Controls and OSD

The Gigabyte GS34WQC uses a four-way joystick, which also works as a button for OSD navigation and monitor setup. You can use it to quickly access settings such as factory picture profiles, virtual crosshairs/timer/FPS counter, and input selection, or to dive into the main menu, where you can adjust everything that the OSD has to offer. As usual, the four-way joystick is an intuitive method of moving around the OSD.


After diving into the OSD settings, you'll find yourself in the Gaming section. This is where Gigabyte grouped gaming-related technologies, such as overdrive (speeds up pixel transitions) and Aim Stabilizer (backlighting strobing to achieve a "1 millisecond-like" response time at the expense of picture brightness), Black Equalizer (boosts dark areas), and AMD FreeSync Premium, which turns adaptive synchronization on and off, working with both AMD and NVIDIA graphics cards.


In the Picture submenu, you first have to select a picture profile you want to edit. The factory picture profiles are called Standard, Gaming, Movie, Reader, sRGB, Custom and ECO. The latter is the default picture profile. Most options found here are what you'd expect from a decent PC monitor: brightness, contrast, color vibrancy, sharpness, gamma, color temperature (Cool, Normal, Warm, and User Define), blue light filtering and dynamic contrast.


The Display submenu offers input selection, RGB range selection (0–255, 16–235, or Auto), and the Overscan feature, which slightly enlarges the image to hide the outermost edges. Here's where you'll also "overclock" the panel, by unlocking the maximum 135 Hz refresh rate. This feature worked with no issues on my sample of the Gigabyte GS34WQC.


In the PIP/PBP menu, we can select the Picture-in-Picture and Picture-by-Picture signal sources, size and location of the secondary PiP window, swap the chosen signal inputs around, and change audio sources if both inputs are outputting sound.


In the System submenu, we can adjust the OSD display time, size, and transparency, change the quick settings (options accessible by pulling the joystick in any of the four directions without accessing the main menu), turn off the front-facing LED, activate automatic input switching, and so on.


The OSD also lets us select the interface language and reset all settings to factory defaults.
