Quick verdict
The XG248QSG is the TN pick for players who want very high refresh rates and blur reduction without giving up variable refresh rate. Tom's Hardware found ELMB Sync paired strobing with Adaptive-Sync without a brightness penalty in that mode, while the separate ELMB 2 setting offers five pulse widths that trade brightness for clarity (about 40% dimmer at maximum). TFTCentral lists it among its top esports monitors.
It shares every TN limitation: 1080p on 24 inches, narrow viewing angles, and a picture that is only good for competitive games. Tom's Hardware's own conclusion was that most players would get better overall value from a 1440p OLED.

Buy it if
- You play competitive shooters at 500+ fps.
- You want strobing without giving up VRR.
- You like a solid stand with full adjustment.
Skip it if
- You rarely exceed 360 fps; a cheaper 360Hz to 400Hz monitor gives nearly the same result.
- You want one screen for all games; Tom's Hardware suggests a QHD OLED for overall value.
- You need USB ports.

Advantages and drawbacks
Advantages
- 600Hz native, 610Hz overclocked.
- ELMB Sync strobing works with Adaptive-Sync, per Tom's Hardware.
- About 450 nits SDR and accurate color for a TN.
- Sturdy stand with full adjustment.
Drawbacks
- Needs very high frame rates to benefit.
- TN viewing angles; 1080p resolution.
- No USB ports; ELMB 2 at maximum cuts brightness by about 40%.
What independent testing reports
| Metric | Reported result | Conditions | Source |
|---|---|---|---|
| SDR brightness | About 450 nits | Peak SDR | Tom's Hardware, October 25, 2025 |
| Brightness drop at maximum ELMB | About 40% | Strongest ELMB pulse setting versus off | Tom's Hardware, October 25, 2025 |
These are third-party results, not our tests. Different outlets use different methods, so compare numbers only within the same source.
Motion, response, and latency
ELMB Sync strobes the backlight while Adaptive-Sync is active, which most DyAc and ULMB implementations cannot do. Tom's Hardware reported no brightness penalty in ELMB Sync, while the stronger ELMB 2 pulse settings reduce blur further but dim the image by about 40% at maximum and showed occasional tearing. At 610Hz each frame lasts about 1.6 ms on a sample-and-hold display. Tom's Hardware reached around 525 fps in Doom Eternal with a top-tier GPU, which shows how demanding full use of this refresh rate is.
Image quality and HDR
Tom's Hardware measured about 450 nits in SDR and found color accurate for a TN, with a wider-than-usual gamut. It is still a TN panel with limited viewing angles, and DisplayHDR 400 is not meaningful HDR.
Connectivity, PC, and console notes
DisplayPort 1.4 with DSC for 610Hz, two HDMI 2.1 ports, and a headphone jack. There are no USB ports.
Warranty and ownership
As an LCD, no burn-in concern. US warranty terms not verified.
Warranty: Unknown (not verified for the US)
Alternatives worth comparing
BenQ ZOWIE XL2586X+
24.1″ · 1080p · 600Hz · TN (Fast TN)
600Hz with DyAc 2 and ZOWIE ergonomics, but no VRR while strobing.
ASUS ROG Strix Pulsar XG27AQNGV
27″ · 1440p · 360Hz · IPS (Fast IPS (AU Optronics M270DAN10.6, per TFTCentral))
27-inch 1440p 360Hz IPS with Pulsar strobing and VRR, for NVIDIA GPUs.
Questions buyers ask
Does 610Hz require a special cable?
Use DisplayPort 1.4 or newer; Tom's Hardware notes DSC is used to reach 610Hz.
Final recommendation
Choose the XG248QSG if you want strobing and VRR together at the highest refresh rate. If you do not need VRR while strobing, ZOWIE's DyAc 2 models are the alternative; if you want a better all-round picture, look at a 1440p OLED.
