The Viotek GN27D promises a lot. It’s the flat-panel version of the curved monitor from Viotek, and features a TN panel, with an ultrawide monitor, which makes it ideal for gaming. If you’re looking at the best computer monitor for general use or even for gaming, this could just be it—with a 27” screen, 144 Hz refresh rate, 1440p resolution, and FreeSync.


The ideal situation would be buying an ultrawide gaming monitor, unpacking it, and switching it on to find that the default performance is just what you need. Unfortunately, that doesn’t happen in the real world, and the Viotek GN27D isn’t any different.

Out of the box, it has a red tint. It is not calibrated at the factory for gaming at all. However, the QHD resolution display would render quite nicely for professional work, so if you plan to use it at your desk for more than just gaming, you might be happy.

After calibrating, everything is much better on this 1440p 144hz monitor. The viewing angles provide some contrast shift, so for the best experience, positioning the monitor in front of you with the correct tilt is recommended to counteract any dead pixels. However, this monitor still suffers from poor contrast ratio in aspect ratio at extreme angles much less than other brands.

This monitor regularly performs better than it’s advertised peak brightness of 220 nits. The ms response time is a huge benefit to having a TN monitor. Three-millisecond standard response time with a one millisecond response time in overdrive will get you where you need to be.

Input lag may record about four milliseconds of latency, which makes for a very fast monitor for gaming. The colors give you 100% TGB coverage and 92% DCI-P3 coverage, which is pretty impressive for a curved screen.


The design of the Viotek GN27D is relatively simple and minimalistic. The main monitor frame is made of plastic, and the matte coating is a little grainy. This consistency isn’t unusual for a TN monitor, and the three-prong metal stand looks stylish.

There’s also a red light on the back of the monitor. Aside from that, there’s no obvious gamer style, which many appreciate so they can use their monitor for more than just online warfare. In keeping with its basic style, there’s not a lot of fancy adjustments you can make. It tilts, but it does not swivel or change the height.

Standard ports include a generous helping of three HDMI ports, one DisplayPort, and a headphone jack. It also comes with a pair of 2W built-in speakers that leave much to be desired.


The Viotek GN27D is a great value for anyone who wants a fast gaming monitor. If you care little about the design and much about the internal components allowing you to play effortlessly, then this is the one.

It sits right in the sweet spot between the best color contrast of any other TN monitor, excellent screen refresh rate, and simple affordability. It’s not a high-priced gaming monitor with all the frills, but it’s the best TN monitor on the market.


If you’re looking for a gaming monitor, this is by far the best TN monitor you can buy. However, out of the box, it’s also calibrated nicely for a work environment. You can enjoy a dual-purpose monitor at an affordable price with this one.
