Some weeks ago, when we tested a sample unit of the new Acer Aspire V15 (V3-574), we introduced you to its BluelightShield display technology and PWM results. Now, after the official release, we took a store unit and put it through the same tests to see if Acer has changed its display panel. It turned out that its the same LG Display (LP156WF4-SPL1), and we can confirm that the model uses Pulse-Width Modulation.

Fortunately, the flickering frequency is very high (25 KHz), so chances are you won’t feel eye fatigue even after continuous use. Also, at 100% brightness the display is just pulsating (as you can see in the graph below) and at that level the brightness is 240 cd/m2, so it’s not that much and is thus comfortable for everyday use.

If you haven’t read our PWM article and you’re not familiar with the technology, check out this post on the topic right here:
