AOC Unveil Q27G4SL/WS a 27″ 320Hz QHD Fast IPS Circular Polarised Eye-Protecting Monitor

AOC’s Q27G4SL/WS has been launched in China, offering a 27” ‘Fast IPS’ panel, 2560 x 1440 resolution and 320Hz refresh rate. It also features Circular Polarised technology which helps reduce reflections and eye strain. Hot on the heels of another monitor from Philips, their 27M2N3500UK, this will only be the second monitor to feature this technology. Furthermore, the AOC model will be the world’s only 320Hz gaming monitor that boasts certification under the TÜV Rheinland ‘Circular Polarisation’ scheme.

According to AOC’s website “Circular polarised light technology simulates natural light and restores the comfortable and healthy visual experience brought by natural light.” This means that the light emitted from the monitor should apparently closely resemble that of natural light which can provide users with a healthier eye experience and more comfortable viewing experience.
