OSD Setup & Calibration
The Optix MAG24C’s joystick allows one to zip through menus with ease and also toggles power and offers quick access to input selection and picture modes. Pressing it once engages the full OSD.
Picture modes are found in the first sub-menu, Game. There are only five, but given our experience, that is four too many. The Standard mode is the only one that leaves all options available, and it’s perfectly suited for gaming and productivity. Also in this is dynamic contrast, a FreeSync toggle, aspect control, a set of crosshairs and overdrive. That last one is interesting. When using overdrive, the mode selection and brightness slider are grayed out. Meanwhile, brightness output is locked at around 146 nits, which is a little dim unless you’re playing in the dark. You can still change gamma and color temp while using overdrive though. However, we found no need for overdrive at high frame rates.
Image controls are basic but complete. There are two fixed color temps, plus a user mode with RGB sliders that begin center-range. Achieving good white balance is easy, and you won’t give up any of that wonderful VA-panel contrast. Gamma options are only 1.8 and 2.2.; we wish there were a 2.4 setting since there is over 3000:1 contrast available.
After the input selector, there are just a few setup options. You can change the OSD language, set the MAG24C to power off when there’s no signal, turn off the LED lighting effect and return all settings to their factory defaults. Signal info always appears at the top of each menu and shows resolution, refresh rate, picture mode, FreeSync status and current input.
While the essence of simplicity, the OSD has one flaw. It’s so large that it covers the center of the screen, making it hard to take measurement. This won’t be an issue if you don’t calibrate with an instrument.
Calibration
The Standard picture mode allows for white balance calibration and has two gamma presets. 2.2 is the default, and it measured accurately. Initial grayscale readings show a green tint that was visible to the naked eye. A few tweaks of the RGB sliders took care of that. Color is fixed at over 80% of the DCI-P3 gamut, so brighter material appears oversaturated. There is no sRGB option, but most content looked fine (we’ll give you more detail on page four). After our calibration, we measured decent performance, certainly beyond expectations for a $250 monitor.
As noted above, you’ll need to leave Response Time off if you want access to the Brightness slider. Here are our recommended settings:
