Correction notice. An earlier version of this review described the XG2431 as a 2560×1440 QHD display. That was wrong. ViewSonic lists the XG2431 as a 24-inch Full HD (1920×1080) panel, and we have corrected the specification table, the comparison table and every resolution claim below. We are leaving the review published, with this note, rather than quietly deleting the mistake.
Why the XG2431 gets mistaken for a 2K monitor
Two things cause the confusion. First, 240 Hz is normally a flagship number, and flagship monitors are usually QHD or better — so people assume the resolution matches the refresh rate. Second, the XG2431 sits in ViewSonic’s XG gaming family alongside genuinely QHD models such as the XG272-2K, and the model numbers do not tell you which is which. The XG2431 reaches 240 Hz precisely because it is 1080p: fewer pixels per frame means a mid-range GPU can actually feed the panel.
Build Quality & Ergonomics
✅ Strengths
- Solid, wobble-free stand with broad rectangular base
- Full ergonomic adjustments: height, tilt, swivel, pivot
- Thin bezels on three sides — ideal for multi-monitor setups
- Matte anti-glare coating reduces reflections effectively
- Clean cable management channel integrated into stand
⚠️ Limitations
- Entirely plastic construction — no premium materials
- OSD buttons on rear are difficult to locate by feel
- No built-in speakers
- 24-inch panel size may feel small for productivity tasks
- Stand footprint is larger than average for the screen size
Display Performance: Panel & Color Accuracy
| Metric | Value | Rating |
|---|---|---|
| sRGB Coverage | ~99% | ⭐⭐⭐⭐⭐ |
| DCI-P3 Coverage | Not published by ViewSonic (sRGB-class 6-bit + FRC panel) | ⭐⭐⭐ |
| Delta E (out of box) | ~2.1 average | ⭐⭐⭐⭐ |
| Contrast Ratio | ~1000:1 (native IPS) | ⭐⭐⭐ |
| Black Level | Moderate (IPS glow present) | ⭐⭐⭐ |
| Peak Brightness | 350 cd/m² typical (DisplayHDR 400 tier) | ⭐⭐⭐⭐ |
| Uniformity | Good — minimal backlight bleed | ⭐⭐⭐⭐ |
The IPS panel on the XG2431 delivers vibrant, accurate colors right out of the box — making it competitive not just for gaming but also for casual creative work. Wide color gamut coverage is a clear highlight for a monitor positioned at this price point.
240Hz Performance & Competitive Gaming Testing
Motion Clarity & Response Time
- 🎯 Native 240Hz refresh rate is fully supported over DisplayPort, and ViewSonic’s signal table also lists 48–240 Hz over HDMI at 1080p
- 🎯 0.5ms MPRT response time eliminates trailing in fast-paced titles like CS2, Valorant, and Apex Legends
- 🎯 Overdrive settings (Ultra Fast / Fast / Normal / Off) allow user tuning without excessive overshoot
- 🎯 PureXP backlight strobing delivers exceptional blur reduction — this was the world’s first Blur Busters Approved 2.0 display
- 🎯 PureXP strobing and FreeSync cannot run simultaneously — a common hardware limitation
- 🎯 Input lag measured at approximately 1–2ms at 240Hz — imperceptible in competitive play
Refresh Rate vs. Resolution Trade-off
| Use Case | Suitable? | Notes |
|---|---|---|
| Competitive FPS (CS2, Valorant) | ✅ Excellent | 240 Hz + PureXP strobing is a significant advantage |
| Battle Royale (Warzone, Apex) | ✅ Excellent | 1080p keeps frame rates high, which is what 240 Hz needs |
| Single-player / RPG | ⚠️ Adequate | Colour is pleasant, but 1080p on 24 inches looks soft next to a QHD panel |
| RTS / Strategy | ⚠️ Adequate | 1080p gives you less usable desktop space for dense strategy UIs |
| Content Creation | ⚠️ Adequate | No factory calibration report; contrast is average |
HDR Implementation
What HDR10 Delivers
- Supports HDR10 signal input
- Activates a wider color gamut mode automatically
- Improves highlight detail in HDR-enabled titles
- Useful in games like Cyberpunk 2077 and Horizon series
HDR Caveats
- No local dimming — HDR contrast is limited
- Peak brightness is modest — ViewSonic rates the panel at 350 cd/m² typical, far short of true HDR standards (1000+ nits)
- DisplayHDR 400 certified — entry-level HDR tier
- SDR gameplay will look better on this panel than HDR for most users
HDR on the XG2431 is functional and adds some visual richness, but like most monitors at this tier, it should not be the primary purchase driver. The competitive gaming performance is the real story here.
ViewSonic XG2431 vs. Direct Competitors
| Model | Resolution | Refresh Rate | Panel | Blur Reduction | Price Range |
|---|---|---|---|---|---|
| ViewSonic XG2431 | Full HD (1920×1080) | 240Hz | IPS | PureXP (Blur Busters 2.0) | Mid-range |
| ASUS TUF Gaming VG27AQZ | QHD (2560×1440) | 165Hz | IPS | ELMB | Mid-range |
| LG 27GR75Q | QHD (2560×1440) | 165Hz | IPS | 1ms MBR | Mid-range |
| AOC Q27G3XMN | QHD (2560×1440) | 180Hz | Mini LED | None | Mid-range |
| BenQ MOBIUZ EX2710Q | QHD (2560×1440) | 165Hz | IPS | None | Mid-range |
The XG2431 is the odd one out in this table: it is the only Full HD panel here. That is exactly why it can hit 240 Hz at this price — pushing 1920×1080 is far cheaper for your GPU than pushing 2560×1440. If frame rate is all you care about it is a bargain, but it is not a 2K monitor, and the QHD models above will look visibly sharper on a desktop.

24 240Hz Gaming Monitor
This 24-inch 240Hz IPS monitor delivers smooth gaming and sharp everyday use at $95, making it the safest choice for budget-conscious gamers and office workers who want both speed and color accuracy. The trade-off is a flimsy plastic base that requires stabilization and limited height adjustment, issues that disappear with a monitor arm but add to the total cost.

Frequently Asked Questions
What size is the ViewSonic XG2431?
24 inches, with a 23.8-inch viewable area. At 1920×1080 that is roughly 93 pixels per inch — noticeably coarser than the ~109 PPI of a 27-inch QHD panel, so text and game UI look chunkier than on a true 2K display.
What refresh rate and sync technology does it support?
240 Hz with a 0.5 ms MPRT response (1 ms GtG with overdrive), AMD FreeSync Premium and NVIDIA G-Sync compatibility.
Does the XG2431 deliver proper HDR?
Yes, at the entry tier: ViewSonic certifies the XG2431 to VESA DisplayHDR 400 and it accepts HDR10. With no local dimming and 350 cd/m² typical brightness, though, treat HDR as a bonus rather than a reason to buy.
