Summary

The Sceptre C345B-QUT168 is aimed at users who want a large ultrawide canvas without stepping into premium price tiers. It pairs a 34″ WQHD (3440×1440) VA panel with a 21:9 aspect ratio that increases horizontal workspace for multitasking and delivers immersive gaming scenes. The monitor’s strengths are its ultrawide WQHD resolution, high refresh rate (165Hz), fast 1ms MPRT response, and additional touches like LED backcover lighting and Picture-by-Picture (PBP).

Best for: multitaskers who want extra horizontal space, gamers who want high refresh and low motion blur, and creators who need a wider canvas for timelines and side-by-side windows.

Design and build quality

The monitor adopts a clean, machine-black finish with a subtle bezelless look along the front edge. The curvature provides a natural wrap for a single-user desktop setup, improving immersion for wide-format content and games. A standout design element is the luminous backcover light, which adds an ambient glow behind the panel and gives the monitor a modern flair.

Assembly is straightforward; the included stand offers tilt adjustment but no height or swivel. There is VESA compatibility for users who prefer a monitor arm or more ergonomic positioning. Build materials feel typical for this class — mostly plastic, with a sturdy enough base for stable placement.

Display performance

Sharpness and color

At 3440×1440, the pixel density on a 34″ VA panel gives noticeably sharper text and UI elements than 1080p ultrawides while maintaining a cinematic wide field for media. The advertised 99% sRGB coverage is suitable for general content creation, photo editing for web, and accurate color work that doesn’t require wide-gamut (Adobe RGB or DCI-P3) support.

Contrast and blacks

VA panels typically excel at contrast compared with IPS, and the C345B reflects that: blacks appear deeper and darker scenes gain more depth than typical IPS alternatives. This makes it a good choice for movie watching and gaming where contrast matters.

Motion handling and gaming

With a 165Hz refresh ceiling and a 1ms MPRT mode, motion clarity is strong for fast-paced gaming. AMD FreeSync Premium provides tear-free experiences when paired with compatible GPUs. Expect very little ghosting in MPRT mode, but note that MPRT can dim perceived brightness slightly because it uses strobing techniques.

Viewing angles

VA panels have improved viewing angles compared to older VA tech but still trail IPS in color consistency at extreme off-axis angles. The listed 178° spec is typical and fine for single-user setups; for multi-viewer setups where angle-critical color consistency is required, IPS may be preferable.

Connectivity and extras

Inputs include dual DisplayPort and dual HDMI ports, allowing multiple simultaneous connections (useful for console + PC). Picture-by-Picture (PBP) enables side-by-side sources — handy for streamers, multitaskers, or anyone running two systems in parallel.

Built-in speakers provide basic audio for casual use, but for richer sound use external speakers or headphones. The monitor also includes a blue light filter to reduce eye strain and supports tilt adjustment; there is no built-in height or swivel on the standard stand.

Pros and cons

What we like

  • Immersive 34″ 21:9 WQHD canvas — excellent for productivity and cinematic gaming
  • High refresh rate (up to 165Hz) and 1ms MPRT for smooth, low-latency gaming
  • VA contrast advantage produces deeper blacks and strong HDR-like feel for dark scenes
  • 99% sRGB is solid for general content creation and photo/video editing for sRGB-targeted work
  • Picture-by-Picture and multiple inputs make it flexible for multi-source setups
  • Attractive luminous backcover light for ambient aesthetic
Potential drawbacks

  • Stand only offers tilt — no height or swivel without VESA arm
  • VA panels can show some color/contrast shifts at extreme angles vs IPS
  • MPRT strobing can reduce perceived brightness for some users
  • Built-in speakers are functional but not a replacement for a dedicated audio setup

Who should buy this monitor?

  • Gamers who want a wide, immersive field with a fast refresh rate and minimal motion blur.
  • Professionals and power users who benefit from extra horizontal workspace for editing timelines or multi-window workflows.
  • Casual creators and photographers working within the sRGB color space.
  • Users who value aesthetics (LED backcover lighting) and built-in PBP functionality for multi-system workflows.

Conclusion

The Sceptre 34-inch Curved Ultrawide (C345B-QUT168) delivers a compelling mix of ultrawide productivity and gaming features. Its WQHD resolution, high refresh capability, 1ms MPRT response, and VA contrast give it broad appeal for both immersive gameplay and efficient multitasking. While it lacks more advanced ergonomics on the included stand and the speakers are basic, its core display performance and PBP flexibility make it a strong option for users wanting a wide-format monitor without moving into high-end premium pricing tiers.

If you need a large ultrawide for work and play, and you value contrast and motion clarity, the C345B-QUT168 is worth considering.
