Viotek GNV34DBE2 Ultrawide Gaming Monitor Review

Viotek GNV34DBE2 Ultrawide Gaming Monitor Introduction

Today’s article features the Viotek GNV34DBE2 34-inch QHD ultrawide curved gaming monitor. Viotek is an Indiana-based company focused on displays and gaming monitors, building an impressive product portfolio over the past decade. The company offers a wide range of monitors at a very competitive price point, especially when it comes to larger displays with high resolutions.

Viotek’s latest UW-QHD flagship sports a large, curved VA panel with 3440 x 1440 resolution, a 21:9 aspect ratio, and a max refresh rate of 144Hz. Other notable features of the GNV34DBE2 include VESA compatibility, 1ms MPRT/6ms GTG (OD) response time, a maximum brightness of 350 cd/m², 99% sRGB/85% NTSC color gamut, a contrast ratio of up to 4000:1, 1500R curvature, and Adaptive Sync/G-Sync/FreeSync compatibility.


The GNV34DBE2 is currently listed on the Viotek official webstore for the bargain price of $379.99 USD. That said, the monitor seems to be out of stock at the major retailers I usually check, even eBay is sold out! Not a big surprise considering the impressive specs and aggressively competitive price point. Let’s take a closer look and see why this little monster is so wildly popular.

Viotek GNV34DBE2 Ultrawide Gaming Monitor Closer Look & Assembly

The Viotek GNV34DBE2 comes in a standard cardboard box showing the brand, product name, and monitor size. The monitor and accessories are neatly organized inside with ample padding.

Aside from the actual panel, we get a user manual, a DisplayPort cable, and a power cable. In terms of hardware, Viotek provides a red headphone clip, a few screws, and a screwdriver. The included base and stand are of the utilitarian sort, just enough to keep the monitor off your desk without any fancy adjustments beyond some tilt. I personally prefer using third party mounting arms when possible, so a no-frills base that doesn’t drive the price up needlessly is more than welcome.

Assembling the Viotek GNV34DBE2 was a simple affair that took just a few minutes. I usually discard any included tools in favor of using my own screwdriver set. The bundled screwdriver however is of excellent quality, so I used it while working on this review. Granted, the actual assembly requires only three screws to complete but its nice to have all the needed hardware in the box. First, I secured the stem to the base using one of the screws from the bag number one, then I attached the headphone clip to the top of the stem as shown in the user manual. Next, I placed the monitor face down on my worktable and removed the adapter located on the back of the unit. Doing so reveals the mounting mechanism and allowed me to easily secure the adapter to the assembled base.

The last step involves attaching the base/adapter assembly back to the monitor and gently setting the unit upright. Viotek equipped its latest 34-inch flagship with a ring of red LED lights for some gamer bling. The LEDs can be turned off from the OSD if a more sober look is your thing. I left the lighting as is since the LEDs are just bright enough to give a little red haze behind the monitor in low light conditions and are otherwise unnoticeable.

The Viotek GNV34DBE2 sits at roughly 455mm high when fully assembled, with about 90mm clearance between the desk and the bottom of the monitor. The low-profile base allows for a -5 to 15 degrees adjustment, but no sideways swivel or height adjustment are possible. As is, the monitor should be perfectly usable for most users. For those needing more adjustment flexibility, the unit is VESA 75x75mm compatible which should open up many options for wall and desk mounting. A gas spring arm (for example) would be a great addition to this monitor. It’s also worth mentioning that the design of the base allows the monitor to be pushed close against the wall, which can help in freeing up more desk space for other peripherals. I’ve had some major issues before with a few high-end monitors that came with bulky stands that would take up precious real estate just by sitting pretty much in the middle of the desk.

Viotek equipped the GNV34DBE2 with a decent selection of connectivity options. Under the removable cover, we find two HDMI 2.0 ports, two DisplayPort 1.4 and a 3.5mm audio out. The monitor power circuitry is integrated which saved me from figuring out how to hide yet another power brick under my desk.

Viotek GNV34DBE2 Ultrawide Gaming Monitor Setup & Experience

After connecting the monitor to the test system running the mighty NVIDIA GeForce RTX 3090 FE, I fired everything up and took a look at what the OSD (on-screen display) has to offer. Before we go any further, keep in mind that HDMI 2.0 is limited to 3440x1440p at 100Hz refresh rate, or 2560x1080p at 120Hz refresh rate. In other words, using the DisplayPort 1.4 will be mandatory in order to take advantage of the Viotek GNV34DBE2's max resolution of 3440x1440p at the max refresh rate of 144Hz. Another thing worth noting here is that the following pictures show the factory default settings of the monitor. The only thing I had to change was max out the OSD time out duration so I can take pictures without having to fiddle with the buttons every 20 sec or so.

