The Sceptre C355W-3440UN is a 35″ curved ultra-wide monitor with 3440 × 1440 resolution at 100Hz, supporting AMD Freesync and G-Sync. The Sceptre C355W is aimed at gamers, as are other models that have become quite common lately.

The concept is that a slight curvature offers an immersive viewing experience on a larger screen. However, this Sceptre has a greater curvature than many others. And as a VA panel, you get really powerful color, contrast, and viewing angle, all at an amazingly low price.

Detailed Review of the Sceptre C355W-3440UN

A) Design

From a design perspective, Sceptre used the latest technology. Besides the 1800R curve, it has specifications similar to standard gaming monitors (including a 4ms G2G response time, Adaptive sync, and VA panel), but it also increases the panel refresh rate to 100Hz, making it an industry pioneer in offering a higher frame rate than we have seen previously in its 27″ predecessor.

  • Furthermore, the Sceptre C355W-3440UN offers the excellent aesthetics that one would expect from a gaming monitor.
  • Although it was designed with gamers in mind, it lacks the aggressive, bold, edgy styles of competitors like the 34GL750-B from LG.
  • Instead, the monitor housing is crafted from a dark gray plastic supported by a V-shaped stand.
  • The only real allusion to the player’s aesthetics is an illuminated “star” on the back, which breaks the black monotony where the bracket on the monitor is attached.
  • The stand offers tilt adjustment only (5° forward and 15° backward), but it lacks the swivel and height settings usually found in this price range.

B) Image Quality

The Sceptre C355W-3440UN monitor is based on a 35-inch VA panel with a 3000: 1 static contrast ratio, a maximum brightness of 250 nits, support for 8-bit color depth, and an sRGB color space of around 90%.

  • You won’t get such vivid or precise colors compared to ultra-wide IPS. Still, you get a higher contrast ratio, resulting in deeper blacks and a more vibrant ratio between the lightest and darkest tones.
  • Nonetheless, the colors of the Sceptre C355W-3440UN look great; it is bright enough under standard viewing conditions. It is an absolute pleasure to play content in dark scenes where you can really enjoy the high contrast ratio of the monitor.
  • Additionally, the 3440 × 1440 screen resolution means a 94.19 PPI pixel density when viewed on the 35″ screen of the C355W-3440UN and lots of screen real estate and crisp text and detail with no scaling needed.

C) Performance

The Spectre C355W performs well as an all-purpose monitor, perfect for the office, and shines easily as a gaming monitor.

  • It uses a resolution panel of 3440 x 1440 to deliver crisp images and vibrant colors with a refresh rate of 100 Hz, a contrast ratio of 320 cd/m2, and a response time of 4ms.
  • That’s a solid specification sheet for a big screen monitor at this price point. Incorporating AMD Freesync support makes things even better for avid gamers.
  • The 1800R of monitors offers an exhilarating experience and is pretty much a standard among the widescreen monitors gaining popularity recently.
  • The VA (Vertical Alignment) technology used for the display enables improved colors and wide viewing angles.
  • Adaptive-Sync technology aims to eliminate screen stuttering and tearing while gaming. Whether you use it for general productivity or office work, you’ll appreciate the 21:9 aspect ratio and smooth curve that makes it convenient to use.
  • If you are a casual gamer and don’t need the best frames per second, this is another factor to consider.
  • And for gamers who want to play the latest AAA games at super-high settings they can always look for high-resolution alternatives, such as the 34″ Alienware AW3420DW with 1ms response time, 120 Hz refresh rate, 1900R curvature, and Nvidia G-Sync.

D) Connectivity

There are 1 HDMI 2.0 port, 2 HDMI 1.4 ports, and a DisplayPort on the back of the case.

  • The Sceptre C355W-3440UN is equipped with at least one USB port, which provides additional charging power for smartphones and other devices.
  • A 3.5mm audio jack means you can plug your gaming headsets or headphones directly into the monitor instead of connecting a cable to your PC.
