VIOTEK GN34C Ultrawide QHD Curved Monitor REVIEW

I have been an avid fan of LG monitors for some time. One of my TV’s is an LG and in my opinion, it has the best blacks in the market. For the past few years, my office monitor has been an LG (34-inch ultra wide) and while it’s been a really nice monitor, this VIOTEK monitor is taking its place. Even though the aforementioned LG monitor was an ultra-wide monitor, it was not curved and that is something I’ve really wanted to introduce to my setup for some time. Another factor that pushed me to upgrade my monitor to the VIOTEK was that the LG was only 60 hertz whereas the GN34C is 100 Hertz. It was definitely time for a change.

So how is the quality of a monitor that costs half the price of my beloved LG? It’s surprisingly great with some issues of course. The operation buttons are impossible to see as are the input ports. There is no real cable management included with the monitor stand and the cables hang down from the bottom of the monitor. This is something that bothers me a great deal as I hate cable clutter. I have worked out an option for hiding the cables, but I would have loved to see this be included with the stand or even on the back of the monitor itself.

Because sometimes I connect my monitor to a MacBook Pro with only USB-C ports available, I have to connect the display using a dock. I was coming from a Thunderbolt 2 monitor, which included a lot of ports but when you are using a dock or a PC, the extra ports are not a must-have. I chose to connect to the VIOTEK monitor using a Display cable so that I could get the full HD/4K option as a video signal. When it comes to bezels this monitor is as close to none as you can get. Yes, it has a bezel at the bottom but the sides and top are hardly there. This is a really nice improvement from my LG. I have also been enjoying the GN34C’s curved design. There are no reflections and 100 Hertz refresh rate is outstanding. I’ve used the monitor for a variety of productivity tasks (email, word processing, etc.) as well as graphically intensive production tasks like photo editing and video editing, and the all important gaming. The monitor has provided the wide color gamut I desire and visual performance I’ve needed from a monitor.

In addition to standard performance testing, I also used MotionMark to obtain a graphics benchmark for the monitor. Since I was using the Late 2018 MacBook Pro for this test, I was able to test it in four different ways — 60Hz with the Standard GPU, 100Hz with the Standard GPU, 60Hz with the Vega Pro 20 GPU, and 100Hz with the Vega Pro 20 GPU. As you can see from the screenshots included above, there is a significant performance spike when using the more advanced GPU for graphics performance with high-quality monitors.

Even though my primary uses of this monitor include professional business tasks I did test it out with a few games. I connected my XBox One X to the monitor and played Player Unknown Battlegrounds and Mortal Kombat. I thought both of these games were diverse enough — both in graphics and movement — that they would be a good test for the FreeSync feature. The picture was beautiful and immersive thanks to the curved display. Gameplay was smooth and the picture remained gorgeous throughout my gaming experience.