The Viotek GNV34DBE2 has five clicky buttons located under the bottom-right corner of the display. The buttons are easy to access, and I figured out the optimal way of pressing them after a few tries. From left to right, we have the M (menu or enter/select), down, up, E (exit or back/previous), and power buttons. While pressing the Menu button pulls up the full OSD, there are a couple important shortcuts that are worth mentioning before we go there. First, pressing any of the left four buttons will display the navigation menu (as Viotek calls it). From here, pressing the E button seems to be the only way to cycle between the limited and full RGB range, which is set to Limited by default. The next shortcut, labeled "eco" in this retro looking OSD, allows us to cycle through the various picture modes including RTS, FPS, Standard, Photo, Movie, and Game. Lastly, pressing the down button will activate Gameplus mode. Here users can choose between four different crosshair types: a red +, a green +, a red dot, and a green dot. 

Pressing the M button will display the actual OSD and gives access to various menus and sub-menus. The fist menu is a simple input selection list that shows the available HDMI and DisplayPort ports.

The next two menus give access to brightness, contrast, and color settings. At this level, it's part common sense and mostly user preference, although I suggest lowering the brightness level a bit. In the Color Setting section, users can adjust various settings including the Gamma, picture mode and color temperature.

The Picture Quality Setting menu offers a few interesting options including Response Time, which allows to set the monitor overdrive feature. A few other options are worth exploring such as Super resolution and MPRT (Moving Picture Response Time). The Display menu lets you pick the aspect ratio from wide screen, 4:3, 1:1, and auto. The LedMode option is there if you wish to turn off the light ring on the back of the monitor.

The audio menu provides a measure of control for the onboard 3.5 mm audio output. The multi-window menu on the other hand holds the settings for the PIP (Picture-in-Picture) and PBP (Picture-by-Picture) features. Here users can select the secondary input type alongside the size and position of the PIP picture. The available sizes are small, medium, and large. The PIP can be positioned top right, top left, bottom right, or bottom left.

image image

Finally, we have the OSD and Other menus. The options in the OSD menu give access to language selection and OSD position, time out, and rotation. In the last menu, labeled other, users can change the DisplayPort version, switch Adaptive-Sync or HDR on and off. Here is also located the reset function for bringing the monitor back to factory settings.

After playing with the OSD for a while and setting the monitor according to my preference, I wanted to check the PIP and PBP features. I connected my trusty MSI GS65 Stealth Thin laptop as secondary source to one of the HDMI ports and set it to play some TenSura episodes. The PIP functionality worked as intended and might come in handy if a secondary input is absolutely needed for whatever reason, although I question the ideal use case scenario here. The PBP feature looked a bit off since it split the monitor into two separate displays, where everything was squished to fit the odd screen size.

Finally, I got to put the Viotek GNV34DBE2 to work for its intended purpose, which is glorious ultra-wide gaming. This 34-inch VA panel sports a 3440x1440p resolution and has a 1500R curvature, making it very pleasant to use without any noticeable strain. I tried a few of my favorite titles to get a feel of the monitor, including the latest Yakuza and Divinity Original Sin 2. The picture was clear, sharp, and had vibrant colors across the board. The latest Viotek flagship also offers 144Hz refresh rate and full support for Adaptive Sync/G-Sync/FreeSync compatibility, making it extremely versatile and future proof. No matter if you go with the green or red team for your next GPU, the GNV34DBE2 can handle it.

The large screen size and wide form factor are also optimal for media consumption and productivity. After a few tweaks in the OSD, the Viotek GNV34DBE2 showed excellent color reproduction and picture quality in bright and dark scenes when watching videos. The 21:9 aspect ratio is absolutely amazing for watching movies without black borders and the 34-inch screen size allows for multiple programs to be open side by side with room to spare.

At $379.99 USD, the Viotek GNV34DBE2 represents tremendous value for the price. It's hands down one of the best ultrawide 34-inch 3440x1440p 144Hz curved monitors. Highly recommended if you want to game in UW-QHD without breaking the bank!
