD use the same control panel?

No. Each graphics platform exposes its own adaptive-refresh controls.

Will adaptive sync increase the monitor's maximum refresh rate?

No. It coordinates refresh timing within the display's operation; it does not raise the 500Hz ceiling.

How can I judge whether the setting is working?

Repeat a known camera movement while watching tearing, cadence and frame delivery with other settings held constant.

Is this dual-platform 500Hz display expensive?

The XG27AQDPG costs R23,899 and combines QHD 500Hz QD-OLED with both adaptive-sync routes.
