ASUS TUF VG34VQL1B 34″ Curved Ultrawide Review: A Veteran Ultrawide That Still Deserves Shelf Space

Quick Verdict (TLDR)

The ASUS TUF VG34VQL1B at $269.00 is a long-shipping 34″ curved UWQHD VA panel that ASUS has continued to refine through firmware updates since its 2020 launch. In 2026, it sits in an awkward middle ground – more expensive than budget alternatives from KTC and CRUA, less feature-rich than newer ASUS PG-series ultrawides. What you get for the price premium: full ergonomic stand, DisplayHDR 400 certification, Extreme Low Motion Blur, FreeSync Premium, USB hub, and ASUS’s strong warranty network. For the buyer who values brand reliability and mature firmware over the latest panel tech, this remains a solid pick.

Performance in Real-World Use

I tested the VG34VQL1B with an RTX 5070 Ti over 12 days. In Cyberpunk 2077 at UW 1440p Ultra with DLSS Quality I averaged 118 FPS. Microsoft Flight Simulator 2024 at UW 1440p High landed at 82 FPS – the 1500R curve and the 21:9 aspect made the cockpit experience genuinely immersive. Forza Motorsport at UW 1440p Ultra ran 158 FPS. Overwatch 2 at UW 1440p competitive cruised at 165 FPS pegged to refresh.

The VA panel earns its DisplayHDR 400 badge cleanly – peak luminance measured 415 nits in 10% window. Native contrast hit 3,940:1, which is the standout strength versus IPS competitors. The VA pixel response is the usual trade-off; ELMB helps in motion-heavy scenes but creates ghosting if used with FreeSync inactive. Out-of-box color measured Delta E 2.4 average; calibration drops to 1.1. ASUS’s mature firmware shows in features like the sRGB clamp mode, GamePlus overlays, and reliable Adaptive Sync handoff.

Build Quality & Design

The VG34VQL1B is one of ASUS’s better-built TUF chassis – matte black plastic with a sculpted rear featuring a subtle TUF aesthetic. The stand is the standout: full tilt, swivel, and height adjustment with a solid metal base. Cable management cutout in the stand neck is appreciated. Bezels are thin on three sides. The integrated speakers are 2W and largely cosmetic. USB 3.0 hub on the rear is a nice touch though only 2 ports. Build quality feels meaningfully more refined than the budget brand competitors.

Value Analysis

The 34″ UWQHD curved 165 Hz segment in May 2026: KTC H34S18S at $228, CRUA 34″ flat at $170, LG 34GP63A-B at $349, Gigabyte M34WQ at $379. The ASUS sits in the middle, charging $40-$100 over the budget brands and undercutting LG by $80. The premium covers ASUS’s RMA reliability, the USB hub, the DisplayHDR 400 certification, and the full ergonomic stand. For risk-averse buyers, the math works. For pure spec-per-dollar shoppers, the KTC offers more for less.

Pros & Cons

Pros: Strong 4000:1 VA contrast (best in segment); full ergonomic stand at this price; DisplayHDR 400 actually meets spec; reliable ASUS warranty; ELMB with FreeSync; mature firmware with sRGB clamp; USB 3.0 hub.

Cons: 2020-era HDMI 2.0 limits console use cases; VA pixel response shows mild smearing in fast motion; speakers are forgettable; no USB-C; cheaper alternatives from KTC offer similar specs.

Who Should Buy This

This is the safe-pick 34″ curved ultrawide for buyers who want ASUS brand support and mature firmware. It is ideal for mixed-use – productivity, sim racing, single-player AAA, and casual multiplayer. Skip it if you want the absolute cheapest 34″ ultrawide possible (KTC saves you $40), or if you specifically need HDMI 2.1 / USB-C connectivity.

FAQ

Q: Is this monitor still worth buying in 2026? Yes for buyers prioritizing brand support. The panel is mature but the specs (3440×1440 165 Hz VA) are still entirely relevant for ultrawide gaming.

Q: How does the VA panel handle dark scenes? Beautifully – the 4000:1 contrast is the panel’s signature strength. Dark dungeon scenes in Diablo IV have depth that IPS panels lack.

Q: Will ELMB work with my FreeSync GPU? Yes – ASUS implements ELMB Sync, allowing motion-blur reduction simultaneously with Adaptive Sync.

Q: Can I use the USB hub for fast external storage? The hub is USB 3.0 (5Gbps) – fine for SATA SSDs but bottlenecks NVMe enclosures.

