In-Depth Review: SANSUI 34-Inch Curved Gaming Monitor (ES-G34C5) – A Feature-Packed Ultrawide Contender

The SANSUI ES-G34C5 is a 34-inch curved ultrawide gaming monitor that blends performance, immersive visuals, and affordability


With a 3440x1440 UWQHD resolution, 165Hz refresh rate, 1ms MPRT response time, and wide color coverage including sRGB 125% and DCI-P3 95%, it enters the growing category of ultrawide monitors designed for gamers, creators, and multitaskers alike.


This review evaluates the monitor's core strengths and technical features, while also exploring its practical use in gaming, productivity, and entertainment. Let’s dive deep into what makes the SANSUI ES-G34C5 stand out in the competitive ultrawide market.


1. Display Resolution & Panel Type

The SANSUI 34-inch curved gaming monitor offers an Ultra-Wide Quad High Definition (UWQHD) resolution of 3440 x 1440 pixels. This 21:9 aspect ratio is significantly wider than traditional 16:9 monitors, allowing users to see more on-screen at once, which is particularly advantageous in strategy games, racing simulators, immersive shooters, and productivity scenarios like video editing or multitasking workflows.


The panel type is Fast VA (Vertical Alignment), which typically delivers superior contrast compared to IPS panels. VA panels excel in displaying deep blacks, making them ideal for dark scenes in games or movies. While VA panels are known to have slower response times, SANSUI compensates for this with 1ms MPRT, effectively eliminating motion blur when paired with backlight strobing technologies.


2. Refresh Rate & Responsiveness

One of the most crucial specifications for a gaming monitor is its refresh rate — and at 165Hz, this SANSUI monitor stands well above standard 60Hz or 75Hz displays. A higher refresh rate leads to smoother motion transitions and enhanced gameplay responsiveness, especially in fast-paced games like Call of Duty, Valorant, or Forza Horizon.


The monitor also boasts a 1ms (MPRT) response time, which is essential for reducing ghosting and blur during fast movement. This quick response ensures each frame appears clean, which can provide a competitive edge in reaction-based gaming scenarios.


Combined with AMD FreeSync support, the monitor synchronizes its refresh rate with your graphics card’s output to eliminate screen tearing and stuttering — a must-have feature in modern gaming hardware.


3. Curvature & Immersion

This monitor features a 1500R curvature, providing a more natural field of view than flatter ultrawide monitors. This curvature aligns more closely with the human eye, increasing immersion by wrapping the screen gently around your peripheral vision.


The 1500R curve works exceptionally well on a 34-inch screen, enhancing spatial awareness in gaming and contributing to a cinematic feel when watching movies. For productivity, it reduces the need to turn your head, making it easier to work across multiple windows or timelines in content creation software.


4. Color Accuracy & HDR Support

Color performance is a major highlight of this model. With sRGB 125% coverage and DCI-P3 95%, the monitor goes well beyond typical consumer displays, offering vibrant, rich, and accurate color reproduction. This makes it suitable not only for gaming, but also for light content creation tasks like photo editing, video editing, and graphic design.


The 8-bit color depth provides 16.7 million colors, sufficient for most applications, while HDR (High Dynamic Range) support enhances the contrast and depth of content, especially in compatible games and video. While the brightness level caps at 300 nits, which is moderate, it's still bright enough for most indoor environments.


HDR visuals appear more dynamic, with improved brightness levels in highlights and better detail retention in shadows — although it won’t compete with true HDR600+ displays, it still offers noticeable improvement over SDR (Standard Dynamic Range) monitors.


5. Ergonomics & Design

Physically, the monitor is designed with an elegant yet functional appearance. It features tilt support (-5° to +15°) for viewing comfort and is VESA mount compatible (75x75mm), allowing users to mount it on an adjustable arm or wall bracket for better ergonomics.

The monitor includes a Kensington Lock slot, enabling security in shared workspaces or public settings. However, height, pivot, or swivel adjustments are not available on the included stand — so users wanting more flexibility may prefer using a third-party mount.

With 178° viewing angles, the VA panel performs well even when viewed from wide angles, maintaining color and brightness consistency for collaborative viewing or multi-angle setups.

6. Connectivity Options
The SANSUI G34C5 monitor includes a good selection of input ports:

Two HDMI ports (up to 100Hz)

Two DisplayPort 1.4 ports (up to 165Hz)

One 3.5mm headphone jack

The use of the DP 1.4 port enables full 165Hz performance at 3440 x 1440 resolution, which not all HDMI ports support, especially on older devices. HDMI ports are useful for connecting gaming consoles or secondary computers, although they are limited to 100Hz.

The inclusion of Picture-in-Picture (PIP) and Picture-by-Picture (PBP) modes enhances productivity by allowing multiple input sources to be displayed simultaneously—an essential feature for streamers, developers, or users managing multiple systems.

However, the monitor lacks built-in speakers. While this isn't a major drawback, it means you'll need to use external speakers or headphones to output audio.

7. Build Quality and Accessories
The SANSUI ES-G34C5 monitor features a durable design, sleek lines, and slim bezels that maximize screen space. The matte finish helps reduce reflections and glare, enhancing usability in well-lit environments.

The box includes all essential accessories:

DisplayPort cable (1.5 meters)

Power adapter

Power cord (1 meter)

User manual

This ensures quick setup right out of the box without the need to purchase additional cables—a thoughtful addition, especially for first-time buyers.

8. Eye Comfort Technologies
To address the strain caused by long hours of screen use, the monitor incorporates Flicker-Free and Blue Light Reduction technologies. These technologies reduce eye strain and visual fatigue, which is critical for gamers and professionals who spend long periods in front of their screens.

Whether you're playing video games, attending meetings, or working on spreadsheets, these features contribute to a more comfortable and pleasing viewing experience.

9. Monitor Versatility

For Gamers: The ultra-wide format provides a tactical advantage with a wider field of view and an immersive gaming experience. High refresh rates and low latency help ensure peak performance.

For Content Creators: The wide color gamut and QHD resolution deliver detail and vibrancy ideal for editing and visual design work.

For Professionals: The extra horizontal space allows for seamless multitasking with side-by-side windows or productivity dashboards.

For Entertainment: Watching movies in a 21:9 format creates a more cinematic feel without the need to display the large details found on standard monitors.

The Bottom Line:

If you're looking for an affordable ultra-wide monitor that maintains color accuracy, responsiveness, and immersion, the SANSUI ES-G34C5 is an excellent choice that punches above its weight class.
