Controls and OSD


The Viotek GFV27DAB utilizes a small four-way joystick that also works as a button for OSD navigation and monitor setup. It is located on the right side, behind the panel. The joystick lets you quickly access various settings (factory picture profiles, input selection, headphone volume, virtual crosshairs, timer, and FPS counter) as well as dive into the main menu and browse through the various options divided into six categories. The joystick is exceptionally intuitive to use, and the overall OSD layout is solid and easy to navigate.


The Display submenu contains the most common settings related to picture quality, such as brightness, contrast, factory profile selection (Sm²ndard, User, Movie, Photo, RTS, FPS1, and FPS2), aspect ratio, sharpness, and black equalizer. The latter can be interesting if you want to boost the black color gain to make your enemies hiding in the shadows easier to spot. Of course, doing so effectively ruins the picture quality as you're destroying contrast and perceived color depth.


The Color submenu contains settings such as color temperature (Normal, Cool, Warm, sRGB, and User), Gamma (Off, 1.8, 2.0, 2.2, and 2.4), hue, saturation, and low blue light; essentially a blue light filter to reduce eye strain when using the monitor in the nighttime, it make the picture look yellow. Luckily, you can choose the amount of blue light filtering (0, 25, 50, and 100), so try removing it partially to see if that helps with your headaches and eye fatigue. Most users should leave this option at 0.


The Gaming Setup submenu is where you can activate or deactivate FreeSync/G-SYNC, adjust overdrive (Off, Low, Middle, and High), check out the virtual crosshairs, timer, and framerate counter, and toggle stuff like HDR, dynamic contrast, MPRT, and RGB Light (the aforementioned LED ring found on the back of the monitor). This monitor doesn't meet the technical requirements for a proper HDR experience, so don't bother with it. As for the ideal overdrive setting and Moving Picture Response Time (MPRT) implementation, we'll examine both in the gaming performance section of this review.


The Input submenu is where you can switch between the three available video inputs. You can do the same through the quick menu without venturing into the full OSD by pushing the joystick up while OSD isn't active.


In the System Set submenu, you can change the OSD language and position, adjust the headphone volume, reset the settings, and update the monitor's firmware after inserting the appropriate firmware into the USB service port on the rear.


All OSD settings can be saved to and loaded from three onboard profiles as necessary.