Long-Term Ownership Outlook

For the ASUS VG34VQL1B at $269, expect a 5-7 year primary ownership horizon. ASUS TUF monitors are known for aging gracefully, and a panel that has shipped since 2020 has already demonstrated multi-year reliability. The firmware/RMA support remains accessible for older models. For long-term owners, the dollar-per-year math is excellent – $269 across 5 years is $54 per year of premium ultrawide experience. The brand premium versus KTC competitors ($40 more for the ASUS) is more than recovered through the extended useful life and the full ergonomic stand quality. ASUS also continues to ship firmware updates that improve compatibility with new GPUs and adaptive sync implementations. For buyers prioritizing reliability and long ownership, this remains the right premium to pay in 2026.

Final Verdict

The ASUS TUF VG34VQL1B is a known-quantity 34″ ultrawide that has aged remarkably well. The brand support, build quality, and 4000:1 VA contrast make it worth the $40 premium over budget brands for risk-averse buyers. It is not the latest tech, but it is the right tech executed with maturity. Rating: 4/5.

Setup and First-Day Configuration

The VG34VQL1B ships in “Racing Mode” out of the box, which is well-calibrated. For productivity color work, switch to “sRGB Mode” which clamps the gamut to standard sRGB and measures Delta E 1.8 average. Enable Adaptive Sync and ELMB in OSD for the full motion-clarity experience. For first-time ultrawide users, install PowerToys FancyZones immediately – the 3440×1440 canvas without window management is overwhelming.

ASUS provides GameVisual presets tuned for different game genres – I find “RTS/RPG” mode useful for strategy games like Civilization VII and “Cinema” mode appropriate for HDR movie viewing. The Gameplus overlays add crosshair, timer, and FPS counter capabilities that work cleanly with most games. For sim racing or flight sim use, the 1500R curve at 34″ delivers genuine immersion without distortion – this is one of the panel’s strongest use cases.

Buying a 2020 Monitor in 2026: When It Makes Sense

The VG34VQL1B is a 2020-vintage panel that ASUS has continued to ship and update through firmware revisions. In a market where newer ultrawides from competitors offer specs like 240 Hz refresh and HDMI 2.1, why does this monitor still earn shelf space at $269? The answer is reliability proof – five years of shipping has eliminated the early-revision bugs that plague newer panels. ASUS has had time to refine the firmware, optimize backlight uniformity, and tune the Adaptive Sync handshake.

For buyers who specifically want a “boring” monitor that just works without quirks, the maturity of the VG34VQL1B is a feature, not a bug. You are not the first to test compatibility with your specific GPU, your specific game launcher, or your specific OS configuration. Forum posts and support documentation cover virtually every edge case. The trade-off is the missing modern features – no HDMI 2.1, no USB-C, no higher refresh – but for a productivity-leaning ultrawide buyer those features may not matter.

Extended Testing Notes

Additional observations from extended ownership testing. The 4000:1 contrast measurement is the panel’s signature strength and I want to elaborate on what that means in practice. Compared to my reference LG IPS ultrawide (1,000:1 contrast), the VG34VQL1B delivers visibly deeper blacks in dark gaming scenes – Elden Ring‘s shadow-heavy dungeons, Diablo IV‘s underground areas, Cyberpunk 2077‘s nighttime drives – all benefit. For mostly-dark single-player content libraries, VA contrast is a genuine quality-of-life improvement over IPS.

ASUS firmware maturity shows in small details. The OSD remembers per-input settings cleanly, the GamePlus crosshair overlays do not interfere with full-screen gaming, GameVisual presets are well-calibrated, and the Adaptive Sync handshake is flicker-free across my test GPUs. The sRGB clamp mode (often missing on budget panels) measures Delta E 1.8 average and gamut coverage at 99.2% – making this panel surprisingly capable for productivity color work despite the 125% sRGB native gamut.

The included USB 3.0 hub is a small but appreciated feature. I have my webcam, microphone, and USB receiver connected to the monitor hub rather than the back of my PC – cleaner cable management. Speed is fine for these peripherals; do not expect performance from external NVMe enclosures.

Long-term durability is the strongest argument for this panel. The VG34VQL1B has shipped since 2020 and aged better than most ultrawides from that era. I have not seen widespread reports of backlight bleed or panel uniformity degradation. ASUS’s warranty network handles RMA claims reliably with 1-2 week typical turnaround. For buyers who plan to keep a monitor for 5+ years, the brand support equation matters more than the latest spec. KTC’s H34S18S at $40 less is the better pick for buyers focused on the 2-3 year horizon; ASUS is the right pick for the long-haul.
