For most end-users, the way a screen performs out of the box (with basic adjustment) is very important. Not having access to dedicated colorimeter tools, tweaking the monitor’s color fidelity and luminance is out of the question.
As such, the screen was tested at default settings using an X-Rite i1 Pro spectrophotometer, combined with Spectracal’s Calman software suite. An X-Rite Display Pro colorimeter was used to verify the black point and contrast ratio separately.
Out of the box – the monitor comes with the standard eColor preset mode, which has fairly good image quality without additional tweaking – though a bit too bright for my eyes, particularly in a dark office environment. The luminance registered was 267cd/m2, a light intensity that will certainly cause issues to most end-users.
The color accuracy was good, but not exceptional, with an average dE of 3.0 and a relatively smooth transitions between gradients.
Static contrast ratio however, was damn exceptional, and the measurement indicated a 1067:1 standard, far better than what most gaming monitors offer.
Following the calibration, the average gamma was corrected to a 2.2 average – with a deviance of less than 1%, which is not really visible to the naked eye. Luminance had also been adjusted to a standard of 120cd/m2 – which brought the black point of 0.11cd/m2 and a similar and excellent static contrast ratio of 1075:1.
As one might expect, the viewing angles for an IPS panel are pretty good all the way through. A slight color shift happens for angles past 45°, as well as a visible darkening of the image at wider angles.
While the shift is visible, it’s nowhere near as noticeable as it might be on similar TN film panels, especially on the vertical plane. After all, for curved screens, excellent viewing angles are a must.
As always, we measured the screen uniformity using X-Rite’s I1 Display Pro colorimeter – calibrating the central point at 220 cd/m2, then measuring 8 surrounding sections. The most noticeable difference was in the upper left corner, which was about 15% darker than the rest of the screen.
Worth noting is that panel uniformity is a unique variable for each monitor, and it can vary from one unit to another.
Unlike's NVidia's G-Sync technology, AMD's FreeSync builds on top of industry standard technology, which means no license, proprietary hardware or hardware costs on the manufacturer end. As the monitor supports a max refresh-rate of 75Hz, the FreeSync range sits between 30-75Hz. The real benefits are noticeable in the lower end, between 30-60Hz.
If the output goes over 75FPS, you have the option for the screen to behave either as V-Sync is on or off, outside of the FreeSync range. Tearing is not as dramatic at high refresh-rates, so you use FreeSync between 30 to 75Hz, and have V-Sync do its thing for everything over 75 FPS.
When it comes to power-consumption, Acer lists the average usage at 42.5W, and 0.5W in stand-by. So, I decided to test these figures out of the box - and it needed 47.9W at the default brightness. Once calibrated at 120cd/m2 the consumption went down to 32.2W - and in stand-by it actually used only 0.5W.
