The Koorui 27E6QC is one of the best gaming monitors you can get for under $200, provided that you’re not too sensitive to dark level smearing.
If you’ve been looking for an affordable 27″ 1440p high refresh rate gaming monitor, the Koorui 27E6QC might just be for you!
The Koorui 27E6QC is based on an 1800R curved VA panel with a high 3,000:1 static contrast ratio, which provides you with deep blacks.
In fact, IPS monitors with the usual 1000:1 contrast ratio have somewhat grayish blacks in comparison, besides suffering from IPS glow, so the Koorui 27E6QC definitely offers a more immersive viewing experience, especially in dark rooms.
Naturally, IPS monitors have their own advantages in this price range, such as significantly faster response times.
IPS displays also have wider viewing angles despite having the same 178° specification as the VA models such as the Koorui 27E6QC, which exhibits minor gamma/saturation shifts when looking at the screen at certain angles.
However, this isn’t an issue during everyday use (or basic content creation), but it’s worth keeping in mind if you plan on doing professional color-critical work.
Moving on, the monitor has an 85% DCI-P3 color gamut coverage with a ~125% sRGB relative gamut volume. As a result, you get rich and punchy colors. This also means that sRGB content will be over-saturated, but most users will prefer the extra color vibrancy as the over-saturation is not too intrusive.
There’s no sRGB emulation mode available in the OSD (On-Screen Display) menu, but you can use the Custom Color option in the Radeon driver settings if you have an AMD GPU, or the novideo_srgb tool in case you have an NVIDIA graphics card to clamp the gamut via software.
Next, the Koorui 27E6QC monitor has a peak brightness of 250-nits, which is the minimum as far as modern LED-backlit displays go. However, it can still get more than bright enough under normal lighting conditions.
If you plan on using the screen in a particularly bright room (with studio lighting, for instance) or facing a window without any blinds or curtains, you should look for a brighter monitor instead.
Further, the 2560×1440 Quad HD resolution suits the 27″ sized screen of the monitor very well. You get 108.79 PPI (pixels per inch), which results in sharp details and text.
1440p is also significantly less demanding on the GPU than 4K UHD and you still get plenty of screen real estate.
The Koorui 27E6QC has two response time overdrive modes: On and Off.
Make sure that overdrive is set to On for the best performance. However, since it’s using a VA panel, some ghosting and dark-level smearing will be noticeable behind fast-moving objects.
For most gamers, the amount of ghosting will be tolerable or even negligible, but if you’re particularly sensitive to this visual artifact, you should consider an IPS model with faster response times instead. Input lag performance, on the other hand, is not an issue with ~5ms of delay, which is imperceptible.
Further, the monitor supports variable refresh rate via AMD FreeSync and NVIDIA G-SYNC Compatible with a 48-144Hz dynamic range for tear-free gameplay up to 144FPS.
While it doesn’t have official certifications, VRR works without issues except for occasional brightness flickering in games with unsteady frame rates, which is common for most high refresh rate displays, especially those with VA and OLED panels.
In addition, you can enable the MPRT option in the OSD (On-Screen Display) menu, which uses backlight strobing to reduce perceived motion blur at the cost of image brightness, though it can’t be active at the same time as VRR.
MPRT also introduces screen flickering that’s invisible to the human eye but can cause headaches after prolonged use to those sensitive to flicker. The backlight is otherwise flicker-free and there’s a low-blue light mode available.
At the rear of the monitor, there’s a directional joystick for quick and easy navigation through the OSD menu.
Besides the standard image settings (brightness, contrast and color temperature), the Koorui 27E6QC also offers two gamma presets, but it lacks sharpness, Black Equalizer, saturation and automatic input detection support.
Other features include on-screen timers, an off-timer, crosshair overlays, various picture presets and display scaling (16:9, 4:3 and auto).
Design & Connectivity
The stand of the monitor is fairly sturdy, but it’s tilt-only by -5°/15° as far as the ergonomics go. Luckily, the screen is VESA mount compatible via the 75x75mm pattern.
Next, the screen has a subtle 1800R curvature for added immersion and there’s a light matte anti-glare coating that prevents reflections without making the image too grainy.
Connectivity options include DisplayPort 1.2, HDMI 2.0, HDMI 1.4 (limited to 75Hz at 2560×1440) and a headphone jack.
Price & Similar Monitors
The Koorui 27E6QC can usually be found for just $170, which makes it one of the most affordable 1440p high refresh rate gaming displays. It’s also available with a flat-screen panel as the Koorui 27E1QA.
If you’re looking for something similar, check out the Acer XZ270UP with a steeper 1500R screen curvature, a slightly higher 165Hz refresh rate and a fully ergonomic stand – though it doesn’t have as wide color gamut. It can also be found for $170.
